CAS Worldwide Homepage About CAS About CAS News The Center for Advanced Studies (CAS) was established at the IBM Toronto Lab in 1990. Its CAS receives 'Synergy Award Success stories mission was to strengthen the links between research communities and IBM. CAS has been for Innovation' CAS sites working closely with academic institutions, as well as corporate, government, and other IBM ACM-ICPC research groups on various projects that relate to the products of the IBM Toronto Lab.
High school outreach Because of the success of CAS Toronto, several IBM Laboratories and Research facilities around the world have opened their own Centers for Advanced Studies.
CAS was formed with five main objectives: Related links IBM University Relations To ensure timely and effective transfer of leading-edge research to IBM product development Programming Contest Central groups; IBM alphaWorks To provide academics with access to problems of interest to IBM developers; IBM developerWorks To enable collaboration among academia, industry, government and IBM research centres as DB2 for Academics well as IBM development labs; WebSphere for Academics To provide a venue for research sabbaticals; To become the leadership model within IBM and Canada for co-operative research.
The main emphasis of CAS research projects is solving problems of utmost importance to software developers. However, it also entertains proposals relating to other aspects of computer science, including those involving theoretical work. CAS is continually initiating long-term projects in collaboration with other members of the research community. The results of these projects vary from research publications to prototypes and new directions for products.

Smart Interactions The evolution of the internet in late 1990s focuses on web applications and deployment technologies in order to adapt to the challenges imposed by the inherent web architecture. Starting early 2000s, new technologies flourished to attempt to provide better user experience of the web. Rich Internet Application (RIA) aims at providing rich media for the web that is comparable to the desktop counter part (Allaire, 2002). Web 2.0 created the notion of "the web as a platform" to enable an architecture of participation; end user control and remixing of units of functions (O'Reilly, 2005). AJAX enables asynchronous interactions that offer new opportunities for user interactions (Garrett, 2005). Read more

Reaching project goals demands from team members the creation and communication of Related links detailed and vastly heterogeneous project information. Although no team member needs to IBM University Relations know every piece of project information, each of them depends extensively on knowledge Programming Contest generated by other parties.

An IDE for Software Development Using Tabular Expressions
Dennis K. Peters, Memorial University; Mark Lawford, McMaster University; Baltasar Trancón y Widemann,University of Limerick
In this paper we present preliminary work on an IDE for formal software development using tabular expressions as the basis for precise specifications and descriptions of software behaviour. Motivation for the work is provided by reviewing the use of tabular methods on the Darlington Nuclear Generating Station Shutdown Systems and discussing its perceived shortcomings. The proposed system's potential is demonstrated by the steps taken to integrate an Eclipse based GUI, with theorem prover based V&V and functional specification and code generation backends. We close with a discussion of related work and future research directions.

A Test Framework for Integration Testing of Object-Oriented Programs
Tom Maibaum and Zhe (Jessie) Li, McMaster University
A lot of research has been done in the field of testing object-oriented programs. However, integration testing forms only a small part of this work and few tools are available to implement the integration testing approaches. This paper presents a new integration testing approach for object-oriented programs and a prototype tool supporting the testing approach. Unlike previous approaches, the proposed technique generates test cases using the concept of Coordination Contract, a specification mechanism which superposes behavior on components without interfering with their implementations.

Support for OpenMP Tasks in Nanos v4
Xavier Teruel, Xavier Martorell, Alejandro Duran, Roger Ferrer and Eduard Ayguadé, Barcelona Supercomputing Center — Universitat Politécnica de Catalunya
In this paper we describe an implementation overview of Nanos v4: an OpenMP Run Time Library (RTL) based on the nano-threads programming model. Our main goal is to discuss different aspects of the library development focusing on the implementation of a new feature introduced in the last OpenMP release: task support.
We compare the performance of our prototype implementation and the workqueuing model available on the Intel compiler with a set of kernel applications.
Back to top MultiLoop: Efficient Software Pipelining for Modern Hardware
Christopher Kumar Anand and Wolfram Kahl, McMaster University
This paper is motivated by trends in processor models of which the Cell BE is an exemplar, and by the need to reliably apply multi-level code optimizations in safety-critical code to achieve high performance and small code size. A MultiLoop is a loop specification construct designed to expose in a structured way details of instruction scheduling needed for performance-enhancing transformations. We show by example how it may be used to make better use of underlying hardware features, including software branch prediction and SIMD instructions. Back to top
SLA-Driven Business Process Management in SOA
Vinod Muthusamy and Hans-Arno Jacobsen, University of Toronto; Phil Coulthard, Allen Chan, Julie Waterhouse and Elena Litani, IBM Canada Ltd
This paper presents a vision to achieve end-to-end Service Level Agreement (SLA) management by facilitating the various stages of business process development using formally encoded SLAs. We argue for a distributed architecture for the execution of business processes, and develop a model to control the provisioning of business processes in this architecture based on high-level goals that can be specified independently of the implementation details of a process.

An Approach to Managing the Execution of Large SQL Queries
Meng Yabin, Pat Martin, Wendy Powley, School of Computing, Queen's University
Current database workloads consist of a mixture of short online transaction processing (OLTP) queries and large, complex queries such as those typical of online analytical processing (OLAP) systems. These resource intensive queries often monopolize the database system resources and negatively impact the performance of smaller, possibly more important, queries. We present an approach and prototype implementation for IBM DB2 Universal Database which manages complex queries that involves the decomposition of the queries into an equivalent set of smaller queries and then scheduling the smaller queries so that the work is accomplished with less impact on other queries.

Removing Manually-Generated Boilerplate from Electronic Texts: Experiments with Project Gutenberg e-Books
Owen Kaser, University of New Brunswick; Daniel Lemire, Université du Québec à Montréal
Collaborative work on unstructured or semi-structured documents often involves agreed upon templates containing metadata. These templates are not consistent across users and over time. Rule-based parsing of these templates is expensive to maintain and tends to fail as new documents are added. We investigate the case of the Project Gutenberg-TM corpus, where most documents are in ASCII format with preambles and epilogues that are often copied and pasted or manually typed. We show that a statistical approach can solve most cases though some documents require knowledge of English. We also survey various technical solutions that make our approach applicable to large data sets. Back to top
Identifying Fault-Prone Files Using Static Analysis Alerts Through Singular Value Decomposition
Mark Sherriff and Sarah Smith Heckman, IBM Corp. and NC State University; Mike Lake, IBM Corp.; Laurie Williams, NC State University
Static analysis tools tend to generate more alerts than a development team can reasonably examine without some form of guidance. In this paper, we propose a technique for leveraging field failures and historical change records to determine which sets of alerts are often associated with a field failure using singular value decomposition. We per-formed a case study on six major components of an industrial software system at IBM over six builds spanning eighteen months of development. Our technique identified fourteen alert types that comprised sets of alerts that could identify, on average, 45% of future fault-prone files and up to 65% in some instances.

Identifying Active Subgroups in Online Communities
Alvin Chin and Mark Chignell, University of Toronto
As online communities proliferate, methods are needed to explore and capture patterns of activity within them. This paper focuses on the problem of identifying active subgroups within online communities. k-plex analysis and hierarchical cluster-ing are used to identify and contrast subgroups, and the methodology is demonstrated in a case study involving the TorCamp Google group community. We assessed the validity of the subgroups obtained in the case study by comparing them with the members experienced, sense of community, and their self-reported acquaintenceships. Results suggest that active subgroups of people not only interact with each other at a higher rate, but also have a greater experienced sense of community. It is concluded that detection of active subgroups in online communities can be implemented widely using automated tools for analyzing the social networks implied by online interactions.

Using Web 2.0 to Locate Expertise
Sandra Jean “Sacha” Chua, University of Toronto
Finding experts who can help solve a problem can be difficult and time-consuming. Manually-maintained expertise profiles are often out of date. Expertise recommendations based on private data such as e-mail are difficult to verify. Intranet social computing services such as web logs (blogs), social bookmarking, and people-tagging can aid in building implicit profiles for expertise search using data captured in informal knowledge management tools. This paper introduces a meta-search tool that searches for experts based on their blogs, bookmarks, and tags. Results are visualized according to recency, organization, and geographic location. A usability study showed that users are highly satisfied with the tool, and are significantly more satisfied with the tool than with their existing techniques for finding experts.

A Trust Based Approach for Protecting User Data in Social Networks
Bader Ali, Wilfred Villegas and Muthucumaru Maheswaran, McGill University.
Automatic document classification is an important step in organizing and mining documents. Information in documents is often conveyed using both text and images, which complement each other. Typically, only the text content forms the basis for features that are used in document classification. In this paper, we explore the use of information from figure images to assist in this task. We explore image clustering as a basis for constructing visual words for representing documents. Once such visual words are formed, the standard bag-of-words representation along with commonly used classifiers, such as the naïve Bayes, can be used to classify a document. We report here results from classifying biomedical documents that were previously used in the TREC Genomics track based on the image-based representation. Efforts are ongoing to improve image-based classification and analyze the relationships between text and images.

Frontiers of Software Practice Plenary Session
Wednesday, October 24, 2007, 5:00 p.m. Topic: Didn't Samuel Solve That Game?
Dr. Jonathan Schaeffer, Department of Computing Science, University of Alberta
Jonathan Schaeffer is Canada's leading researcher and world leader in research on artificial intelligence (AI) applied to games. In 1986 his Phoenix program tied for 1st place in the World Computer Chess Championship. Chinook in 1990 was the first program to earn the right to play for the human World Checkers Championship, earning a place in the Guinness Book of World Records as the first program to win a human world championship in a non-trivial game of skill. Jonathan has been a key leader in the development of high speed and parallel computing in Canada. His next feat will be to solve poker! Abstract: In 1963, Arthur Samuel's checkers-playing program defeated a human opponent in a single game, a milestone for the fledgling field of artificial intelligence. Since that historic encounter, checkers has been branded as a "solved" game. This result was an aberration. In 1989 the Chinook project began with the goal of winning the World Checkers Championship. Along the way, there was an imposing obstacle to overcome: the unbeatable human World Champion, Dr. Marion Tinsley. And thus begins our story...
Although initially started as a research project, the Chinook effort soon changed directions and became a quest to defeat Tinsley. Instead of an impersonal contest between a man and a machine, it became a personal battle between two humans striving for supremacy at checkers. In this talk, the creator of Chinook presents the personal and technical sides of his 18-year obsession to win the World Championship and to ultimately solve the game.

In this presentation we take a look at how General Motors is utilizing and driving innovation in Software Engineering to meet the challenges of the vehicle domain.
Frontiers of Software Practice Plenary Session
Thursday, October 25, 2007, 12:00 p.m. Topic: Model-Driven Development of High Assurance Adaptive Systems
Dr. Betty Cheng, Computer Science and Engineering, Michigan State University
Betty Cheng is a Professor of Computer Science and Engineering at Michigan State University. Her research and teaching interests include formal methods for software engineering, component-based software development, object-oriented analysis and design, embedded systems development, dynamically-adaptive systems, visualization, and distributed computing. She was awarded a Faculty Fellowship from the California Institute of Technology and the NASA Jet Propulsion Laboratory in 1993 to apply newly developed requirements analysis and design techniques to a portion of the Shuttle software. In 1998, she spent her sabbatical working with the Motorola Software Labs investigating automated analysis techniques of specifications of telecommunication systems.
Abstract:
Increasingly, software should dynamically adapt its behavior at run-time in response to changing conditions in the supporting computing and communication infrastructure, and in the surrounding physical environment. In order for an adaptive program to be trusted, it is important to have mechanisms to ensure that the program functions correctly during and after adaptations. Adaptive programs are generally more difficult to specify, verify, and validate due to their high complexity. Particularly, when involving multi-threaded adaptations, the program behavior is the result of the collaborative behavior of multiple threads and software components.
This presentation overviews recent work that addresses assurance of adaptive systems at different points throughout the development process. The talk will cover techniques ranging from those to be applied as part of requirements engineering to those that are applied at run- time. An emphasis will be on those techniques that are automated and involve formal analysis of assurance properties. We will briefly describe new work into the use of digital evolution for the automatic generation of models of adaptive systems. Finally, we will highlight some of the key challenges for the research community in addressing assurance for current and future adaptive systems.

The streams of the events from these resources are captured. This information is used for CASCON 1998 monitoring resources' activities and diagnosing any error that may arise. We provide a workflow management service allowing users to orchestrate services based on the description of the resources, their dependencies and the captured streams to perform certain tasks. We also propose a combination of Web services and peer to peer technologies to support users in different communities and different network layers, and to decentralize resource management. Eucalyptus was demonstrated to be effective in assisting architects across multiple sites to effectively participate in a shared design session.

Automated Conversion of Table-based Websites to Structured Stylesheets Using Table Recognition and Clone Detection
Andy Mao, James R.Cordy and Thomas R. Dean, Queen's University. Web standards such as XHTML and CSS are rapidly coming into practice and have many advantages, including compatibility, consistency across browsers, and increased ease of maintenance. Unfortunately large numbers of existing websites still use the deprecated table- based layout style in which page style is unique to each page. Existing tools for automating the transition to stylesheets provide little help, converting page-by-page using a flattened structure and local inline styles rather than a common CSS stylesheet. In this work we present an automated method for converting table-based layout websites to standards-compliant modern CSS stylesheet-based websites using a two-step process.
back to list A Search-Based Approach for Dynamically Re-packaging Downloadable Applications Thierry Bodhuin, Massimiliano Di Penta and Luigi Troiano, University of Sannio. Mechanisms such as Java Web Start enable on-the-fly downloading and execution of applications installed on remote servers, without the need for having them installed on the local machine. The rapid diffusion of mobile devices (e.g., PDAs) connected to the Internet make these applications appealing to mobile users. However, in many cases the available bandwidth is limited, and its excessive usage can be expensive. This paper proposes an approach based on Genetic Algorithm and an environment that re-packages it with the objective of limiting amount of resources transmitted for using a set of application features. The paper reports an empirical study on the application of the proposed approach on three medium-size Java applications.

Session: Event Monitoring
Runtime Monitoring of Web Service Conversations BEST STUDENT PAPER Yuan Gan, Marsha Chechik and Shiva Nejati, University of Toronto; Jon Bennett, Bill O'Farrell and Julie Waterhouse, IBM Toronto Lab. For a system of distributed processes, correctness can be ensured by (statically) checking whether their composition satisfies properties of interest. In contrast, web services are being designed so that each partner discovers properties of others dynamically, through a published interface. Since the overall system may not be available statically and since each business process is supposed to be relatively simple, we propose to use runtime monitoring of conversations between partners as means of checking behavioural correctness of the entire web service system. We describe an implementation of our approach as part of an industrial system and report on preliminary experience.
back to list Pattern Rewriting for Efficient Search in Partial-Order Event Data Matthew J. Nichols and David Taylor, University of Waterloo. When working with large sets of partial-order event data, typically collected from the execution of a distributed application, it is often desirable to search for specific patterns of events within this data. Such pattern matching must account for attributes on individual events as well as relationships between events and sets of events. In this paper, we propose a method for transforming complex hierarchical patterns into simpler, flattened patterns. This new way of expressing patterns eliminates the need for a costly convex-closure operation at each step in the search process. It also facilitates further optimizations such as re-ordering of pattern elements.

MARO - MinDrift Affinity Routing for Resource Management in Heterogeneous Computing Systems Yu-Tong He, Issam Al-Azzoni and Douglas Down, McMaster University.
This paper deals with designing effective resource management strategies for systems of heterogeneous computers. We consider a system with I types of independent Poisson task demand arrival streams and J parallel servers with independent non-identical service time distributions for each arrival type. The decision of routing each type i task immediately upon arrival to a server is made by comparing the state information of a subset of the J servers. We show that choosing the subset according to a linear programming (LP) problem which maximizes the system capacity can not only significantly reduce the amount of state information required in making the routing decision, but also yield shorter total mean queue compared with the policies requiring global state information.

Session: Computer Supported Collaborative Work and Human Computer Interaction
Out of Sight but Not Out of Mind? Informal Networks, Communication and Media use in Global Software Teams Klarissa T. Chang, Carnegie Mellon University; Kate Ehrlich, IBM Research. In an effort to reduce costs and improve staffing options, companies are going offshore to staff software projects. Although advances in communication technologies make it easier to share information, a growing number of studies have highlighted the disadvantages and hidden costs of distributed teams. This paper reports the results of a study that used social network analysis to study the informal communication patterns in three successful global software teams. The results indicated that technical leaders acted as brokers to coordinate work across tasks and sites in self-organizing sub-groups. Personal networks, awareness of tasks and accessibility influenced communication which in turn affected the social climate of the team. We discuss the implications of these results for technologies that support awareness and for management practices, especially in globally distributed work contexts.
back to list Using Paper Mockups for Evaluating Soft Keyboard Layouts I. Scott MacKenzie, York University; Janet C. Read, University of Central Lancashire. Five experiments were conducted to compare soft keyboard layouts. The methodology involved paper mockups and manual timing in a classroom situation. Students worked in pairs -- one as experimenter, one as participant -- swapping roles midway through the experiment. Participants used a stylus to tap the well-known "quick brown fox" phrase five times on the different layouts. Entry speeds, computed from the measured time to entry the phrase, were varied for the Qwerty keyboard layout, the Opti layout, the Fitaly layout, for a Qwerty-Phone (QP) hybrid layout, and for the standard phone keypad layout. The merits and limitations of the evaluation method are discussed.
back to list Improving Predictive Models of Cognitive Complexity Using an Evolutionary Computational Approach — A Case Study Rodrigo Vivanco, University of Manitoba and National Research Council Canada; Dean Jin, University of Manitoba. The development of software is a human endeavor and program comprehension is an important factor in software maintenance. Predictive models can be used to identify software components as potential problems for the purpose of future maintenance. Source code metrics can be used as input features to classifiers, however, there exists a large number of structural measures that capture different aspects of coupling, cohesion, inheritance, complexity and size. This paper presents initial results when using a genetic algorithm as a method of improving a classifier's ability to discover cognitively complex classes that degrade program understanding. back to list Back to top
Wednesday, October 24 paper presentations Session: Autonomic Computing
A Real-Time Adaptive Control of Autonomic Computing Environments Bogdan Solomon and Dan Ionescu, University of Ottawa; Marin Litoiu and Mircea Mihaescu, IBM Toronto Lab. Many techniques have been proposed to monitor, analyze, and change a system under observation, but less attention has been paid to adapting the autonomic computing loop itself. Based on previous results on the design and implementation of a reference real-time architecture for autonomic computing, a self-adapting loop based on system-specific adaptation knowledge is proposed. The proposed system is an integral part of the real-time system which controls the behavior of the computing environment evaluating its global behavior using criteria which take into account the mathematical description of the time variation of the number of users in the system.
back to list Policy-driven Autonomic Management of Multi-component Systems Raphael M. Bahati, Michael A. Bauer and Elvis M. Vieira, The University of Western Ontario. Policies have been proposed as a means to express required or desired behavior of systems and applications, and possible management actions for resolving violations, to an autonomic manager. In multi-component systems, such as e-commerce systems, independent sets of policies often deals with managing the behavior of the individual components. In turn, the autonomic management system uses the policies to make decisions on what actions to take per component when a policy is violated. During operation of these multi-component systems, however, these independent sets of policies may yield multiple directives from which the autonomic manager must select one or more appropriate actions. In this work we look at heuristics that an autonomic manager might use to select an action. We outline the design and implementation of an autonomic manager making use of these heuristics and describe our experiences with it in a dynamic Web server. Experimental results are reported comparing the effectiveness of the heuristics.

A Comparative Study of Pairwise Regression Techniques for Problem Determination
Mohammad A. Munawar and Paul A. S. Ward, University of Waterloo. Many runtime metrics can be collected from modern software systems. Stable statistical relationships exist among these metrics. Deviation from these stable relationships indicates potential problems, allowing diagnosis of faulty components. There exist many modeling techniques to represent these relationships. However, which one to use is a question that has yet to be studied.
In this paper we compare the use of simple linear regression (SLR) to some of its more complex variants, including autoregressive regression with exogenous input (ARX ) and locally weighted regression (LWR). We consider the component coverage, model robustness, accuracy of diagnosis, and computation cost in our comparison. Our study finds that while models with time-lagged variable can improve diagnosis accuracy, they achieve it at the cost of reduced robustness. In particular, we found the autoregressive regression model with exogenous input (ARX) to provide the most accurate diagnosis; however, it is the least robust of the techniques considered and the second most expensive. This study also finds that smoothing and other data transformations can noticeably improve results of SLR, thus providing an efficient alternative to ARX. Nevertheless, autoregressive models provide additional information on the state of the system and such information should not be ignored. There is a need to find ways to leverage these models knowing their vulnerability to false alarms.

Client Certificate and IP Address Based Multi-factor Authentication for J2EE Web Applications Heesun Park and Stan Redford, SAS Institute Inc Secure and encrypted authentication is an important aspect of J2EE web application security. SSL client certificate authentication provides password-less, encrypted login mechanism and single sign on capability. Unlike SPNEGO protocol based Kerberos authentication, which requires both parties in the same domain, client certificate authentication works across the domain boundary as long as the user registry for application server is properly set up to handle the certificate. But there are shortcomings. We will examine the potential vulnerability of the client certificate authentication and will show how to make it more secure by adding IP address checking servlet filter for the web application.. back to list An Audit Trail Service to Enhance Privacy Compliance in Federated Identity Management Liam Peyton, Chintan Doshi and Pierre Seguin, University of Ottawa.
Federated identity management systems, such as the Liberty Alliance framework, are intended to protect identity and control access to personal information. An audit trail service has been proposed as an addition to the framework to address potential privacy breaches. A simple scenario is used to analyze what should be logged to an audit trail and how it should be logged in order to address privacy concerns and comply with privacy legislation. The implementation of an audit trail service conforming to the Liberty Alliance data service template is described in this research.
back to list Window Query Processing for Joining Data Streams with Relations BEST PAPER Kristine Towne and Qiang Zhu, The University of Michigan - Dearborn; Calisto Zuzarte, IBM Toronto Laboratory; Wen-Chi Hou, Southern Illinois University.
Query processing for data streams raises challenges that cannot be directly handled by existing database management systems (DBMS). Most related work in the literature mainly focuses on developing techniques for a dedicated data stream management system (DSMS). These systems typically either do not permit joining data streams with conventional relations or simply convert relations to streams before joining. In this paper, we present techniques to process queries that join data streams with relations, without treating relations as special streams. We focus on a typical type of such queries, called star streaming joins.

The Scalability of AspectJ Arjun Singh and Gregor Kiczales, University of British Columbia.
To assess the scalability of AspectJ, we refactored concerns that crosscut over half of the plug- ins that comprise the Eclipse IDE. We evaluated our AO refactored system quantitatively by examining changes in execution time and memory usage, as well as qualitatively by examining changes in scattering, coupling, and abstractions. The conclusion was that AspectJ scales well in that it can be used in large systems, but that the system may require modifications to the build and class loading procedures in order to cope with defining advice that cross system boundaries.
back to list Threats on Building Models from CVS and Bugzilla repositories: the Mozilla Case Study Kamel Ayari, Peyman Meshkinfam and Giuliano Antoniol, École Polytechnique de Montréal; Massimiliano Di Penta, University of Sannio Information obtained by merging data extracted from problem reporting systems—such as Bugzilla—and versioning systems—such as Concurrent Version Systems (CVS)—is widely used in quality assessment approaches. Quality assessment approaches based on software repository data usually rely on two underpinning assumptions. According to the first assumption, relationships and in specific the traceability links between facts documented in the two repositories can be established with high reliability. Secondly, issues posted on problem reporting systems are related on defect correction. This paper attempts to shed some light on the validity of these two assumptions while trying to integrate information extracted from Mozilla repositories.

Comparing Episodic and Semantic Interfaces for Task Boundary Identification
Izzet Safer and Gail C. Murphy, University of British Columbia
Multi-tasking is a common activity for computer users. Recent approaches to help support a user in multi-tasking require the user to indicate the start end points of tasks manually. Although there has been some work aimed at inferring the boundaries of a user's tasks, it is not yet robust enough to replace the manual approach. Unfortunately, with the manual approach, a user can sometimes forget to identify a task boundary, leading to erroneous information being associated with a task or appropriate information being missed. These problems degrade the effectiveness of the multi-tasking support. In this paper, we describe two interfaces we designed to support task boundary identification. back to list Back to top

Title: Optimization of Queries for Business Intelligence Principal investigator: Jarek Gryz Project participants: Name Affiliation: [email protected] York University Parke Godfrey IBMer Jaroslaw Szlichta York University York University
Proposal Abstract: Performance of queries for business intelligence has always been a challenge. Not only is the amount of data in a data warehouse large, the queries themselves are complex and ad-hoc. The problem of query complexity has recently been compounded by the introduction of query managers/builders. Current commercial query optimizers have been designed at the time when virtually all database queries were written by IT professionals. This assumption determined to a large degree the types of queries that could be optimized well. Queries generated automatically can be quite different from queries written by humans. In this project we plan to analyze and optimize such automatically generated queries. We will also look into improving schema design in a data warehouse for better query performance.

Title: Parallel Methods for Real-Time OLAP on Multi-Core Processors and Cloud Architectures Principal investigator: Prof. Frank Dehne Project participants: Name Affiliation: Prof. Frank Dehne Carleton University [email protected] IBMer Hamidreza Zaboli Carleton University David Kwan Robin Grosset David Allatt IBM Employee David Cushing IBM Employee Charles Potter IBM Employee IBM Employee
Proposal Abstract: Online Analytical Processing (OLAP) is a core component of business intelligence software from IBM Cognos. OLAP is used for business sales reporting, marketing, management reporting, business process management, budgeting, forecasting, and financial reporting. At the core of OLAP is the Data Cube, a multi-dimensional data structure created from a star schema or snowflake schema of tables in a relational database. The Data Cube provides an efficient implementation of the core OLAP queries: roll-up, drill-down, slice and dice. With ever increasing corporate data volumes, performance issues have become a bottleneck for OLAP users. Another important trend is the need for real-time OLAP which allows business intelligence applications to query more up-to-date business data. This requires frequent and fast updates of the Data Cube which can cause performance problems. The main current driver for processor innovation and performance improvement is the use of multi-core processors and cloud-based distributed architectures. Both these scenarios require parallel, multi threaded software to make use of these performance gains. The investigator has many years of experience in parallelizing data cube construction and querying for processor clusters [1-7] and cloud-based distributed architectures [8]. We will utilize this experience to study the following: 1. Parallel OLAP and Data Cube build and query optimization for multi-core processors and cloud architectures 2. Efficient real-time OLAP and incremental Data Cube updates on multi-core processors and cloud architectures. The project will include both, theoretical research on new parallel algorithms for OLAP on multi-core processors and massively distributed cloud architectures, and applied research including proof-of-concept prototypes to evaluate the performance of our algorithms on real data sets and query scenarios. The goal of the project is to utilize the computational power of multi-core processors and the increasing number of cores per processor for high performance real-time OLAP and Data Cube systems, as well as the application of these algorithms to massively distributed cloud architectures. Such methods will enable business intelligence software from IBM Cognos to efficiently handle larger and more up-to-date data sets.

Proposal Abstract: A scalable and user-friendly business intelligence system for processing ever-increasing data is vital for maintaining competitiveness. The enhancement based on Hadoop can be a timely and feasible solution. We propose to use Hadoop as a cache for Online Analytical Processing (OLAP) to store relational data, annotations, other information and retrieve it in a user-friendly way with the scalable performance. In addition, we will exploit multi-core computing, including GPU, to accelerate this Hadoop-based OLAP system.

Title: Comparing and Complementing Relational Database Engines with Map/Reduce-Style Processing Techniques Principal investigator: Volker Markl Project participants: Name Affiliation: [email protected] TU Berlin Berni Schiefer IBMer Stefan Ewen IBM SWG Alexander Alexandrov TU Berlin TU Berlin
Proposal Abstract: In the context of its global Smarter Planet initiative, IBM is promoting ways to leverage Information Technology to improve the quality of life on our planet. There are many examples how IT, and specifically data intensive analysis, can be used to make the planet smarter: One example is in climate simulations that make predictions on how to set up agricultural economies, like big parts of the monsoon dependent Indian agriculture. Another one is traffic analysis, where the optimization of traffic flow in large cities helps to effectively reduce the inner-city traffic congestion, increasing living quality and lowering carbon-dioxide exhaust. Problems like these require massive parallel processing, since otherwise an analysis cannot be performed in reasonable time.
While such analysis was traditionally done using parallel databases, current trends are now gaining momentum. Map/Reduce systems are currently a major challenger for the well established parallel databases. The discussion about the future of that technology is still boiling. Proponents argue that for certain data-processing tasks, Map/Reduce jobs can be scaled flexible up to very large number of computers. They cite the simplicity of the programming model, the scalability, the fault tolerance, and the ability to parallelize a variety of tasks beyond relational queries as the main advantages of Map/Reduce systems compared to parallel databases [4, 5]. Opponents criticize the technology as immature and unsuitable for complex relational queries. For many tasks, traditional Database Management Systems still outperform Map/Reduce Systems [1].
Without a doubt, both systems have their sweet spots. In the scope of this CAS project, we want to investigate how traditional relational database systems can profit from new paradigms like Map/Reduce. Since a benchmark that assesses the systems in a complex business environment rather than on top of simple individual queries is still missing, we are currently working on a new comprehensive benchmark aiming to fill this gap. The benchmark is based on a decision support warehouse from web retailer augmented with some new aspects like community generated contents, fraud detection and analysis of non-relational data. It should serve as foundation for a thorough comparative analysis of different architectural paradigms for parallel data processing that should provide us with the much-needed deeper insight of the sweet and weak points of the different architectures.
We intend to use this knowledge in order to improve the specification and execution of database programs that are currently a sweet spot of Map/Reduce systems. Based on the findings from the first phase of the project, we plan to build a proof of concept that augments a database engine like DB2 with concepts from a massively parallel execution framework like Hadoop [3]. We will install that proof of concept on a compute cluster and evaluate the performance of the hybrid approach in comparison to other competing parallel data processing engines.

Title: XML Query Delegation on the Cloud Principal investigator: Mariano Consens Project participants: Name Affiliation: [email protected] U. of Toronto Neil Graham IBMer Jerome Simeon IBM Toronto Shahan Khatchadourian IBM Watson U. of Toronto
Proposal Abstract: The project aims to develop techniques for the formulation, analysis and evaluation of XML (and other web data) query processing tasks to exploit parallel data processing in cloud environments (the dominant Hadoop platform, in particular).
Our work will address the challenge of extending an XQuery processor to take advantage of cloud data platforms and techniques. First, we will develop additional XQuery language extensions (as well as leveraging related extensions such as records, updates, higher order functions), and the related infrastructure, to support the delegation within the Hadoop framework of query processing tasks. The map-reduce tasks described by an XQuery expression are also implemented by instantiating multiple XQuery processors, taking advantage of XML data stored in the cloud, in HDFS and other suitable SQL and non-SQL stores.

Title: Autonomic Problem Determination of Enterprise Software Systems Principal investigator: Paul Ward Project participants: Name Affiliation: [email protected] University of Waterloo Thomas Reidemeister IBMer Miao Jiang University of Waterloo Masoomeh Radufshani University of Waterloo Yi Luo University of Waterloo Charles Lai University of Waterloo Andrew Trossman University of Waterloo IBM Employee
Proposal Abstract: Success for many businesses depends on their software systems. These systems have high-availability requirements. This project focuses on problem determination in enterprise software systems, with the goal of quickly detecting failures and pinpointing faulty components. The project aims to address the following:
Problem detection and diagnosis using behavioural models created from observed monitoring data (log data, other event data, management metrics, etc.) Integration of analysis of monitoring data for robust problem determination Adaptive collection of monitoring data to reduce overhead and performance impact Scaling monitoring to large systems Making behavioural models adaptive to changes in the system and its environment
In our previous project we developed prototypes to analyze management metrics and log records to perform problem detection and elementary root-cause analysis. We evaluated this prototype around a simple e-commerce infrastructure that consists of a workload generator (Rational Performance Tester, RPT), a WebSphere Application Server, and a DB2 database system. We collected Java Management eXtensions (JMX) data and log records from the various components. Analysis of the JMX data was performed by our custom-written monitoring engine which builds a behavioural model of the JMX data. It emits Common Base Events (CBEs) whenever there is a statistically significant deviation in the behaviour of the system from that predicted by the model. Log record analysis is performed within Log and Trace Analyzer (LTA) using a mixture of hand-coded symptoms and statistical analysis. The hand-coded symptoms are created based on analysis of log records generated during fault-injection experiments on our prototype testbed. The statistical analysis approach is performed by our LTA plug-in. It is based on building a behavioural model of the log records; deviation from this model causes the plug-in to emit a CBE indicating the problem. Those log records that are identified by the behavioural model as being responsible for the deviation are identified and highlighted within the Log Analysis View of LTA. The method for achieving this is the subject of a patent draft.
While we have, therefore, made excellent progress on log and metric analysis for problem determination, there are still a very large number of open problems. For the proposed three-year project we want to address the following issues:
Improved system coverage by combining the log-data analysis with the continuous-data analysis Integration of our monitoring engine into existing IBM tooling (especially IBM Tivoli Monitoring, ITM) Automated robust-symptom generation based on statistically significant symptoms identified by the behavioural models Improved robustness of behavioural model for log-data and other event-data analysis Extending the range of faults that can be detected and diagnosed Improving the quality of detection and diagnosis; reducing the false positive and false negative rates to ensure use within a support environment Symptom-definition action for problem validation (test-suite to validate fault hypothesis)
The main focus for the first year will be:
ITM integration of JMX approach Extending the range of faults that can be detected and diagnosed Automated symptom generation based on behavioural model of log data
All research results will be validated through prototypes generated using IBM tools, with the intent that the prototypes can be integrated back into IBM tooling. Our hope and expectation is that we will have significant impact on IBM problem determination tooling and support. It is for this reason that our proposed collaborators within IBM include both development staff and technical support staff.

Title: Management Sevices for Cloud Computing Principal investigator: Marin Litoiu Project participants: Name Affiliation: [email protected] York University Hamoun Ghanbari IBMer York University
Proposal Abstract: Cloud computing is a new deployment and operational model in which high level computation services and storage are provided by the Internet ("cloud"). In this project, we investigate a multi-layered general purpose cloud computing model. In the first layer, different clouds offer basic hardware functions such as storage and raw computation; in the second layer, a service layer offer higher level computational services that provision and manage upper layer resources (i.e. containers for PaaS, multi-user software for SaaS or virtual desktop instances for DaaS). The project will address the challenges in federating clouds in different environments (PaaS, SaaS, DaaS): the brokerage of resources, the cost model and the scalability of the federation. A broker will assess the instance resource needs, the cost model and, by employing analytical models-such as queuing and regression predictive models- will select and negotiate the most cost and performance efficient resources to store and run the instance.

Title: Open Architecture for Adaptive Autonomic Computing Platforms with Applications to On- the-Cloud Services Principal investigator: Dan Ionescu Project participants: Name Affiliation: [email protected] University of Ottawa Bogdan Solomon IBMer Stejarel Claudiu Veres University of Ottawa Cristian Gadea University of Ottawa University of Ottawa
Proposal Abstract: Cloud Computing has been considered lately not only as the panacea to all problems service designers, providers and users had so far, rather the solution of reducing power consumption of the IT infrastructure globally, and locally at the enterprise level. There are so many angles that cloud-computing the marketer present that it is difficult to properly understand what is reality and what is a feature to come, under the today market pressure. Definitely, offering a Service on-the-cloud raises more problems than solutions are to it. Autonomic computing, on the other side, is a technology still under development but has a big potential to solve a series of the pending issues of offering on- the-cloud services. It is clear now, that the on-the-cloud has stringent requirements on designing the application server such that it can automatically discover its peers and, as in a federated system, to connect the client to the best server candidate. This is a self-optimization system. In this phase of the project we propose to use adaptive and self-organizing autonomic computing strategies for the Autonomic Computing decision making module and to explore the possibility of applying our real-time control architecture to the optimization of resources in an on-the-cloud service. From a methodology point of view the research, design, and implementation of the prototype, we will rely on an application developed by the applicant’s research team and on deploying it on the existing facilities of the Network Computing and Control Technologies Research Laboratory directed by the applicant. From the same point of view we aim at deploying it at least at York University Research Lab deirected by Prof. Marin Litoiu. This will make the application distributed on-the-cloud. The application is a web collaborative platform which allows an arbitrary number of users to participate in a session for viewing and interacting with videos, pictures, document files, real-time video streams, and GIS maps sensor data.displaying in real-time. The server is deployed on a virtualization layer span all over the on-the-cloud locations and computers. The project will study, design and implement an autonomic computing infrastructure which is a development an extension of the existing Autonomic Computing solution developed and implemented in previous phases of this project. The research will focus on the decision making module to endow it with algorithms specific to self-organizing systems. This is a new and hot area of research which potentially will lead to new concepts in Autonomic Computing, while the application of the Autonomic Computing to on-the-cloud services has the potential to offer a solution for unsolved problems like the optimization of the resources used in a cloud computing environment, self-provisioning of on-the-cloud services and others.

Title: Distributed Crawling and Security Assessment of Rich Internet Applications Principal investigator: Gregor v. Bochmann Project participants: Name Affiliation: Gregor v. Bochmann University of Ottawa [email protected] IBMer Guy-Vincent Jourdan University of Ottawa Khaled Ben Hafaiedh University of Ottawa Seyed M. Mir Taheri University of Ottawa
Proposal Abstract: The security of Web applications is an important issue for protecting sensitive company, customer, and employee data, for meeting regulatory and corporate compliance requirements, and for defending against the high cost of a data breach. In the case of Rich Internet Applications there are additional challenges because the Web pages executed at the client side may contain powerful program fragments that may execute without being visible by the user. In an ongoing research project, we have developed methods and tools for crawling Rich Internet Applications in order to build a model of these applications that helps for testing the application for security, accessibility and other issues.
The objective of this research project is to explore the possibility of increasing the speed of these crawling algorithms by performing concurrent crawls, that is, executing several crawling programs concurrently on different computers. We note that a web application scan, using current technology, may take several weeks for complex applications. On the other hand, many large organizations have access to easily provisioned throw-away on-demand computing resources. We envision to use concurrent execution platforms, such as cloud computing and/or peer-to-peer networks, for the crawling of RIAs. We plan to explore different concurrent architectures and different distributed algorithms for controlling the concurrent crawling activities. The main research issues are expected to be related to the way the crawling of different parts of the application will be distributed to the different crawling engines and how these engines communicate with one another in order to exchange the necessary information to coordinate their work and to avoid duplication and overloading of the infrastructure.
We will also consider the use of a network of parallel crawling engines for purposes for which a single crawling engine is not sufficient, as for instance, testing an application under high load, e.g. a simulated distributed denial of service attack, or finding vulnerabilities based on race conditions. During the later part of the project, we plan also to study how white-box analysis can benefit from a cloud computing architecture, and how the distributed black-box crawling approach can be combined with white-box analysis of the application program in order to obtain a more complete model of the application.

Title: Virtual Machine Management for Efficient Configuration and Performance Optimization in Cloud Computing Principal investigator: Cristiana Amza Project participants: Name Affiliation: Cristiana Amza University of Toronto [email protected] IBMer Saeed Ghanbari University of Toronto Madalin Mihailescu University of Toronto
Proposal Abstract: Cloud environments are often present in organizations that provide dynamic content services, such as, e-commerce, on-line banking, stock trading. Such services generate content on-the-fly based on persistent state stored in databases. Resource virtualization is a promising technology for supporting performance isolation between different applications running in a shared cloud environment.
We propose to develop a runtime system that leverages network and application topologies discovered on the fly, as well as given availability constraints to implement Virtual Machine placement optimizations for applications onto the virtualized infrastructure. We will monitor network traffic among virtual machines, transparently, to discover application topologies. To enforce availability constraints, we will allow application owners to specify groups of highly available virtual machines. Based on this information, HAP builds on-line topology graphs for applications and automatically partitions these graphs to optimize network traffic between VM's while respecting availability constraints. We will then performs live virtual machine migrations according to the partitioned graph for each application.
We will evaluate our algorithms in a realistic cloud setting using a mix of realistic workloads, such as, Hadoop and IBM workloads. We expect our system to improves performance in cases of dynamically ocurring network bottlenecks or other configuration problems. By detecting network patterns on the fly, and performing appropriate virtual machine migrations, we expect to eliminate network interference, or other bottlenecks while maintaining application availability.

Breaking News CASCON 2011 Breaking News
Press Release IBM Software Aids Research Aimed at Extending Seniors’ Independent Living Click here for breaking news EDMONTON, Alberta and MARKHAM, Ontario, Nov. 8, 2011 -- [CASCON] -- IBM today announced its software is being used to from CASCON correlate data from sensors capturing patient activity and replicate that in a virtual world with avatars that represent the elderly subjects in a unique pilot aimed at providing health researchers and students with insights on how to care for Canada's aging CASCON facebook page population. Follow us on facebook Since June, 2011, University of Alberta researchers in collaboration with Edmonton's Glenrose Rehabilitation Hospital have been using IBM software to study elderly clients who volunteer to stay in a model, self-contained "independent living suite" at the facility. The suite is instrumented with sensors and equipped with smart devices collecting information about their daily activities. Friends of CASCON
The data will be used to understand how to make better use of healthcare resources, enable remote collaboration among providers, and contribute to early intervention and long-term management of chronic diseases. Researchers will also learn how to prepare older people for independent living, and extend the length of time seniors are able to live in their homes.

IBM WebSphere® Sensor Events software collects and processes a stream of data from sensors capturing a range of medical and physical inputs, from heart-rate and body weight to electricity consumption and the use of doors, furniture, light switches and appliances. The data stream is analyzed to assess the occupant's ability to take medication as prescribed and other aspects of independent living. The analysis results are also used to animate an avatar of the occupant that mirrors their activities in a virtual version of the apartment.
"We are using an avatar and the visualization to represent the people in the suite as this is far less intrusive than having a video or live monitoring system on them all the time," says Dr. Lili Liu, a professor of occupational therapy at the University of Alberta, and research affiliate at Glenrose Rehabilitation Hospital.
This virtual-world view can be monitored in real time, and replayed recordings can be used for simulation training for health- sciences students. Ultimately, researchers hope to understand how the integration of sensor networks with virtual worlds can impact the future of at-home health monitoring and care delivery.
While the pilot is still ongoing, researchers have identified a need to track two new activities - use of wheel chairs or walkers, and food intake. Additionally, by monitoring subjects' use of a medication reminder device, they have determined how to improve its usability.
"We know data is being generated all the time, but harnessing, aggregating, analyzing and gaining insights from it have been challenges. When you view data as diverse as heart rate monitor and electrical consumption independently, out of context, it means very little. The IBM software has enabled us to put it together in a visualization and actually see a patient's ability to function independently, so clinicians can intervene when necessary and students can learn how best to care for them. It has provided visibility to the physical world in a way we've never been able to see it before," says Eleni Stroulia, NSERC/AITF Industrial Research Chair on Service Systems Management at University of Alberta.
The research was released today at CASCON, an annual conference showcasing Canadian research IBM's Centres for Advanced Studies undertake in partnership with academic and government research organizations.
The pilot comprises the first 'real-world' trial, where the concept moved out of a university simulation environment to the Glenrose Rehabilitation Hospital, and is part of the "Smart Condo(TM)" initiative, a multi-year, research collaboration with the IBM Alberta Centre for Advanced Studies, professors and students from six faculties at the University of Alberta, as well as NSERC, OLSONET, AITF and the Government of Alberta.
"Innovation isn't just about new technologies and inventions, it is about taking what we have and getting the very most out of it," said the Honourable Greg Weadick, Minister of Advanced Education and Technology. "The Smart Condo is an outstanding example of how we can use innovative technology to help Albertans be safer, healthier and more connected, best of all, right in their own homes."
A permanent "Smart Condo" installation is currently being completed at the Health Sciences Education and Research Commons, part of the University of Alberta's new Edmonton Clinic Health Academy.

Extending CAS for Today’s Relevance IBM Canada Software Laboratories, Center for Advanced Studies, Toronto
Joanna Ng, Program Director of CAS and IBM Master Inventor, IBM Canada Software Laboratories, Toronto
Abstract In 1990, IBM created the first Center for Advanced Studies (CAS) in Toronto, Canada. It was established to conduct collaborative applied research with researchers from academic organizations, IBM researchers, IBM software developers and technical leaders. Fruitful research results are being transferred into strategic IBM products. To carry out this mission, the CAS leadership team developed a set of principles to guide the organization's research operations. This model has proven successful in enabling the publication of many academic papers, the filing of patents and implementation of prototypes, creating a positive business impact for IBM software products. The success of CAS Toronto is also manifested in its long-term relationships with academic partners and their students. As a result, twenty two CAS sites were formed around the world. While the CAS research model has remained fairly stable over the years, IBM’s recent mandate of ‘Smarter Planet’ (the notion of transforming business and technologies to enable the world’s infrastructure to become increasingly instrumented, interconnected and intelligent, as almost anything can become digitally aware) creates new research challenges. The magnitude of research scope and complexity regarding computing needed to enable such large-scale instrumentation, interconnectivity and intelligence is huge. It requires well thought out research integration across various disciplines of science. This white paper introduces the extension of the current CAS research model to: (1) foster interdisciplinary and synergistic research; (2) accelerate validation, amalgamation and bootstrapping research results to impact the strategy, architecture and implementation of IBM software products and services; (3) set up an integrative collaboration in research across various virtual organizations. The objective of this extension is to preserve CAS' proven success in research areas critical to IBM business, while ensuring that applied research is green, pioneering and significant to related fields of science.

Author: Joanna W. Ng, IBM Canada Software Lab. IBM Canada Software Lab Center for Advanced Studies, Toronto “Extending CAS for Today’s Relevance” Page 3 of 13 Capturing the Rich CAS Heritage CAS Mission The Center for Advanced Studies (CAS) in Toronto was established in 1990. Its original mission was “to become a world-class applied research center that facilitates the transfer of advanced research into strategic products. The applied research to be done must be defined by the product groups within the Toronto laboratory.”1 CAS establishes its strength in technological advancement through conducting collaborative applied research significant to both academics and IBM business. Over time, the mission of CAS has proven highly valuable to both the academic partners with CAS and to IBM. As a result, twenty two CAS centers have been established at various IBM sites around the world in the past eighteen years. In 2008 alone, CAS Toronto published 24 academic papers and filed nine patent applications, all related to technology areas critical to IBM Software Group products.
CAS Principles A set of research principles was developed to guide CAS in fulfilling its mission.2 These key principles are: Principle #1: Win-Win Design Fruitful, trusted, and successful partnerships between academic researchers and IBM software development groups are gauged through diligently defining and maintaining the win-win relationship between both parties, recognizing that the measurement of success differs between each group. The “win-win design” principle focuses on research in areas that are academically important for CAS academic partners and critical to IBM business. This produces results that satisfy both groups – namely, academic publications, patent filings and prototype validations and IBM products that harvest these research results and gain the competitive edge.
Principle #2: IBM Mission Driven CAS Research All CAS research must be “directly related to the mission of the laboratory and… [completed] in the short to mid-range time frame.”3 This principle is pivotal for IBM in securing a return on its investment in CAS research. This has been expanded to apply to the general mission of the IBM Software Group world wide and also the global services organization. CAS faculty members benefit by gaining access to customer problems and acquiring rich customer data for their research.

Author: Joanna W. Ng, IBM Canada Software Lab. IBM Canada Software Lab Center for Advanced Studies, Toronto “Extending CAS for Today’s Relevance” Page 4 of 13 Principle #3: Collaboration Setup with Experts of Specific Research Field A critical aspect of the CAS research model is to nurture and foster a virtual team with the most established and relevant expertise in specific research areas. This team comes from within IBM (e.g. IBM researchers, customer-facing consultants, technical leaders and software developers from the IBM Software laboratories) and from academic partners (e.g. university researchers, customers, other vendors and government research institutions). The long-term relationships established over the years with talented CAS faculty members enable efficient and fruitful research collaboration.
Principle #4: Leveraged Funding IBM’s investment in CAS is leveraged to apply for additional funding sources that will compound the total resources for conducting research. The source of funding typically comes from external sources like federal and provincial government research institutions and internally from IBM corporate funding. Research cost efficiency and IBM's credibility in the industry make CAS an attractive research model for both IBM and faculty partners. This leveraged funding provides a financially optimal model for critical research, especially in light of the current tight economic reality.
CAS Research Program The current CAS Toronto Research Program at the IBM Canada Software Labs has the following key components which operate under the aforementioned principles: Centers for Advanced Studies Conference (CASCON) CASCON is a premiere computer science and software engineering academic conference where software developers and CAS research partners from academia, industry, and government collaborate by sharing knowledge and research results about the latest technological advancements. CASCON publications are published in the Association for Computing Machinery (ACM) Digital Library. Its average attendance is about 1,300 people. CAS Faculty Fellows CAS Faculty Fellows are academic partners who have a creditable history of successful research initiatives with IBM research and development over a period of time. Their work is well-recognized among their peers and aligned with CAS research priorities. Masters and Ph.D students who are supervised by CAS Faculty Fellows, referred to as CAS Students, often partner with IBM as well. Upon the successful completion of their graduate programs, many CAS Students go on to pursue successful careers at IBM. CAS Faculty Fellows have the privilege of accessing IBM facilities and online education resources. CAS also offers assistance in related patent filing and helps faculty and students foster long-term relationships with other IBM researchers and engineers. Faculty Awards CAS Faculty Awards are research awards granted to the selected CAS Faculty Fellows in order to enable collaborative research, typically over a period of one year, in areas of defined mutual interest and benefit. Research Fellowship Projects
Author: Joanna W. Ng, IBM Canada Software Lab. IBM Canada Software Lab Center for Advanced Studies, Toronto “Extending CAS for Today’s Relevance” Page 5 of 13 Research Fellowship Projects are CAS-sponsored graduate student projects supervised by CAS Faculty Fellows. These projects are conducted collaboratively with IBM and regularly reviewed by IBM business and technical stakeholders. Visiting Scientists CAS Visiting Scientists are distinguished CAS Faculty Fellows with a sustained history of outstanding contributions and success in various CAS research initiatives. They have demonstrated their long- term commitment to CAS and their research results have greatly impacted IBM business. Sabbaticals The sabbatical program offers distinguished CAS Faculty Fellows a place to conduct research in areas of mutual interest and benefits while on sabbatical leave from their academic institutions. University Day Workshops University Day Workshops are interim mini-conferences for CAS Faculty Fellows and IBM collaborators to meet and brainstorm new research agendas and innovative opportunities in the research fields significant to CAS and IBM. Being Relevant to Today’s Context The Global Context of IBM Very different from when CAS was first founded in Toronto eighteen years ago, IBM Toronto Laboratory has become a part of the IBM Canada Software Laboratories which is a part of the global organization of IBM Software Group. The original notion of local product mission in Toronto is replaced by the notion of product mission in the global context. Research Context IBM’s recent “Smarter Planet” initiative creates new research challenges in scope and complexity of various disciplines. A “Smarter Planet” is the notion that business and technology transformation will enable the world’s infrastructure to be increasingly instrumented, interconnected and intelligent, as almost anything can become digitally aware. Gartner called this “The Third Industrial Revolution of Digital Business in the cloud.”4 Gartner predicted that the top 10 contributing technologies for this revolution from 2008 – 2012 would be: multi-core and hybrid processors, virtualization and fabric computing, social networks and social software, cloud computing and cloud/Web platforms, web mash-ups, user interface, ubiquitous computing, contextual computing, augmented reality, semantics and social networks.5 Green and pioneering research areas will be defined by transforming these significant market trends into reality through the advancement of science. In order to ensure that CAS will continue to bring forth fruitful research results valuable to today’s IBM, extensions in CAS mission, research scope and collaboration are necessary.

CAS Mission
The original CAS mission has stood the test of time over the past eighteen years and is still relevant today. However, there are also necessary changes worth noting. CAS Toronto’s research scope has been expanded beyond the business interests of the laboratory locally at Toronto as it was first founded in 1990. As IBM Canada Software Laboratories have evolved to be a part of the IBM global organization, CAS Toronto’s research scope today has also been extended to include scopes that are of business interests of IBM software brand products world wide. In 2009, CAS Toronto expanded its research scope to cover the research requirements of IBM Global Business Services. The original CAS mission has been extended: to become a world-class applied research center that facilitates the transfer of advanced research into IBM strategic software products and services. The applied research must be validated by product groups within the world wide IBM Software Group or the IBM Global Business Services team.
Technology Incubation Lab (TIL) In addition to the well-established CAS Research Program, in August 2008, a software engineering unit was added to CAS Toronto – the Technology Incubation Laboratory (TIL). The mission of the TIL is to consume and integrate the research results from the CAS Research Program by applying software engineering necessary to build proof of concepts and proof of architecture of product enhancement or prototypes of new products. The purpose of TIL is to accelerate the transfer of advanced research into strategic products and services in a way that is consumable by the global IBM software development teams. TIL will also identify the missing science that inhibits real-world adoption of the research outcome and fill the gaps by enhancing future research agenda. TIL projects are initial prototypes and commercialization concepts of research results that IBM stakeholders can assess before deciding on their next level of investment.
CAS Research Staff Members
The original role of a CAS Research Staff Member (RSM) was to be staffed from “development groups [and] assigned to CAS for specific projects for a duration of six months to three years” 6 for the purpose of rapidly and effectively transferring applied research results to the development organization. 6 Therefore, CAS Research Staff Members were not originally viewed as permanent career.
6 J. Slonim, M.A. Bauer, P.A. Larson, J. Schwarz, C. Butler, E.B. Buss, and D. Sabbah, “The Centre for Advanced Studies: A Model for Applied Research and Development,” IBM System Journal 33, No. 3, 382-398 (1994)
Author: Joanna W. Ng, IBM Canada Software Lab. IBM Canada Software Lab Center for Advanced Studies, Toronto “Extending CAS for Today’s Relevance” Page 7 of 13
Going forward, as CAS expands in its mission, scope and collaboration network, it is important for CAS to be staffed with RSMs who have built and nurtured long-term relationships with IBM internal research as well as with CAS Faculty Fellows.
Research and technical skills critical to RSMs’ effectiveness also take time to develop. The RSMs’ depth and breadth of knowledge of the assigned research scope are also critical. The role of an RSM has gradually evolved into a permanent technical career in itself.
Integrative Research
In order to make progress in science despite of the challenge in magnitude and complexity of research relating to the computing for IBM’s initiative of the ‘Smarter Planet’, multiple CAS research projects of close research scope proximity are being grouped together in order to facilitate the sharing of research results; identifying opportunities for integration with other possibly related research projects in the hope of solving problems of larger scope that each individual project alone is not sufficient to solve. In order to facilitate such integrative collaborations, eight broader research themes are being called out. They reflect the business priorities of IBM as reflected in IBM’s Global Technology Outlook report as well as IBM Software Group general direction. These eight research focus areas are namely: • Smart Interactions • SOA 2.0 & Smart Services • Cloud Computing • Business Intelligence • Next Generation Systems • Software Development Processes • Software Development Tools • Database Technologies Detailed descriptions of these research initiatives are included in the appendix of this document.
Collaborate, Integrate, Innovate
In the spirit of integrative collaborations, researchers are encouraged to share results from their projects with other researchers on a regular basis. At the same time, researchers can be made aware of the other research projects and how these other projects relate and even help their own research. To enable this new level of demand for research collaboration, CAS Toronto has tagged its 50-plus projects under the research taxonomy of the eight CAS initiatives. Relationships between research sub-topics can also be
Author: Joanna W. Ng, IBM Canada Software Lab. IBM Canada Software Lab Center for Advanced Studies, Toronto “Extending CAS for Today’s Relevance” Page 8 of 13 defined. Such tagging and relationship association of CAS research projects enables related research groups to find each other within CAS as well as outside of CAS. In addition, CAS Meeting of Minds work groups that focus on major research initiatives were formed to foster the purposeful brainstorming and integration in order to solve more complex problems. These work groups are made up of CAS Faculty Fellows, CAS Visiting Scientists and IBM technical leaders of related fields. They get together to formulate a research agenda within the related technology area, identify related research problems, and propose a vision and strategy for related areas, possibly through position papers or white papers.
Summary and Conclusion Since the IBM Center for Advanced Studies (CAS) was first established in 1990 at the IBM Toronto Software Laboratory, it has played a significant role in bringing together IBM researchers and technical leaders with academic and government research organizations in order to conduct applied research. The operations model and missions of CAS Toronto have proven to be successful. Embracing challenges and changes over the years, the CAS principles of win-win design, IBM mission-driven initiatives and a research collaboration model have been extended to ensure that CAS research remains relevant in today’s global context of the business and the research need of the latest IBM initiative in computing for the ‘Smarter Planet. The CAS principle of leveraged funding makes the CAS research model financially efficient and attractive. This white paper highlighted how CAS Toronto’s research scope and agenda has evolved, how CAS Toronto as an organization has been extended in order to bridge between research and engineering to accelerate business impact. It also points out how the role of Research Staff Members has been extended and how integrative research and collaboration has been enabled. We strongly believe that with these extensions, CAS Toronto is well-positioned to face the challenges of applied research and make scientific advancements that are critical to the IBM mandate of a “Smarter Planet.”

Appendix: The Eight Major Research Initiatives The following eight research areas represent the priorities of the CAS Toronto research portfolio. They also reflect the key technology areas and business interests of the IBM Software Group at large. They are listed in alphabetical order.
Business Intelligence The term “Business Intelligence” (BI) was first used by Luhn from IBM Research (1958) to refer to “the ability to apprehend the interrelationships of presented facts in such a way as to guide action towards a desired goal.” In general, the purpose of business intelligence is to enable better business decision making (i.e. “action” in Luhn’s definition), closely tied with business performance management (i.e. “desired goal” in Luhn’s definition).
Scientific advancements needed for the maturity of technology adoption in business intelligence include business intelligence tools, business intelligence platforms that enable general BI capabilities like data mining, analytics, reporting, online analytical processing (OLAP), etc.
Related research topics include: ⇒ Enterprise data warehouse ⇒ In-memory analytics ⇒ Data mining ⇒ Decision optimization: analytics, mining, rules, filtering, etc. ⇒ Data visualization & interaction with visualized data ⇒ Intelligent Search ⇒ Business Intelligence as a Service (BIaaS)
Cloud Computing While there are many different definitions of “cloud computing,” CAS adopts the definition of cloud computing as a style of computing with three essential elements: (i) potentially massively scalable units of computing which (ii) are being delivered as a service to users (iii) via internet-related technologies. As a result, the users of these computing services are relieved from the burden of IT ownership (both hardware and software), maintenance and internal knowledge of these services. Instead, the users can now focus on the value of the services as a functional unit provided to them..
Cloud computing is generally considered an alternate paradigm in acquiring computing as a service, which is distinctively different from the traditional paradigm of purchase, installation, deployment and maintenance by consumers. By tremendously lowering the upfront cost, the cloud paradigm offers the appealing potential of bringing computing to average citizens at a price that is affordable, not just to the large enterprises who can afford it.
The most common scenarios of cloud computing are: Infrastructure as a Service (IaaS): delivering computer infrastructures such as storage and processing capacity as units of services to consumers. Platform as a Service (PaaS): delivering computing platforms and solution stacks as units of services to consumers. Software as a Service (SaaS): delivering units of software application capabilities as units of services to consumers.
Types of clouds include:
Author: Joanna W. Ng, IBM Canada Software Lab. IBM Canada Software Lab Center for Advanced Studies, Toronto “Extending CAS for Today’s Relevance” Page 10 of 13 Public cloud: in which the delivery of services is provisioned via the internet. Private cloud: in which the delivery of services is provisioned via the private intranet.
Related research topics include: ⇒ Cloud security and privacy ⇒ Cloud computing programming models and life cycle: model, develop, deploy, monitor, manage and adapt ⇒ Business models of cloud computing ⇒ Virtualization ⇒ Standardization, Openness & Interoperability of each layer of cloud computing
Database Technologies Database technologies are integral to CAS research, covering the control of the organization, storage, management and retrieval of data in a database.
Related research topics include: ⇒ Stream data ⇒ XML and text data ⇒ Query processing and optimization ⇒ Data mining ⇒ System performance ⇒ Database virtualization
Next Generation Systems Next generation systems are computing infrastructures and/or systems whose advancement will leapfrog the capabilities and/or computation capacities of their current generation counterparts. While there are many potential research opportunities under this umbrella, the following technology areas are the current focus: ⇒ Multi-Core Computing: the combining of two or more independent cores into a single circuit, programming model, tool and runtime architecture ⇒ Graphical Processing Systems: systems for 2D and/or 3D graphical computations and transformations ⇒ Stream Processing Systems: a computer programming paradigm that uses parallel processing across multiple computational units, such as floating point units on a Graphic Processing Unit (GPU), with a seamlessly integrated programming model, tool and runtime architecture
Service Oriented Architecture 2.0 & Smart Services Service Oriented Architecture (SOA) enables loosely coupled units of functions that are distributed in nature, called services, to be accessible, combined and reused over the network (Erl, 2005). One of the architectural goals of SOA is to enable ad hoc composition from existing software services whose diversity in runtime environment, implementation, programming language models and framework were encapsulated and abstracted.
The research area of “SOA 2.0” focuses on the advancement of science that enables the maturity and general adoption of SOA, as the “2.0” notation implies the “next generation” of SOA. “Smart Services” focuses on the advancement of science that releases the SOA services from the hands of software programmers into the control of the general end users. Smart services enable smart interactions.

IBM Canada Software Lab Center for Advanced Studies, Toronto “Extending CAS for Today’s Relevance” Page 11 of 13 Related research topics include: ⇒ SOA Programming Model, Life Cycle and Governance ⇒ Semantics of SOA services ⇒ Event Driven SOA ⇒ Service Discovery ⇒ Service Composition ⇒ Service Interface Patterns
Smart Interactions The evolution of the internet in the late 1990s focused on web applications and deployment technologies in order to adapt to the challenges imposed by the inherent web architecture. Starting in the early 2000s, new technologies flourished in an to attempt to provide a better user experience of the web. Rich Internet Applications (RIA) aim at providing rich media for the web that is comparable to its desktop counterparts (Allaire, 2002). Web 2.0 created the notion of “the web as a platform” to enable an architecture of participation, end user control and remixing of units of functions (O’Reilly, 2005). AJAX enables asynchronous interactions that offer new opportunities for user interactions (Garrett, 2005).
The research area of “Smart Interactions” intends to go beyond Web 2.0. It focuses on the scientific advancements that make the internet a smart and ubiquitous tool to support the individual user and his task in a manner that is timely, personalized, and with an optimal cognitive load, while allowing the user to maintain appropriate control over such interactions.
Related research topics include: ⇒ Mash-up and Situation Applications ⇒ Web Interaction architecture and framework ⇒ Ubiquitous computing ⇒ Context Aware interactions and architecture ⇒ Collaborative Interactions: sharing of tasks, interruption patterns, others ⇒ Conceptual models for web interactions, interaction patterns
Software Development Processes Software development processes are defined as structural methodologies, techniques, measurements and metrics employed in the development of software for a defined purpose. Typical goals of the software development process include an efficient software development life cycle, developing properly functioning software, fulfilling customer needs and others.
Related research topics include: ⇒ Disciplined Agile Development; large scale agile development Extreme Programming Scrum ⇒ Lean Software Development (development efficiency, business results, waste elimination, etc.) ⇒ Metrics visibility, monitoring and continuous improvement ⇒ User Experience, User Driven Development, Stakeholder Driven Development
Software Development Tools

Marin has been contributing to 2 key focus areas of CAS Research. In the CAS research project "Real time monitoring and simulations of business processes", Marin played an extremely valuable role in transforming the reserach results from this project into a working prototype in Websphere Business Modeler. Marin worked very closely with technical leaders and engineers of the Websphere Business Modeler development team, transforming product pain-points relating to process simulation into research problems, ultimately shaping the research result into a consumable form. The results from this project provides a unique competitive edge in the landscape of process simulation. The paper publication submission resulting from this project further attest to the work Marin's done.
In Cloud Computing, Marin continued his leading academic role in defining a reference architecture for layered cloud performance modelling and optimisation. Together with his CAS Research collaborators he developed new methods and techniques for cloud optimization. This work resulted in several prototypes and co-authored papers. With his CAS collaborators, he got the Best Paper Award at ACM SAC 2010. He also worked tirelessly to expand the CAS Research Cloud Computing community through presentations, workshops and by working with local and federal government agencies to fund research projects in the cloud computing area.

This award is presented to CAS Research Fellowship Projects or Strategic Research Grants which have produced output ready to go into TIL for harvesting, AND/OR output that has already been included in the product. This year's winner was:
High Scale, Low Touch Cloud Management
Researchers: Gabriel Iszlai and Andrew Trossman, IBM Canada Ltd.; Dmitrijs Palcikovs, Jack Yang, Johan Harjono and Madalin Mihailescu, University of Toronto
High Scale Low Touch is a massively scalable implementation of an Infrastructure as a Service cloud. Using peer to peer parallel and distributed techniques the system is extremely fast and reliable. It shows near linear scalability from a handful of systems to over a hundred and is expected to scale well into the thousands. Low human administration is achieved by the management system itself dynamically reacting to prevent, detect, and correct failures. This project demonstrates a breakthrough in management systems design and is expected to influence a broad set of management products in the future. In concert with SWG, the CAS Technology Incubation Lab created, experimented, and delivered this breakthrough technology.

2010 innovator of the Year Innovator of the Year is an award category which was introduced in 2008 as part of the CAS Technology Incubation Lab to recognize the contribution of CAS Affiliates. CAS Affiliates are individuals who take time, sometimes personal time, to work with us on innovative, ground- breaking projects, while building on their technical vitality and development.
The person who best exemplified these qualities was: Jin Li, IBM Canada Lab, Toronto; User Experience Architect, Rational software
As a long-time partner of CAS and an active CAS Affiliate, Jin's tireless dedication to and passion for innovation are exemplary. In spite of his demanding job as the Rational User Experience Architect, Jin is always ready to work on CAS research projects, even to the extent of giving up his personal time. His invaluable contributions were imperative to the successful delivery of several key projects. Living up fully as a Master Inventor, Jin never stops inventing and filing new patents. He is truly an innovator at heart and well deserved of this award.

First Decade High Impact Papers
As part of CASCON's 20th anniversary celebration this year, we are pleased to announce a special category of award, the First Decade High Impact Paper Award. This special award is to recognize past papers presented at CASCON which had delivered high industrial and academic impact. Headed by Hausi Müller, CAS Research's Visiting Scientist from the University of Victoria, a specially created 13-member selection committee was tasked with evaluating 425 papers published during the first decade. The high impact paper selection criteria were adapted from the ACM SIGSoft Impact Project and the Journal of the American Society for Information Science (JASIST) published by John Wiley & Sons. Impact and professional merits were the 2 key criteria used to produce a balanced mix of academic and industrial papers. The selection process had 2 phases and took 2 arduous months to complete. CAS Research would like to take this opportunity to thank the selection committee for their considerable time and effort. There are 14 winners for this First Decade High Impact Papers Award. All the selected papers are featured in a special CASCON proceedings volume.

Title: Web Services Tagging Architecture Principal investigator: Jim Cordy Project participants: Name Affiliation: [email protected] Queen's University Douglas Martin IBMer Scott Grant Queen's University Asil Almonaies Queen's University Joanna Ng Queen's University Summer Ugrad TBA IBM CAS Canada Queen's University
Proposal Abstract: Web services tagging addresses the issue of automatically identifying and tagging web services descriptions in three dimensions: by domain, according to domain concepts provided or implemented by the service; by physical structure, according to the set of service ports provided by the service, and by interaction structure, according to the style or paradigm of service interaction used by the service. Web services tagging can assist in rapidly matching services to the goals and intentions of both end users in finding appropriate services available in particular domains, and service providers in matching existing services for creation of new mashups and bundled services. For example, given a set of specific goals, a tagged service registry can automatically provide the set of all known services that may be relevant to the need.
In this project we exploit techniques derived from software design recovery to automatically analyze and tag WSDL service descriptions given a domain ontology for the service application domain. Based on our previous work in analysis and tagging of web pages and legal documents, we will exploit contextual clues to identify higher level concepts as well as basic entities provided or related to the service. As well as domain-specific tags described by the ontology, our system will use port and interaction patterns to tag services according to their port architecture and interaction style independent of domain, so that services can be matched not only by their relevance to the domain information, but by their ability to cleanly mash up and interact with other services.
In the first year of this project we designed and implemented tools for parsing and restructuring service descriptions for more effective analysis and tagging using source transformation techniques to localize operation descriptions into self-contained "Web Service Cells" (WSCells) which can be understood and analyzed independently. These first tools have been used by other CAS projects for understanding and manipulating WSDL service descriptions. In the second year of the project we concentrated on similarity detection among services using clone detection techniques on WSCells to recognize and categorize similar services. Our results have been released as a WSDL service similarity tool distributed as part of the NiCad clone detection system which has begun to be used by other researchers.
In this year we refocus to a more general goal, the provision of a single comprehensive tool for understanding, manipulating, tagging and comparing WSDL service descriptions. We will extend our reverse engineering to extract a richer set of WSDL attributes, generalize our similarity analysis to cover other dimensions of service descriptions in addition to operations, extend our work on conceptual semantic analysis of services, and add a multi-dimensional interface to assist web service engineers in understanding and manipulating WSDL-based service suites. The goal will be a complete "WSDL workbench" for conveniently understanding and manipulating WSDL-based service suites.
The need for such a tool is motivated by the feedback of IBM researchers, developers, service providers and their customers, who when introduced to our work have repeatedly asked the same question: "can you help us to understand our WSDL services?" While WSDL is widely used as the standard for web service descriptions, developers and users find it complex, difficult and confusing to understand, and they welcome our analysis as a way to help them with the task. By refocussing our work explicitly on this need, we hope to have a more direct impact on IBM developers, service providers and customers as they transition to the Smart Internet.

Title: Predicting business impact of introducing new composite applications and services to a single or federated ESB by analysis and modeling of service interactions Principal investigator: Hans-Arno Jacobsen Project participants: Name Affiliation: [email protected] University of Toronto Allen Chan IBMer Phil Coulthard IBM Canada Young Yoon IBM Canada Vinod Muthusamy University of Toronto Chunyang Ye University of Toronto Siddarth Ganesan University of Toronto University of Toronto
Proposal Abstract: It is common for large enterprises to rely on dozens of composite applications and many business processes which draw on and integrate hundreds of independently developed services and systems that communicate and are coordinated by single and federated enterprise service buses (ESB). In such an ecosystem a simple change at the business level or a change in the implementation of a service may have unforeseen impact on the overall business operation, directly effecting revenue and cost.
For example, the introduction of a new sales promotion process may not have the desired effect of increasing key performance indicators (KPI) tracking sales, but rather show a drop in sales and an increase in process turn-around times. Similarly, the exposure of a service, correctly working at the department level, to the whole enterprise, may result in a rise of service and process latencies, possibly combined with an increase in transaction roll-backs.
The fundamental question is, that given the complex enterprise ecosystems' of today, -- including internal and external services, composite applications and processes, -- could the impact of a change at the business or at the system level be anticipated? Could the analysis revealing the impact be conducted with the tooling used by Business Analysts and IT Administrators who drive the envisioned top-down business modeling and operate the deployed applications, -- for example, by enhancing WebSphere Modeler with business impact analysis capabilities, -- before changes effect the operation, the KPIs, and the cost and revenue? Could the impact be mitigated or be dynamically isolated by adequate semi-automatic and assisted planning, and by corrective actions?
More than ever before, federated service-oriented architectures are characterized by high degrees of re-use, by unprecedented sharing of resources, and by myriads of dependencies. Fueled by the cost-conscious multi-tenancy nature of enterprise ecosystems today, business impact analysis is a severe challenge whose effective resolution will differentiate the successful enterprises of tomorrow.
The nature of the problem lies in the reuse of services and sharing of infrastructure resulting in significant cost savings as services once developed are shared among applications across the enterprise. However, it is exactly this key principle of SOA that imposes severe challenges, as the effects and implications of service re-use and infrastructure sharing may create contention among already running composite applications and processes that make use of the shared resources.
There is a conflict arising from three requirements of a federated SOA: (1) having a *shared* infrastructure administered by one entity to amortize resources and cost, (2) the ability to spontaneously discover and compose *independently* developed services to quickly react to changing requirements, and (3) the desire for *isolating* the behavior of separate applications so as to not affect one another.
The objectives of this research are to understand and resolve this conflict by developing business and systems impact analysis techniques. This research will develop techniques to discover the interaction among services aiming to minimize the impact on the running system (i.e., all composite applications and processes), develop models to predict the effects the change and the sharing of services has on already running composite applications and processes, and develop techniques for isolating composite applications and processes despite sharing and re-use.
The project objectives were refined throughout a series of discussions organized in November 2009 by Allen Chan and Phil Coulthard with Pablo Irassar, Brian Petrini and Marc-Thomas Schmidt.
This project touches upon issues directly relevant for business modeling, monitoring, iterative development, business impact analysis, predictive analysis, business process management, and connectivity. Overall, this research will significantly increase the chances of success for the envisioned top-down business modeling approach driving the development of WebSphere Modeler by developing novel concepts and techniques that help to close the gap between Business Analysts, IT Developers and IT Administrators.

Title: Lightweight (WS* and REST) Service Orchestration Principal investigator: Eleni Stroulia Project participants: Name Affiliation: [email protected] University of Alberta IBMer
Proposal Abstract: Web services can be operation-centric (WSDL) or data-centric (REST). REST services can be specified in WADL or WSDL 2.0. Services are combined and their composition is specified in BPEL. Although BPEL provides the syntax in terms of which to compose WSDL and WADL services (i.e., procedural and data centric services), to date there is not design-level support/guidance on the proper way to combine services, at the semantic level. The goal of this work is to establish a common semi-formal model (based on UML) for multiple syntactic languages for services and their compositions, including WSDL, BPEL, BPMN, and WADL. The abstract specification will focus on services and data (UML class diagrams), message exchange (UML Sequence diagrams) and constraints and semantic information (OCL).
Once this model has been established, we will proceed to develop methods and tooling for a suite of reasoning tasks, including
1) service discovery for the purposes of fulfilling specific composition needs, as differencing of the desired service model against the models of the available services;
2) composition of services, specified in potentially heterogeneous syntactic specifications, as alignment and merging of the corresponding abstract service models; and
3) refactoring of existing compositions to include desired service-interaction patterns, as alignment and merging of composition models and service-interaction models.

Title: Service City: An End-User Centric Infrastructure for Service Discovery, Composition, and Sharing Principal investigator: Ying (Jenny) Zou Project participants: Name Affiliation: [email protected] Queen’s University Joanna Ng IBMer Bipin Upadhyaya (PhD Fellowship IBM Employee Student) Queen's University Hua (Michael) Xiao Queen's University
Proposal Abstract: Service-Oriented Architecture (SOA) uses loosely coupled services as basic constructs to compose larger systems. SOA systems can be built in a relatively low-cost and rapid way. However, the current service composition programming model and tools are mainly designed for professional SOA developers to solve business problems. It is challenging for end-users without professional SOA knowledge to integrate SOA technology in their daily on-line experience. In this project, we aim to build an infrastructure for end-users to discover, compose and share services in a dynamic run-time environment. The results of our research reduce the needed skills of end-users in the various stages of service composition.

Title: Framework for the Deployment and Use of Legacy Enterprise Services Utilizing the REST Protocol Principal investigator: Kostas Kontogiannis Project participants: Name Affiliation: [email protected] NTUA Michael Athanasopoulos IBMer Chris Brealey NTUA IBM Employee
Proposal Abstract: Over the past decade we are experiencing a steady growth on software applications that are based on the Service Oriented paradigm, and in particular Service Oriented Architecture. As enterprises have started implementing and deploying successfully such Service Oriented systems, the interest and complexity of the related technology started also growing in a fast pace. The area is currently witnessing a plethora of protocols and standards that grew to a point that requires highly specialized programming skills for someone to design, implement, test and deploy such systems. This creates the need for appropriate infrastructure, models, and practices to be put in place so that analysts, developers and end-users can better and faster rip the benefits of Service Orientation without the need to know all the details of the underlying technology but rather being able to focus on what matters the most, that is the business logic and services behind these large corporate systems. The project aims to devise novel techniques that allow for the seamless utilization of REST and WS-* types of resources and components with the purpose of integrating and composing large scale enterprise systems in a mashup style.

Title: Effective Consistency Management and Impact Analysis in Business Process Modeling Principal investigator: Krzysztof Czarnecki Project participants: Name Affiliation: Krzysztof Czarnecki University of Waterloo [email protected] IBMer Moises Castelo Branco University of Waterloo Yingfei Xiong University of Waterloo Phil Coulthard IBM Toronto Jochen Küster IBM Research Zurich
Proposal Abstract: Business Process Modeling (BPMo) is a collaborative task of different groups of specialists, including business analysts, solution architects and system developers. They work on different levels of abstraction and collaborate to create a set of different but related models, ranging from high-level process specifications to executable models. Our objective is to improve support for consistency management and impact analysis in BPMo. In particular, we aim to (1) advance our understanding of the relationship between models that target different levels of abstraction and how to characterize consistency among them; (2) develop techniques to support traceability among the models; and (3) develop techniques to support consistency checking and generate fixing actions for inconsistencies introduced after independent editing.

Title: Optimization of progressive queries in a database management system Principal investigator: Qiang Zhu Project participants: Name Affiliation: [email protected] The University of Michigan Chao Zhu IBMer Calisto Zuzarte The University of Michigan IBM CAS Canada Research
Proposal Abstract: The main goal of this project is to investigate the issues and techniques to efficiently process a new type of query, called progressive queries, which has become increasingly important in many contemporary database applications such as telematics, e-commerce, business intelligence, and decision support. Unlike a conventional query, a progressive query is formulated in several steps, i.e., consisting of a set of inter-related step-queries. Moreover, neither the query processor nor the users know a priori the step-queries of a progressive query. Users rather formulate their step-queries on the fly based on the results returned by the previous step-queries and their expertise in interpreting those results. Processing such queries raises new challenges for a database management system (DBMS). The query processing and optimization techniques in existing DBMSs were not designed to efficiently handle such progressive queries. In this project, the characteristics of progressive queries will be studied, the techniques to optimize and process such queries will be explored, and the developed techniques will be evaluated in a real DBMS environment such as DB2. The applications of progressive queries to enhance ETL and OLAP tools will also be explored. The issues addressed in this project are crucial in efficiently processing a new advanced type of query in DBMSs. The resulting technology will advance the state of knowledge for query processing and optimization in the database area. The success of this research will have a significant impact on current DBMSs to meet users' emerging demands in today's competitive market.

Title: Green Databases: Rethinking DBMSs for the New Planet-Aware Era Principal investigator: Josep Larriba-Pey Project participants: Name Affiliation: Josep Larriba-Pey DAMA-UPC [email protected] IBMer Sergio López Montolio DAMA-UPC Sunil Kamath IBM Adriana Zubiri IBM
Proposal Abstract: Energy consumption in data centers is becoming one of the top concerns. Data-center power consumption in the US doubled between 2000 and 2006, and is still continuously growing [EPA07]. This has lead governments across the world to seek to regulate enterprise IT power. Besides environmental motivations, reducing memory consumption, and thus heating, is becoming mandatory. Recent studies show that 50% of all electronic failures are related to overheating [Lian03]. On top of this, energy consumption has already surpassed the budget earmarked for hardware acquisition, making it also important to reduce energy from an economical point of view. Hardware designers have strengthen their efforts to reduce power and cool down devices. Several techniques try to deal with these issues by moderating CPU frequencies, designing hardware that minimizes power consumption while in the idle state, or by proposing sensor-controlled fans and cooling systems. In spite of these efforts, modern hardware, for instance, still consumes more than a half the peak energy even when idle. Also, it is well-known that, although most data centers are configured to work in their peak capacity, the real average workload rarely justifies the amount of active resources in the system. In addition, despite the maximum execution-time formally agreed with customers through service level agreements (SLA) does not always demand for extreme high- performance, systems are still designed to answer queries as fast as possible, at the cost of keeping hardware at high frequencies and voltages, thus consuming unnecessary energy. Data management systems offer a great opportunity in order to reduce energy consumption. DBMSs have been devised in general to prioritize performance and throughput, but have largely ignored power-related aspects. In this project, we aim at rethinking DBMSs to make them more aware of energy consumption, including power reduction as one of their priorities. Key aspects that will be addressed range from smartly using the remaining time left over by service contracts using SLAs, by managing the system workload according to the priorities of its tasks, to both exploiting hardware improvements designed for energy efficiency and finding new techniques to save energy, independently of the hardware employed and its energy-saving features.

Title: Access Methods for Hybrid In- and Out-of-Core DBMSs Principal investigator: Victor Muntés-Mulero Project participants: Name Affiliation: [email protected] DAMA-UPC Joan Guisado-Gámez IBMer Josep-Ll Larriba-Pey DAMA-UPC Antoni Wolski DAMA-UPC IBM Employee
Proposal Abstract: Real applications do not always allow keeping the whole data set in memory, forcing the systems to combine in-memory and out-of-core techniques, or even to swap from in-memory to out-of-core in some cases. In this situation, access methods become especially important since they allow mapping the actual storage of data to the real access of the operations performed on the records processed. A proper mapping of the access methods for both in-memory and out-of-core DBMS storage would allow increasing the memory locality in both situations, improving the throughput of DBMSs as an average. In this project we will work on the use of the memory hierarchy for in-core and out-of-core DBMSs, taking a special look at SolidDB as a specific example. We will work on access methods that are respectful with in-memory and out-of-core data, paying also attention to the mapping of the access methods to the memory hierarchy. The importance of multicore processing power will be cared for because there is an important synergy between the ways data are managed in the memory hierarchy and the way processors access the data.

Title: Autonomic Workload Management in DBMSs Principal investigator: Patrick Martin Project participants: Name Affiliation: [email protected] Queen's University Mingyi Zhang IBMer Keith McDonald Queen's University Paul Bird IBM Employee Wendy Powley IBM Employee Natalie Gruska Queen's University Queen's University
Proposal Abstract: The current trend for enterprises to consolidate different workloads, such as BI and OLTP, onto a single database server, means that the management of the database management system (DBMS) is becoming increasingly complex and costly. In addition, workloads submitted by different applications, or from different business units, typically have unique performance requirements that need to be satisfied. Workload management, which is the discipline of effectively controlling and monitoring work flow across computing systems, can be an effective approach to the problem. We developed several workload management techniques, such as query scheduling and query throttling, in previous CAS projects. In this project we are developing a framework for using these techniques in a coordinated way. We will evaluate the use of our framework for workload management under two key scenarios that we call the fail-safe scenario and the customer-SLO scenario. In the fail-safe scenario, workload management is employed to ensure that the DBMS does not become over-utilized and hence unable to process its workloads while still maximizing system efficiency. In the customer-SLO scenario, some of the workloads have performance requirements expressed as SLOs and workload management is used to ensure that these workloads meet their performance objectives while perhaps having to sacrifice the performance of the other workloads.

Proposal Abstract: PGAS environments are getting widely acceptance for executing parallel applications on distributed memory architectures. There are a number of languages that are built with PGAS support: UPC and Co-array Fortran, X10 and Chapel. In this project we optimize various aspects of the PGAS execution environment. Remote memory access latency will be reduced through the use of data aggregation, prefetch and caching techniques. Prefetch will allow to overlap computation and communication. The implementation will be done with a combination of compiler transformations and runtime support. Fine grain tuning of various parameters, like buffers sizes, will be needed to achieve good performance. As both UPC/Co-Array Fortran, and X10 languages run on top of PGAS, this project will benefit the execution of them all.

Title: OpenMP and PGAS Enhancements for Manycore Processors Principal investigator: Vivek Sarkar Project participants: Name Affiliation: Vivek Sarkar Rice University [email protected] IBMer Sanjay Chatterjee Rice University Raul Silvera IBM Toronto Kit Barton IBM Toronto Guansong Zhang IBM Toronto
Proposal Abstract: Over the last 12 years, the OpenMP programming model has evolved into a widely-used standard for programming symmetric multiprocessors (SMPs) and multicore processors. Its pragmas, or directives, greatly simplify the software challenges of portability and maintainability when developing parallel programs. OpenMP originally primarily supported the parallelization of loops via distribution of their iterations across a modest numbers of processors. It was recently enhanced to support a much larger class of applications via the addition of user-specified tasks. More recently, PGAS models such as UPC and CAF have extended the concept of shared-memory parallel programming to clusters of distributed-memory multiprocessors. However, if OpenMP and PGAS are to be relevant programming interfaces in the future, they need to take into account the changes under way with the use of manycore processors as building blocks for next generation systems. In this project, we propose to explore enhancements to OpenMP and PGAS models that address the scalability and locality challenges posed by manycore platforms. Our proposal will provide programming models enhancements, compiler optimizations and runtime optimizations to support scalable synchronization on manycore processors, by building on past work on the "phasers" construct at Rice University. These enhancements and optimizations will be evaluated on a range of applications in the context of IBM's XL product compilers. These prototype implementations should help IBM make a convincing case for championing whichever extensions to OpenMP and PGAS models are best suited for IBM's future customer and product needs.

Title: Managing Dynamic Context to Optimize Smart Interactions and Smart Services Principal investigator: Hausi Muller Project participants: Name Affiliation: [email protected] University of Victoria Norha Villegas IBMer Joanna Ng University of Victoria Juan C. Munoz IBM CAS Director Student from Icesi University - Cali Colombia
Proposal Abstract: The Personal Web is the people-centric instantiation of the Smart Internet where information systems, services and web content are articulated by users according to their matters of concern. To realize the vision of the Personal Web, the Smart Internet requires infrastructure to support the user in the integration of personal data and the composition of personal services within a highly dynamic context that constitutes the user’s Personal Web Sphere [Ng10]. To address these requirements, we propose a user-driven context management framework, built on top of the basic enabling infrastructure of the Personal Web, to support users in the run-time modification of personal context models. The core of our proposal is the management of monitoring concerns by implementing feedback loops, where the user acts as the planner of the controller to adapt the monitoring strategy by means of web interactions to modify the personal context models. These context models, deployed at three different levels of abstraction, represent monitoring concerns by defining abstract types of contextual entities, the relationships among them and the interactions that the user can instantiate to drive web integration [VMNL10].
This project consists of the following major parts and subparts:
(1) definition of context meta-models and context models to be integrated to data model of the Personal Web; (2) investigating web and service-oriented software architectures and infrastructure, as well as methods and techniques for: (a) dynamically discovery and adapting smart interactions and smart services to enable user driven web integration; and (b) enable the user for controlling the adaptation of context models through smart interactions; (3) implementing a proof of concept for evaluating preliminary results.

Title: A Ubiquitous Context-Aware System for Smart Operating Rooms Principal investigator: Yelena Yesha Project participants: Name Affiliation: Yelena Yesha University of Maryland [email protected] IBMer Aniket Bochare University of Maryland
Proposal Abstract: The progress of technology has transformed the way surgeries are performed. Traditional methodologies involved most of the surgical process, including low level event tracking to the broader details recording of the surgery to be carried out by the surgical staff. Computerized tools have been developed which simulate surgical procedures and/or experiences can allow for “virtual” experiences to enhance the traditional training procedures that can dramatically improve upon the older methods. However the responsibility of tracking medically significant events and record keeping still lies with the surgical team. We describe a pervasive context-aware system which can automatically capture and interpret data in a “smart” operating room and maintain a context model of the surgical procedure, detecting medically significant events. Such a system can greatly benefit the healthcare industry and thus mankind through the use of science.
This project is related to IBM’s smart interactions research Initiative which focuses on developing smart and ubiquitous tools to support individual user and his or her task in a timely, personalized and optimal manner while allowing the user to maintain appropriate control over such interactions. The proposed system aids the surgical team in all the phases of the surgical procedure in an ubiquitous environment while allowing the surgical team to take appropriate actions at the right time by providing alarms and indications in case of emergency events.
The more specific abstract of our current research is as follows:
Laparoscopy is a type of minimally invasive surgery in which a small incision is made in the abdominal wall through which an instrument called a laparoscope is inserted to permit structures within the abdomen and pelvis to be seen. Laparoscopic cholecystectomy is surgical removal of the gallbladder by laparoscopic techniques. The procedure requires several small incisions in the abdomen through which surgical instruments and a video camera are placed into the abdominal cavity. The camera transmits an image of the organs inside the abdomen onto a television monitor. The surgeon is not able to see directly into the patient without the traditional large incision. The video camera becomes a surgeon’s eyes in laparoscopy surgery, since the surgeon uses the image from the video camera positioned inside the patient’s body to perform the procedure. Due to the lack of tactile sensation and three dimensional visual feedbacks, there are possibilities of certain surgical injuries occurring to the adjacent structures such as the common bile duct, duodenum or the small intestine. One such serious injury would be cutting of the cystic artery. The objective of this research is to detect the presence of such risk from the images of laparoscopic cholecystectomy and alert the surgical staff of a potential danger. The system would run on multicore processors to achieve near real-time results. We would be working with simulated videos of laparoscopic obtained from University of Maryland Medical Centre (UMMC) throughout this research.

Title: End User Development of Advanced Visual Interfaces Principal investigator: Margaret-Anne Storey Project participants: Name Affiliation: Lars Grammel University of Victoria Margaret-Anne Storey University of Victoria [email protected] IBMer
Proposal Abstract: Fast changing business models of organizations and increasingly demanding tasks for knowledge workers in companies require flexible software systems that can be adjusted to organizational and individual demands easily. This is reflected in the growing importance of service-based architectures and service orchestration, as well as personalization of Enterprise Portals. Business experts are likely to perform more programming-like activities in restricted domains, including the creation of advanced visualizations for reports and awareness.
Enterprise portals already provide the possibility to create and customize reports or web-pages. Unfortunately, end-users lack tools and knowledge to create and maintain advanced visualizations, which inhibits leveraging the advantages of such visualizations for a bigger audience. To address this issue, our collaborative project between the IBM Toronto Lab and the University of Victoria will explore how end-users can be supported in creating and modifying visualizations.
As a first step, we will explore how end-users naturally describe the mappings and operations in the different steps of information visualization. The results will be used to create prototypes of end-user visualization development environments, which will be further refined in later steps. Over the course of the project, we will further explore how end-users collaborate in creating visualizations, how they maintain them and how we can provide active guidance that leads to better visualization choices.
Throughout this project, our approach will be to emphasize the end-users’ perspective and to understand their natural approaches to information visualization, in order to better understand the trade-offs in designing a system that is both easy to learn and yet offers complex functionality. Our goal is to design information visualization environments that allow time- efficient creation and maintenance of advanced visualizations, based on sound empirical understanding of the users’ needs.

Title: Practical Ontology Framework Principal investigator: Igor Jurisica Project participants: Name Affiliation: [email protected] OCI & UofT Daniela Rosu IBMer DCS, UofT
Proposal Abstract: Ontologies, from the formal specifications of domain conceptualization to the very informal folksonomies are increasingly seen as a key technology for facilitating knowledge exchange due to their supporting role in describing the semantics of information. They are applicable to a wide number of areas such as bioinformatics, e-commerce, semantic web and grid computing. As the number of applications increases, challenges associated with knowledge (ontology) engineering and management grow significantly. Among the many applications of ontologies we have chosen to investigate tag recommendations strategies, structure extractions from annotated resources and a framework for developing lightweight, practical ontologies, which would provide practical ontology framework diminishing negative aspects and increasing positive features of folksonomies and formal ontologies.

Title: PERSONAL WEB & BUSINESS ANALYTICS FOR HEALTHCARE Principal investigator: Mark Chignell Project participants: Name Affiliation: Mark Chignell University of Toronto [email protected] IBMer Ryan Kealey University of Toronto Mahsa Rouzbahman University of Toronto Hao Shi University of Toronto Stephan Jou IBM Business Analytics Ilse Breedvelt IBM Business Analytics Steve Macko IBM Business Analytics Shadi Ghajar-Khosravi University of Toronto Shadi Ghajar-Khosravi University of Toronto
Proposal Abstract: Two recent developments at IBM have strong implications for work in the healthcare domain, the launch of the Personal Web initiative (Joanna Ng, 2010) and the formation of a powerful Business Analytics unit that includes both Cognos and SPSS. Through our own research we have identified possible applications of these technologies to issues in healthcare.
This research is motivated by previous findings showing that high quality information can change practice (for the better) by providing physicians with relevant evidence when they make decisions. By its nature clinical evidence takes time to accumulate, synthesize, and disseminate, even in the age of the Internet. Furthermore, to be practicable, evidence tends to be aggregated over groups of people and refers to relatively few variables at a time. But what of clinical decisions that are highly context-dependent, involve complex sets of variables and patients who differ from established groups in important ways? How can we support clinical decisions in cases where high quality synthesized clinical evidence is not yet available, but where there might be detailed data that potentially has a bearing on the decision? We propose the development of a cloud-based analytic system to enhance clinician decision making by selecting relevant data, archiving and performing statistical, text and data mining procedures in order to provide access to relevant, meaningful summaries of patient data that can then be explored and assessed in order to infer clinical evidence hidden in the data.

Title: Modeling Rich Internet Applications for Security Principal investigator: Guy-Vincent Jourdan Project participants: Name Affiliation: [email protected] University of Ottawa Gregor V. Bochmann IBMer Emre Dincturk University of Ottawa Suryakant Choudhary University of Ottawa University of Ottawa
Proposal Abstract: Web site security is a top priority for protecting sensitive company, customer, and employee data, for meeting regulatory and corporate compliance requirements, and for defending against the high cost of a data breach. The Rich Internet Applications, present additional challenges for security because of the Web pages executed at the client side may contain powerful program fragments that may execute concurrently, asynchronously and may be hidden from the view of the user. The proposed research is directed towards improving the methods and tools for generating test sequences that can uncover security vulnerabilities of such applications. More specifically, we plan to develop paradigms for modeling a given rich internet application and its data flow, to provide algorithms for automatically building such models, and to demonstrate the applicability of our methods by using such a model for generating test sequences to uncover security flaws. The initial focus of our work will be the detection of injection faults. We plan to develop prototype tools that could provide a proof of concept for the security testing methods developed within the project.

Title: Context-Aware Correlation-Based Program Optimizations Principal investigator: Xipeng Shen Project participants: Name Affiliation: Xipeng Shen The College of William and Mary [email protected] IBMer Bo Wu The College of William and Mary Yaoqing Gao IBM Employee Raul Silvera IBM Employee
Proposal Abstract: Accurately predicting program dynamic behaviors is the basis for program optimizations. Current static compilers suffer from runtime unknowns and input-sensitive behaviors. In this project, we aim at developing a context-aware correlation-based paradigm for program behavior prediction. The new paradigm distinctively exploits the correlations among the behaviors of different components (e.g., loops, procedures) of a program. It will enhance the capability of modern compilers in handling input-sensitive behaviors, and hence open up many new opportunities for program optimizations. We will concentrate on the application of the paradigm in program code specialization, a key approach to extending the power of static compilation— such as, loop optimizations, software prefetching, function inlining, speculative execution—into run time in a simple and effective manner. The new ways of behavior prediction will eliminate some obstacles for the selection of appropriate code versions, substantially expanding the applicability and effectiveness of code specialization in current compilers (e.g., the IBM XL compilers). Our preliminary experiments demonstrate promising results of the new technique on a set of SPEC CPU benchmarks. We will use IBM Toronto Portable Optimizer (TPO) as the major infrastructure for this research.

Title: Incremental, Multi-User Consistency Checking Principal investigator: Alexander Egyed Project participants: Name Affiliation: Alexander Egyed Johannes Kepler University, Austria [email protected] IBMer Alexander Reder Johannes Kepler University, Austria Dan Leroux IBM Ottawa Alan Yeung IBM Ottawa Harold Ossher IBM Watson
Proposal Abstract: We previously developed a technology for the fast and incremental detection and tracking of inconsistencies. Inconsistencies are a sign of error or incompleteness – possibly even a sign of “bad smells” as in violations to good practice rules. Most development tools are able to tolerate such inconsistencies. However, it is our belief that engineers should know about their existence to avoid follow-on errors and unnecessary rework. With our technology, we are now able to detect and track such inconsistencies in real time – in a manner that does not require manual overhead. The approach is quick, correct, scalable, and fully automated.
The current solution was specifically developed for single-tool/single user (e.g,. engineer) consistency checking. Yet, software development involves many engineers and many diverse sets of tools to cope with the multitude of different development artifacts including requirements, design models (e.g., UML), process models, test scenarios, or code. This work proposes to extend the current, single-user consistency checking technology for multi-user/multi-tool support. Multi user support has some fundamental differences to single user support. On the trivial side, it requires our infrastructure to run on a server infrastructure because it is the only place where all the development artifacts are available. On the complex side, we need to deal with private and public workspaces since engineers typically prefer to work in their respective private workspaces yet need to validate the consistency of their work not only internal to their private workspaces but potentially across public workspaces and possibly private workspaces of other engineers. This work thus needs to address issues of how to identify and resolve conflicts where multiple users make contradictory changes in context of an environment with real-time feedback despite the fact that the server may have to support multiple development projects and a large number of engineers. The latter aspect is complicated by the fact that performance drops with increasing number of users and our current consistency checking “in memory” is no longer feasible in context of large data volumes – requiring a more sophisticated mechanism to deal with memory/disk swapping optimized for consistency checking.
This proposed work is applied research as we plan on demonstrating our results in form of tool integrations with up to three ongoing IBM development projects: the Jazz/CAM, Rational Software Architect (RSA) and BITKit where the Jazz/CAM is a server and RSA/BITKit are potential client apps.
Relevant publications: In terms of the work we are planning to do under IBM CAS, Vio Onut expressed interest in having this technology patented. Therefore, we are currently refraining from publishing about it. No publications were thus submitted. We are planning to submit a paper in the next few months about the basic infrastructure that Andreas Gruber developed in his Master’s thesis (which is now funded under FWF). This should be non-controversal in terms of patent issues since it was pre-existing work but we will provide Vio Onut a copy in time to review it. We plan on acknowledging the IBM in that work due to the industrial transition intent without revealing any of the details of this project.

Keynote Speaker - Brenda Dietrich, IBM Fellow and Vice President in the IBM Research Division Title: Analytics for a Smarter Planet
FoSP - Joanna Ng, Head of Research IBM Canada CAS Title: The Personal Web Location: Cousens Conference Center 2 Time: 17:00 - 18:00 Description: The World Wide Web was originally designed for the access of distributed content, served as web pages from different web servers. The centerpiece of the first generation web is hypermedia links, used to traverse across different web pages from the server side. In the first generation web, web users are second class citizens, who have no choice but play the role as “web workers” and the manual operator of the web, bearing the onus of threading through, by hand, particular but complicated sequence of links; using point-and-click within a browser session, in order to accomplish users’ tasks over the web. The ramifications of the lack of cognitive optimality and its resulting mental burden upon the web users are too significant to be ignored.
The vision of the Personal Web is to make web users the center piece of the web and turn all web artifacts into second class citizens that work for web users behind the scene. We propose an extension of the web such that web users are promoted from its current state of “web workers” into “web supervisors” by significantly reduce the cognitive effort required, such as freeing web users of the burden of prospective memory tasks (Hicks et al., 2005), that we must “remember to remember”, as users use the web to accomplish their tasks and goals.
This session provides a conceptual and technology overview with a highlight of potential application in Smarter Commerce.
Joanna Ng is currently the Head of Research at IBM Canada Software Laboratories, Center for Advanced Studies. She is also a Senior Technical Staff Member of IBM Software Group. She has held various senior management and architect positions within IBM in product development teams and in software strategy division. Joanna is an IBM Master Inventor with a long track record of profitable innovations. She has conceived and led incubation projects within IBM Software Group and had a track record of nurturing them into commercialized products. Joanna has been granted over twenty five patents from various countries in research areas such as mobile commerce, voice-enabled portal, commerce portal, retail industry solutions; service-oriented architecture (SOA); asset repository; semantic and web technologies.

Users are encouraged to assign freely chosen keywords (“tags”)
Tags are displayed as a “cloud”, where more popular tags are drawn in larger text
19 ® Tagging reveals what people know
20 20 ® Why tagging works
Tagging taps into what people naturally do without creating a lot of work or requiring deep thinking
For an individual, tags, optimize future findability
Tags are malleable
Tag clouds provide immediate social feedback You can get positive reinforcement or become a trend setter Tag clouds give surprising insight into the content and the people Expertise can be revealed The real corporate taxonomy emerges

Server Browser Server Browser
In the typical web application, An Ajax application begins the same way. each request causes a complete refresh of the browser page After the initial page loads, Javascript code retrieves additional data in the background and updates specific sections of the page
Ajax forces you to think about discrete services. It may drive requirements for new services from your IT department
23 ® Beyond the hype
Coding Ajax applications is very complex and inconsistent e.g. Google Mail uses completely different JavaScript libraries than Google Maps Some companies report only 1 in 40 candidates have the necessary skills There are plenty of pitfalls: Subtle browser inconsistencies, complex JavaScript Back button, bookmarking, losing your state Hard to index pages for search Cross-domain security restrictions Latency Performance is not always better Trading off a few large requests vs. many small requests
24 ® The web as a universal platform
The trade off between “rich” and “reach” is disappearing due to advances in web standards
3 techniques: Pure browser, using AJAX Run outside the browser, but use browser code as middleware (XULRunner, Webkit) Expand browser capabilities with plugins (Flash, Sliverlight)

Profiles IBM’s internal BluePages application holds 475,000 profiles and serves 3.5 million searches per week, 1.5 million profile views per day. It is the hub of both user requests and all app authentication for IBM.
Communities IBM Community Map hosts 900 communities. IBM Forums hold 147,000 threads and 410,000 messages. Blogs IBM’s BlogCentral hosts 27,300 weblogs (420 group blogs) with 62,000 entries and 60,000 comments, and 10,800 distinct tags.
Bookmarks IBM’s internal Dogear system has 327,000 links from 8,511 users. One-third are intranet links and only 2.5% are private.
Activities IBM’s internal Activities service has seen all content and usage statistics grow to 25,000 activities, 180,000 entries and 53,000 users.
34 ® Characteristics to look for
Users get personal value first, independent of broader participation
Users see even greater rewards when sharing takes place
Self-organizing methods are used to build vibrant communities
Simple user experience is prioritized over advanced features
Remixing is enabled as a top priority (look for REST interfaces, syndication, mashup “widgets”, etc.)
35 ® Creating a climate for successful adoption
Choose organizations which have the greatest need for sharing tacit knowledge: look for people involved in researching technology or market trends look for people tasked with generating new product or service proposals Cross-discipline interactions (e.g. policy makers + researchers)
Seed the effort with “information mavens” A few blogs account for most of the readership, so create incentives for the few
Establish conduct guidelines When you blog, are you speaking as an individual or an official? Is it okay to keep personal bookmarks in the system? What topics are fair game for communities? How will you monitor this?

37 Slide 1
Web 2.0 and the Changing Workforce Carol Jones, IBM Fellow Slide 2
Are these technologies just a lot of buzz words? Or do they have real, lasting impact?
Slide 3
There are three broad software patterns associated with Web 2.0
The first is software as a service. It enables end users to adopt capabilities directly, and gain immediate benefits from it. Many Web 2.0 offerings have a very low cost of entry – another distinguishing characteristic that levels the playing field for small businesses. And of course they use the public infrastructure, so anyone in the world can walk up and use it with a web browser.
The second key pattern is the use of community mechanisms. Most Web 2.0 businesses use one or another kind of mechanism to enable users to play a part in the service, adding value as they use it. For example, eBay uses ratings to measure the reputations of vendors, which leads to more trustworthy transactions. Others include all kinds of social networking features that help people find each other, and tagging, which helps people filter information for relevance. There are diverse kinds of community mechanisms – only a few are listed here.
The third pattern is the simplicity of the user experience and the various interfaces by which developers can access data and capabilities. For end users, we’ve seen significant improvements in user interface design and responsiveness based on AJAX methods [Asynchronous JavaScript and XML].
For developers, lots of simple and highly scalable mechanisms have emerged, such as feeds, simple extension mechanisms, and well-behaved HTTP-based APIs. Developers are building all kinds of situational applications on top of services, remixing them in various ways, without ever having to contact the service providers. The result is a rich, decentralized, ecosystem that adds more value to the Web 2.0 businesses involved.
Slide 4
The increased emphasis on empowering individuals coincides with the arrival of a new category of software: Social software. It includes services like online marketplaces, blogs, photo sharing sites, social networking sites, community wikis, and social bookmarking services. These services have several characteristics that are very relevant as businesses look for ways to empower and connect their people.
Typically, the sites use various methods like tagging, reputations, and ratings to build a vibrant online community from the bottom, up. Recognizing that users don’t have to use their site, they are designed to attract users and make it worthwhile to participate. And its user input that creates the value of the site and makes the community work. For example, transacting in an online marketplace only works because user input is used to measure the reputations of buyers and sellers and develop trust.
Finally, these are really simple sites: they resist adding a lot of advanced features and instead focus on simplifying the user experience to reach the largest possible community.
Slide 5
Age is often overlooked when addressing the subject of employee diversity. Yet, the viewpoints and perceptions of different age groups can present significant barriers in a workforce where age differences can span 40 years or more.
For example, preconceived biases about the willingness of older workers to learn and embrace new technologies can limit their opportunities, discouraging mature workers from refreshing their skills.
At the same time, younger workers may be perceived as not willing to “pay their dues” before advancing in the company. This can dampen the enthusiasm of new employees and result in low morale and early attrition.
Slide 6
Amazon provides great examples of trust mechanisms – ways to improve the reliability of transactions.
Slide 7
The same idea easily applies to corporate content.
Slide 8
And eBay is a great example of a site that builds trust through its buyer and seller reputation mechanisms.
Slide 11
Individual bloggers have tremendous power to publish information about both personal and professional interests.
Slide 12
Declan Butler (a reporter for Nature) maps H5N1 news reports onto Google Earth, and provides regular updates on his blog.
Slide 14
Sense of community can be created various ways. wikiHow gives a nice example of a tool- or destination-oriented site – it’s based on user contributions similar to wikipedia, and it’s a mine of interesting information.
Slide 15
A Wiki is a collaboratively written web site Trivial access control: Any reader may edit anything on any page Obvious problems: vandalism, no fact-checking… Yet it works anyway. WHY?
Slide 17
Flickr is a premiere photo sharing service, with strong community features
Slide 23
“Ajax” is an acronym which stands for Asynchronous Javascript and XML. Knowing what the letters stand probably doesn’t make it any more clear, so let’s look at a graphic to see what this is all about. In the typical web application, each time you click on a link, your browser contacts a server, which sends back a whole new page. When you click on the next link, this round trip happens again, refreshing the page every time. Now you probably found that animation to be a little bit annoying, especially the 3rd time I clicked on it. Well, that’s how the web feels, and that is what Ajax is trying to fix.
An Ajax application starts off the same way, when it brings in the initial page. But after that, Javascript on the page makes background calls back to the server, and uses that new data to update only a portion of the page. This delay is much less noticeable, and therefore the application feels more responsive.
Ajax, by its very nature, requires discrete services that are well-tuned to the needs of the web page, so you can minimize processing on the client side. These might not be the services you happen to have though. It may drive requirements for new services from your IT department. Slide 24
One thing we know from all of that history is that coding Ajax is very hard. Some companies report that only 1 in 40 candidates have the necessary skills to do it, and that might even be a generous estimate. There are lots of pitfalls. The most serious ones are related to navigational state, meaning things like the back button and bookmarking. We can see a simple example of this in Google maps. If you drill down on a location, notice that the URL doesn’t change. If you want to bookmark a specific location, you need to use a special link to create the bookmark. That’s not the end of the world, but it’s not how things normally work.
In Google Maps, the Back button works very well, but in other applications you could easily lose your work by pressing the back button. This is because state is being stored in the browser, and it’s much more difficult to catch all the cases where that data might be lost.
There are more subtle issues as well. If your pages are being computed dynamically through Ajax requests, there may not be any interesting content for a search engine to index, so your Ajax pages will be harder to find.
Latency is another big issue – you can send requests out and get responses back in a different order! Performance isn’t always better; it really depends on what your application is doing. You’re basically trading off a few large requests vs. many small requests. Whether or not that tradeoff pays off depends on how much data is being transmitted and how much of the page is changing.
So if all this is true – it’s been around for a long time, it’s complex, and it might not be better, then…
Slide 28
Zillow creates transparency for real estate transactions, by showing tax values, recent sales, and for-sale properties based on a map.
Slide 31
Goal: make it likely that most tables of data have a plausible visualization.
Slide 35
Social software has several characteristics that are very relevant as businesses look for ways to empower and connect their people. Typically, the sites use various methods like tagging, reputations, and ratings to build a vibrant online community from the bottom, up. Recognizing that users don’t have to use their site, they are designed to attract users and make it worthwhile to participate, and its user input that creates the value of the site and makes the community work. For example, transacting in an online marketplace only works because user input is used to measure the reputations of buyers and sellers and develop trust.

Abstract: CASCON 2006 In the networked information economy, Open Innovation is used to describe an approach to innovation that is marked by openness, sharing and mass collaboration. Enabled by the Internet CASCON 2005 and inspired, in part, by the success of open source, companies are opening up their patent vaults, engaging in debate about re-balancing traditional practices around IP to stimulate CASCON 2004 innovation, and encouraging global participation in what were previously internal matters. Similarly, in the area of standards, which have long been used as a way of helping things work CASCON 2003 together without hindering competition, the need for open standards and interoperability of CASCON 2002 software is becoming critical as IT is increasingly part of everyday life. The Internet, built on open standards, is increasingly the platform for the delivery of a variety of services, from CASCON 2001 banking to entertainment, and importantly access to information and government services. Today, however, the end user is not only a consumer, but a citizen. As citizens, access and the CASCON 2000 ability to participate are part of the democratic process. New forms of online service delivery may be efficient and effective, but are they democratic? CASCON 1999
Open innovation is premised upon collaboration. How might an open innovation agenda help us CASCON 1998 think through and address the challenges and opportunities of living in an economy and society where the social and technical are so closely intertwined and mutually shaping? There are no Workshop reports easy answers, but with a group of experts who think deeply about these challenges and experience them in their daily practice, we"ll start the conversation. CASCON 2006
The Panel will explore questions such as: CASCON 2005
Business, government, including granting agencies, and the university, all encourage cross- CASCON 2004 sector research partnerships to stimulate innovation, while at the same time local IP regimes CASCON 2003 can be roadblocks to collaboration. Is there a way to do this better? How open can government, industry or the academy be? CASCON 2002 How open should universities, especially public universities be? How open does business need to be to meet the needs of consumers and does business have a CASCON 2001 choice in an increasingly networked economy? How open does access to government information and services need to be to meet the CASCON 2000 democratic rights of citizens? Is Open Innovation consistent with public policy and programming for research and CASCON 1999 commercialization, an approach that provides public investment for research and incentives to stimulate private investment in bringing discovery to market? CASCON 1998 Are our institutions prepared to support collaboration? Where should collaboration end and competition begin? Can these be complementary processes? Are there examples of new models?

Format: Workshop reports Hands-On CASCON 2006 Abstract: CASCON 2005 XML, a platform independent and flexible way of describing, sharing and storing data, has become a popular way of representing data for business integration and industry CASCON 2004 standardization. Traditional relational databases do not recognize XML as a first-class datatype, making it difficult or inefficient, to store and query XML data. With the introduction of DB2 9, CASCON 2003 DB2 has evolved, from being a premium relational database, into a hybrid database by allowing data to be stored, managed and queried in both XML and relational form. Starting with DB2 9, CASCON 2002 XML is a first-class datatype and hence XML documents can be stored in XML columns and manipulated like any other datatype. These XML documents are stored "natively" on disk in tree CASCON 2001 structures matching the XML data model. DB2 also provides an XML Schema repository which allows easy management of XML schemas and validation of XML documents against these CASCON 2000 schemas CASCON 1999 DB2 has extensive query support, offering both XQuery and SQL/XML options. XQuery support provides a standards-based, concise, and efficient language to extract and manipulate data CASCON 1998 from XML documents. It allows navigation within an XML document structure, based on standard XPath, to efficiently operate on the precise information of interest. Advanced XML indexing capabilities, akin to relational indexes, allow one to improve the performance of queries over XML. Index keys are created based on XML pattern expressions, allowing access not just to the document itself, but nodes within the document. Implementation of SQL/XML (XML extensions to the SQL language standard) allows one to embed XPath/XQuery in SQL and query relational and XML data at the same time. Joins between XML and relational columns and the use of XML and relational predicates provide unrestricted querying power to DB2 9 users
DB2 implements the SQL/XML publishing functions which allow one to "publish" relational data as XML. This is critical as a considerable amount of data already exists in relational form and modern applications/frameworks, such web services, B2B, and SOA, often require that data be in XML format. On the other hand, the SQL/XML XMLTable function allows one to convert data stored in native XML format into relational format for legacy applications that require relational data.
In this workshop, an overview of the XML datatype, XML schema repository, XML indexing, XQuery, and SQL/XML features in DB2 9 and upcoming DB2 9.5 will be given with hands-on exercises covering their basic functionality. At the end of this workshop, attendees will have a good understanding of what a true hybrid database is and will have experienced the powerful yet easy-to-use XML features of DB2.

CASCON 1999 WebSphere for Academics Workshop Chair(s): CASCON 1998 Ozair Sheikh IBM Workshop reports Format: CASCON 2006 Hands-On CASCON 2005 Abstract: This workshop will focus on using the IBM WebSphere DataPower SOA appliance to implement CASCON 2004 and configure security within an SOA environment. The DataPower appliance is a purpose-built network device providing rich functionality, which can be configured from a single management CASCON 2003 interface. It allows you to perform security-related tasks, such as XML Digital Signatures, XML Encryption, AAA (Authentication, Authorization, and Auditing), and XML threat protection. It also CASCON 2002 integrates with many security-based systems such as LDAP and Tivoli Federated Identity. CASCON 2001 This workshop will discuss three main topics: Web services security, AAA, and XML threat CASCON 2000 protection. CASCON 1999 Web services security is an XML-based language for ensuring end-to-end message integrity, confidentiality, and single message authentication. It is a common security language used to CASCON 1998 integrate different security implementation. The processing and generating of messages using Web services security is resource intensive, especially for application servers that process a high volume of messages. The IBM WebSphere DataPower SOA appliance can be configured to generate messages with Web services security and process them at network speed through its hardware acceleration.
The term AAA is an acronym for Authentication, Authorization, and Auditing. The IBM DataPower SOA appliance provides both on-box and off-box support for validation of credentials and exchange of security assertions. A typical enterprise may have various technologies used to validate user credentials, such as LDAP, and Tivoli Access Manager. The IBM WebSphere DataPower SOA appliance integrates with many AAA-based systems, which can be configured using the DataPower management interface. It also supports technologies used to enforce single-sign-on within an enterprise such as: SAML, XACML, and LTPA. The IBM WebSphere DataPower SOA appliance can be deployed easily within an environment to integrate various security implementations and facilitate single-sign on within an enterprise.
Enterprises use IP firewalls to protect their internal networks from external attacks. These IP Firewalls are deployed in the Demilitarized zone (DMZ), since it's the part of the network which receives the initial request from external clients. In an SOA environment, Web services are invoked using SOAP over HTTP. IP Firewalls typically allow incoming traffic through HTTP (port 80), but do not inspect the payload for any malicious content. Hackers can send malicious content into an enterprises internal network using this loophole to attack XML and Web services applications. The IBM WebSphere DataPower SOA appliance can be used to protect against XML threats. A policy can be configured to inspect incoming messages for well-known attacks. The box can also be configured to protect against single and multiple message denial of service attacks.
This workshop will demonstrate how to implement and configure the three topics discussed above using the IBM WebSphere DataPower SOA appliance. Workshop attendees will learn the security issues and how the IBM WebSphere DataPower SOA appliance can be used as a solution to these problems. This workshop will have both lecture and hand-on sessions to demonstrate the capabilities of the IBM WebSphere DataPower SOA appliance. Agenda: Full-day:
9:00am -12:00pm -IBM WebSphere DataPower SOA appliance overview -Overview of security issues and security technologies used to address these issues -IBM WebSphere DataPower support for Web services security, AAA, and XML threat protection
1:00PM - 4:00PM -Labs on Web services security, AAA, and XML threat protection

Abstract: CASCON 2006 The final program is available HERE. CASCON 2005 As computer hardware continues to dramatically improve in transistor density and raw capability, the importance of compilers to bridge the gap between high-level programming CASCON 2004 languages and these abundant hardware resources has never been greater. The workshop on Compiler-Driven Performance provides an important opportunity for academic faculty, students, CASCON 2003 and industry researchers and developers from across Canada and in the United States to meet to discuss the state-of-the-art in compiler technology as well as new innovations and future CASCON 2002 directions. CASCON 2001 The current state of computing technology motivates a number of key challenges for compilers CASCON 2000 to address. The workshop will have a particular focus on the following. CASCON 1999 (1) Innovative Analysis, Transformation, and Optimization Techniques: Today's software systems are often composed of several different languages and programming models. At the CASCON 1998 same time the underlying processors and memory systems are typically complex out-of-order superscalar processors. To manage this complexity to produce efficient systems in a way that does not increase the burden on programmers requires constant innovation in compilation methods and optimizations.
(2) Languages, Compilers, and Optimization Techniques for Multicore Processors and Other Parallel Architectures: As we approach one billion transistors on a single die, all processor vendors have switched to multicore product lines; future chips will likely contain a number of processors that doubles with each generation, soon reaching a thousand processor cores on one chip. This highly-parallel hardware represents a daunting challenge for average programmers, and compilation technology is well-suited to ease this parallel programming crisis. Potential solutions range from new languages for expressing concurrency to speculative threading and transactional memory.
(3) Compiling for Streaming or Heterogeneous Hardware: In addition to highly-parallel multiple-core processors for general-purpose and scientific computing, the computer hardware industry is also aggressively pursuing custom computing cores to accelerate key applications. Such heterogeneous computing systems were once limited to the embedded domain, but are becoming increasingly common for general-purpose computing. Examples include cores for encryption, compression, and pattern-matching, systems that have FPGA co-processors, IBM/Sony/Toshiba's CELL processor which contains multiple vector processors for media and other stream processing, and graphics processing units (GPUs) which will likely soon be incorporated on-chip with regular processors. The resulting heterogeneous hardware presents another key challenge that the community targeted by this workshop is working to address.
(4) Dynamic Compilation for High-Performance and Real-Time Environments: Of ever- increasing importance are compilers that dynamically translate or optimize programs, not only to support interpreted languages such as Java, but also to exploit the run-time behavior of programs written in C and C++ to improve efficiency and performance. Such layers of abstraction may also prove to be important for allowing programmers to efficiently target the emerging highly-parallel and heterogeneous hardware.
(5) Tools and Infrastructure for Compiler Research: The changing technology landscape highlights the need for ever-improving compiler-based tools and infrastructure for understanding programs and performing research, finding and eliminating bugs and race- conditions, and profiling for improving performance.
Agenda: The proposed workshop is an all-day multiple-speakers workshop that will tentatively run from 9am until 4pm. The workshop will consist of eight to ten talks of between twenty and twenty- five minutes each, with additional time for questions after each talk. Talks will be grouped into sessions by topic in groups of two or three talks, with either a half-hour break or lunch between sessions to provide further time for discussion and interaction.

Abstract CASCON 2000 CASCON 1999 Harvey Firestone the founder of Firestone Tires once said: Success is a sum of the details. This is true and over the past decade, software practitioners have come to realise that there must be CASCON 1998 a detailed understanding of the customer to produce: reliable software, with strong performance, in tune with the user's business processes and needs.
As a result, software development is evolving to one of profiling. A cycle where we seek to understand customer/user business processes, their technical details such as software usage context (operating system platform, version, or hardware platform and so on), and various dynamic descriptions of the developed software within an entire solution executing within its use case.
Furthermore, off-the-shelf product line software has complicated the understanding of software users because there is high heterogeneity of application execution by users. A software product line, the common consumer form of modern software, is now considered an inherent part of a solution where there is versioning within contexts such as operating systems. So creating requirements, and validating plans for UNIX does not validate it for Linux, and creating requirements and validating it for the Vendor A version of Linux does not validate it and define its requirements for the Vendor B version of Linux.
As an organization, IBM prioritizes customer focus, process, the human side of quality, and measurement and analysis as part of a market driven quality strategy. Because of this focus, several initiatives are providing an understanding of the customer from the inside out. Such work includes profile-based testing strategies in DB2 which focuses on quality with validation priorities in mind across a complex product line; Autonomic Computing and performance analysis in Tivoli and other IBM solutions that focus on building computing systems have the ability to manage themselves. The intention is to adapt dynamically to change in accordance with business policies and objectives, enabling computers to identify and correct problems often before IT personnel notice them. Outside In Design focuses on understanding customer and user goals within the context of IBM business goals and creating clear and concise documentation that informs and facilitates design and implementation that continually keeps the user in mind. And the final example is the Balanced Configuration Unit in DB2 which was created specifically for business intelligence customers in a preconfigured block of hardware and software combinations designed to function as a single unit and tuned for maximum BI and data warehouse performance. This an example of a product built with measured knowledge of what works.
This workshop will bring together the best of breed practitioners in this new area of user-based software development with expertise in Profile-based Quality, Autonomic Computing, Outside- In-Design and other areas. These will be the experts who dive daily into the details of customer business processes, and use them to inform planning, requirements, design, development, quality assurance and quality control of software. The practitioners will share their experiences of what works in understanding, capturing, and using the needs of the technology customer to drive a "silver bullet" user-based methodology to developing, maintaining and optimizing software solutions. These are experiences where there is such a strong understanding of the customer's business processes that customer satisfaction is truly the number one priority. The goal of the workshop is to select and document the silver bullet user-based methodology to achieve on time, on requirements, and on quality software, based on detailed user knowledge. The workshop will also extract the business benefits of this approach.
We also invite researchers in requirements, software process, software quality management and the management of technology to attend and contribute based on the most current research work in user focused software development.

Abstract
This presentation will explore the essentials of a profile-based quality assurance (QA) strategy. We base our approach on the collection of customer usage metrics that flow from IBM's focus on quality, process and measurement.
We will discuss the overall strategy, which will include reuse and update of profiles for software in heterogeneous environmenets for diverse users. We will also discuss how DB2 facilitates this approach by providing instrumentation and internal execution monitors.
We will also look at the benefits that occur when a profile based QA strategy is implemented and present the gains we have made in quality with this program over the years. Finally, we will present the assessment of value for profiling for any widely distributed software.

CASCON 2002 Abstract: In recent years, hardware and software have become commodity-like, with a substantial CASCON 2001 portion of their production having moved out of North America and Europe. At the same time, Canada, the United States, and other developed countries have economies that are CASCON 2000 predominantly service based. Institutions of higher education must revise their curriculum in response to this rapidly changing landscape. Several leading universities have already CASCON 1999 introduced such new curriculum, or are in the process of doing so. The purpose of this workshop will be to bring together leaders from industry, government, and academia, in order CASCON 1998 to understand the state of the art in SSME curriculum development, assess the extent to which this new curriculum addresses industry and government needs, and come up with recommendations regarding future efforts in this area.
Some key questions for discussion are the following: 1. What are the different models for delivering SSME education? At undergraduate, graduate, or doctoral levels? At Computer Science, Engineering, Management, or Social Science schools? Or as a very trans-disciplinary program? As certificate, diploma, or degree programs?
2. What is the relationship between the SSME curriculum and SSME research? That is, what is the extent to which an SSME research program or center needs to be in place to complement the curriculum? 3. What are the different models for having industrial and government partners involved in curriculum development, marketing, and delivery? 4. What really is the job market for those with SSME training? And what are core competencies we want our students? At a minimum, is there a service science competency?
Goals: At the end of the workshop, we will produce a report that summarizes the following results: Curriculum repository Strategies for creating / leveraging communities of people / schools teaching this Minimum competency / set of skills (regardless of discipline) for service science education Plan for the next workshop / meeting / next steps
Agenda: 1pm to 3pm: Four speakers each present for 30 min 3pm to 3:15pm: Break 3:15 to 4:30pm Panel addresses the following questions: 1. What are the different models for delivering SSME education?

Abstract
Growing Service-minded Thinkers
In the United States, over 70% of the labor force is engaged in services, and an estimated 75% of the GDP in 2005 was derived from services. Industrialized countries around the world share similar statistics, while emerging economic powers, such as India and China, are seeing dramatic growth in their services economy. The service sector has evolved from a low-skill, labor-based position to one where high-skill professional services, particularly business-to- business services, are a leading driver of innovation, accelerated business globalization and economic disruption. This rapid shift, however, due to the complex and inter-disciplinary nature of service system design, deployment, support and evolution, has resulted in a gap between the practice, definition and science of service systems. This summary will provide evidence of the shifting economy and examples of university programs that are adopting and assimilating service thinking, learning and research into their curriculum.

Abstract
SSME Curriculum: Objectives and Plans
In response to The change of emphasis in the economy, from agriculture and manufacturing to service, a new academic discipline, Service Sciences, Management, and Engineering (SSME), was created. This new discipline should incorporate existing knowledge in science, technology, management, and engineering, and create new techniques, in order to design scientific methods for increasing productivity, for making services more efficient, and service planning more systematic. Curriculum in this new discipline is being developed, in order to train the service workforce.
This talk will include an analysis of the objectives of SSME curriculum and how those objectives can be met, a survey of existing SSME curriculum, and an outline of plans for future curriculum development.
In addition, the talk will include criteria for assessment of SSME curriculum. Those criteria may be used in order to determine the contribution of the curriculum to training the service workforce.

Abstract
Developing a Pan-Faculty Graduate Certificate Program in Service Science The difficulty of developing a curriculum in Service Science is that there are many disciplines from which to draw. Furthermore, it is more challenging to design a Service Science curriculum at the graduate level than the undergraduate level because there are four years worth of courses during the latter. A pragmatic approach we are investigating at York University is to complement a standard graduate education with courses to build service science competency. A natural possibility is the design of a certificate program in service science, which students in Business, Computer Science, or Engineering may earn by taking extra courses in conjunction with their degrees. As an example, the Financial Engineering certificate program at York, available to Master's students in Business and Math, represents a template for a similar program in Service Science. In this presentation, I will discuss the framework for this Service Science certificate program, including a discussion of the pragmatic trade-off that must be made in developing a certificate program that can be promptly and unobstrusively installed to fit with the curricula of several disparate faculties, but at the same time still provides substantive Service Science training for students.

WebSphere for Academics CASCON 2006 Format: CASCON 2005 Multiple speakers CASCON 2004 Abstract: At the heart of every business is a complicated web of processes that form the foundation for CASCON 2003 all operations. Since these business processes play such a central role, they must be efficient to make the business effective. As a result, finding ways to automate and improve business CASCON 2002 processes has become a major focus for today's organizations as they struggle to find ways to become more agile and responsive to changing business climates. CASCON 2001
Business process management (BPM) solutions encompass methods, techniques and tools to CASCON 2000 create, analyze, manage and optimize operational business processes involving humans, CASCON 1999 organizations, applications, documents and other sources of information. To enable business agility, business process management is based on the principles of services-oriented CASCON 1998 architecture (SOA) and offers an environment that improves other traditional methods for altering an application to reflect changing business rules or processes. Through intuitive, visual interfaces, an effective BPM environment offers business managers ways to change rules and alter processes without having to drop down to the code.
This workshop will give an overview of BPM through a series of presentations.

CASCON 1998 Christopher Anand McMaster University Yelena Yesha University of Maryland Baltimore County Workshop reports Milton Halem University of Maryland Baltimore County CASCON 2006 Format: CASCON 2005 Multiple speakers CASCON 2004 Abstract: As the scaling of CMOS chip processing technology reaches the limits of power and heat CASCON 2003 constraints, the micro-processing industry has shifted to the development of multicore processors. These chip architectures contain independent processors integrated on a single chip CASCON 2002 with either shared or independent cache memories. This shift places the burden of achieving scalable performance on the software implementation of highly efficient parallel programming. CASCON 2001 CASCON 2000 This workshop will consist of an introduction to the Cell BE processor, and a number of presentations/demos of compilation, analysis, tuning and visualization tools for Cell BE, as well CASCON 1999 as research applications, specifically of the Cell BE processor architecture, to the solution of science and engineering problems with a focus on but not limited to the areas of aerospace, CASCON 1998 environmental/geosciences, space science, astrophysics, defense, medical imaging and bioinformatics.
Presentations are solicited concerning the development of new tools or the adaptation of existing tools to heterogeneous multi-core computing in general and the Cell BE in particular. Analyses of the failure of conventional tools to make efficient use of heterogeneous multi-core architectures are also solicited. For example, patterns of parallelism which cannot be implemented by a compiler back end because there is no reasonable way for the compiler to determine the safety of a required code transformation.
Application presentations in the following areas are solicited:
(1) Any S&E performance evaluations and/or research in progress of application codes which leverage the capabilities of the Cell BE in the above focused areas;
(2) analyses of different parallel programming design approaches applied to the S&E applications (e.g. strategies for parallelization or software branch prediction) in the context of Cell BE utilization;
(3) Code run implementation demonstrations, including visualizations and animations;
(4) summaries of existing results and future Cell BE research directions as well as the practical/theoretical barriers faced in applying these problems on heterogeneous Cell BE architectures.
(5) application of Cell BE architectures to real-time data-driven systems.
At the end of Part 1 of the workshop, the organizers will propose a Cell BE programming challenge, for which participants will be invited to submit solutions after the workshop. The solutions will be benchmarked by the organizers and the results made available on the Web. This is not a contest in the sense that there is no prize, but participants are welcome to brag about the performance of their solution! Part 2 of the workshop will include a panel discussion of multicore processing in general.
Agenda: Part 1 will have 5 40-minute talks (each with 10 minutes for questions) followed by the presentation of the programming challenge problem.

Robert Enenkel IBM Toronto Lab Robert will start things off with an introduction to CELL hardware architecture, and the tools available in the SDK and from IBM for generating and debugging code on the CELL. This is not a crash course, but an overview sufficient for software professionals new to CELL to understand the performance potential, and the hardware and software issues which must be understood to plan software development on CELL.
Abstract
Robert received his B.S., M.S., and Ph.D. degrees from the University of Toronto, with thesis work in the area of numerical methods for the parallel solution of initial value problems for ordinary differential equations. He currently belongs to the optimizing compiler group at the IBM Toronto Laboratory, and was previously a Research Associate at the IBM Centre for Advanced Studies (CAS). Prior to joining CAS, he worked at IBM on the development of a C compiler and its math library, and developed parallel methods for random- number generation for Fortran and high-performance Fortran compilers.
Robert currently performs research and development in numerical computing as it relates to compilers and operating systems, including floating-point arithmetic, mathematical function libraries, and the performance tuning of algorithms. He is also interested in parallel computing and the application of numerical methods to practical problems in various areas of science. He has received several IBM Invention Achievement Awards and Author Recognition Awards.
Christopher Anand McMaster University Having developed high-performance image reconstruction software for commercial magnetic resonance imagers, Christopher has more experience than he will readily admit, of the software quality issues which arise out of the semantic gap between mathematical algorithm descriptions, and high- performance implementations. He is trying to fill that gap, one formal description of a former performance hack at a time.
Abstract
Christopher will talk about lessons learned on the way to developing a efficient elementary math library for CELL SPUs, and describe some of the tools and algorithms developed to get there.

Abstract
Recently, networked and cluster computation have become very popular and with the advent of multi-core chips such as the IBM Cell Broadband Engine (CBE) processor and the AMD and Intel multi-core processors, the need for easily written parallel programs has come to the common PC and game consoles. This presentation will introduce a C based parallel language for architecture-adaptive programming, aCe C. The primary purpose of aCe (architecture-adaptive computing environment) is to encourage programmers to implement applications on parallel architectures by providing them the assurance that future architectures will be able to run their applications with a minimum of modification. A secondary purpose is to encourage computer architects to develop new types of architectures by providing an easily implemented software development and runtime environment and a library of test applications. This language should also be an ideal tool to teach parallel programming. aCe has been implemented on the MasPar MP-1 and MP-2, the Cray T3D and T3E, SGI NOW, single processors, and the Convex Exemplar. Currently, it is only supported under LINUX on single processors, SMP processors and cluster of processors (Beowulf). We at UMBC plan to implement aCe for the IBM CBE and clusters of CBEs.

Abstract
Optimizing memory access patterns for the FXDECON Algorithm on the Cell BE.
Seismic data processing is widely seen as an early application of the Cell BE because of the near universal use of 32-bit data in seismic data processing and the relatively easy parallelization of many data processing algorithms.
The FXDECON predictive noise reduction algorithm presents implementational challenges in terms of both memory access patterns as well as taking advantage of a single instruction, multiple data (SIMD) instruction set for the Cell BE. The seismic data are converted into the frequency domain by performing a one-dimensional fast Fourier transform (FFT) on each trace. Cell implementations of the FFT for seismic data typically involve performing an FFT on 4 traces at once [2]. Once the FFT has been done, each frequency can be filtered independently, so the ideal way to use a SIMD paradigm is to filter 4 frequencies simultaneously. This requires the data to be reshuffled in order to achieve optimal performance on the Cell BE.
In this talk we investigate the effectiveness of memory access patterns relative to the theoretical memory bandwidth of the Cell BE. We also plan to investigate the effectiveness of hiding the reshuffling of the data in the SPEs dual pipeline and/or dedicating one or more SPEs to reshuffling the data for optimal use of the SIMD instruction set.

He has focused his research on simulations of compressible flows in astrophysics, studying problems in star formation, supersonic jet propagation, convection in stars, and astrophysical turbulence. After working 11 years at the Lawrence Livermore National Laboratory over the period from 1968 to 1985, he joined the University of Minnesota faculty in 1985 as a Minnesota Supercomputer Institute Fellow in the department of astronomy. He was Director of Graphics and Visualization at the University's Army High Performance Computing Research Center from 1990 to 1995, and founded the University.s Laboratory for Computational Science & Engineering (LCSE), which he directs, and which is now part of the University's Digital Technology Center. In 1994, in collaboration with Silicon Graphics, his team developed the PowerWall visualization system, and the first PowerWall system was installed at the LCSE in 1995. The LCSE concentrates on high performance parallel computation and the data analysis and visualization that this requires. Woodward received the IEEE.s Sidney Fernbach award in large-scale computing in 1995 and, with 12 collaborators at Livermore, Minnesota, and IBM, received the Gordon Bell prize in the performance category in 1999.
Abstract
The Cell processor offers a very large potential performance boost for scientific simulation codes. To realize this potential benefit, however, these codes must be restructured so that their local memory workspaces are made extremely small and their use of vector arithmetic is also enhanced. We have presented one technique by means of a single example through which this can be accomplished. This technique, which involves a massive fusion of what are normally programmed as distinct phases of computation or distinct subroutines containing many distinct loops, can be applied quite broadly. It can also be automated in a precompiler tool. The necessary code restructuring and transformation for Cell proves to be worth the trouble even on standard CPUs, where in our experience with PPM it delivers a performance boost of from 50% to 100%, depending upon the particular CPU. When parallelized on the Cray XT3, we find that this technique, due to its special data structure, reduces our parallel overhead, so that our PPM gas dynamics application speeds up by an overall factor of about 3 on this machine, and it then scales linearly to 4104 CPU cores, achieving 9.5 Tflop/s performance with 32-bit arithmetic.

CASCON 2002 Abstract: Understanding software engineering issues for autonomic computing CASCON 2001 systems is critical for the software and information technology sectors, which are continually challenged to reduce the complexity of CASCON 2000 their systems. An autonomic system knows itself as well as its boundaries and its environment, configures and reconfigures itself, CASCON 1999 continually optimizes itself, recovers or heals from malfunction, protects itself, and functions in a heterogeneous world, while keeping CASCON 1998 its complexity hidden from the user.
While there are several workshops that deal with autonomic computing systems, there are few workshops that focus on the whole life cycle; i.e., how do we design, build, deploy, operate and evolve such software systems so that they can meet given, and evolving, requirements for particular classes of users and/or applications. Most existing systems cannot be re-designed and re-developed from scratch to incorporate autonomic capabilities. Rather self-management capabilities have to be added gradually and incrementally, one aspect at a time. With the proliferation of autonomic applications, users will impose ever more demands with respect to functional and non-functional requirements for autonomicity.
The goal of this workshop is to exchange opinions, advance ideas, and discuss preliminary results among researchers and practitioners who investigate concepts, methodologies, and tools to design and evolve autonomic software.

Abstract
Failure of enterprise software systems is costly. To ensure high availability, failures must be detected, diagnosed, and fixed rapidly. Today, failures are reported late, often by customers; problem resolution is typically manual. Different approaches have been proposed to perform automated failure detection, fault diagnosis, and resolution. A symptom-based approach defines rules that correspond to failures. When monitoring, observed data are matched against a symptom catalog. While it is possible to detect some failures with simple rules, many simple failures, and most complex ones, cannot be detected with this approach. For example, a CPU hog is not easily detected by log records, and simple rules over management metrics would be tricky to devise for such a case. By contrast, an anomaly-detection approach consists of building a model of normal behaviour of the system. When monitoring, this model is applied to observed data to detect deviation. This approach obviates the need to define rules, but its results can be hard for administrators to interpret. In this work we show how to evolve symptoms such that self-healing systems can take advantage of both approaches, enabling faster resolution of a wider range of common failures.
Chen Wenguang Tsinghua University
Abstract
We present a methodology for detecting and diagnosing failures in distributed systems by analyzing execution paths. We presume that the number of invalid or abnormal paths in distributed applications is limited. With proper automatic analysis of similar paths, the sensitivity of the tool can scale to find production problems efficiently. So it is practical and necessary to analyze suspicious paths online with state-based classifiers rather than statistically. So that developers can understand the relevance of suspicious paths, statistics are still useful and provided. To make this approach practical, we propose a state machine model in which each execution path is represented as a state sequence. For scalability, each state of the state machine is distributed across the system. We also propose approaches to group similar paths to reduce the number of states by appropriate discrimination selected by the user. We define pattern recognition mechanisms to increase sensitivity over previous approaches and to control discrimination without causing state space explosion. Experiments on AdventureBuilder, a distributed application with both JMS and WebServices, show that our approach could effectively reveal many type of errors in distributed applications with low overhead.
Olivia Das Ryerson University
Abstract
To achieve high availability, an autonomic distributed system reconfigures itself (without human intervention) under hardware and software failure conditions. Self configuration is trigerred by the management components monitoring the system for occurrence of failures. The success of self configuration is highly dependent on the availability of the management components and their interconnections. This paper describes a fault tree model to evaluate the availability of a client-server autonomic system that considers the failures of management components. The model predictions will guide the selection and placement of the management components to meet the service-level availability requirements at substantially lower cost and time.

Abstract
The goal of self-adaptive software is the ability of dynamically adjusting in response to changes in the context or the system itself. This research focuses on how service variability using dynamic component switching can be used by an adaptive system to reconfigure itself as a reaction to context changes. In order to demonstrate this, we have built a "News Website System" which provides a number of services like viewing news, weather conditions, stock information and searching. When the system is operating within its normal load limits, all of the above mentioned services are provided. However, when the system is under a heavy request load, it begins a gradual degradation of the offered services. To accomplish this task, the system contains components with multiple implementations, each optimized for a particular workload. The run-time environment has been augmented with a centralized mechanism for monitoring the end-to-end system properties such as response time and throughput. Also a decentralized mechanism has been designed and incorporated for deciding and effecting processes.
Anne Kayem Queen's University
Abstract
Self-protection is a key property of autonomic computing systems that researchers have only begun to study. The problem of designing adaptive key management schemes for access control is addressed. We explain why standard key management schemes are unable to efficiently adjust to dynamic scenarios and we present a possible solution to the problem by drawing on the paradigm of autonomic computing. The approach we propose uses a stochastic model supported by data replication to preemptively adjust the resources (in this case, cryptographic keys and encrypted data) to handle varying scenarios in a seamless manner.

CASCON 2003 Abstract: IBM Websphere Business Modeler is a business process modeling and simulation tool that is the CASCON 2002 foundation for SOA. It helps organizations to identify and eliminate redundancies and bottlenecks, to reduce risk by gaining an understanding of process impacts prior to CASCON 2001 implementation, to visualize actual process performance against key performance indicators, and to pinpoint future process improvements. A process modeling and simulation tool is a CASCON 2000 technology for business analysts, developers, and I/T specialists to model, validate, simulate and analyze their complex business processes. It allows each individual teams within the CASCON 1999 organization to see the entire system functioning as a whole, providing the teams with an understanding of the synergism of the total process. CASCON 1998
Understanding the entire business model as a whole can help companies analyze their systems and develop process improvement plans. These business processes should continuously cope with and change according to both internal conditions and external environments. Traditional tools such as flow-charting, cause-and-effect diagrams, Pareto charts, and histograms are highly effective, solid methodologies for analyzing systems. However, they are only a static snapshot of a certain problem. A flowchart can be used to illustrate the complexity of a system and to simplify the process, but they provide no feedback about the dynamics of the flow. Pareto charts and histograms tie data to the process but they do not consider the constantly changing condition around the data point collected. Simulation, on the other hand, allows the team to understand the flow of the system in a dynamic environment, and illustrates the random occurrences that control it, such as downtime, human factors, and customer demands.
Simulation serves as a pre-analysis required to anticipate bottlenecks and possible errors before actual deployment. At the same time, a post-analysis to collect execution results is needed to monitor process performance. The post analysis acts as a feedback loop to the simulation process as a cue to identify the barriers and improvement opportunities for redesigning business process.
IBM Websphere Business Modeler is a process modeling and simulation tool based on the ECLIPSE development environment. The presentation will be a demonstration using Websphere Business Modeler to simulate and analyze an example of a complex business model, and to generate Business Process Execution Language (BPEL) from the business model that can then be deployed on Websphere Process Server.
Agenda: The workshop is divided into three labs. The first lab focuses on (1) importing an existing model to WBM and (2) creating a new model in WBM. The second lab focuses on annotating the processes created in Lab 1 by adding resources, processing times, and costs. Users will simulate and analyze these annotated processes. The third lab focuses on business process optimization, analyzing the current and future states of these processes to determine an optimal combination of model attributes to reach an objective. E.g. determine optimal number of resources needed to minimize average process duration in a business process.

Abstract: In 2003 IBM CEO Sam Palmisano told the Council of Competitiveness that "Innovation occurs at the intersection of invention and insight. It's about the application of invention – the fusion of new developments and new approaches to solve problems."
One of the driving motivators for innovation in our industry is the increasing commoditization of technology. As technology commoditizes, only the innovators prevail, either by creating unique technology or by achieving greater economies of scale in the production of commoditized components. Many companies are being forced to reinvent themselves just to survive! Innovation has the power to distinguish products, transform business processes, globalize markets, and benefit society. Innovative individuals will be the driving force of successful companies.
This half day workshop will explore the importance of innovation and invention in the software industry, how to foster it, and the greatest obstacles to achieving it. The workshop includes presentations from notable innovators and business leaders who will present their thoughts and personal experiences on innovation, followed by a panel discussion. The discussion panel will include a series of pre-defined questions as well as an open forum for questions and answers.
Main topics of discussion:
How to foster innovation: - Research Partnerships - Advanced Technology teams - University-industry relationships, CAS - Diversity - Training (to be innovative)
Challenges to innovation: - Product focus - Schedule focus - Funding constraints - Cultural limitations - Skill - Commitment to success (innovation incurs risk) - etc
How to manage innovation: - Joint Programs Model - Exploratory vs. Applied Research - Clients as Partners in Innovation - Culture of Innovation - etc
Attendance is open to anyone although only attendees will be treated to a fast paced discussion of one of the most important topics of our time.

CASCON 1998 Christopher Anand McMaster University Yelena Yesha University of Maryland Baltimore County Workshop reports Milton Halem University of Maryland Baltimore County CASCON 2006 Format: CASCON 2005 Multiple speakers and panel discussion. CASCON 2004 Abstract: As the scaling of CMOS chip processing technology reaches the limits of power and heat CASCON 2003 constraints, the micro-processing industry has shifted to the development of multicore processors. These chip architectures contain independent processors integrated on a single chip CASCON 2002 with either shared or independent cache memories. This shift places the burden of achieving scalable performance on the software implementation of highly efficient parallel programming. CASCON 2001 CASCON 2000 This workshop will consist of an introduction to the Cell BE processor, and a number of presentations/demos of compilation, analysis, tuning and visualization tools for Cell BE, as well CASCON 1999 as research applications, specifically of the Cell BE processor architecture, to the solution of science and engineering problems with a focus on but not limited to the areas of aerospace, CASCON 1998 environmental/geosciences, space science, astrophysics, defense, medical imaging and bioinformatics.
Presentations are solicited concerning the development of new tools or the adaptation of existing tools to heterogeneous multi-core computing in general and the Cell BE in particular. Analyses of the failure of conventional tools to make efficient use of heterogeneous multi-core architectures are also solicited. For example, patterns of parallelism which cannot be implemented by a compiler back end because there is no reasonable way for the compiler to determine the safety of a required code transformation.
Application presentations in the following areas are solicited:
(1) Any S&E performance evaluations and/or research in progress of application codes which leverage the capabilities of the Cell BE in the above focused areas;
(2) analyses of different parallel programming design approaches applied to the S&E applications (e.g. strategies for parallelization or software branch prediction) in the context of Cell BE utilization;
(3) Code run implementation demonstrations, including visualizations and animations;
(4) summaries of existing results and future Cell BE research directions as well as the practical/theoretical barriers faced in applying these problems on heterogeneous Cell BE architectures.
(5) application of Cell BE architectures to real-time data-driven systems.
At the end of Part 1 of the workshop, the organizers will propose a Cell BE programming challenge, for which participants will be invited to submit solutions after the workshop. The solutions will be benchmarked by the organizers and the results made available on the Web. This is not a contest in the sense that there is no prize, but participants are welcome to brag about the performance of their solution! Part 2 of the workshop will include a panel discussion of multicore processing in general.
Agenda: Part 2 will have 4 40-minute talks (each with 10 minutes for questions) followed by 50-minute panel discussion.

Abstract
This talk will describe the GA-CELL project which aims to develop a reusable genetic algorithms (GA) library for the Cell BE processor. GA are widely used to optimize functions where gradient decent methods are not suitable. Concepts from natural evolution are used to guide a stochastic search of the solution space. Since each iteration of the algorithm requires the evaluation of several candidate solutions in parallel, GA are highly suitable for implementation on the Cell BE. The majority of the CELL-GA library operates on the PPE where generations of candidate solutions are created and evolved, while the far more computationally expensive job of evaluating candidate solutions is left to a user-defined application-specific fitness function that runs solely on the SPEs. As part of the GA-CELL project, a sample fitness function is provided that optimizes a linear discriminant over a multidimensional data set. Evaluation of this sample project using a dual-Cell blade server shows excellent performance that scales well with the number of available SPEs. GA-CELL is an open source project available via SourceForge (https://sourceforge.net/projects/ga-cbe/).

Abstract
The multi-core Cell BE architecture has the potential to deliver extremely high performance computation to many applications. However, this processor requires parallel programming on several levels and uses a memory model that requires explicit scheduling of memory transfers.
The RapidMind Development Platform provides a mechanism for programming the Cell BE at a high level from a single-threaded C++ program while taking advantage of all nine cores available in the Cell BE processor. This system uses a unique interface that enables user-directed dynamic code generation for the synergistic processor elements on the Cell BE while eliminating the overhead of C++.

Abstract
Matrix intensive geophysics on the Cell BE.
The Cell processor coming with Sony Play Station 3 is initially designed for game applications and media-rich consumer- electronics devices, which makes the Cell processor the perfect platform for the compute-intensive and data-rich problems. It has one Power Processor Element (PPE) dedicated to control- intensive tasks like operating system, while eight Synergistic Processor Elements (SPE) dedicated to compute-intensive tasks. As a result, developers in Geophysics can grab this huge amount of horse power to solve their compute- intensive problems running in parallel, achieving order-of-magnitude improvement in peak computational performance and area-and- power efficiency over conventional PC processors. To harness these SPE.s we transform the algorithms into matrix based methods. We deal with the seismic inverse problem with the Cell processor and compare the performance result with the one gained from conventional PC processors.

Abstract
Applying the IBM CELL Technology to Climate and Weather models---Lessons Learned in Porting the Solar Radiation Code This talk describes our experiences in porting the solar radiation component of the NASA Goddard Earth Observing System Model, GEOS-5, which has been used in various climate and weather models. This component is very computation-intensive, ~25% of the computing time of GEOS-5 with a small input/ output requirement, which is well suited for another, CELL, characteristic, high ratio of computation to data payload. In addition, this component consists of independent calculations along the vertical direction, so- called embarrassingly parallel.
We have developed a prototype to experiment with the CELL BE DMA to transfer data between the driver of solar radiation code in the PPU and the routines of solar radiation code in SPUs and succeeded in transfer one-, two-, three-dimensional arrays between the PPU and 8 SPUs. Currently, we are implementing DMA into the solar radiation and will report the progress in vectorization and performance measurement.

Abstract: CASCON 2003 This workshop will address significant challenges that are being faced by people implementing SOA. Although Service-Oriented Architecture (SOA) is having a significant impact on the way CASCON 2002 software systems are developed, evolve and are maintained, there is currently significant confusion on exactly what SOA is, how to implement SOA, and what is unique about SOA. The CASCON 2001 multitude of vendor offerings, as well as diverse and sometimes competing standards for SOA implementation, have contributed to the confusion. CASCON 2000 CASCON 1999 The workshop will begin by presenting an SOA research agenda that has been developed over the past year through an SEI independent research and development project. The workshop will CASCON 1998 present the open research topics grouped in terms of engineering, business, operations, and cross-cutting concerns. A discussion will be held on the framework to suggest gaps and next steps. The focus will be on topics of most concern to users of SOA-based systems, SOA infrastructure, and services. The goal is to develop a list of critical unmet needs of this community of practitioners.
The talks will focus on areas that have an impact on SOA adoption from a user perspective, such as: - Strategic implementation of SOA - Alignment between business models and service models - ROI for SOA adoption - SOA Governance - SOA Development Life Cycle - Service-Level Agreements in the Context of SOA - Service Usability - Instrumentation. Monitoring and Logging in SOA Environments

Abstract
This talk will present a set of SOA research challenges organized around engineering, business, and operations, as well as cross-cutting concerns that include such issues as monitoring and adoption. Each of these areas are subdivided into sub-areas. For example, engineering is organized around the main aspects of the service-oriented lifecycle, such as service selection, service definition and architecture and design. A series of crucial challenges are identified such as how does lifecycle change in a service oriented environment with specific sets of characteristics, how is the most appropriate service selected, and what are techniques to ease the deployment of services in heterogeneous platforms.

Are you working on a software product, and wondering how you could possibly know how it should integrate with other CASCON 2003 products? Have you heard the term "Green Thread", and are wondering what it means? This workshop could be for you. CASCON 2002
Many companies, including IBM, build a large selection of individual, standalone products. CASCON 2001 However, we know that customers use these products in combination with others -- whether from the same or different companies -- integrating them into a solution. Unfortunately, these CASCON 2000 solutions often lack real integration between the products, leading to workarounds, service CASCON 1999 engagements, and dissatisfaction. CASCON 1998 In IBM Rational, we recognized the need to improve how our products work together, as well as with other key IBM products, and the importance of addressing this issue for our customers.
This workshop will discuss the approaches we are taking to improve product integrations, including: - Green Threads. This methodology uses customer-based scenarios to identify opportunities to improve our products and cross-product integrations. With detailed customer examples and simulated environment, we have successfully driven new requirements into our products, and begun to change how such requirements are evaluated. - Testing Cross-Product Integrations. In addition to the Green Thread scenarios, our System Verification Test team uses other approaches to ensure products work together as they should. Casting a wider net than the Green Threads, to cover a variety of potential scenarios, this team has also realized successes in improving product integration.
This workshop will describe how we are applying each of the approaches, our challenges, and our successes so far. We will discuss these topics from both the solution and the product perspective.
We want to hear your ideas too! Following the presentations, we will facilitate an open discussion around these approaches as well as the general issue of product integration, with the goal of identifying, sharing, and promoting best practices in this area.
Agenda: Introduction (15 mins) Rational Green Threads: Motivation & Methodology (60 mins) SVT: Executing Integration Scenarios (45 mins) Product Perspectives: UI Integration Challenges (45 mins) Discussion (45 mins)

Abstract
SVT: Executing Integration Scenarios Managing the multitude of integrations across products is a challenge that is further complicated by numerous and overlapping release schedules. Ensuring comprehensive test coverage and enabling teams to be proactive in identifying and addressing gaps in the product release plan requires a coordinated effort that is supported by tooling and a well documented process. This session will describe the approach taken by SVT to identify, prioritize, and catalog integrations derived from the green threads; the method we use to capture integration requirements and provide traceability to test cases; and tooling used to monitor and report on test coverage across multiple teams. We will also present some of the successes of the integration effort and the challenges we have faced.

Abstract
User Interface (UI) Integration Challenges Although the functionality that an application provides to users is important, the way in which it provides that functionality is just as important. At the product level, there are significant challenges to provide seamless integration at the UI. We will describe two techniques – storyboarding and milestone assessment – to design and ensure better UI integration for products, drawing on information and requirements from cross-product Green Threads.

Abstract: CASCON 2004 For over 40 years the Mainframe has withstood the test of time as the premier transaction processing platform serving as the backbone of our economy and driving industries such as CASCON 2003 Financial, Transportation, Retail, Government and Academia. While its reputation has perceived it over all those decades little is known about the secrets of its success outside of the world of CASCON 2002 raised floors and corporate boardrooms. CASCON 2001 To put it simply both the hardware and software that make up the modern mainframe have been optimized to handle large scale transaction processing and database serving. What is CASCON 2000 interesting to note here is that this type of workload does not have to be confided to moving CASCON 1999 money between accounts since any workload that mimics transaction processing will in turn be optimized to run on the mainframe. CASCON 1998 Over the last few years IBM has been working with post-secondary institutions throughout the world to reintroduce the mainframe curriculum via its Academic Initiative program. The success in Canada with our academic partners has started to generate numerous questions about possibilities of using mainframes in research. Being a commercial platform it is uncommon to see them on campuses used to perfect the next communication protocol or develop clustering technologies or even play games with; but these ideas are exactly what this workshop has been designed to introduce.
Many technologies that we take for granted today have been invented originally for the mainframe such as virtualization for example. Many problems that researches in computing fields are trying to solve today have already been solved on the mainframe such as workload management for example. This is where the discussion starts.
The audience will be given a crash course in what makes a mainframe tick from underlining hardware design to highly optimized operating systems and applications all the way to near instantaneous recovery capabilities via proprietary star-based clustering technology.
What will follow is the context in which these systems operate in, such as where and how they are deployed, who uses them and why, as well as where they are heading in the future. This part will also include strong historical background to anchor further discussion in platform's importance and its longevity.
After the break the discussion will turn toward academic engagement, looking at successes in reintroducing mainframe curriculum into Ontario's post-secondary system and how it's been received from school administrators, students and the industry.
The final presentation will focus on ways the mainframe can be utilized in research and development. The key here will be to connect the capabilities of the platform with the needs of the research community and showcase where and how they meet. Special emphasis will be placed on security, virtualization, workload management, clustering, offload processing, I/O optimization and of course gaming. Unknown to the vast majority of the population, the mainframe has recently gained specialized abilities which allow it to host massive online gaming environments.
While the workshop will be open for questions throughout, time will be provided at the end for an open discussion on any of the topics raised. Using mainframes in R&D is a new territory and as such will require a lot of original ideas to get started. This workshop is intended to introduce the platform to the Ontario's research community and seek your guidance as members of that community as to its direction going forward.

An autonomic system knows itself as well as its boundaries and its environment, configures and reconfigures itself, CASCON 1999 continually optimizes itself, recovers or heals from malfunction, protects itself, and functions in a heterogeneous world, while keeping CASCON 1998 its complexity hidden from the user.
While there are several workshops that deal with autonomic computing systems, there are few workshops that focus on the whole life cycle; i.e., how do we design, build, deploy, operate and evolve such software systems so that they can meet given, and evolving, requirements for particular classes of users and/or applications. Most existing systems cannot be re-designed and re-developed from scratch to incorporate autonomic capabilities. Rather self-management capabilities have to be added gradually and incrementally, one aspect at a time. With the proliferation of autonomic applications, users will impose ever more demands with respect to functional and non-functional requirements for autonomicity.
The goal of this workshop is to exchange opinions, advance ideas, and discuss preliminary results among researchers and practitioners who investigate concepts, methodologies, and tools to design and evolve autonomic software.

Baoning Niu Queen's University Abstract
One of the desirable properties of self-managing DBMSs is the ability to manage workloads based on their importance to business. This calls for mechanisms that allow self-managing DBMSs to be able to translate the workload importance into resource allocation plans. This paper introduces a framework for this mapping. Workload impor-tance is encapsulated into an objective function that is optimized to derive resource allocation plans. A process with a general form of workload utility functions is developed for simplifying the job of quantifying workload importance.

Abstract
WS-Policy4MASC is our XML language for specification of policies for run-time Web service management. Among its original contributions are specification of diverse business values (benefits/costs, tangible/intangible, agreed/possible, absolute/relative) and specification of various control strategies maximizing different business values (e.g., only agreed intangible benefits). It was originally developed for the MASC (Manageable and Adaptable Service Compositions) middleware. However, we envision that it can be used in a broader context of autonomic computing, because its rich policy specification is very valuable for developing policy- driven autonomic systems, especially for service-oriented computing. We discuss our research on combining WS-Policy4MASC with the Adaptive Server Framework (ASF), which supports composing adaptive applications on Java and .Net platforms. WS-Policy4MASC enriches ASF with policy definition semantics and enables complex policy management for autonomic computing. The combination of WS-Policy4MASC and ASF forms a step towards business-driven IT management with autonomic features.

Abstract: CASCON 2000 The CASCON High School Programming Competition is a Java-based challenge that encourages high school students to discover the fun in computer science and information technology. Each CASCON 1999 team of two students will be instructed in the fantasy game environment of CodeRuler, a CASCON 1998 graphical, animated simulation game set in a medieval world of knights, castles, peasants and lords. Developed by Tim DeBoer for use at the ACM International Collegiate Programming contest, it is available on IBM alphaWorks (http://www.ibm.com/developerworks/java/library/j- Workshop reports coderuler/). Now in its third year, the CASCON High School Programming Competition has attracted many schools from across the Greater Toronto region. A Web site CASCON 2006 (http://www.developer.ibm.com/us/en/university/students/highschool/) managed by students working in the IBM Toronto Centre for Advanced Studies provides tools and information CASCON 2005 resources for high school students and teachers, and supports the annual Competition.

It will bring together leaders from across Canada in government, academia, education, and industry to CASCON 2002 examine data on the large gap between the current size of the computer science education pipeline and the size that would meet the current demands of industry and enhance Canadian CASCON 2001 international competitiveness in the future. Given the magnitude of the gap, a concerted and coordinated effort by all stakeholders is required. Ministers of education will join with teachers CASCON 2000 and principals, university faculty and administrators, and industry practitioners and recruiters in CASCON 1999 establishing short and long term objectives and plans for addressing the most important impediments to increasing the number of post-secondary graduates in computing and CASCON 1998 information sciences nationwide.
This is a full day workshop. The results of this workshop will be a set of specific action items, owners and resources for, and commitment to follow through with those action items. Plans for follow on meetings will also be established.
There will be a report prepared after the workshop that will be shared with all participants.
This workshop is being organized by the following people: Craig Boutilier, Chair, Department of Computer Science, University of Toronto Dave Scott, IBM Canada Elaine Leung, Manager of ICT unit of MEDT in Ontario with Erfon Mendoza and Carolina Botera Jacob Slonim, Dalhousie University Julia Kranjac, RIM Karen Klink, RIM Kelly Lyons, IBM Toronto Lab Kevin Schneider, Chair, Department of Computer Science, University of Saskatchewan Paul Swinwood, Information and Communication Technology Council (ICTC) Stephen Perelgut, IBM Toronto Lab Tamer Özsu, Director, David R.

Agenda: 10:00 to 10:45 Jacob Slonim will present data and results of the ICTC Report which includes: Numbers of CS students from universities across Canada Problems identified by people interviewed Suggested Solutions
10:45 to 11:00 Paul Swinwood will present the state of demand in Canada for IT 11:00 to 11:15: BREAK 11:15 to 12:00 We will then break into groups where each group will include representatives from industry, academia, high schools, fed. Gov't, prov. Gov'ts; Each group will identify ~5 recommendations or will pick the top ones from what was suggested in the opening presentation
12:00 to 1:00 LUNCH 1:00 to 2:00 Report back from first break out session: Go around the room group by group and iterate until all Recommendations are presented: One group will report a top Recommendation from their list Any other groups which have similar Recommendations, will report them at that time
The result will be 5-10 top Recommendations
2:00 to 3:15 The Groups (same groups) will then break out again and each group will take 1-2 of the top Recommendations and come up with concrete actions and owners for those actions 3:15 to 3:30 BREAK 3:30 to 4:30 Report back from the second break out session: Each group will present recommendations, actions, and proposed owners to the workshop participants for discussion and feedback.
There will be a panel of key stakeholders (decision makers from industry, high school, governments (fed and prov), academia) who will also provide feedback and who are ultimately responsible for providing resources / commitments to the recommended actions or revised actions. In this way, we guarantee that there will be follow-up and work carried out after the workshop.

CASCON 2002 Abstract: Buildling a Strategy to Increase Female Enrollment in Computer Science and Engineering in CASCON 2001 Canada CASCON 2000 Introduction: The participation of women in Computer Science and Engineering (CSE) disciplines has typically CASCON 1999 been low, but the last several years have witnessed an alarming downward trend throughout North America and Europe. In the past 5 years, shortages of students and workers in the IT CASCON 1998 sector have become a serious problem despite the diversity and flexible nature of many IT jobs. Over the next 15 years, Canada's job market will be seriously affected by demographic changes as well: currently half as many students are enrolled in Kindergarten as are enrolled in grade 12. Meanwhile, CSE disciplines and careers have become increasingly inter-disciplinary, and this change is not sufficiently reflected in our education system.
The knowledge of the interdisciplinary developments in CSE disciplines has barely reached enough K-12 or university students. The current trend of enrolment in interdisciplinary programs suggests a higher proportion of women in interdisciplinary studies than in conventional CSE. To reverse the downward trend of university enrolment, the pipeline needs to be built from K-12, through to university then to companies. Special attention must be paid to K-12 outreach with a focus on appropriately communicating the interdisciplinary aspects of CSE, as well as carefully identifying both our target groups and the resources required to advance in our outreach efforts. The direct goal of this workshop is to reach out to women; however achieving this goal requires us to also consider the impact that their educators, parents and friends have on them. Therefore, a strong outreach program targeting women must include efforts to change public perception. Although several IT companies, universities and governmental organizations have made substantial efforts in tackling this issue, a concerted effort to join forces is crucial for success.
A concerted effort: Among many approaches, we would like to highlight the outreach efforts of IBM and the University of Victoria. Both organizations have dedicated substantial funding for a professional position to organize and conduct outreach with a heavy emphasis on volunteers to act as mentors, group facilitators, and workshop instructors. This commitment from both organizations has lead to great progress in the area of attracting women to CSE, however the scope of the progress is limited by the fewness of such positions and the volume and demand for such outreach activities is not being met appropriately.
Building on this commitment, we would like to invite universities and IT companies in Canada to take a similar stance and to make it easier for their employees and students to participate in the delivery and development of outreach programs. The current system relying on volunteers for the delivery of the workshops is not sustainable. Many employees and students find it difficult to regularly commit to outreach efforts outside of their regular commitments: work, family, commute time, etc. Additionally, for the purpose of encouraging more women to consider CSE, much is asked of female employees and students in terms of outreach and mentoring. The outcome of this workshop is to identify goals for developing a plan to tackle this issue in a cohesive manner. A concerted effort between universities, companies and governmental agencies will surely create the synergy required to move forward.
Existing Programs – We don't have to start from scratch!
Below is a limited list of outreach initiatives and programs in CSE aiming at increasing the enrolment and retention of women in our undergraduate programs, from elementary school to 1st year university:
IBM's EX.I.T.E (EXploring Interests in Technology and Engineering) camps for middle-school girls, ages 11-13. These camps, one week-long events, are a world-wide initiative about engineering and science-related projects that is in its 8th year. IBM's I.G.N.I.T.E. camps targeted to K-12 first nation students Microsoft's Imagine Cup for students 16+, a multi-disciplinary international invention competition University of Victoria's initiatives for Women in Engineering and Computer Science in the Faculty of Engineering University of Victoria's SPARCS (Solving Problems with Algorithms, Robots, and ComputerS) in the Faculty of Engineering.
Both University of Victoria initiatives target not only students but also teachers, parents and counselors.
All of these programs, while having different target audiences, contain some overlap in the activities, strategies, and goals. An example are Lego Mindstorms workshops, where the children actively learn engineering, programming, and problem solving skills while designing and programming a Lego robot. Currently, the collaboration between existing programs is limited; a much larger synergy is required to prevent re-inventing the wheel and to facilitate the dissemination of best practices and leveraging of the various events and opportunities.
Workshop discussion: Can we find ways to deliver these in a more comprehensive way and can we leverage programs amongst each other?
Although these grassroots efforts are helpful, substantial changes in the education system and the public perception are needed to make a positive difference in reversing this alarming trend. To be successful in recruitment and retention of females, collaborative efforts between Universities and Companies is crucial. Only an industry-wide solution can curtail this industry- wide problem. Currently, the majority of outreach programs targeted at increasing both female and general enrolment of students rely heavily on volunteers, which creates sustainability concerns. To turn outreach efforts into professional and successful undertakings, more outreach positions have to be created in Industry and Higher Education. Existing initiatives should be delivered at a provincial or national level and receive sufficient funding. We propose to nominate a number of ambassadors at provincial and national levels to mobilize a network to deliver on these expanded initiatives. A concerted, strategic approach is the best path to transforming the current demographic into one where women reach a critical mass and all students reap the rewards of increasingly evolving interdisciplinary areas of study.
The objectives of this workshop are to build on existing initiatives, and take proposed solutions into the action phase. Members of the workshop will work in breakout groups to bring action plans to assigned issues.
Each portion of workshop will have an assigned owner who will commit to meeting with other sub-group owners to push progress of actions in the months after the workshop.
Sub-group discussion points:
1. Building a comprehensive National network of active and enthusiastic professionals by having connections across the country, schools, companies and government has the ability to deliver programs that otherwise would be only local, disparate events. Program owners in industry and academia would lead these networks to success.
2. Address the stigma associated with technology industry for girls and young women. Focus on communication plans that can be utilized cross-industry. Campaigns that incorporate positive and "cool" role models should be employed. How can this be done at an industry-wide level?
3. How do we influence the influencers? Who are the key influencers that affect decisions from grade school to post-secondary? How are we reaching parents, teachers, guidance counselors, peers?
4. Determine best practices then leverage and expand to increase coverage across the country.
5. How can we influence industry and academia to secure sufficient staffing and funding for these necessary outreach activities?

Format: SSME Research Workshop–3 Panel discussion SSME Research Workshop–4 Abstract: In the past few years, there has been a growing interest in the topic of Services Science, Management and Engineering (SSME), or simply, Services Science. Research activities within CASCON archives several traditional disciplines have been examining issues related to this general topic for quite some time, such as service-oriented architecture (SOA) in computer science, cross-channel and CASCON 2007 services marketing in business, social networking and communities of practice in social science, and process optimization in engineering. Although some of these activities span academic- CASCON 2006 school boundaries, the majority still remain within a single discipline. In order to establish a distinct SSME research tradition, we must grow the number and scope of interdisciplinary CASCON 2005 research activities that tightly integrate concerns, methodologies and results from all the above areas. To that end, the fundamental purpose of this workshop is to gather people from multiple CASCON 2004 disciplines in an effort to forge a more unified, interdisciplinary view of SSME research, and hence to progress towards establishing a research tradition in SSME. CASCON 2003
The workshop will begin with a panel of presenters who will give perspectives of SSME from CASCON 2002 different disciplines. The panelists will then address the following questions with input and participation from the workshop attendees: CASCON 2001 CASCON 2000 1. What traditional disciplines should feed into SSME research? Which "traditional" research results could inform the SSME research agenda? CASCON 1999 2.

Abstract
Service Science Aims to Understand Service Systems
Service science is the study of service: actions that one takes on behalf of another. But there really is no such thing as service science today – there is no single accepted, integrated, interdisciplinary scientific study of the service economy or service jobs. Service science is more like a movement whose goal is to focus attention on service-related problems, in which the basic unit of analysis is the service system, a configuration of people, technologies, and other resources that interact with other service systems to create mutual value. Just as computer scientists work with formal models of algorithms and computation, someday service scientists will work with formal models of service systems.
More precisely, service is the application of resources (including competences, skills, and knowledge) to make changes that have value for another. Service system complexity is a function of the number and variety of people, technologies, and organizations linked in the value creation networks. Knowledge workers depend on their knowledge, tools, and social- organizational networks to solve problems, be productive, continually develop, and generate and capture value. Service science must combine formal models with models of human behavior to understand service systems.

Abstract
The Unified Services Theory Perspective on Services
It is true that services science has been developing in separate disciplines. Nevertheless, principles and paradigms coming from one discipline can have value and application in other disciplines. This presentation will discuss a service perspective coming from business operations management known as the Unified Services Theory (UST). Although the UST comes from a business operations perspective, it has application and implications in other disciplines. For example, the phenomenon known as Web 2.0 is explained by the UST. Even Service Oriented Architecture can be modeled under the UST, with interesting insights.

Abstract
A New Service Paradigm: Seven Challenges to Combining Human and Automated Service Abstract A framework for managing human-automated hybrid service systems is considered that relates four levels of service management (strategy, design and implementation, delivery, and measurement) with three stages of the consumer's service encounter (pre-purchase, service encounter, and post-encounter). This framework intermeshes what the business does with what the consumer does, recognizing that the service-delivery process typically involves co- generating value with consumers. The approach also considers integration of multiple points of service delivery (employee, self, and automated), and the historical evolution of service delivery to include multiple pathways through these points of contact. This framework is used to highlight seven managerial challenges associated with delivering hybrid service.

Abstract
Some Issues on the Boundaries between Business and Service Oriented Systems Engineering
In the context of Business, a service activity is a process of value co-production between a customer and a business. On the other hand, in the context of Service-Oriented Computing, the term "service" denotes a network accessible software component that offers a coherent set of functionalities. As software systems are increasingly used to formalize, codify, drive and evolve the execution of business processes, it is interesting to examine the interplay between the two meanings of the term. In this presentation, we discuss some pragmatic observations regarding the potential role of SOAs in the economy, we identify some distinct types of applications envisioned to be developed in the SOA style, and we correlate some strategic business decisions with different types of SOA evolution scenarios.

CASCON 1999 Contact: rilling [at] cse.concordia.ca CASCON 1998 Abstract Many changes have occurred in software engineering research and practice since 1968, when Software Engineering as a domain was defined. With the ever increasing number of computers and their support for business processes, an estimated 250 billion lines of source code were being maintained in 2000, with that number rapidly increasing. The relative cost of maintaining and managing the evolution of a large software base represents now more than 90% of the total cost associated with a software product. The research community's focus was initially on developing new process models and tool support to provide monolithic applications written in third generation procedural languages. More recently, the focus has switched to developing and maintaining modern distributed systems deployed across a networked infrastructure using a variety of methods that must address the heterogeneous nature of today's Web-based systems.
Traceability, a key aspect of any engineering discipline, enables engineers to understand the relations and dependencies among various artifacts in a system. In a complex application domain like software maintenance, these knowledge resources need to be continually integrated from different sources (like source code repositories, documentation, test case results), different levels of scope (from single variables to complete system architectures), and across different relations (static, dynamic, etc.). It is a well-known fact that even in organizations and projects with mature software development processes, software artifacts created as part of these processes end up to be disconnected from each other. Consequently, one of the major challenges for maintainers while performing a maintenance task is the need to comprehend this multitude of often disconnected artifacts created originally as part of the software development process. From a maintainer's perspective, it therefore becomes essential to establish and maintain the semantic connections among these artifacts. This lack of traceability among software artifacts is caused by several factors, including: (1) the fact that these artifacts are written in different languages (natural language vs. programming language); (2) they describe a software system at various abstraction levels (requirements vs. implementation); (3) processes applied within an organization do not enforce maintenance of existing traceability links; and (4) a lack of adequate tool support to create and maintain traceability.
The missing traceability among software artifacts becomes a major challenge for many software maintenance activities. As a result, during the comprehension of existing software systems, software engineers have to spend a large amount of effort on synthesizing and integrating information from various sources to establish links among these artifacts. Existing research in software traceability focuses on reducing the cost associated with this manual effort by developing automatic assistance in establishing and maintaining traceability links among software artifacts.
Topics to be include, but not limited to: source code traceability requirements traceability link recovery and automated methods, Information Retrieval (IR) and Natural Language Processing (NLP) for traceability analysis evolution of traceability links link semantics, ontologies and other knowledge representation formalisms for traceability visualization of traceability links, certification, processes and policies, tracing across heterogeneous environments, Session Plan This half-day working session will be logically structured into three parts: past, present, and future. Each part will be centered on a panel session of presentations and discussions representing different stages of development in the field. Research topics will be drawn from established and new research approaches. The objective is to have representative cross sections of the community; given time and space constraints for the workshop, it is impossible for it to be complete or exhaustive. Participants are encourage to submit by e-mail, specific interests they would like to see discussed in the forum (E-mail: rilling[at]cse.concordia.ca).
The Past The first part of the workshop will provide introspection on key developments early in the history of traceability over the last 30 years. It is also desirable that newcomers to the field will be able to better appreciate early work and relate it to their current research or the challenges they are experiencing in their own organizations.
The Present The second part of the session will examine relatively recent developments in the field, covering the years 2000 – 2007, highlighting these current trends and providing a state of the art review of the currently ongoing trends in software traceability.
The Future The third part of the session will attempt to provide a roadmap for current and ongoing challenges to be addressed by the research community and organizations. This part of the workshop will be a mix of a panel session and a truly interactive "working" session. For the interactive session, participants will be divided into smaller working groups to discuss, identify and present traceability challenges relevant to their particular research/organizational context. Possible topics for discussion include: - Competitive evaluation of automatic traceability recovery: tasks and metrics - Challenges in software traceability - Integration of traceability in software processes Participants are encouraged to submit their own topics for discussion; either during the workshop itself, or by email (see above).

Abstract
While developing software systems, it is rare that the initial implementation of a system will correspond to the final version at its retirement. Changing customer needs lead to ongoing adaptive requirement changes and new versions of the same system. In fact, software implements solutions that are expected to change periodically, to allow systems to adapt to environment changes. The efficient management and execution of these changes are critical to software quality and managed evolution of such systems. The presentation will highlight some of these challenges the Canadian Forces are currently facing.
Juergen Rilling Concordia University Juergen Rilling is an Associate professor at Concordia University in Montreal, Canada, His research focus is in the areas of software evolution, source code analysis and software traceability. He leads the software maintenance and program comprehension research group at Concordia and is a program committee member of several international workshops and conferences related to his research area. His current main research interest focuses on modeling and supporting different aspects of software traceability. He also has several years of industry experience as a software engineer. Dr. Rilling holds a Ph.D. from the Illinois Institute of Technology in Chicago, a M.Sc. in Computer Science from the University of East Anglia, UK, a Diploma in Business Information Management (Dipl.-Inform. (FH)) from the school of Informatics, Hochschule Reutlingen, Germany.
Abstract
Software maintenance involves the integration, abstraction and analysis of different knowledge resources and artifacts. Maintainers are typically left with no guidance on how to utilize these resources to complete specific maintenance tasks. The presentation will address a variety of issues related to establishing traceability links between software artifacts, maintenance processes and available knowledge resources and current and future trends to address these challenges will be discussed.
René Witte University of Karlsruhe, Germany René Witte is currently a research associate at the Institute for Program Structures and Data Organization (IPD), University of Karlsruhe, Germany, where he heads the Text Mining group. His work encompasses foundations in computational linguistics, technical aspects of natural language processing systems including ontologies and semantic desktops, as well as the application of text mining in diverse areas such as news analysis, building architecture, biomedical research and discovery, and software engineering. He also has several years of industry experience as an information systems consultant. Dr. Witte holds a Doctorate of Engineering (Dr.-Ing.) and a Diploma in computer science (Dipl.-Inform.) from the Faculty of Informatics, University of Karlsruhe, Germany.
Abstract
Documents written in natural languages constitute a major part of the artifacts produced during the software engineering lifecycle. Especially during software maintenance or reverse engineering, semantic information conveyed in these documents can provide important knowledge for the software engineer.
In this talk, we discuss applications of natural language processing (NLP) to documents within the software engineering domain. A particular focus will be placed on automatically establishing traceability links between source code and its corresponding documentation. We present results from an approach based on the automatic population of an ontology, which allows to cross-link software artifacts represented in code and natural language on a semantic level.

The ability to adapt software offerings quickly to client organization over the last mile is critical to customer satisfaction, productivity, time-to-value, and ROI, especially in CASCON 2002 today's fast-moving business environment. If a client cannot get the value within a reasonable period of time, or a potential customer perceives a large amount of adaptation efforts before CASCON 2001 the software can be used, the software provider risks loss of customers and the software becomes of little value for both the consumers and the provider. CASCON 2000

Abstract
Title: Compiler-Driven Dependence Profiling to Guide Speculative Parallelization/Optimization.The need for high performance per watt has lead to the development of multi-core systems such as the IBM's Cell processor and POWER5 dual-core processor. Efficient exploiting of the performance potential of these systems necessitates program parallelization. Recently, thread-level speculation (TLS) has been proposed as a means to parallelize difficult-to-analyze serial codes. One of the key aspects of TLS is task selection for speculative execution. To this end, we propose an approach for automated profiling of program dependences. The benefits of our approach are twofold:
(a) The profiling information can be used to assess, in part, the profitability of applying TLS on the candidate program region. Likelihood analysis can be used for pruning the set of candidates for speculative parallelization.
(b) The proposed approach serves as a means for clustering dependences - static vs. dynamic - in a given program region. This in turn can provide a valuable feedback to the compiler to guide program optimization/parallelization. In addition, the dependence information may be fed back to the programmer.
Our preliminary results show that our dependence profiling approach is very effective in identifying profitable candidates for TLS.

Abstract
Title:Application Mapping and Optimization for NoC Based CMPs. Chip multiprocessors (CMPs) are expected to be building blocks for future computer systems. While architecting CMPs is a challenging problem on its own, programming them is even more challenging. As the number of cores accommodated in chip multiprocessors increases, network-on-chip (NoC) type communication fabrics are expected to replace traditional point-to- point buses. Focusing on array and loop intensive applications, this talk (1) explains a compiler directed application mapping strategy to NoC based CMPs, and (2) discusses several optimizations that reduce power consumption of the mapped application without affecting performance much. We defend an approach where the NoC architecture is "exposed" to the compiler which in turn schedules both computations and communications to maximize performance and reduce power consumption.

Abstract
Title: Software Behavior Oriented Parallelization. Many sequential applications are difficult to parallelize because of unpredictable control flow, indirect data access, and input-dependent parallelism. These difficulties led us to build a software system for behavior oriented parallelization (BOP), which allows a program to be parallelized based on partial information about program behavior, for example, a user reading just part of the source code, or a profiling tool examining merely one or few executions.
The basis of BOP is programmable software speculation, where a user or an analysis tool marks possibly parallel regions in the code, and the run-time system executes these regions speculatively. It is imperative to protect the entire address space during speculation. The main goal of the paper is to demonstrate that the general protection can be made cost effective by three novel techniques: programmable speculation, critical-path minimization, and value-based correctness checking. On a recently acquired multi-core, multi-processor PC, the BOP system reduced the end-to-end execution time by integer factors for a Lisp interpreter, a data compressor, a language parser, and a scientific library, with no change to the underlying hardware or operating system

Abstract
Title: Easing Program Transformations with the Nanos Mercurium Compiler. This talk will present the structure of the Nanos Mercurium compiler, a research compiler for C and C++, developed at the Barcelona Supercomputing Center oriented to implement program transformations. The compiler is organized as a basic core, and a set of passes that can use the services offered by the core to implement different program transformations. The core deals with the parsing of the input file, and produces an abstract syntax tree (AST). Then, it disambiguates the AST using semantic information. Each new phase of the compiler is implemented as a dynamically loaded shared library. Each phase is given the intermediate representation (AST and semantic information) resulting from the previous phase. At the end of the execution, the resulting AST is then printed onto the output file, which can be compiled by a native compiler on the target machine.
Since dealing with the AST directly is usually complex, we have implemented the option for the programmer to simply provide a valid C/C++ string representing the code transformation. The compiler parses the string and it generated the new AST to replace the old code. During the presentation, we will show how this technique is used to implement the OpenMP 3.0 transformations, including the new task directives. The compiler is publicy available at http://www.bsc.es.

Abstract
Title:The concurrency revolution in C++0x standard. C++ as it is today does not support threads. Neither does C. C++0x is the next revision of the C++ Standard. A number of new features are proposed including Concepts, Garbage Collection and Concurrency. This talk will describe the addition of C++0x features that facilitate concurrency. This includes a memory model, atomic operations, thread-local storage, threads API, support for C+ constructors and destructors, to thread pools and futures. OpenMP is a shared memory parallel specification and they are also adding task-based parallelism to support irregular tasks in the next revision. In the hardware, multicore chips are now available on laptops. The concurrency revolution is here and this will help you understand it. If there is time, garbage collection will also be covered.

Abstract
Title: Challenges in Parallelizing Irregular Computations. In this talk, we will discuss challenges in parallelizing scientific and data analysis applications that primarily involve irregular or unstructured algorithms, Such algorithms hold the potential for near linear-time solution but suffer from poor data locality and reuse. However, they inherently have a large degree of task and data parallelism that may be exploited for application speedups. We will discuss the nature of parallelism in such applications and some strategies for enabling efficient implementations on chip multiprocessors.

Abstract
Title: Challenges of Compiling and Optimizing for Unified Parallel C. Unified Parallel C (UPC) is an emerging parallel language based on the Partition Global Address Space (PGAS) memory model. This relatively simple language extension to ISO C allows development of high performance applications on clusters of parallel machines, and is designed with ease of use as one of its fundamental goals. UPC incorporates simple language constructs enabling the distribution of shared data across all threads of execution, while assigning to each thread a logical association (or affinity) to a portion of the global address space. Thus UPC permits each thread to access a portion of the shared data locally without incurring the cost of remote accesses. In this presentation we will give an overview of the most interesting UPC language features. We will describe an implementation of the UPC language specification, and some of the compiler optimizations that are necessary to achieve good performance under the distributed shared memory programming paradigm.

CASCON 2005 Abstract: An Adaptive System is one that adapts its behaviour to the environment, is agile so that its CASCON 2004 behaviour can be easily and rapidly changed by the developers and users to reflect new requirements, and is autonomic, exhibiting self-managing properties. CASCON 2003
This workshop will focus on two key complementary areas of research that enable adaptive CASCON 2002 systems: (a) Model-driven engineering (MDE) technologies and methods; (b) Platform virtualization technologies. Both of these serve to hide the highly inflexible and technology- CASCON 2001 specific nature of the underlying computing technology, thereby greatly simplifying the tasks of software design and evolution as well as its provisioning and operation. Adaptive systems will CASCON 2000 allow companies to save cost by optimizing the computing resources usage as well as by automating the management tasks currently performed by experts; to better adapt to changes CASCON 1999 in operating conditions by changing the application behaviour; and to faster deploy new applications and updates by shortening the development life cycle.

Abstract
Virtualization technology opens up a range of new possibilities for the management of shared data centers, offering a new degree of granularity to the dynamic resource management decisions. Server virtualization can be exploited to efficiently manage heterogeneous workloads, at the cost of adding some complexity to the placement algorithm. We explore a utility-based placement algorithm for heterogeneous workloads that introduces fairness goals, that is, tries to equalize the satisfaction of all applications at each placement change. We'll look into the characteristics and performance of the technique through a complete evaluation of the algorithm.

Abstract
"CancerGrid: Model- and Metadata-Driven Clinical Trials Informatics"
The CancerGrid project (www.cancergrid.org www.cancergrid.org>) is developing a software architecture for tissue-plus-data clinical trials. The project is using a model-and metadata-driven approach that makes the semantics of clinical trials explicit; the trial protocol, required anyway for regulatory purposes, is a sufficient model from which to generate software support, and suitable metadata annotations facilitate dataset discovery and reuse. The architecture is based on open standards for the composition of appropriate services, such as: randomization, minimization, clinician identity, serious adverse
events relay, remote data capture, drug allocation and warehousing, and form validation. We believe that the approach has wide applicability, to any data-rich distributed community.

CASCON 2002
CASCON 2001 Service-oriented architecture (SOA) is a recent evolution in distributed middleware. Many of today's software engineering course projects require student to integrate disparate components CASCON 2000 across a heterogeneous networked infrastructure using technologies such as SOA. While SOA CASCON 1999 does hold the promise of successfully accomplishing this task, mastering the design, development, and deployment of SOA-based systems places a considerable pedagogical burden CASCON 1998 on the faculty and students.
Team-based projects are the cornerstone of many software engineering courses. In these projects, the students learn the importance of topics such as project management and issues of scale that separate software engineering from program development. The focus of such projects is not on learning about a particular technology such as SOA, but on using it as a means to an end. However, this cannot be achieved without a sufficient understanding of the underlying technologies. This means the instructor must carefully balance the time and effort needed to learn about SOA, and the time and effort needed to learn about all other aspects of software engineering required to make the course project a success. This may be particularly difficult to achieve considering the relative complexity of SOA: it requires knowledge that is both broad and deep to be leveraged effectively.
From an industry perspective, many employers often lament that they must provide extensive (re)training to new employees. One of the reasons given for this situation is that the students haven't learned in school what the company considers to be important. To be sure, there will always be issues specific to the corporation that the new employee must acquire. But for software engineering, it seems odd that the projects students are given during their final years as an undergraduate are usually not indicative of the type of projects they will likely be working on in an industrial setting. This is particularly acute for SOA, since many companies and consultancies are heavily invested in converting legacy systems into valuable corporate assets in the guise of business services.
This symposium will explore how educators and industry can work together to develop a more rewarding educational experience for all stakeholders involved.
Why hold this symposium at CASCON 2007?
CASCON enjoys an enviable reputation as an event that brings together the top academics in Canada (and abroad), along with representatives of leading information technology companies and government agencies. The CASCON workshops in the past have proven to be very valuable to all involved. The organizers of this proposed symposium have participated in numerous CASCON events, going back to 1991. Indeed, SWECP 2007 will be a sequel to workshops that were successfully held as part of the CASCON 2002, 2005, and 2006 conferences.
There are other conferences and workshops related to software engineering education. For example, the IEEE's CSEE&T and the ACM's SIGCSE to name just two. However, none of these events focuses exclusively on the undergraduate course projects. While this is a narrow topic, it is a very important one. We believe that it deserves its own forum for discussion. Furthermore, we are not aware of any venue that is currently discussing SOA from an educational and pedagogical perspective. Since SOA is such an important new development, it's important that faculty and students learn how to properly engineer SOA-based systems.
Having this fourth international symposium at CASCON makes good economical sense, both for the participants (who can lower their travel costs) and for the organizers (who can leverage the infrastructure provided by the IBM Centre for Advanced Studies). The conference location of Metropolitan Toronto will make it easier to attract local participants. The established pedigree of CASCON ensures that the workshop will have the support it needs to succeed.
How will the symposium be structured?
This will be a half-day event, held in a single room to accommodate the expected 25 participants. The symposium will be structured around a handful of invited presentations from recognized experts in the field, and a panel session involving a selected set of opinion makers from academia, government, and industry. For the panel session, following each brief position statement, the panelists will engage in structured discussion with the rest of the symposium participants. The idea is to foster the exchange of ideas and information in an informal setting, but with some boundaries placed on topics and time to ensure that the symposium is on schedule.
The symposium will provide an opportunity for the exchange of information related to areas including (but not limited to): Course modules for learning SOA principles Lab exercises for experimenting with SOA technologies The use of commercial tools in the course project Constructing and managing teams, particularly matching business needs and IT capability Differences between undergraduate course projects and M.SE. SOA-based projects
A summary document containing the workshop findings will be distributed electronically to registered participants some time after CASCON. For example, for the 2005 and 2006 SWECP workshops, a summary report was published as part of the IEEE CSEE&T 2006 and 2007 conference proceedings, respectively.
Who will participate in the symposium?
The people who are likely to participate in the symposium are primarily from academia: lecturers, faculty, and students. The people most interested in this topic will be educators responsible for teaching software engineering classes in a university setting, particularly those who are willing to try new technologies such as SOA in a classroom setting. Students who are intrigued by SOA may also find the discussion of education resources and learning techniques to be of value.
Participation from industrial representatives, particularly those in IT-oriented business consulting (e.g., IBM Global Services), would greatly improve the symposium's tenor. Many companies offer their own specialized training sessions, sometimes using mock projects that are similar to the projects university students' experience. They also are early adopters of SOA as a means of leveraging existing legacy assets. It is only through dialog between academia and industry that the improvements can be made to this aspect of the undergraduate curriculum.
There is no requirement for any participant to be actively teaching a software engineering course; we will certainly not exclude anyone from sitting in on part of the symposium. The main requirement is an interest in improving the current situation.
Who is organizing the symposium?
The workshop will be organized by three faculty members: Scott Tilley from the Florida Institute of Technology, Ken Wong from the University of Alberta, and Spencer Smith from McMaster University. All three have extensive experience serving on program committees and chairing international conferences and workshops. The fact that the organizers come from different countries will lend valuable diversity to the workshop discussions. Coupled with participation from workshop attendees from industry and government, this should help ensure that the results from the workshop are widely applicable.

Abstract
Service-Oriented Architecture (SOA) is rapidly becoming the dominant architectural paradigm in many enterprises. The SOA approach emphasizes loose coupling between the different systems in the enterprise. Applications communicate with each other only via well designed service interfaces and remain unaware of each other's implementation. Structure of service interfaces is of primary importance in SOA projects. Poorly designed service interfaces can have a profound negative effect on all applications that need to use these interfaces. Well-designed service interfaces will accelerate project schedules and make your SOA solution more responsive to business needs. In this session I will discuss the best practices for service interface design. Session attendees will learn how to design their services so that their SOA solutions don't re- create problems inherited from previous implementations.
Serjik G. Dikaleh IBM Serjik is an IT Architect working with IBM Integrated Software and Services for WebSphere. He has implemented many SOA solutions for IBM customers. He specializes on implementations involving the WebSphere ESB and the WebSphere Process Server products. Abstract
The presentation will cover the following topics: - Using XML namespaces - Refactoring existing code - Implementing a service registry - Documenting the solution - Source control with ClearCase UCM and WebSphere Integration Developer (WID) - Unit and Integration Testing within and outside WID - ESB Performance Testing

Software architecture can be a critical factor in global (ie, geographically and temporally separated) software development. Understanding what software architects do in practice is Related links necessary to the enterprise of providing techniques, methods, process, tools and IBM University Relations technologies to support the development and use of soft-ware architectures in a global Programming Contest context. We present the results of a multiple case study of how architects view and address Central the issues in transforming requirements into architectures in practice. We then summarize the important lessons learned from these practicing architects about this critically important IBM alphaWorks step in creating and evolving software systems.

In recent years, UML activities have become widely accepted for specifying the dynamic behaviour of use cases. For an adequate specification of use cases in the context of interactive systems, however, activities must be adapted in several aspects. We present a tailoring of activities to these needs yielding so-called interaction-oriented activities. From such activities we derive two kinds of activities focusing on the development process. The first activity is a user-friendly variant that is devoted to the requirements engineering stage. The second activity is obtained by a smooth transformation of the first one. It is a more detailed variant serving as a specification guiding the implementation. We demonstrate how such an activity can systematically be mapped to a specific target platform. As an example platform we choose J2EE with Web tier based on the Web framework Struts.

Inspecting Designs in the Context of Model-Driven Development Authors: Terry Shepard, Diane Kelly, Ron Smith, Ron Chisholm, Todd Jackson, and Paul Mondoux, Royal Military College of Canada
Model Driven Development (MDD) is becoming increasingly popular. One of its potential strengths is the ability to inspect the model sooner and with greater precision than has been possible with conventional forms of expression of design. A study was conducted to explore the issues of model inspection when the design is expressed in a particular MDD tool, RoseRT. Four inspectors with varying levels of experience with RoseRT inspected a total of three models, all derived from the same set of requirements. The results suggest that there will be significant variations in personal inspection processes for MDD and that the tool supporting the model needs to support inspection. The techniques used by each inspector are presented, together with an analysis of findings and observations for future inspections.

A Lightweight Approach to State Based Security Testing Authors: Songtao Zhang, Thomas Dean, and Scott Knight, Queen's University
State based protocols are protocols in which the handling of one message depends on the contents of previous messages. Testing such protocols, for security or for other purposes, usually means specifying the state space of the protocol using either a state machine abstraction or a implementing the state information in code. This paper presents a novel approach where captured data sequences are mutated and replayed to test the security. A protocol description containing data dependencies is mapped to the captured sequence and used to handle state dependent fields when replaying the sequence to inject the mutants.

Improving Textual Deception Detection in Email Authors: Smita Gupta and David B. Skillicorn, Queens University
Pennebaker developed an empirical model for detecting deception in text. When this model was applied to the Enron email dataset, it detected both true deception, but also emails with varying degrees of spin. We address the problem of refining the deception model to differentiate these different shades of deceptiveness. Organizations must often examine internal and external email to deal with issues such as intimidation, sexual harassment, and fraud; either in real-time or forensically, when an incident has occurred. An improved deception model makes it easier to select a relevant set of emails for examination.

Hybrid vs. Monolithic OS Kernels: A Benchmark Comparison Authors: Dylan Griffiths and Dwight Makaroff, University of Saskatchewan
Operating Systems are huge, complex pieces of software that are difficult to design and maintain. Given the scale of the software and the inclusion of third-party drivers, they are also hard to keep secure and reliable. Microkernel-based operating system designs offer improvements to implementation complexity and modularity of code in a system, but have been perceived to have serious performance drawbacks. Microkernel research has continued, despite the fact that the perception of poor performance has hampered their widespread adoption. The increase in the speed of both processing and memory access has led some to reconsider the relative advantages and disadvantages in microkernel design. In this paper, we investigate the performance of modern and popular operating systems designed for use on personal workstations using a standard process-based benchmark. The experiments were executed on commodity hardware and the results indicate that the characteristics of the hardware dominate the differences in the architecture of the operating system kernels, lending support to the idea that microkernels may be poised to gain widespread deployment.

CasSim: a Top-level-simulator for Grid Scheduling and Applications Authors: Edward Xia and Igor Jurisica, University of Toronto; Julie Waterhouse, IBM Canada Ltd.
Grid computing has rapidly become a promising computing paradigm. Effective and efficient use of grid resources is achieved by using scheduling heuristics. Many such heuristics have been developed over the last decade. However, the dynamic and heterogeneous nature of the grid leads to two challenges. First, how can we rank and compare the efficiency and performance of those heuristics in general? Second, as none of the heuristics performs well in all conditions, how can we determine and choose the best one under certain conditions? The first challenge is traditionally solved by using simulators, emulators, experimental testbeds, etc. In this paper, we focus on the solution for the second challenge, and describe CasSim (Centre for Advanced Studies Simulator).Our main idea is to use a simulator to dynamically select the best heuristic. In contrast to other grid simulators, CasSim has a simple abstract model, and can easily and quickly compare different scheduling heuristics. We apply a simple cost matrix model for CasSim. In order to get costs, i.e, run times, from the real system dynamically, we create a case base to store historical data, and use a case- based reasoning approach to estimate them. Experimental validation of CasSim shows that the difference in the total run time of executing a set of jobs under the real grid and the simulation of CasSim is about 10%, and the approach of dynamically selecting the best heuristic can improve performance by 3% ~ 30%, compared to using a pre-selected heuristic. Since CasSim selects heuristics accurately, it can be used in the real system. In addition, we extend CasSim to support a wider range of applications by enabling users to define costs.

Component-oriented Version Management for Hardware Software Co-design Authors: Tien N. Nguyen and Zhao Zhang, Iowa State University
Nowadays, the development of modern computing devices involves a substantial and growing part of software development. A great challenge for engineers is to manage the evolution of a system with several components in the face of mounting complexity due to concurrent hardware and software development. The key limitations of existing version control tools used for a hardware software co-design process include their inadequacy in representing semantics of design models and inability to manage versions of both hardware designs and associated software components in a cohesive manner. Thus, it is difficult to track the logical interdependencies between the changes to hardware and software components in an embedded computing system over time. This paper presents a novel component-based version management mechanism that is capable of capturing and versioning the underlying logical contents of components in system design models and their associated software artifacts in a cohesive manner. This paper also illustrates our approach in creating a prototype of a versioning system for a hardware software co-design process.

Online Shopping for Technology Products: Designing Web Portals to Address Buyer Behaviours, Attitudes and Individual Differences Authors: Matthew Bedernjak and Mark Chignell, University of Toronto
Technology products are among the fastest growing leaders in online sales categories. This provides an exciting opportunity for portal designers and researchers to understand underlying constructs and relationships in online technology product purchasing, and as a result design portals to maximize usage and ultimately revenue. This paper looks at three experimentally established underlying constructs related to online technology product purchasing: 'Search and Compare' behaviour, an attitude of 'Comfort and Trust of the Internet', and a 'Concern for Portal Reliability/Function'. It discusses design implications related to the three constructs, with a focus on the differences between non-technology and technology product buyers, personality factors, individual differences (such as gender or age), and other buying predictors (for example electronic social networking and order tracking). Three previously experimentally established clusters (stereotypes) of online technology buyers are described - the 'weary searcher', the 'confident browser', and the 'sophisticated searcher'. Design implications related to each of these clusters is given. A tool developed by the investigator, the Online Technology Purchasing Inventory (OTPI) is also presented, and its use in measuring underlying constructs and predictive relationships is described.

Towards Autonomic Workflow Management Systems Authors: Markus Strohmaier and Eric Yu, University of Toronto
Autonomic Computing represents a vision of systems that exhibit self-configuration, self- optimization, self-protection and self-healing behaviour. One goal of this initiative is to prepare systems for dealing with increasing dynamics and complexity in their environments. At the same time, current research in the domain of workflow management explores new ways of dealing with change in workflow management systems on different levels. Based on the observation of partly converging research efforts, we investigate synergy potentials between autonomic computing and adaptive workflows from a perspective of change and finally introduce a five-level conceptualization of autonomic work-flow management systems that exhibit different degrees of autonomous behaviour.

Exploring a New Space of Features for Document Classification: Figure Clustering Authors: Nawei Chen, Hagit Shatkay, and Dorothea Blostein, Queen's University
Automatic document classification is an important step in organizing and mining documents. Information in documents is often conveyed using both text and images, which complement each other. Typically, only the text content forms the basis for features that are used in document classification. In this paper, we explore the use of information from figure images to assist in this task. We explore image clustering as a basis for constructing visual words for representing documents. Once such visual words are formed, the standard bag-of-words representation along with commonly used classifiers, such as the naïve Bayes, can be used to classify a document. We report here results from classifying biomedical documents that were previously used in the TREC Genomics track based on the image-based representation. Efforts are ongoing to improve image-based classification and analyze the relationships between text and images.

Wednesday, October 18, 2006, 9:00 a.m. Topic: Collaborative Innovation: A New Lever in Information Technology Development
Dr. Bernard Meyerson, IBM Fellow, VP Strategic Alliances and Chief Technologist; IBM Systems & Technology Group
Presentation material available here
Dr. Meyerson is Vice President for Strategic Alliances and Chief Technologist of IBM's Systems and Technology Group. Dr. Meyerson joined IBM Research as a Staff member in 1980, leading the development of silicon: germanium and other high performance technologies over a period of ten years. He then led a series of development organizations within IBM focused on communications and semiconductor technology, creating from that work a number of major business endeavors encompassing applications spanning the range from pervasive wireless enablement (802.11x) to high end data transport.
Dr. Meyerson was appointed Chief Technologist of IBM's Technology Group in 2001, in 2003 assuming operational responsibility for IBM's Semiconductor Technology Research and Development as head of the SRDC (Semiconductor Research and Development Center). In that role he led the world's largest semiconductor development consortium, members being Sony, Toshiba, AMD, Samsung, Chartered Semiconductor, and Infineon. In December 2005, he was appointed as Vice President for Strategic Alliances and CTO of IBM's System Technology Group.
In 1992, Dr. Meyerson was appointed an IBM Fellow, IBM's highest technical honor. He is also a Fellow of the American Physical Society and the IEEE. Throughout the years Dr. Meyerson has received numerous awards for his work including: the Materials Research Society Medal, the Electrochemical Society Electronics Division Award, the IEEE Ernst Weber Award for the body of work culminating in the commercialization of Si-Ge-based communications technology, and the IEEE Electron Devices Society J. J. Ebers Award. He was cited as "Inventor of the Year" in 1998 by the NY State Legislature, and was recognized in 1999 as "United States Distinguished Inventor of the Year" by the US IP Law Association and the Patent and Trademark office. In 2002, he was elected to the National Academy of Engineering.
Dr. Meyerson and his team have also been the subject of a long-running study on the topic of innovation in large organizations, culminating in the 2001 Harvard Business School Press publication titled "Radical Innovation; How Mature Companies Can Outsmart Upstarts".
Abstract:
The IT industry has reached a crossroads, where semiconductor development costs are soaring, while at the same time, progress in raw silicon device performance has begun to lag. The phenomena behind both the aforementioned events is that classical scaling, the year on year systematic shrink of device dimensions, has reached the physical limits of several key technology elements. As a consequence of this, it is now vital that companies intent on remaining leaders in the IT field focus on the simultaneous optimization of a very broad range of system attributes, ranging from new materials for transistors to sophisticated hypervisor technology a methodology known as Holistic design. This forces unprecedented collaboration horizontally across organizations in this space, and between companies seeking to mitigate the extraordinary costs of such efforts. The new behaviors forced by these changes fall under the umbrella of collaborative innovation, and this talk will elaborate on specific examples of this new strategic direction.

Abstract:
World wide, the annual sales in computer games exceed $20 Billion. Upcoming game titles are hyped for months in advance of their release and the debut of a major game can garner massive media attention. This public attention comes with increased consumer expectations. Game development cycles of three to four years are quite common and many games have budgets in excess of $25 million (US). For example, the recently released (2006) Oblivion role- playing game required almost 4 years of development. Unlike movies, the cost of a game release is dominated by the salaries of the technical and creative staff and most of the cost is in content creation: writers to design the game story, artists to create the visual effects, and computer scientists to build the technology and tools needed to realize the game. In many ways, it is more difficult and labor-intensive to build a blockbuster game than a blockbuster movie.
The game story is a multi-faceted major component of content. It includes the plot, sub-plots, characters, and their interactions with the player character. The situation is complicated by the interactive nature of games. Unlike movies with their linear story lines, in computer games the player can influence what happens in the story. Non-linear story lines complicate the content creation process, since the author must anticipate all possible player actions and handle them in a meaningful manner. In fact, the sophistication of the game stories and the growing need for non-linearity in the story lines are increasing not only the cost of game content development, but also other components of the game life-cycle such as quality assurance, playability testing, maintenance, customer support and sequel production.
Creating game-story-related content and translating this into the program code necessary to create the desired behavior at game-play time has always been a bottleneck in the game- development process. For example, when an author creates some content, it must be specified precisely to the programmer who then writes code to implement this content in the game. This process is fraught with errors: the author might make errors in the specifications given to the programmers and/or the programmers might make errors in implementing the author's specifications. Ideally, the programmer should be eliminated to avoid these errors. One of the dreams of game development is for the creative authors to specify the game content without having to rely on programmers to implement their vision.
This talk will describe a new approach, based on generative patterns, that empowers game designers to automatically generate scripting code to control their content as they create the content. The talk will illustrate this approach using ScriptEase, a tool developed at the University of Alberta and Neverwinter Nights, a very popular computer role-playing game developed by Bioware Corp. The talk will include demonstrations of the approach and results from case studies that show its success.

Abstract:
As North America grapples with threats to its global dominance in technology leadership and the world struggles with a host of environmental, political and social issues, it has become clear that conducting "business-as-usual" is no longer a viable model.
No longer can we afford to accept a landscape in North America where women represent only 18% of our scientists and engineers. Studies suggest that when women are part of a diverse leadership team, global competitiveness, creative innovation and even financial performance are improved. But women are in charge of only a few of the top publicly traded companies and hold only a few board seats among public corporations. They fare even worse with board positions among tech companies. If we invest in the development of technical women leaders we will not only shatter the glass ceiling we may shatter profitability records, as well.
President and CEO of the Anita Borg Institute for Women and Technology, Dr. Telle Whitney, will highlight the state to the technology industry and discuss the importance of engaging those most heavily under-represented (women) in vital engineering and technical professions. She will provide specific examples of skills and tools for technical leadership. Drawing her wealth of experiences and programs at the Anita Borg Institute she will highlight why involving more of those creative minds in the creation, use and leadership of technology is smart for our business, good for our nation and will encourage a generation of women to stretch the limits of their imagination.

CASCON Tuesday, Oct 17 paper presentations CASCON archives CASCON 2008 CASCON 2007 CASCON archives Session: Program Comprehension ACM-ICPC CASCON 2006 Towards Understanding Program Comprehension Yann-Gaël Guéhéneuc, Université de Montréal CASCON 2005
Program comprehension is a very important activity during the development and the CASCON 2004 Related links maintenance of programs. This has been actively studied in the past decades to present IBM University Relations software developers with the most accurate and, hopefully, most useful information on the CASCON 2003 Programming Contest program organisation, algorithms, executions, evolution, and documentation. Yet, only few Central works exist to understand concretely how software developers obtain and use this information. CASCON 2002 IBM alphaWorks Software developers mainly use sight to obtain information about a program, usually from CASCON 2001 IBM developerWorks source code or class diagrams. Therefore, we use eye-tracking to analyse the acquisition and use of this information by software developers. We collect data about the use of class diagrams DB2 for Academics by software developers during program comprehension using eye-tracking, and introduce a new CASCON 2000 WebSphere for Academics visualisation technique to aggregate and to present the collected data. We also report the results and surprising insights gained from two case studies. CASCON 1999 back to list CASCON 1998
Towards Evidence-Supported, Question-Directed Collaborative Program Comprehension Benjamin Chu and Kenny Wong, University of Alberta
Many software maintenance and enhancement tasks require substantial developer knowledge and experience in order to be efficiently completed on today's large and complex systems. Preserving explicit forms of documentation that are accessible by large development teams with regular developer turnover is a difficult problem. This problem can result in temporal and spatial miscommunication, an easily lost cognitive work context, and ultimately unmaintainable software. The research described in this paper hypothesizes that these problems may be addressed by a collaborative and semi-structured goal-question-evidence methodology for program comprehension that has three primary aspects. A prototype tool has been developed which shows promise for the methodology. back to list Combined Static and Dynamic Analysis for Inferring Program Dependencies Using a Pattern Language Inbal Ronen, IBM Haifa Research Lab; Nurit Dor, Panaya Inc; Sara Porat and Yael Dubinsky, IBM Haifa Research Lab One of the challenges when examining enterprise applications is the ability to understand the dependencies of these applications on external and internal resources such as database access or transaction activation. Inferring dependencies can be achieved using a static approach, a dynamic one or a combination of the two. Static analysis tools detect dependencies based on code investigation while dynamic tools detect dependencies based on runtime execution. The combination of these two approaches is essential for a complete and precise analysis. In this paper we present and illustrate a technique for inferring application dependencies on resources. The technique is based on a combined dynamic and static analysis. A pattern language is defined to enable the specification of dependencies as sequences of method invocations in the application code. Specifically, the sequences are patterns that constitute access to resources, e.g. databases, message queues, and control systems. We propose an algorithm for inferring application dependencies based on hybrid dynamic and static analysis that propagates information provided by dynamic analysis into the static analysis and back to the dynamic analysis. Empirical results from our implemented prototype are presented. back to list
Session: Compilers
A Backtracking LR Algorithm for Parsing Ambiguous Context-Dependent Languages Adrian D. Thurston and James R. Cordy, Queen's University Parsing context-dependent computer languages requires an ability to maintain and query data structures while parsing for the purpose of influencing the parse. Parsing ambiguous computer languages requires an ability to generate a parser for arbitrary context-free grammars. In both cases we have tools for generating parsers from a grammar. However, languages that have both of these properties simultaneously are much more difficult to parse. Consequently, we have fewer techniques. One approach to parsing such languages is to endow traditional LR systems with backtracking. This is a step towards a working solution, however there are number of problems. In this work we present two enhancements to a basic backtracking LR approach which enable the parsing of computer languages that are both context-dependent and ambiguous. Using our system we have produced a fast parser for C++ that is composed of strictly a scanner, a name lookup stage and parser generated from a grammar augmented with semantic actions and semantic `undo' actions. Language ambiguities are resolved by prioritizing grammar declarations. back to list A Framework for Reducing Instruction Scheduling Overhead in Dynamic Compilers Vikki Tang, Joran Siu, Alexander Vasilevskiy and Marcel Mitran, IBM Canada Ltd. Start-up time is a serious concern for high-availability applications such as web servers, transaction managers, and batch processes. Compilation time contributes directly to start-up costs in dynamic compilers. Up to 30% of compilation time is spent scheduling instructions in the IBM Testarossa just-in-time compiler. In this paper, we presented a framework that reduces scheduling time by up to 61% with little to no degradation in throughput performance. It does so by only scheduling regions of the code that can benefit the most from instruction scheduling. Such regions are identified by combining profile-directed feedback data, language semantics, and information generated by the register allocation phase. The effectiveness of the framework was evaluated using typical client-side applications, multi-threaded server applications and production-scale application servers on the IBM zSeries 990 and POWER4 platforms. Results show significant improvements in compilation time and startup time improvements without affecting overall throughput. back to list
Utilizing Field Usage Patterns for Java Heap Space Optimization Zhuang Guo, Jose Nelson Amaral, Duane Szafron, and Yang Wang, University of Alberta This research studies the characteristics of field usage patterns in the SpecJVM98 benchmarks. It finds that multiple object instances of the same class often exhibit different field-usage patterns. Motivated by this observation, we designed a heap compression mechanism that classifies object instances at runtime based on their field-usage patterns and eliminates unused fields to save space. To achieve the maximum space savings while minimizing the space and time overhead, our design combines three interrelated techniques in a novel manner: runtime object instance classification, field virtualization, and bidirectional object layout. An experimental evaluation reveals that this mechanism can reduce the maximum heap occupancy of SpecJVM98 benchmarks by up to 18% and 14% on average while keeping the application execution overhead low.

Session: Autonomic Computing
Requirements-Driven Design of Autonomic Application Software Alexei Lapouchnian, Yijun Yu, Sotirios Liaskos, and John Mylopoulos, University of Toronto Autonomic computing systems reduce software maintenance costs and management complexity by taking on the responsibility for their configuration, optimization, healing, and protection. These tasks are accomplished by switching at runtime to a different system behaviour - the one that is more efficient, more secure, more stable, etc. - while still fulfilling the main purpose of the system. Thus, identifying the objectives of the system, analyzing alternative ways of how these objectives can be met, and designing a system that supports all or some of these alternative behaviours is a promising way to develop autonomic systems. This paper proposes the use of requirements goal models as a foundation for such software development process and demonstrates this on an example. back to list Functionality Configuration for eHome Systems Ulrich Norbisrath and Christof Mosler, RWTH Aachen University New developments and decreasing costs of electronic appliances enable the realization of pervasive systems in our daily environment. In our work, we focus on eHome systems. The price of individual development and adaptation of the software making up these systems is one of the major problems preventing their large-scale adoption. In this paper, we introduce an approach built upon functionality composition for automatic service configuration in different environments. We transform the repetitive development process to a single development process followed by a repetitive configuration process. This configuration process is supported by our tool suite, the eHomeConfigurator. The result is a configuration graph, capable of describing dependencies and contexts of components in the eHome field. The tool suite is used to configure and deploy various services on different home environments. Compared to the classical development process, the effort for setting up eHome systems is reduced significantly. back to list Trust by Design: Information Requirements for Appropriate Trust in Automation Pierre Duez, University of Toronto; Michael Zuliani, IBM Canada Ltd; Greg A. Jamieson, University of Toronto Since the early stages of IBM's Autonomic Computing (AC) initiative, trust has been recognized as an important factor in the success of new autonomic features. If operators do not trust the new automated tools, they will not use them - no matter how useful or efficient they might be. Despite this stated awareness of trust as a major contributing factor to successful operator adoption of AC functionality (e.g., Telford et al., 2003), no clear process of explicitly designing for operator trust has emerged. The purpose of our research is to develop such a process, to provide a theoretically-grounded method for designing for appropriate trust in automation. We define "appropriate trust" as it is described in Lee & See (2004). Although they provide these categories of information, Lee and See (2004) do not provide a process by which the appropriate information might be identified for a given automated tool. We hypothesized that Cognitive Work Analysis (CWA; Vicente, 1999) might serve to provide a clear and definite list. CWA is a multi-stage analytic framework, developed for the analysis of complex sociotechnical systems. It is a constraint-based, formative analysis, which describes the realm of possible actions, rather than a single prescribed path. Several of the stages of CWA, we reasoned, could be adapted and applied to the problem of design for appropriate trust in automation. In this paper, we will introduce the model of trust in automation described by Lee and See (2004). We will also introduce CWA and describe the relevant stages of analysis. We will then describe how these stages can be applied to the question of trust in automation. Finally, we will present a case study from DB2, in which we applied CWA to identify specific information requirements for appropriate trust in Self-Tuning Memory Management, and used these findings to impact documentation and logging for this new automated functionality. back to list Back to top

Session: Program Analysis and Reverse Engineering
Static Analysis for Dynamic Coupling Measures Yin Liu and Ana Milanova, Rensselaer Polytechnic Institute Coupling measures have important applications in software development and maintenance. They are used to reason about the structural complexity of software and have been shown to predict quality attributes such as fault-proneness, ripple effects of changes and changeability. Traditional object-oriented coupling measures do not account for polymorphic interactions, and thus underestimate the complexity of classes and fail to properly predict their quality attributes. To address this problem Arisholm et al. define a family of \emph{dynamic coupling measures} that account for polymorphism. They collect dynamic coupling measures through dynamic analysis and show that these measures are better indicators of complexity and better predictors of quality attributes than traditional coupling measures. This paper presents a new approach to the computation of dynamic coupling measures. Our approach uses \emph{static analysis}, in particular \emph{class analysis}, and is designed to work on incomplete programs. We perform experiments on several Java components and present a precision evaluation which shows that inexpensive class analysis such as RTA computes dynamic coupling measures with almost perfect precision. Our results show that inexpensive static analysis can be used as a convenient and practical alternative to dynamic analysis for the purposes of computation of dynamic coupling measures. back to list All Code Coverage Is Not Created Equal: A Case Study in Prioritized Code Coverage Mechelle Gittens, Keri Romanufa, David Godwin, and Jason Racicot, IBM Canada Ltd. The increasing size and complexity of software systems has lead to increased challenges in evaluating code coverage [Kim]. As a result it now necessary to create weighted coverage approaches, indigenous to the development organization, to evaluate code coverage and its priorities in testing. This paper describes an approach to evaluating code coverage for a component of a large software application. The work allowed the test and development teams to determine the extent to which the most crucial functional and system testing had been done. back to list STAC: Software Tuning Panels For Autonomic Control Elizabeth Dancy and James R. Cordy, Queen's University One aspect of autonomic computing is the ability to identify, separate and automatically tune parameters related to performance, security, robustness and other properties of a software system. Often the response to events affecting these properties consists of changes to tuneable system parameters such as table sizes, timeout limits, restart checks and so on. One can think of these tuneable parameters as a set of knobs that can be tweaked or switched to adapt the system to environmental or usage changes. In many ways these tuneable parameters correspond to the switches and potentiometers on the tuning panel of many hardware devices. While modern systems designed for autonomic control may make these parameters easily accessible, in legacy systems they are often scattered or deeply hidden in the software source. In this paper we introduce Software Tuning Panels for Autonomic Control (STAC), a system for automatically re-architecting legacy software systems to facilitate autonomic control. STAC works to isolate tuneable system parameters into one separate visible module (the "control panel"), thereby facilitating autonomic control. The result is a maintainable, semantically equivalent program with a new architecture that effectively exposes tuneable system parameters for monitoring, manual control or automatic tuning. A proof-of-concept implementation of STAC using source transformation is presented along with its application to the automatic re-architecting of two open source Java programs. Use of the new architecture in monitoring and autonomic control is demonstrated using a number of examples. back to list
Session: Databases, Distribution and Concurrency
Workload Adaptation in Autonomic DBMSs Baoning Niu, Patrick Martin and Wendy Powley, Queen's University; Randy Horman and Paul Bird, IBM Canada Ltd. Workload adaptation is a performance management process in which an autonomic DBMS efficiently makes use of its resources by filtering or controlling the workload presented to it in order to meet its SLOs (service level objectives). This paper presents a framework and a prototype implementation of a query scheduler that performs workload adaptation in a DBMS. The system manages multiple classes of queries to meet their performance goals by allocating DBMS resources through admission control in the presence of workload fluctuation. The resource allocation plan is derived by maximizing the system utility that encapsulates the performance goals of all classes and their importance to the business. A first-principle performance model is used to predict the performance under the new resource allocation plan. Experiments with DB2 Universal Database are conducted to show the effectiveness of the framework. back to list Peer-to-peer Data Integration with Distributed Bridges Neal Arthorne and Babak Esfandiari, Carleton University This paper proposes an approach to collaborative and distributed data integration that relies on peer-to-peer data sharing and the creation of "bridges" between data sources. The bridges are themselves created and shared in a peer-to-peer manner, making this approach scalable and accessible to 3rd party applications. A case study of a distributed digital library is used to illustrate and validate the approach.
back to list Addressing Concurrency in Object-Oriented Software Development Jörg Kienzle, McGill University; Shane Sendall, Snowie Group SA E-business software systems are typically incorporated in complex concurrent and interacting business activities. Understanding the concurrent and interactive demands of the environment and tracing these requirements down to implementation is an important and necessary part of developing these types of systems. In this paper, we illustrate how concurrency concerns can be integrated in a UML-based software development method, and how these concerns can be incrementally refined from requirements to implementations. Our proposed approach not only offers a much needed holistic approach to concurrency in software development, but it also offers some novel techniques to describe concurrency concerns at each level of UML description.

Session: Model-Driven and Agent-Based Approaches
Integrating Scenarios, i*, and AspectT in the Context of Multi-Agent Systems Antonio de Padua Albuquerque Oliveira, Universidade do Estado do Rio de Janeiro, Pontificia Universidade Catolica do Rio de Janeiro, and York University; Luiz Marcio Cysneiros, York University; Julio Cesar Sampaio do Prado Leite, Eduardo Magno Lages Figueiredo and Carlos Jose P. Lucena, Pontificia Universidade Catolica do Rio de Janeiro Developing Multi-Agent Systems (MAS) calls for addressing different concerns. Some of them are general and related to the technology and others are particular to each collaborating agent. Our proposal aims to provide a more holistic approach to the construction of MAS. Integrating three different perspectives for information modeling we have achieved a more comprehensible way of dealing, early on, with the different concerns that are akin to MAS. In this paper we report our initial findings in integrating these three perspectives. We used a well known example: the Expert Committee, to illustrate the advantage of dealing with these three different perspectives. Our contribution relies on tackling different concerns in an integrated manner during the requirements definition of a MAS development. back to list Integrating Dynamic Views Using Model Driven Development R. Ian Bull, University of Victoria Model Driven Development is helping software developers rapidly engineer today's most sophisticated business applications. Tool support, such as the Eclipse Modeling Framework (EMF) and the newly announced Eclipse Modeling Project, provide a variety of support to software engineers. While these tools provide assistance during many stages of the software lifecycle, few tools exist to help the engineers design, generate and reason about complex, data centric user interfaces. This paper describes our Model Driven Visualization framework. This framework allows the Model Driven Development community to leverage several well established information visualization tools. Using model driven development techniques, we have provided a mechanism to rapidly prototype new visualizations from an application's data model. As an example, we have used this framework to generate a number of new, dynamically coordinated views for an EMF model that summarizes 87 years of National Hockey League statistics. back to list Automating Function Point Analysis with Model Driven Development Piero Fraternali and Massimo Tisi, Politecnico di Milano; Aldo Bongio, WebRatio Piazza Cadorna This paper describes a technique for automating the size estimation of software projects conducted using Model Driven Development methods. Specifically, an algorithm has been implemented for performing the function point count of a software project starting from its conceptual model. Differently from previous approaches, the proposed technique works on the same conceptual model that is used for producing the implementation, eliminating any unnecessary specification task. We evaluate the precision of the FP computation algorithm on a set of real-world projects and describe the implementation of the algorithm in a commercial Model Driven Development tool suite. back to list Back to top

Session: Security and Protection
Adaptiveness in Well-Typed Java Bytecode Verification Freeman Yufei Huang, Queen's University; C. Barry Jay, University of Technology Sydney, Australia; David B. Skillicorn, Queen's University Research on security techniques for Java bytecode has paid little attention to the security of the implementations of the techniques themselves, assuming that ordinary tools for programming, verification and testing are sufficient for security. However, different categories of security policies and mechanisms usually require different implementations. Each implementation requires extensive effort to test it and/or verify it. We show that programming with well-typed pattern structures in a statically well-typed language makes it possible to implement static bytecode verification in a fully type-safe and highly adaptive way, with security policies being fed in as first-order typed parameters, reduce the effort to verify security of an implementation itself and the programming need for new policies. Bytecode instrumentation can as well be handled in exactly the same way. The approach aims at reducing the workload of building and understanding systems, especially those of mobile code. back to list Packet Decoding using Context Sensitive Parsing Sylvain Marquis, Royal Military College of Canada; Thomas Dean, Queen's University; Scott Knight, Royal Military College of Canada Protocol tester is a project at RMC and Queen's that applies program transformation techniques to protocol data to evaluate the security of network applications. As part of this process, binary protocols are translated into a textual representation. This paper describes a translation process using context sensitive parser that eliminates the need to write custom code to decode each individual protocol. The parser is a template driven top down parser augmented by a constraint engine to implement the context sensitive restrictions. back to list On Approximate Matching of Programs for Protecting Libre Software Arnoldo Jose Muller Molina and Takeshi Shinohara, Kyushu Institute of Technology Libre software licensing schemes are sometimes abused by companies or individuals. In order to encourage open source development, it is necessary to build tools that can help in the rapid identification of open source licensing violations. This paper describes an attempt to build such a tool. We introduce a framework for approximate matching of programs, and describe an implementation for Java byte-code programs. First, we statically analyze a program to remove dead code, simplify expressions and then extract slices which are generated from assignment statements. We then compare programs by matching between sets of slices based on a distance function. We demonstrate the effectiveness of our method by running experiments on programs generated from two compilers and transformed by two commercial grade control flow obfuscators. Our method achieves an acceptable level of precision. back to list
Session: Web Services
Improving Web Site Search Using Web Server Logs Jin Zhou, Chen Ding and Dimitrios Androutsos, Ryerson University The global web search engine is quite popular and extensively used everyday, but the web site search engine is suffering from the poor performance. Since a web site is different from the whole web in link structure, access pattern, and data scale, it is not always successful as expected when the methods such as HITS, PageRank and DirectHit which improve the performance of web search are applied to the web site search. In this paper, we propose a novel algorithm to improve the retrieval performance by using web server logs. Web server logs are grouped into different sessions and the relationships of web pages in the session are analyzed according to their similarities. Then a new web page representation is generated based on sever logs. Anchor text is proved useful for web search, and it is used to create another representation. They are combined with text-based representation in the web site search. Two kinds of combination methods: combination of document representations and combination of ranking scores are investigated and experimented. Our experimental results show that the algorithm of using web server logs can improve the retrieval accuracy in terms of precision for four retrieval models we experimented on: Inference network model, Okapi model, Cosine Similarity model and TFIDF model. We also find that those models whose performance are better when only full text information is considered, such as Inference network and Okapi models, got less improvement from server log analysis than those whose performance are worse, such as TFIDF, Cosine Similarity models. back to list A Design Technique for Evolving Web Services Piotr Kaminski and Hausi Müller, University of Victoria; Marin Litoiu, IBM Canada Ltd. In this paper, we define the problem of simultaneously deploying multiple versions of a web ser-vice in the face of independently developed unsupervised clients. We then propose a solution in the form of a design technique called Chain of Adapters and argue that this approach strikes a good balance between the various requirements. The Chain of Adapters technique is particularly suitable for self-managed systems since it makes many version-related reconfiguration tasks safe, and thus subject to automation. back to list Legal Research Topics within Services Sciences Olli Pitkänen, Helsinki Institute for Information Technology HIIT The paper presents a study to define some of the most important legal topics that need to be included in the Services Sciences' research agenda. To analyze what sort of legal challenges the forthcoming services will have, an example of advanced service framework, MobiLife Service Framework, is presented. The framework highlights especially challenges in privacy and data protection and intellectual property rights. The analysis is complemented with a discussion on some other scenarios and examples that bring out legal issues. Based on the analysis, the paper concludes the most important legal topics that should be studied further in relation to services sciences in the fields of privacy and data protection, intellectual property rights, and contracts. back to list Back to top

Abstract: In the past, when it came to combatting cyber attacks, the main priority of companies was to maintain the operability of their computer networks. Today, businesses not only still try to keep their networks up and running, but they are also held accountable for the protection of their customers' private information that resides on their networks. Accommodating both these needs redefines what today's emerging threats are beyond just a technical examination of worms and viruses or security software and hardware.
During his presentation on emerging threats, Rob Clyde will examine the following: An overview of the internal and external pressures placed upon today's IT security environment in the form of cyber threats, evolving infrastructure, and compliance issues; the current state of threats and trends, including the shift in intent behind information security attacks, the increased speed between vulnerability to exploit, and threats that take the form of phishing, spyware, adware, Trojan horses, blended threats, and spam; the security challenges posed by increased adoption of broadband access and the use of wireless devices; solutions in the form of a proactive, holistic, and an integrated security approach; and the information security outlook moving forward.

Wednesday, October 19, 2005, 9:00 a.m. Topic: How Open Do You Need to Be?
Dr. Robert Sutor, Vice President of Standards and Open Source, IBM Corporation
Presentation material available here
Dr. Robert Sutor is the Vice President of Standards and Open Source for the IBM Corporation. In this role, he is responsible for driving and executing the cross-company business and technical strategy for open standards and open source, as they relate to software, hardware, service, vertical industries, and emerging markets. Previously, Sutor was Director of WebSphere Product and Market Management, which included ownership of the WebSphere Application Server, WebSphere MQ, and the WebSphere Business Integration product lines, as well as Web services and Service Oriented Architecture.
As a 22-year veteran of IBM, Sutor worked for 15 years in IBM Research, specializing in symbolic mathematical computation and Internet publishing. In 1999, he moved to the IBM Software Group and focused on jump-starting industry use of XML. This led to his position on the Board of Directors for the OASIS standards group and as the Vice Chairmanship of the ebXML effort (a joint OASIS/United Nations endeavor). Sutor then led IBM's industry standards and Web services strategy efforts.
Dr. Sutor is a frequent speaker on open standards, open source, WebSphere, Web services, and Service Oriented Architecture. He is widely cited in the press and was recently interviewed for the Harvard Business Review, CNET, eWeek, and InfoWorld.
Click here to take a look at Dr. Sutor's blog
Abstract: Open standards, open source, open collaboration, interoperability, and innovation: these five key themes of 2005, which each relate to and depend on the notion of "openness," will remain as central concepts over the next few years. Unfortunately, efforts to co-opt this notion of "openness" have essentially turned it into something that most rational people consider as more accurately reflecting the concept of "closed." In this discussion, Dr. Sutor will explore what openness should really mean, and how it relates to the above five themes. He will also be prescriptive about what you can do to help avoid the descent into the use of unnecessarily proprietary, locked-in applications, and document formats - unless you want to, of course!

We present a system that automatically generates Programming Contest CASCON 1999 tests to assess a designer's understanding from UML specifications. This technology can be used Central to automatically generate tests for end-users as well as software engineers. IBM alphaWorks CASCON 1998 IBM developerWorks Workflow-based Workplace - Generating Workplaces using Workflows in E-Commerce DB2 for Academics WebSphere for Academics A workflow enabling workplace is an enterprise application which integrates application and services to provide a working environment to assist users in performing workflow activities. Our research defines a framework that automates the design process of workflow enabling workplace. Our aim is to guide the users to perform the workflow activities, and to support users to complete these activities more efficiently and effectively.
Service Level Agreement - Mapping SLA Data for On Demand E-Business Successful software provisioning must ensure service commitments are based upon business objectives (e.g. cost-effectively minimizing the negative business impact of service level violations), and meet consumer service demands. We focus on the design of an on-line means of capturing Service Level Agreement (SLA) contract data as well as relationships with internal service management (SLM) policy data.
Autonomic Computing - Problem Determination Technologies The Autonomic Computing Toolkit along with other standalone applications and open-source standards will be used to demonstrate the advances made in the Autonomic Computing initiative. The specific tools/technologies that will be discussed are: Eclipse Log and Trace Analyzer, Web Log and Trace Analyzer, Common Base Events, and Generic Log Adapter.
Realtime Linux - Examining Various Realtime Approaches and Services This is going to discuss what realtime means, and various approaches to achieving it in the Linux Kernel. This includes an examination of services that are already available in a stock kernel, as well as experimental patches, such as the Robust Mutex Patch that provides mutexes with priority inheritance, the realtime preemption to obtain realtime latency. These services are necessary for languages that provide realtime extensions such as Java.
Policy-based Resource Reservation Manager - Individualised Reservations for Different Resources This research enables differentiated resource reservation policies. A single management tool uses the policies associated with the multiple resources and resource pools to provide a flexible management system. A policy can be modified accordingly when circumstances varies. This management tool cooperates with Tivoli Intelligent Orchestrator and contributes to furthering the Automatic Computing paradigm.
Autonomic Systems - Simulating Autonomic Mechatronics Systems This demonstration introduces a new method and environment for simulating autonomic mechatronics systems. Design errors in mechatronics systems can be extremely costly and have severe consequences.

COMPILATION TECHNOLOGIES
Instruction Scheduling - Using Constraint Programming Techniques The research project is an investigation into constraint programming techniques for instruction scheduling problem. Currently, instruction scheduling is being done heuristically in commercial and open source compilers. The primary goal of this work is to develop a constraint programming approach to the instruction scheduling problem that is optimal and fast.
Optimizing the JNI - Inlining Java Native Calls at Runtime The Java Native Interface (JNI) is used to bind Java applications to code written in low-level performance-critical native languages. Our research provides a strategy that eliminates JNI interoperability overheads by dynamically inlining native calls made by Java applications at runtime, optimizing inlined JNI callbacks and exposing inlined native code to aggressive Just-in- time compiler optimizations.
Speculative Commoning - Execution Profile Based Commoning for Space and Time We describe a compiler algorithm which performs partial redundancy elimination (a powerful type of common sub-expression elimination) by taking execution profiles into consideration. It can be configured to optimize for code speed, code compression, or a combination of both objectives. This work demonstrates an important and effective compiler transformation to CASCON Compiler Workshop audience.

DATABASE MANAGEMENT
DB2 Native XML Store - Native XML Support in DB2 Universal Database This exhibit introduces the new XML native store features of the next release DB2 UDB database. It includes the native XML storage capabilities, the XQuery language, and indexing of XML documents, and shows how these features are integrated into DB2.
BILCOM - Bi-Level Clustering Mixed Categorical & Numerical Data Clustering algorithms applied to biomedical domains so far, were not designed for mixed categorical and numerical data sets. We present the BILCOM algorithm for "Bi-Level Clustering of Mixed data types". BILCOM clusters data sets of objects having numerical attribute values, incorporating categorical attribute values representing semantic information on the objects.
ConQuer - Efficient Management of Inconsistent Databases Although integrity constraints have long been used to maintain data consistency, there are situations in which they may not be enforced or satisfied. In this demo, we showcase ConQuer, a system for efficient and scalable answers of SQL queries on databases that may violate a set of constraints.
Workload Adaptation - Towards Autonomic Workload Management in DBMSs To meet applications' service level objectives (SLOs), an autonomic DBMS needs to be able to control and filter the workload presented to it. In our approach, queries are first classified based on their SLOs and resource demand patterns. They are then scheduled based on their SLOs, the real performance goals being achieved and the current system resource utilizations.
DB2 POP - Progressive Query Optimization in DB2 This demo shows a newly prototype optimization technique allowing to interrupt and reoptimize certain DB2 queries while they are running.
SPIDER - Database Cleaning and Exploration The SPIDER tool is a declarative data cleaning client that can connect to any database and aid in improving the quality of the stored data. It contains a data exploration component (to aid spot the quality problems) and a data cleaning component (to correct them). It offers superior performance and ease of integration with applications.
Peer DB Management System - Data Sharing in the Hyperion Peer Database System This demo presents Hyperion, a prototype system that supports data sharing for a network of independent Peer Relational Database Management Systems PDBMSs). The nodes of such a network are assumed to be autonomous PDBMSs that form acquaintances at run-time, and manage mapping tables to define value correspondences among different databases.
Multiple View Grouping - Preprocessing for Fast Refreshing Multiple Views DB2 Design Advisor can handle multiple materialized view-refreshing. However this process becomes time consuming when the complexity and the number of views increase. To solve this problem we have implemented and tested a preprocessing technique that partitions the views into smaller groups and suggests a refreshing order for them.
Capacity on Demand - Extending TIO to Provision DB2 This demo shows autonomic resource allocation to alleviate database bottlenecks for an e- commerce server. A Tivoli objective analyzer determines when Quality of Service (QoS) to clients is likely to be violated. For predicted QoS violations, a workflow is triggered to allocate more database replicas to the e-commerce application.
Policy-Based Tuning in Autonomic Database Management Systems Autonomic Computing Systems will enable management according to business policies, such as a Workload Importance Policy. Economic models simplify the translation of high-level business policies into low-level tuning parameters. We utilize an economic model to implement various definitions of importance as a parameter for the allocation of buffer pool memory.

SOFTWARE ENGINEERING/TOOLS
Prism Query Language - Towards a General Concern Investigation Language Legacy code is of interest for many reasons: maintenance, refactoring, qualify measurement, and many more. These tasks can be made easier with a simple query language and the efficient processing of queries against very large code bases. The Prism Query Language (PQL) is an effort towards such a query system for Java systems.
TETE - A Test-Driven Framework for Source Transformation While the use of unit testing has been well documented for object-oriented and procedural languages, it is a relatively new concept in the area of source transformation. TETE is a source transformation environment for Eclipse centered around the use of rule-by-rule, type-by-type unit testing to improve the accessibility and transparency of programs written with the TXL source transformation language.
Clare – On Reverse Engineering Cross-Language Dependencies Software systems are often written in more than one programming language. During development, programmers often need to identify the dependencies between subsystems across language boundaries. We present a toolset that provides cross-language interoperability information for C/C++, Java, and Perl, implemented using the Eclipse platform.
Composing Components - Developing an Event-Based Composition Approach An event-based technique is one of the design-based approaches to compose software components that can be on a "publish-and-subscribe" paradigm. This work aims at designing and implementing a publish-and-subscribe system using Java RMI technology and IBM WebSphere MQ services for JMS. When a client component sends a request by posting a "help wanted" message, the server component enables publish-and-subscribe applications on demand and tailored to client's requirements.
Computer Intrusions - Prevention, Detection and Recovery Today application and system technologies such as phone networks and home communication systems (cable, games, etc.) are steadily being integrated to allow improved communication. These systems are prone to cross-application and cross-system attacks caused by malicious worms and viruses. In this exhibit, we will describe an integrated approach that prevents, detects and recovers from intrusions in these systems.
Quantifying Intrusiveness - A model for Intrusiveness in Pervasive Computing Helping users avoid intrusive interactions is important as interactions among people and computers increase. People are thus increasingly vulnerable to intrusive interactions. We analyze the problem for generic interactions, including factors that affect intrusiveness, and present an intrusion model to deal with it quantitatively.
Autonomic Computing - Policy-Based Orchestration Framework The objective of this research is to propose solutions to improve policy awareness of IBM Tivoli Intelligent ThinkDynamic Orchestration (ITITO).

Componentizing Framework - Decomposing Java Legacy Systems into Components This research work proposes a novel evolution methodology that integrates the concepts of features, and component-based software engineering (CBSE). It aims to decompose Java legacy systems into a list of components and consists of two major parts <1> identification of source code associated with features that need evolution and <2> creation of components.
Software Model-Checking - Verifying Real Programs with YASM Software model-checking is an automated technique which allows direct reasoning about programs written in languages such as C and Java. This exhibit presents the Toronto software model-checker Yasm, which allows checking various safety (e.g., can the program violate a desired invariant, overflow a buffer, etc.) and liveliness (e.g., can the program guarantee that every request will be fulfilled) properties. Yasm has been effectively applied to reasoning about network and security protocols.
Web Service Tools - IBM Rational Tools and the Eclipse Web Tools Platform IBM Rational Tools and the Eclipse WTP Platform project contain comprehensive, extensible tools for developing applications providing or using Web services based upon standards like SOAP, WSDL, UDDI, the WS-I Profiles and J2EE. This exhibit will demonstrate these tools and discuss the future of Web services.
Policy-Based Management - Data Centers and a High Availability Scenario This will appeal to attendees who are interested in autonomic computing, distributed systems, and policy management. A simulation is presented in which Tivoli Intelligent Orchestrator (TIO) handles a high availability failover scenario. TIO will be requesting guidance dynamically from an autonomic manager and acting in response to the decisions received.
Adaptive Scheduling - Dynamic Parallel Processing on IBM Clusters and Grids Grid computing with parallel applications requires dynamic and adaptive approaches to the job scheduling and to the corresponding middleware. The AlphaMeta lab presents corresponding approaches that make IBM clusters more suitable for grid environments and provide higher utilization of the resources, especially on machines with modern hyperthreaded and multi-core CPUs.

UML with NFR Framework - Incorporating Non-Functional Requirements in UML Models Few research works have focused on Non-Functional Requirements (NFRs) as first class requirements in a development process. Here we provide a mechanism to build a library/repository of reusable NFRs designed with UML notations and to integrate them with the UML model of software systems. This work uses standard XMI of UML model without proposing any extension to it. Such a novel framework is useful to integrate NFRs both in forward engineering and reverse-engineering processes.
Securing Sensitive Data - Protecting Sensitive Data Using Virtual Machine Isolation Spyware is a growing threat to the security of user data. This project uses Virtual Machine Monitors to isolate sensitive user data tokens such as passwords and credit card numbers. Applications have components that deal with such data extracted and placed in separate virtual machine monitors. We explore the viability of this approach.
An Awareness Mechanism in Support of Eclipse to Improve Requirements Change Propagation The poster displays the highlights of our current research on Awareness Mechanisms in support of Eclipse to improve Requirements Change Propagation. The research is a CAS project funded by NSERC and IBM and it is being hosted at the IBM Ottawa Labs.
Software Design Toolkit for Enterprise Applications Development To improve the efficiency of developing enterprise business applications, it would be advantageous to bridge the semantic gap between business process models (BPM) and the underlying software design models. We present a design toolkit for model-driven development where we automatically generate UML design artifacts from annotated and semantically- enriched BOM models.
Adaptive Monitoring - WebSphere Applications Applications running under WebSphere may exhibit anomalies because of a variety of causes: defects in application code, system changes, competing applications, etc. It is critical to both developers and operators to identify the cause of such anomalies. In this demo we will show how adaptive monitoring of the system can help identify causes of such anomalies.
Finding Core Architecture - Analysis of Evolving Software Systems Knowledge of the core architectural principles of a system's design can help maintainers to avoid architectural erosion of a system and evaluate its architectural design. Our demo presents a method for recovering the core architecture by analysing source code releases. Examples include MySQL and some of the history of Linux.
Workflow Extraction - A Framework for Workflow Redocumentation With the increase of the system size and rapid changes of the system functionality, extracting workflows from the source code and validating the correctness of the implementation and as- specified workflows become intractable tasks. We present an approach that utilizes multiple software artifacts to assist developers to verify the implementation and to update documents.
The MOD(ularity) Squad - Software Engineering, University of Victoria Through the application of state-of-the-art techniques such as aspect-oriented programming, the MOD(ularity) squad (researchers attempting to improve the modularity of system infrastructure software) plans to eliminate some of the deep structural flaws plaguing today's complex systems. This display will highlight our work-to-date in operating systems, virtual machines, and middleware.
Evaluating Policies and Their Effect on Software Process Performance Some policies may not have the expected effect as software development processes evolve. Through the use of questionnaires administered to team members, our method monitors weekly success indicators. The policies in use are then evaluated against these indicators, resulting in a summary of those policies thought to impact process performance.
Formal Semantics for UML - Back and Forth Between Formal and Lively Diagrams Formal semantics for UML class diagrams allows making the UML notation precise and much more suggestive w.r.t. its intended meaning.
Ptidej - A Tool Suite The Ptidej (Pattern Trace Identification, Detection, and Enhancement in Java) project aims at developing a tool suite to evaluate and to enhance the quality of object-oriented programs, promoting the use of patterns, at language-, design-, or architectural-level.

Autonomic Provisioning - Autonomic Resource Provisioning in a Grid Environment Jobs submitted to a Grid have a common deadline. A simulator is executed periodically to characterize the probability of missing the deadline. Input to the simulator is estimated from system measurement. The probability information is used to determine the minimum number of processors required such that no jobs will miss the deadline.
Modeling Product Lines - Mapping Features to Model Templates in IBM RSM Feature models are effective means for modeling common and variable characteristics of members in a system family. Mapping features to UML models gives them semantics and allows for automatic construction of system family members.
X-Site Search - Workplace Search System for Software Engineers This demo search system is the product of research into how software consultants search for information in the course of their work. We use relationships between work-tasks and document types (genres) to influence the ranking and push documents that are more task-applicable to the top of the hit list.
XRay Profiler - Performance Profiling for Eclipse Applications XRay is a performance analysis tool developed specifically for Eclipse-based applications. The software is tightly integrated with Eclipse and has been implemented as a plug-in that runs inside the target being profiled, making it aware of Eclipse-specific events. As Eclipse is an increasingly popular development platform for CASCON attendees, the need to profile, analyze and monitor resource usage and logic efficiencies is important

CASCON 2005 Experience in Using Business Scenarios to Assess COTS Components in Integrated CASCON 2004 Related links Solutions - BEST PAPER Sharon Lymer, IBM Toronto Ltd.; Wendy Qian Liu and Steve Easterbrook, University IBM University Relations of Toronto CASCON 2003 Programming Contest Central CASCON 2002 Constructing software by integrating commercial off-the-shelf (COTS) components is widely IBM alphaWorks practised, particularly in the IT service industry. For vendors of COTS components, CASCON 2001 IBM developerWorks requirements engineering is particularly challenging. To continually improve their products, DB2 for Academics vendors must identify and analyze problems that occur when their components are used in a CASCON 2000 WebSphere for Academics wide variety of integrated solutions, and they must anticipate new applications in which their components could be used. In this paper, we describe a scenario-based framework developed CASCON 1999 at the Software Group division of IBM Corporation (IBM SWG) The framework mimics the solution integration process for new business opportunities, allowing the development teams CASCON 1998 to evaluate their components, discover and resolve integration issues, and to surface new requirements for future releases. This paper describes the framework, gives an example of its use in a business scenario, discusses the experience of using this framework at IBM SWG, and relates the lessons learned. back to list
Automated Workplace Design and Reconfiguration for Evolving Business Processes Qi Zhang and Ying Zou, Queen's University; Tack Tong, Ross McKegney, and Jen Hawkins, IBM Canada Ltd.
In this ever-changing business environment, business processes are constantly being customized to reflect the up-to-date organizational structure and business objectives. Furthermore, technological updates and innovation also affect the way business is carried out. A workplace application provides an interactive electronic working environment that integrates software applications to assist users in performing their daily work more efficiently. It is challenging to maintain workplace applications as it often involves labor-intensive manual reconfiguration to adapt workplace applications to the changes to business processes. In this paper, we propose a workplace design framework that automatically analyzes business processes and generates workplace applications. Furthermore, it permits workplace reconfiguration at run time, which minimizes the interruption to users' work and simplifies deployment of business process changes to workplace applications. A prototype workplace application is designed and developed to demonstrate the effectiveness of the proposed framework. back to list
A Variability Management Process for Software Product Lines Edson Alves de Oliveira Junior, Itana Maria de Souza Gimenes, Elisa Hatsue Moriya Huzita Universidade Estadual de Maringá UEM); José Carlos Maldonado, Universidade de São Paulo (USP)
The software product line approach (PL) promotes the generation of specific products from a set of core assets for a given domain. This approach is applicable to domains in which products have well-defined commonalities and variation points. Variability management is concerned with the management of the differences between products throughout the PL lifecycle. It currently represents one of the challenges of the PL approach. The correct capture and representation of variabilities increase the number possible products that can be developed from a PL, thus increasing the return of investments of an organization in a PL adoption. Although several partial solutions for variability management can be found in the literature, there is still a lack of an explicit process that allows: identification, representation, delimitation, selection of implementation mechanisms, monitoring and variability tracing in a PL. This paper presents a UML-based process for variability management that encompasses such features. The process is illustrated with excerpts of a case study developed within the context of an existing PL for the workflow management system (WfMS) domain. The case study was developed based on the experimental software engineering concepts. The results have shown that the proposed process has made explicit a higher number of variabilities as compared to the existing PL process as well as offering a better support for variability tracing.
Session: Web Technology and E-Commerce diffX : An Algorithm to Detect Changes in Multi-Version XML Documents Raihan Al-Ekram, Archana Adma, and Olga Baysal, University of Waterloo This paper presents the diffX algorithm for detecting changes between two versions of an XML document. The identified changes are reported as a script of edit operations. The script, when applied to the first version of the XML document, will produce the second version. The goal is to optimize the runtime of mapping the nodes between the two versions and to minimize the size of the edit script. To achieve this goal an isolated tree fragment mapping technique is used, in order to iteratively identify the largest matching tree fragments between the tree representations, of the two versions of the document. The mapping technique is robust enough to handle differences in both the structure and the content of the two trees. The generated edit script from the mapping acknowledges the different order sensitiveness of element and attribute nodes of XML data model. The primitives for the edit script comprise both the atomic (node) and non-atomic (subtree) edit operations natural to XML document modification. The runtime of the algorithm is O(n^2). back to list
An Interactive System for Negotiation in E-commerce with Incremental User Knowledge Masrur Mia, S. P. Mudur, and Thiruvengadam Radhakrishnan, Concordia University In retail electronic commerce, incomplete user knowledge is a reality that must be addressed by electronic negotiation models and systems. This is particularly true in the case of multi- attribute products where valid product-configurations may require several constraints on attribute-values to be satisfied. Often, in such cases, the individual buyer refines the preferences for individual attributes as more and more information is exchanged during the negotiation process in an incremental fashion. In this paper, we consider how the negotiating parties can benefit from the incremental knowledge as the negotiation progresses. We assume the trust between the customer and merchant is such that the negotiation is for the purpose of seeking a mutually acceptable configuration of the product and its price. We have implemented a prototype system in which negotiation takes place between a human customer and multiple autonomous software agents, each carrying out sales operations on behalf of different merchants. We also describe the architecture of such an interactive multi-issue negotiation system on a distributed platform. The paper describes the various models we have used, and the multi-agent based software architecture that facilitates the interaction and the user interface. Our initial experiences with the prototype gives hope that e-commerce negotiation systems, in future, can benefit by making use of the incremental knowledge during the negotiation process. back to list
Event-Driven Response Architecture for Event-Based Computing Vijay Dheap, IBM Corporation; Paul A.S. Ward, University of Waterloo Service-based computing is rapidly replacing the more-traditional approaches to architecting distributed systems. The critical advantage of service-based architectures is that they require only a specification of protocol, and not of API. As such, they engender a significantly looser coupling than prior techniques, thus facilitating seamless collaboration across systems and across administrative domains. A Service-Oriented Architecture (SOA) is a middleware platform that provides a service- based computing environment. The "publish-find-bind" paradigm at the core of SOA enables the development of service-provision software separately from the development of service- consumption software. Closer observation of each aspect in this paradigm reveals that significant developer involvement is still required to assist the interaction between service provider and consumer. Developers of service-consumer software make the decision to employ a set of service providers at development time. Some SOAs provide facilities to programmatically search, bind, and even invoke services dynamically. However, it is still assumed that knowledge of both service providers and the service provided is known at development time, or the client must supply highly-detailed information about services they wish to use. This severely limits the possibility of dynamic run-time interactions among service providers and service consumers. In this paper we introduce EDRA, the Event-Driven Response Architecture for service-based computing. EDRA is a software framework that provides an infrastructure to dynamically select client-relevant service providers during run- time. Information services selected by EDRA on behalf of clients may send notification events in case of changes in the service. In such cases, our runtime will automatically process the notification based on a selection of user-choice, system defaults, and available action services. We have implemented a prototype of our framework, and show its operation in the domain of airline services.

Session: Aspect Oriented Technologies
Are Patches Cutting it? Structuring Distribution within a JVM using Aspects Jennifer Baldwin and Yvonne Coady, University of Victoria Distribution is hard to modularize. Consequently, its addition to a software system can jeopardize fundamental software engineering principles such as maintainability, understandability and evolvability. The distributed Java Virtual Machine (dJVM) is a cluster aware implementation of a JVM, designed specifically for evaluating distributed runtime support algorithms. A prototype implementation of the dJVM relies on a patch file applied to IBM's Jikes Research Virtual Machine (RVM), introducing distribution code into roughly 55% of the original 1500 files. An initial experiment using AspectJ to introduce this same distribution code as aspects demonstrates the benefits of a modularized approach versus the original patched approach. Preliminary results show that aspects can improve the overall quality of the implementation from a software engineering perspective. Specifically, the aspects improved the internal structure of distribution code and made its external interaction explicit. Additionally, consolidating and structuring previously scattered code reduced its size by a factor of three. back to list
Horizontal Decomposition of Prevayler Irum Godil and Hans-Arno Jacobsen, University of Toronto Aspect-Oriented Programming (AOP) is an emerging paradigm to modularize crosscutting concerns. A series of guidelines to refactor a software system into a common core and a set of variable functionalities have become known as Horizontal Decomposition (HD). In this paper we apply the HD principles to the Prevayler main memory database management system. The objective is to evaluate and refine these principles and to extract patterns of their use through a case study on a popular open-source software system. Our evaluation shows that HD reveals six crosscutting functionalities. The refactoring of these concerns yield 36 different configurations of the Prevayler system which were previously not possible. The refactoring also reduces the core Pre-vayler code size by 53%, demonstrates a decrease of coupling between core functionality components by 43%, and reduces the lack of cohesion of the core system by 71%. Given the heterogeneous nature of crosscutting displayed in Prevayler, the size and separation of concern metrics have not reduced for the overall refactored system, i.e., for the core composed with the aspects. A posterior analysis of the re-engineering process reveals 22 refactoring patterns that could be readily used by an automatic aspect refactoring tool. back to list
RoadMapAssembler: A New Pattern-Based J2EE Development Tool Jun Chen and Steve MacDonald, University of Waterloo The quality of a J2EE web application depends on both the correctness of the code as well as the efficiency and flexibility of its architecture. Unfortunately, the design and development process is complex and includes tedious coding details, making it error-prone. Part of the problem lies in the incomplete abstractions provided by the J2EE specification. The artifacts of the distributed system environment are still present in applications and cannot be ignored, notably interfaces for distributed objects, name space information, and deployment information. In this paper, we present the detailed design of our design-pattern-based J2EE development system, RoadMapAssembler. This system shows that a J2EE architectural framework can be generated by assembling a set of design patterns in an incremental fashion, exploiting our knowledge of pattern implementations and inter-pattern relationships. This same knowledge also allows us to generate code for the distributed system artifacts that pollute J2EE applications. We demonstrate these features through the development of an example J2EE application. back to list

Session: Software Understanding
On Generating Cognitive Patterns of Software Comprehension Adam Murray and Timothy C. Lethbridge, University of Ottawa This paper presents a research approach applied to the development of "cognitive patterns" in software comprehension. The approach involves observation of professionals in the field and the analysis of the resulting data. It is a "mixed methods" approach since it combines elements of specific research methods used in software engineering empirical research, and sociological qualitative research - specifically an approach called "grounded theory". We apply our combined approach to develop the basis for a theory of the ways people think when explaining and comprehending software. We have called the result "cognitive patterns". The approach involves videotaping of whiteboard activities as professional software engineers explain software, iterative coding of the video data, qualitative and quantitative analysis of the results, and generation of cognitive patterns from the categories. back to list
A Mechanism for Visualizing TCP-Socket Interactions Matthew Nichols and David Taylor, University of Waterloo TCP sockets are an important and ubiquitous construct. In order to better understand the behaviour of programs using TCP sockets, we have developed instrumentation that transparently collects information about each socket and graphically displays it as a single, unified view. This paper will describe the instrumentation which leverages an existing tool, POET (Partial-Order Event Tracer), to display the partial order derived from the socket operations. Several challenges in constructing this instrumentation will be discussed in detail. These challenges include accounting for relative delays in receiving information from the processes at two ends of the TCP stream, collating information from the two ends such that events can be sent to POET in a coherent form, and determining a useful and accurate visual representation of the communication sequences. back to list
Session: Compiler Technology
Learning Basic Block Scheduling Heuristics from Optimal Data Tyrel Russell, Abid M. Malik, Michael Chase, and Peter van Beek, University of Waterloo Instruction scheduling is an important step for improving the performance of object code produced by a compiler. The basic block instruction scheduling problem is to find a minimum length schedule for a basic block---a straight-line sequence of code with a single entry point and a single exit point---subject to precedence, latency, and resource constraints. Solving the problem exactly is known to be difficult, and most compilers use a greedy list scheduling algorithm coupled with a heuristic. The heuristic is usually hand-crafted, a potentially time- consuming process. In contrast, we present a study on automatically learning good heuristics using techniques from machine learning. In our study, a recently proposed optimal basic block scheduler was used to generate the machine learning training data. A decision tree learning algorithm was then used to induce a simple heuristic from the training data. The automatically constructed decision tree heuristic was compared against a popular critical-path heuristic on the SPEC 2000 benchmarks. On this benchmark suite, the decision tree heuristic reduced the number of basic blocks that were not optimally scheduled by up to 55\% compared to the critical-path heuristic, and gave improved performance guarantees in terms of the worst-case factor from optimality. back to list
Mixed Mode Execution with Context Threading Mathew Zaleski, Marc Berndl and Angela Demke Brown, University of Toronto Interpreters are widely used to implement portable language runtime environments. Programs written in these languages may benefit from performance beyond that obtainable by optimizing interpretation alone. A modern high-performance mixed-mode virtual machine (VM) includes a method-based Just In Time (JIT) compiler. A method-based JIT, however, requires the up-front development of a complex compilation infrastructure before any performance benefits are realized. Ideally, the architecture for a mixed-mode VM could detect and execute a variety of shapes of hot regions of a virtual program. Our VMarchitecture is based on context threading. It supports powerful, efficient instrumentation and a simple framework for dynamic code generation. It has the potential to directly support a full spectrum of mixed-mode execution: from interpreted bytecode bodies, to specialized bytecode generated at runtime, to traces, to compiled methods. Further, it provides the necessary tools to detect these regions at runtime.
We extended two VMs, SableVM and the OCaml interpreter with our infrastructure on both the P4 and PPC. To demonstrate the power and flexibility of our infrastructure we compare the selection and dispatch effectiveness for three common region shapes: whole methods, partial methods, and SPECL traces. We report results for a preliminary version of our code generator which compiles a region into a sequence of direct calls to bytecode bodies.

Session: Autonomic Computing
Emotions as a Metaphor for Altering Operational Behavior in Autonomic Computing Ricky Chandarana and David B. Skillicorn, Queen's University The ability to change operational behavior in response to changes in both external and internal environment is an important aspect of autonomic computing. Managing such behavioral changes is challenging. We propose emotions as a useful mechanism for understanding the structure and use of behavioral changes, and present the design and implementation of the Emotion System, a stand-beside environment for ordinary programs. Both the metaphor and the implementation are designed to make it easy for software developers to integrate autonomic computing into their systems. back to list
Tracking Time-Varying Parameters in Software Systems with Extended Kalman Filters Tao Zheng, Jinmei Yang, and Murray Woodside, Carleton University; Marin Litoiu and Gabriel Iszlai, IBM Canada Ltd. Autonomic control of a service system can take advantage of a performance model only if a way can be found to track the changes in the system. A Kalman Filter provides a framework for integrating various kinds of measured data, and for tracking changes in any time-varying system. This work evaluates the effectiveness of such a filter in tracking changes in performance parameters of a software system that occur at different rates and amplitudes. The time-varying system is a Web application deployed in a data centre with layered queuing resources, in which parameter variations happen at random instants. The tracking filter is based on a layered queuing model of this system, with parameters representing CPU demands and the user load intensity. Experiments were performed to evaluate the effectiveness of the filter in tracking the changes, and the requirements for the filter settings for fast and slow variations in the parameters. The target application is autonomic control of a service centre. back to list Back to top

Session: Security, Privacy and Trust
Eliciting Confidentiality Requirements in Practice Seda Güerses, Humboldt University; Jens H. Jahnke, Christina Obry and Adeniyi Onabajo, University of Victoria; Thomas Santen, TU Berlin ;Morgan Price, University of British Columbia Confidentiality, the protection of unauthorized disclosure of information, plays an important role in information security of software systems. Security researchers have developed numerous approaches on how to implement confidentiality, typically based on cryptographic algorithms and tight access control. However, less work has been done on defining systematic methods on how to elicit and define confidentiality requirements in the first place. Moreover, most of these approaches are illustrated with simulated examples that do not capture the richness of real world experience. This paper reports on our experiences eliciting confidentiality requirements in a real world project in the health care area. The method applied originates from the M.Sc. thesis of one of the authors and is still considered work in progress. Still, valuable insight into issues of confidentiality requirements engineering can be gained from this case study and we expect that its publication will become a basis for discussion and the definition of a further research agenda in this area. back to list
A Secured Hierarchical Trust Management Framework for Public Computing Utilities Arindam Mitra, University of Manitoba; Ranganath Udupa and Muthucumaru Maheswaran, McGill University This paper presents a hierarchical (two-layered) trust management framework for very large scale distributed computing utilities where public resources provide majority of the resource capacity. The dynamic nature of these utility networks introduce challenging management and security issues due to behavior turnabout, maliciousness and diverse policy enforcement. The trust management approach offers interesting answers to such issues. In our framework, the lower layer computes local reputation for peers within their domain based on individual contribution, while the upper layer combines the local reputation with that of its domain's (as perceived by other domains) to compute the peer's global trust. Simulation results show that the hierarchical scheme is more scalable, highly robust in hostile conditions and capable of creating rapid trust estimates. Features of the framework include: (a) ability to carry forward local behavior trends, (b) autonomous domain-based policing, (c) high cohesiveness with the resource management system, and (d) securely exposing the trust evaluation operations to peers (i.e., the subjects of the evaluation process). A detailed analysis of the threats/attacks that the framework could be subjected is presented along with counter-measures against the attacks. back to list
Detecting Unusual Email Communication Parambir S. Keila and David B. Skillicorn, Queen's University Deception theory suggests that deceptive writing is characterized by reduced frequency of first-person pronouns and exclusive words, and elevated frequency of negative emotion words and action verbs. We apply this model of deception to the Enron email dataset, and then apply singular value decomposition to elicit the correlation structure between emails. Those emails that have high scores using this approach include deceptive emails; other emails that score highly using these frequency counts also indicate organizational dysfunctions such as improper communication of information. Hence this approach can be used as a tool for both external investigation of an organization, and internal management and regulatory compliance. back to list
Session: Database Technology
Scalable Database Replication through Dynamic Multiversioning BEST STUDENT PAPER Kaloian Manassiev and Cristiana Amza, University of Toronto We scale the database back-end in dynamic content web servers on a set of database replicas while maintaining strong consistency. This is contrary to conventional wisdom in replicated databases which says that one could have either strong consistency or scalability, but not both. The key to scaling is a novel integrated fine-grained concurrency control and data replication algorithm called Dynamic Multiversioning that provides fine-grained distributed concurrency control at the level of a memory page across a database cluster. We exploit the different distributed data versions that naturally come about as a result of asynchronous data replication in order to increase concurrency by running conflicting transactions in parallel on different replicas. At the same time, the serialization order is determined using fine-grained concurrency control at a master database and enforced through a version-aware scheduling technique. Our technique does not put any crucial data in the scheduler, which permits easy reconfiguration, without loss of data, in the case of single-node failures of any node in the system. Our measurements show near-linear scaling up to 8 databases for the browsing, shopping and even for the write-heavy ordering workload of the industry-standard e-commerce TPC-W benchmark.

Online Data Migration for Autonomic Provisioning of Databases in Dynamic Content Web Servers Gokul Soundararajan and Cristiana Amza, University of Toronto This paper introduces an efficient data migration technique for provisioning new databases to workloads in dynamic content servers. Although many solutions for database replication exist, an efficient method for joining new replicas to a running system has not been implemented. We propose and implement a data migration algorithm that allows quick addition of replicas with minimal disruption of transaction processing. Furthermore, we show that our approach can also be used for fault management and re-integrating failed databases. We investigate our algorithm for transparent provisioning in the database tier using the TPC-W e-commerce benchmark and the Rubis online auction benchmark. We demonstrate that our technique provides quality of service under different load and failure scenarios. back to list
DBmbench: Fast and Accurate Database Workload Representation on Modern Microarchitecture Minglong Shao, Anastassia Ailamaki, and Babak Falsafi, Carnegie Mellon University With the proliferation of database workloads on servers, much recent research on server architecture has focused on database system benchmarks. The TPC benchmarks for the two most common server workloads, OLTP and DSS, have been used extensively in the database community to evaluate the database system functionality and performance. Unfortunately, these benchmarks fall short of being effective in microarchitecture and memory system research due to several key shortcomings. First, setting up the experimental environment and tuning these benchmarks to match the workload behavior of interest involves extremely complex procedures. Second, the benchmarks themselves are complex and preclude accurate correlation of microarchitecture- and memory-level bottlenecks to dominant workload characteristics. Finally, industrial-grade configurations of such benchmarks are too large and preclude their use in detailed but slow microarchitectural simulation studies of future servers. In this paper, we first present an analysis of the dominant behavior in DSS and OLTP workloads, and highlight their key processor and memory performance characteristics. We then introduce a systematic scaling framework to scale down the TPC benchmarks. Finally, we propose the DBmbench consisting of two substantially scaled-down benchmarks: mTPC-H and mTPC-C that accurately (> 95%) capture the processor and memory performance behavior of DSS and OLTP workloads. back to list

Scheduling Functional Regression Tests in IBM DB2 Products Edward Xia and Igor Jurisica, University of Toronto; Julie Waterhouse and Valerie Sloan, IBM Canada Ltd. Functional Regression Testing (FRT) is performed to ensure that a new version of a product functions properly as designed. In a corporate environment, the large numbers of test jobs and the complexity of scheduling the jobs on different platforms make performance of this testing an important issue. A grid provides an infrastructure for applications to use shared heterogeneous resources. Such an infrastructure may be used to solve large-scale testing problems or to improve application performance. FRT is a good candidate application for running on a grid because each test job can run separately, in parallel. However, experience indicates that such applications may suffer performance problems without a proper cost- based grid scheduling strategy. The Database Technology (DBT) Regression Test Team at IBM conducts the FRT for IBM DB2 Universal Database (DB2 UDB) products. As a case study, we examined the current test scheduling approach for the DB2 products. We found that the performance of the test scheduler suffers because it does not incorporate cost-dependent selection of jobs and slaves (testing IDs). Therefore, we have replaced the DB2 test scheduler with one that estimates jobs‚ run times, and then chooses slaves using those times. Although knowing a job‚s actual run time is difficult, we can use case-based reasoning to estimate it based on past experience. We create a case base to store historical data, and design an algorithm to estimate new jobs‚ run times by identifying cases that have executed in the past. The performance evaluation of our new scheduler shows a significant performance benefit over the original scheduler. In this paper, we also examine how machine specifications, such as the number of slaves running on a machine and the machine speed, affect application performance and run time estimation accuracy.

Universal Access Architecture for Digital Libraries Francisco Alvarez-Cavazos, Roberto Garcia-Sanchez, David Garza-Salazar, Juan C. Lavariega, Lorena G. Gomez, and Martha Sordia, ITESM, Campus Monterrey In this paper we present a universal access architecture for digital libraries. Our architecture supports traditional fixed clients and mobile clients addressing the connection adaptation and limited resources challenges presented by mobile devices. We describe the requirements of universally available personal digital libraries and illustrate their applicability with a user scenario. These requirements are addressed by our universal access architecture, which targets to support multiple device access, including mobile devices. The main components of the architecture are the Client-Side Applications, the Data Server and the Mobile Communication Middleware (MCM). Our work has focused on the mobile connection support provided by the interaction of mobile clients with the MCM, obtaining a constant response rate in spite of variability of network conditions. The architecture of a mobile software client that benefits from these mechanisms is described and supplemented with implementation notes showing how—in spite of the limited computing resources of mobile devices—it can interact with a data server that has not been designed to support client mobility via adaptation techniques implemented in a middleware. back to list
SCL: A Language for Security Testing of Network Applications Sylvain Marquis, Royal Military College of Canada; Thomas R. Dean, Queen's University; Scott Knight, Royal Military College of Canada Security of network applications has become increasingly important in the past several years. Syntax-based testing is a black box, data driven testing technique, for applications for which input can be described formally. SCL is a component of Protocol Tester, a project at RMC and Queen's, that uses syntax-based testing to evaluate the security of network applications. As a language, SCL can describe the syntax and the semantic constraints of a given protocol, constraints that pertain to the testing of network application security. This paper describes how SCL captures the input syntax of a network application including both syntax and semantic constraints. Standard reverse engineering and program comprehension techniques are used to extract a detailed model from the description. This model can be used to automate the selection and generation of test cases in Protocol Tester. back to list

Topic: Wireless Access to Corporate Data
David Yach, Senior Vice President of Software at Research In Motion
David is Senior Vice President of Software at Research In Motion. David oversees and manages the development of software that has helped Research In Motion become a world leader in the mobile data communications market. With a Bachelor's degree in Math and an MBA, David has a solid portfolio of technical, operational and managerial experience from several senior-level positions. Prior to joining Research In Motion, David held the position of Vice President and Chief Architect at Sybase Inc
Abstract: People have an increasing need to have access to information. With the vast amount of information available inside the corporation, most access techniques that have been developed over the years are based on parameters that are relevant to the 'connected' world. With the prevalence today of wireless devices such as cell phones and BlackBerrys, information must now be delivered quickly and efficiently to mobile users, as these users have had their urge for information fostered in connected high-speed environments.
In his keynote, David will discuss the challenges of software development in this rapidly expanding environment of wireless and occasionally connected devices. Enabling wireless access to corporate data adds new constraints. This presentation will explore those constraints and the techniques that are being used to overcome these challenges, as well as identify the potential areas where future research is needed.
Topic: Specifying and Enforcing Software Architectures
Bran Selic, IBM Distinguished Engineer
Bran Selic is an IBM Distinguished Engineer at IBM Rational Software and an adjunct professor of computer science at Carleton University in Ottawa, Canada. He has over 30 years of experience in industry in designing and implementing large-scale industrial software systems. Bran pioneered the application of object technology and model-driven development methods in real-time applications. He has participated in the definition of the UML standard since 1996 and is currently leading an OMG team responsible for finalizing the 2.0 revision of the standard.
Software architecture is fundamental for a number of reasons: it is the key to understanding complex systems, it serves as a blueprint that drives implementation, and, perhaps most importantly, it determines a system’s ability to evolve in response to new requirements. In this talk, we first list the requirements for an architectural description language; that is, a language that can be used to specify software architectures. Next, we describe some recent developments in the Unified Modeling Language that allow it to be used both as an architectural description language and as an architectural enforcement facility. Enforcement is particularly significant because of “architectural decay” – the phenomenon of gradual but potentially dangerous deterioration of software due to low-level maintenance activity.
Topic: Research Challenges of Autonomic Computing
Jeffrey O. Kephart, Mgr., Agents and Emergent Phenomena IBM Thomas J. Watson Research Center
Jeffrey O. Kephart manages the Agents and Emergent Phenomena group at the IBM Thomas J. Watson Research Center and chairs IBM's Autonomic Computing Advisory Board. His research focuses on the application of analogies from biology and economics to massively distributed computing systems, particularly in the domains of autonomic computing, e-commerce, antivirus, and antispam technology. His research efforts on the design of a digital immune system and on economic software agents have been publicized in publications such as The Wall Street Journal, The New York Times, Forbes, Wired, Harvard Business Review, IEEE Spectrum, and Scientific American. Kephart received a BS from Princeton University and a PhD from Stanford University, both in electrical engineering.
Abstract: The increasing complexity of computing systems is beginning to overwhelm the capabilities of software developers and system administrators to design, evaluate, integrate, and manage these systems. Major software and system vendors such as IBM, HP and Microsoft have concluded that the only viable long-term solution is to create computer systems that manage themselves.
Three years ago this month, IBM launched the autonomic computinginitiative to meet the grand challenge of creating self-managing systems. Although much has already been achieved, it is clear that a worldwide collaboration among academia, IBM, and other industry partners will be required to fully realize the vision of autonomic computing. I will discuss several fundamental challenges in the areas of artificial intelligence and agents, performance modeling, optimization, architecture, policy, and human-computer interaction, and describe some of the initial steps that IBM and its partners in academia have taken to address those challenges.

Abstract: We are on the crest of a new wave in computing. The rapid increases in computer processing, storage and bandwidth have made it possible to capture and distribute vast quantities of data. This has led to the demand for more intuitive tools for searching, retrieving, synthesizing, and understanding these data. A decade ago, this problem was called the data mining, and led to the development of new analytical tools to find patterns in numerical data. In the last few years, powerful new algorithms have been developed to search textual data, especially on the internet. But, this is just the tip of the iceberg. Increasingly, businesses are capturing image, video, and geometric data. The business value is not only in "mining" these unstructured data, but in allowing people to explore patterns across different data types. This presentation will provide a look at the exploding world of unstructured data, application domains that are driving a new focus on information semantics, and the shift toward creating solutions that are better matched to the visual and cognitive capabilities of human decision makers.
Topic: Aspect-Oriented Programming
Gregor Kiczales, Professor of Computer Science, University of British Columbia
Gregor Kiczales is Professor of Computer Science at the University of British Columbia. Previously he was a Principal Scientist at the Palo Alto Research Center where he led the team that developed aspect-oriented programming and AspectJ. AspectJ is the de facto standard for AOP in Java, and is the subject of four books and numerous articles.
Prior to aspect-oriented programming he worked extensively in reflection and object-oriented programming. He is a co-author, with Danny Bobrow and Jim des Rivieres of The Art of the Metaobject Protocol, a key work in reflection and metaobject protocols.
Abstract: Aspect-oriented programming (AOP) has emerged as a new technology for improving the quality and value of software.
AOP gives us a new unit of modularity - the aspect - with which we can design, implement and deploy software. Aspects are crosscutting elemenets of a system's design. They include synchronization policies, error handling, resource management, common design patterns, and many other issues.
Adoption of AOP is happening very quickly, because developers have recognized that it can be done incrementally, and that thinking in terms of aspects can improve your software development whether you use an AOP language or not.
In this talk I will present the key ideas of AOP, and discuss the impact it can have on software development and quality.

The tool supports agent- and goal-oriented analysis for strategic business requirements engineering and software systems and architectures design. OpenOME bridges the Semantic Web ontology with the knowledge representations in requirements modelling languages.
Software Model-Checking Automated verification has been promoted as a replacement for testing. Unfortunately, verification required that models be extracted from code before any analysis can commense. Software model-checking enables direct verification of code. The demo showcases the Toronto software model-checker YASM.
Runtime Verification Runtime Verification of software is considered a viable enhancement of testing. A correctness property is specified in temporal logic, and the analysis is performed while the program is running or simulated. This demo showcases the use of the software model-checker YASM as a runtime verifier.

ACSE: Adoption-Centric Software Engineering Adoption-Centric Software Engineering (ACSE) explores approaches where software engineering tools and practices are implemented as extensions of commercial-off-the-shelf (COTS) products. These extensions are often unimagined by the original designers of the COTS software. This tool-building approach complements traditional software development with techniques for designing, implementing, and testing systems involving COTS product integration.
Application of Fuzzy Logic (FL) for effective Project Management (PM) PM is integral for project successes; hence numerous CASE tools have been developed. PM tools employing fuzzy logic aid in cost/development/size estimations. However, they cannot be utilized for all PM knowledge areas. The proposed approach is applicable to all PM knowledge areas for effective PM, ensuring higher success rates.
Agile exploration of software architectures Our exhibit will demonstrate software that allows software developers and researchers to interactively study, modify and repair software architectures of complex systems.
Workflow Synchronization Business applications are subject to continuous change. Over time, the associations between business workflows and source code are broken and revisions made thereafter are inconsistent. We present an approach to model synchronization where we maintain consistency between process models extracted from the customer business workflow and the underlying source code.
Workplace Personalization A workplace is a working environment in which a role can access all the information, applications, and services needed to perform a set of work inside an organization. With the advancement of Portal technology, developing a role-based, personalized workplace becomes possible. We present an approach to automatically generate a workplace from existing business workflows that provides a role with a unified view for accessing business activities.
Model Driven Business Process Recovery A business process encapsulates the delivery of a sequence of tasks, starting from accepting a service request and ending at the completion of the service. We propose a model-driven business process recovery framework that captures the features representing a business process. This framework utilizes static tracing techniques and a number of heuristics to map source code entities to high-level business process entities.
Calibrating Software Size in Function Points using Neuro-Fuzzy Function Points is a well accepted standard for sizing software independent of languages. Its analysis methodology has now upgraded to IFPUG v4.1, but its parameter value remain the same since its birth in 1979. We are calibrating parameters using Neuro-Fuzzy technique, which proves to outperform original Function Points in giving better results of estimating software project effort.

Pressure Widgets Current user interface widgets typically assume that the input device can only provide x-y position and binary button press information. However, other inputs such as the continuous pressure data provided by styli on tablets are rarely used. We explore the design space of using the continuous pressure sensing capabilities of styluses to operate multi-state widgets.
Influence of Site Maps We evaluated the influence of site maps in an information-searching task. Users performed better with a constantly visible site map and they were faster with clickable links. The benefits were more pronounced with large sites. A visible, clickable site map is recommended when designing a web site or hypertext system.

Energy-efficient query processing in sensor networks Sensor networks consist of nodes with the ability to measure, store, and process data, as well as to communicate wirelessly. Users can issue queries over the network to retrieve information from sensor nodes, in applications such as environmental monitoring and warehouse management. We discuss several solutions for energy-efficient query processing, an essential problem due to the limited power supply each sensor node has.
Automatic Statistics Collection in DB2 UDB We present the new Automated Statistics Collection (ASC) feature of DB2. In a large database, Correlation and cardinality estimation errors, cause a slow running query. However, after the completion of an independent workload enabling statistics profiling, the DBMS will automatically correct these errors, resulting in a greatly improved execution plan and running time for the same statement.
Generative programming meets autonomous databases: generating optimal databases customized to applications Our database framework allows us to generate instances of databases based on selected configuration parameters. A usage profile for an application describes the set of queries and their frequency, as well as size and distribution of the data. Based on the usage profile, we select an optimal configuration and generate a customized database.
Visual queries for graph databases for genomics Novel paradigms for posing queries to genomics databases include visual graph queries, visual QBE (query-by-example), and visual ontology-based queries. Our prototype supports visual queries using GraphLog against a genomics database in mySQL using CORAL as the execution engine. Future work includes optimization of queries for graph databases.

WEB TECHNOLOGY
Java, web pages and DB2 Building, maintaining, and hosting web pages in a simple and effective manner for ease of managment of several research projects. Java Applet for give site/project administrators the ability to build and update web pages as required. The applet interfaces with DB2 to store the information of web pages: leveraging DB2's storage and security features. Also an easy to use plugin system, so additional features as required. Feature Interactions among Web Services Composition is inherent in the notion of web services. The more web services can potentially interact, the harder it is for services to interwork as desired. We propose an approach for modeling interactions as feature interactions, their detection, and resolution. It combines goal- oriented analysis (GRL) and scenario modeling (UCM).
Query Translation of SQL to EJB QL With the introduction of EJB 2.0 and the standard EJB query language (EJB-QL), when the EJB container is upgraded, vendor specific queries in entity beans have to be translated into EJB- QL. The SQL to EJB-QL translator is designed to translate the SQL statements in finder methods in CMP1.X entity beans to EJB-QL.
Web Services Searching With the growing large number of web services, it is no longer adequate to locate a web service by searching its name or by browsing a UDDI directory. We introduce a web service searching prototype that can locate web services by comparing all available information encoded in web services, such as operation name, its input and output types, the structure of the underlying XML Schemas, and semantics of element names.
A Tool for Formal Program Refinement Logical reasoning helps certain tasks in programming if made practical. We show our reasoning environment to this end. Unlike similar tools, this one is an extension to a common IDE (Eclipse), opening many possibilities of integration with programming workflow (most will be future work), thus serving programmers usefully and directly.

Dead-Path-Elimination - Walking the EMF model of BPEL4WS We would like to demo a tool that we developed. It detects if dead-path-elimination, a key ingredient of BPEL4WS, may give rise to (unexpected) side effects. If it does, the tool depicts in the graphical editor of BPEL4WS where these side effects may occur.
J2EE Application Development for the Enterprise Systems- Java Connector Tooling We will use the Java Connector Tooling to generate the Java code based on the CICS COBOL program. We will deploy the web application to Test enviornment. We will also turn the java bean into a webservice and generate a front-end client Test JSP to access thew webservice. J2EE developers will be able to experience the ease of J2EE development and witness the powerful tooling that embraces all the new underlying technologies (WRD,Dynamic wizard,content assist ..) that we have.
Optimal Instruction Scheduling The primary goal of this work is to develop a constraint programming approach to instruction scheduling and to register allocation for a multiple-issue processor that is both optimal and fast enough to be incorporated into a production compiler. An optimal approach may be useful for improving compiler's performance.
Prism: Prism is research in software modularity For aspect oriented programming, aspect mining of legacy software bases are vitally important in the understanding of the semantics of domain-specific aspects, architectural improvement through refactorization, as well as designing new AOP systems. Prism is designed to provide tool support for aspect discovery in large code bases through powerful and flexible compositions of queries about the characteristics of aspects.
Aspect Refactoring Verifier Aspect refactoring verifier accompanies the Eclipse AspectJ development environment to provide an integrated verification environment to assist correct source-code refactoring with aspects. The verification is conducted at the source code level and currently supports join point comparisons.

Since joining Google in 2000, Dr. Craig Nevill-Manning has been researching and developing precision search technology for the Google search engine. Nevill-Manning is also a vital contributor to the technological infrastructure used to support AdWords, Google's self-service advertising program, and is developer of the Google Glossary, a tool for finding definitions to words, phrases and acronyms available through Google Labs (http://labs.google.com/glossary)
Nevill-Manning joined Google from the Computer Science Department of Rutgers University, where he conducted research in data compression, information retrieval and computational biology. Prior to Rutgers, Nevill-Manning was a post-doctoral fellow in the Biochemistry Department of Stanford University. While at Stanford, Nevill-Manning wrote eMOTIF, a software suite to identify the role of particular proteins within cells.
Nevill-Manning's published 41 research papers and received a National Science Foundation career grant. A native of New Zealand, Nevill-Manning earned a BS in Computer Science from Canterbury University and a PhD in Computer Science from Waikato University.
Abstract: Google faces two large technical challenges: ensuring that our search results are as relevant as possible, and serving hundreds of millions of queries in a fraction of a second at a reasonable cost. To solve the first problem, we perform an offline matrix computation to produce PageRank, a query independent measure of page reputation, and combine it with more traditional query-specific scoring. To solve the distributed computing problem, we use tens of thousands of commodity PCs and highly fault-tolerant software. I will discuss some details of these solutions, and also share some interesting statistical tidbits about search and the web.

Don Chamberlin, IBM Fellow, Query Languages
A research staff member at IBM's Almaden Center in San Jose, Calif., Don Chamberlin and Ted Codd invented SQL, the language that became the standard for relational databases. First described in a paper authored by Codd in 1970, SQL-based relational databases hit the market nine years later, after user-interface and other technology issues were resolved.
Now Chamberlin is working on what he and much of the industry hope will be a new standard: Xquery, which would be used for querying XML (Extensible Markup Language) databases. "We need a new query language every 25 years. I've timed my life very carefully so I can get in on two of these cycles," jokes Chamberlin. The database pioneer is also a member of the IBM Academy of Technology.
Xquery is designed to handle data in XML format, which packages data along with its metadata- -that is, the data about the data. To help streamline their operation, relational databases strip out the metadata, which is stored separately.

Thursday, October 9 - 9:00 a.m. Topic: Autonomic Computing: The technology behind the message
Ric D. Telford, Director, Autonomic Computing Technology, IBM Software Group
Ric Telford's professional business career highlights 19 years of software development experience and is noted for bringing innovative approaches to the design and development of key software technologies. Telford joined IBM in 1983, as a developer for PROFS in their software lab in Dallas, TX. During his tenure at IBM, Telford has played a number of key roles in numerous software initiatives for IBM, including service provider solutions, imaging products unit, networking software, security software, and software mobility products. He served as Director of Technology for the IBM CIO, and as Director of Technology for Intelligent Infrastructure, the precursor in IBM to the current e-business on demand initiative. cells.
In his current assignment as Director of Autonomic Computing Technology, Ric is responsible for defining and delivering the architecture and technology for an emerging business area that IBM calls "Autonomic Computing." Autonomic Computing is the set of capabilities required to make a computing system more self-managing, much like the human autonomic system. Ric works across the IBM company, including servers, software and storage, to develop an end-to- end, open architecture solution for self-managing systems. Ric holds a Bachelor of Science degree in Computer Science from Trinity University in San Antonio, Texas and is a member of the Phi Beta Kappa honor society. Ric enjoys mountain biking, swimming and golf.
Abstract: In the 31months since Dr. Paul Horn, IBM Senior VP and Director of Research, introduced the concept of "Autonomic Computing", there has been tremendous acceptance and uptake across the industry. Fast Company recently named Autonomic Computing as one of the "5 technologies that will change the world." Computer Business Review listed Autonomic Computing as one of the "10 Hottest Technologies" for the decade. Software and hardware vendors alike are proclaiming their "self-management" features that represent Autonomic Computing capability. But what is behind the messages and hype of Autonomic Computing and what makes it real? Ric Telford, IBM's Director of Architecture and Technology for Autonomic Computing, gives both an overview of what IBM is doing today to drive the technology of Autonomic Computing as well as a glimpse of what is going on in IBM's Research labs for the next wave of technology. Technologies such as policy-driven infrastructure, self-healing technologies, and the Human- Computer Interaction impact of Autonomic Computing are discussed. The goal is to not only educate, but also stimulate thinking around this important emerging area of Computer Science.

Publications This is a sampling of the more than 75 exhibits of the CASCON 2003 Technology CASCON 2006 Showcase. CASCON CASCON 2005 CodeRally CASCON 2008 CodeRally is a Java programming game based on the Eclipse platform, using Eclipse and a very CASCON 2004 CASCON archives simple API to allow users who are unfamiliar with Java to learn it in a fun and easy environment - a simulated race track.

CASCON 2002 Application development CASCON 2001 Related links PRISM PRISM is research in aspect mining. The project aims at building the tool support for finding CASCON 2000 IBM University Relations code patterns representing un-modularized concerns in a very large source code base to Programming Contest support aspect oriented analysis and aspect oriented re-factoring. It is designed as a cross- CASCON 1999 Central language framework and an Eclipse plugin. IBM alphaWorks CASCON 1998 IBM developerWorks Aspect Refactorizing Verifier DB2 for Academics Aspect Refactorizing Verifier provides tool support for verifying the correctness of aspect WebSphere for Academics oriented refactorization using AJDT in Eclipse. It provides a "difference view" between the tangled logic in the pre-refactored source and the effect of aspects after refactorization. It verifies the equivalence of the places where aspect code applies as well as the logic equivalence between aspect code and the original code.
On Demand Service Level Agreement and Enforcements In this exhibit, we address new challenges faced by application service providers and service developers whilst adapting and enforcing agreements for their software services. We augment the traditional service level agreement specifications with an extended and refined definition of metrics toward efficient on-demand service level agreement. Then, we propose a generic delegation enforcement model to help the providers license, monitor, measure and reconfigure the on-demand software services based on the managed service level agreements.
Eclipse R3.0 Eclipse 3.0 is coming in the summer of 2004! It incorporates major advances from what has come before. Drop by for a preview of these advanced capabilities and technical discussions with the product architects.
Health Info Grid Solutions to integrate medical information must overcome the problems caused by many heterogeneous data sources that currently exist due to the lack of single solutions and common terminologies. In collaboration with researchers in the University of Victoria, School of Health Information Science, and practitioners in Health Care, we have developed a prototype for the Health Information Grid, a middleware technology that supports inexpensive mediation of medical information among rapidly evolving, heterogeneous medical information sources.
Soot in Eclipse Soot is an open-source framework for analyzing, optimizing, and annotating Java bytecode. Eclipse is an open-source universal tool platform. This exhibit will demonstrate the integration of Soot into Eclipse as an Eclipse plugin.
Compiler Optimization Many interesting optimization problems arise in compilers. Currently, these problems are solved heuristically in production compilers. However, techniques such as constraint programming have improved sufficiently that optimal yet fast approaches are now possible.
FEAT Developers working on existing programs repeatedly have to address concerns, or aspects, that are not well modularized in the source code comprising a system. In this exhibit we demonstrate FEAT, an Eclipse plug-in intended to help developers locate, describe, and analyze scattered concern code in Java programs.
A Call Graph Analysis Complex artificial and biological networks show graph-theoretic properties that relate to the function these networks carry. We postulate that large pieces of software represented as call graphs can also be analyzed using graph-theoretic approaches to uncover structure-function relationship relevant to software development and maintenance. We present results of our preliminary analysis of the call graphs of Postgresql versions 7.0, 7.1, 7.2, and 7.3.
Grid Configurations In the grid environment, applications make use of shared grid resources to improve performance. The target function usually depends on many parameters, e.g., the scheduling strategies, the configurations of machines and links, the workloads of a grid, the degree of data replication, etc. We examine how those parameters may affect performance.
Autonomic Licensing This exhibit presents an autonomic licensing framework for on demand services. It protects the intellectual property rights of various service vendors, and helps service users to manage multiple licenses as well.
MFLAS MFLAS is a tool for extracting useful information regarding the performance of meta- applications and their components from multiple data sources such as log files with no pre- meditated inter-connections. MFLAS allows for the generation of models such as stochastic models and analytic queuing models based upon the correlation of these information sources.
CST to AST Transformation In compilers, the grammar used for parsing is often different from the desired simpler abstract grammar that retains the essential information found in the source text file. SableCC provides a new mechanism to automatically and efficiently transform the parse tree, usually called Concrete Syntax Tree (CST), into an Abstract Syntax Tree (AST) at parse time. This approach, which is based on specifying tree transformations within the grammar, allows SableCC to apply semantic checks on these transformations.
Self Tuned OpenMP Runtime "Adjust" is a feedback guided parallel schedule that aims to provide the OpenMP runtime the capability of self-tuning himself to the behaviour of the application and the characteristics of the runtime environment.
Database
Powerful New SQL in DB2 This exhibit gives you an overview of the SQL language enhancements in DB2 UDB V8 for Linux/Unix/Windows in various aspects such as scalability, usability, and performance. The new powerful SQL language features, such as INSTEAD OF triggers, WITH ROW MOVEMENT views, INSERT through UNION ALL views, MERGE statement, SELECT FROM UPDATE / DELETE / INSERT, etc., are introduced.
DB2/UDB Capacity Planning In this presentation, we focus on DB2/UDB capacity planning for online analytical processing (OLAP) workload. A workload model is built based on TPC-H benchmark, and a queuing network model (QNM) to represent the database management system (DBMS) is proposed and validated. We also show how this QNM can represent various changes to the hardware and workloads.
Workload-Aware DBMSs In order for DBMSs to be autonomic, they must be aware of workload put upon them. This exhibit introduces a methodology by which a DBMS can predict changes in its workload. The methodology is cost-efficient and self-adapting.
Schema Mapping In dynamic environments like the Web, data sources may change not only their data but also their schemas, their semantics, and their query capabilities. Such changes may leave mappings between the data sources invalid or inconsistent and that have to be detected and updated. We present a tool (ToMAS) for automatically adapting mappings as schemas evolve. Our approach considers not only local structural changes, but also semantic changes or changes that may affect and transform many components of a schema.
Accessing DB2 UDB with .Net and J2EE We will show you how easy it is to access DB2 UDB regardless of whether you are writing a MS .Net application or a J2EE application. There are DB2 add-ins in MS Visual Studio.Net to make life easy for the .Net developer as well as integration with WebSphere Studio that makes life easy for the J2EE developer. We will also demonstrate the interoperability of .Net and J2EE Web Services.
High Availability with DB2 UDB and Steeleye LifeKeeper Through the use of IBM's DB2 UDB V8.1 and Steeleye's LifeKeeper for Linux, we are able to provide a Highly Available Database solution. When properly configured with shared resources and redundant components, this solution is able to automatically overcome any single point of failure.
SQL-Relay For each frequent user access event (i.e., the frequency of the event is higher than a predefined threshold), we predefine a set of execution rules. When a query is submitted, we find the best matched event, and execute the predefined rules associated with it.
E-Business
XML Schema Matching XML Schema matching is the foundation for XML data integration and web service matching and composition. It takes two XML Schemas as input and generates the matching pairs between the schemas. The algorithm is based on graph matching algorithms and uses both semantic and syntactic information of XML schema, with focus on XML Schema's element name, data type, cardinality, and more importantly, the hierarchical structure of XML schemas.
Interoperable Web Services Create, test, validate and monitor Interoperable Web Services with the help of WS-I compliant Web Service CheatSheet as a guide. Create WSDL files using WSDL Editor with graphic support and validate using WSDL Validator. Monitor runtime traffic using WebSphere Studio TCP/IP monitoring server and validate using WS-I Message Validator for WS-I basic Profile 1.0 compliance.
Voice for IBM Commerce This project demonstrates how IBM VoiceXML-based technology can be utilized in order to enable a voice channel support, and thus provide a true pervasive access, for IBM WebSphere Commerce Portal applications. We show the capability of the voice channel by managing customers' resources of an imaginative Winston's store.
Web Services Web services are application components callable over the internet using XML-friendly protocols. Web services are governed by, and evolving rapidly under, a variety of key standards including XML, XSD, WSDL, SOAP, UDDI, WS-Interoperability, WS-Security, JAX-RPC and JSR-109. IBM's WebSphere Studio tools and WebSphere Application Server offer rich support for developing and running interoperable Web services that comply to these, and other, standards.
Business Intelligence in WebSphere Commerce This exhibit showcases WebSphere Commerce Analyzer, an example of how Business Intelligence tools can be leveraged to give insight into WebSphere Commerce installations. The focus is on OLAP and data mining of warehoused e-business data. Solutions from CAS students are also featured.
Software engineering
J-Reflecs: Enabling the Reflective Software Development Team The J-Reflecs project aims at developing a set of plugins for supporting small teams of undergraduate student developers to reflect upon their software process and products. The poster will walk through three scenarios: (a) team members evaluating their current progress and adjusting their schedules, (b) team members querying their code design for interesting semantic information, and (c) instructors evaluating the student team progress between two versions.
ALV: As-Linked View The GNU linker ld was instrumented and used to extract as-linked views (ALVs) for large software systems. A system's ALV accurately reflects its build dependencies and symbol linkage information. The ALV extraction is transparently integrated with the build process. microSynergy The NetLab microSynergy tool coordinates microcontroller communication. The three major projects are the Editor, iFaces, and RESCUE. The Editor provides tools to modify component connections and connection logic. The iFaces project provides components with secure internet access. The RESCUE project migrates embedded legacy components to a more net-centric platform.
Verification of Business Processes for Web Services The Business Process Execution Language for Web Services (BPEL4WS) is a recently proposed XML-based language for business process specifications. A verification tool for business processes specified in BPEL4WS is presented.
Software Product Lines The Software Engineering Research Lab (SERL) at the University of Alberta has conducted studies into Software Product Lines (SPLs) for the past five years. The LINC project (Learning and Innovation in New company Creation), in collaboration with Avra Software Lab (a previous SERL spin-off), has successfully applied SPL research in the creation of a new production line for collaborative inter-organizational software that is the basis for a new spin-off company, Onware Software Corporation (www.onware.ca). Several products from a common product line that demonstrate the application of some of our SPL research results will be exhibited.
System-Family Engineering Using XML technologies System-family engineering is a software design approach based on the idea of modeling not a single system, but a family of systems. In this research we propose to express interactions and dependencies using a 'meta-grammar' captured in XML. We believe that it would be then possible to transform these rules expressed in XML into information directly reusable in the creation of the generator and of a suite of tests for the family.
Adoption-Centric Software Engineering Adoption-Centric Software Engineering (ACSE) explores approaches where software engineering tools and practices are implemented as extensions of commercial-off-the-shelf (COTS) products and middleware technologies. Developing and deploying innovative research tools as extensions to modern, commonly used platforms may ease adoption barriers as well as transition of tools and ideas from academia to industry.
TaskModeller Task modeling is the process of recording the goals, tasks, and task relationships of a project in a diagrammatic form. You can use the task modeling tool to assist you with project design activities such as task analysis, task synthesis, and object modeling. You can also use the TaskModeler to identify the conceptual objects that are required for object modeling techniques within User Engineering.
JMYSTIQ Java Charting Tool A tool developed for analysis of development and field defect data which can map to any relational database table. Several queries are built into the tool and can be further customized through a GUI interface.
Knowledge Management An integrated knowledge management system for information about WebSphere Application Server. Browsing, Search, and Web portal functions are provided within an integrated interface to a collection of meta-tagged key documents.
Lab Communities Common teams from various projects in the Toronto Lab share their experiences and best practices via collaboration and regularly scheduled meetings. The Toronto Lab's Software Engineering Process Group (SEPG) sponsors several of these communities by scheduling and facilitating meetings, recording the minutes and action items, and maintaining the repository where minutes of meetings, reference material, helpful hints and tips and other relevant documentation is stored.
Rational Suite Enterprise All of the tools in IBM Rational Suite are tightly integrated, enabling team members to understand and leverage project activities and assets throughout the lifecycle. Development assets are shared and re-used repeatedly, enhancing overall productivity and improving team collaboration.
Rational PureCoverage A line level code coverage tool for Java applications that can be used to identify areas that need additional coverage.
Business Process Modelling This exhibit shows how WebSphere Commerce uses WBI Modeler Workbench to document the business processes the product supports.
Internal Process Modelling The WBI Modeler Workbench has been used to model the WebSphere Commerce development processes at a high level showing connections between processes. The simulator has been used with actual data collected to analyze one process in detail.
Reengineering Web Systems Two tools are developed to assist the reengineering of web information systems, especially to the EJB platform. One tool is to generate Java code accessing enterprise beans that is equivalent to a SQL query. The other tool is to translate SQL queries in finder methods of EJB1.X to EJB-QL of EJB2.X. softChange softChange is a tool that assists in the recovery of the evolution of a software system using its software trails: information left behind by the contributors to the development process of the product, such as mailing lists, Web sites, version control logs, software releases, documentation, and the source code. softChange assists in the extraction of the software trails, their correlation, and further querying and visualization; it helps software developers, management and researchers in understanding how the software project has evolved from its conception.
User technologies
Applying Branding to Software User Interfaces: A Case Study Software user interfaces allow users to access the functionality provided by an application--to access valuable information and to perform mission-critical tasks. As well, marketing strategy requires that product branding be expressed in the user interface. We provide a case study of how a comprehensive branding system was applied to the user interfaces of a large set of software products. We describe the branding system, the process used to identify brandable UI elements, usability concerns, and relevant specifications and guidelines.
The Vocal Village The Vocal Village is a real-time audioconferencing application that uses VoIP to connect collaborative groups in a spatialized audio environment. The Vocal Village uses binaural cues to present the voices of individual conference participants in different locations in space. Participants are able to dynamically adjust the location of conference members as well as record and annotate the audio conference through a graphical user interface.
Eyes-Free Interaction To develop effective applications for use on mobile technology, we must embrace a paradigm shift with respect to the interaction techniques we employ for communication with such devices. Complementing the CASCON'2003 paper entitled "A Paradigm Shift: Alternative Interaction Techniques for Use with Mobile and Wearable Devices", this exhibit demonstrates two examples of 'eyes-free' interaction techniques designed specifically for use with mobile devices such that visual resource requirements are minimized. The first technique combines 3D head gestures with auditory icons; the second combines 2D hand gestures with earcons.
SHriMP Dishes Our exhibit demonstrates our work on tools to visualize, explore, and communicate information spaces. We present three applications: Jambalaya, a customizable knowledge engineering visualization toolkit; Creole, a software engineering visualization integrated into Eclipse, and an associated CVS visualization tool, Xia; SHriMP-bib, a demonstration of Jambalaya used to visualize and understand research group knowledge.
Browsing Volume Data We have developed an experimental system for browsing volumetric data. The novel aspects of this research include (i) using rigid and non-rigid deformations for browsing volumetric data, allowing the user to "peer inside" without loosing the surrounding contextual data, and (ii) sensitivity to the semantic layers (or subsets) within the data, and designing interaction techniques around these. Scalable Graphics Software interface designs that use dynamic scalable graphics can improve performance and usability, and reduce production and translation costs. You will see a demonstration of a design using scalable buttons and tabs, enriched table headers, and a dynamic table that features drag and drop, and sorting capabilities. In addition to the demo, there will be information showing how the scalable buttons are made.
Designing UML Diagrams for Technical Documentation This exhibit presents a framework for improving the presentation of UML diagrams in technical documentation. By demonstrating the specific set of guidelines, found in the UML Diagram Process Web site, developers, writers, and designers can comprehend the concept of working together to produce clean, concise UML diagrams that will add value and clarity to technical information. This clearly defined process can help eliminate miscommunication, shorten development schedules, and reduce production and translation costs.
GIF-to-EPS File Conversion Tool The G2E tool completes the workflow of creating and publishing high-quality and compact screen capture files by enabling IBM software development lab employees to produce print- ready and platform-independent versions of their captures quickly and easily. Members of the IBM Toronto Lab's Media Design Studio --working in conjunction with members of the Information Development community-- spearheaded the design and development of the G2E tool.
Designing for Customers WebSphere Commerce version 5.5 introduced a wide range of functions to support the demand chain. The parties of the demand chain, deliver products, goods, services, or information from producers to end users. A reseller is defined as a business that sells products to businesses (such as end users or other resellers), after having obtained the goods from manufacturers, distributors, or other resellers. This showcase presents two applications that allow resellers to perform their tasks with ease and efficiency. One enables the reseller to purchase products directly from their distributors online. The other provides the resellers with the ability to restrict or limit the view of the catalog to a specific set of users within a hosted store.
Video Bench The Video Bench is a video editing application with an invisible, hands-on tabletop user interface. Its support for multiple simultaneous users makes it well suited to collaborative work. Come try it out for yourself!
Gild: An Integrated Learning and Development Environment for Java Many students experience severe difficulties in introductory courses on programming. We believe technology can be developed to help students and teachers address some of the learning difficulties of technical concepts, while improving collaborative aspects between students and teachers. Gild is being designed as a set of plug-ins for Eclipse. It incorporates aspects from the Eclipse Java development tools, pedagogical tools for teaching programming, and web-based learning environments. At this technology showcase, we will present early versions of both instructor and student perspectives. Our design follows requirements we have elicited from teachers, students and teaching assistants. We welcome feedback from CASCON attendees on Gild.

IBM developerWorks DB2 for Academics Topic: Less is more (more or less) WebSphere for Academics If Rip-van-Winkle went to sleep in 1983 having used a Xerox Star or Macintosh computer, and woke up today, he would be just as able to drive today’s computers as drive today’s cars. The performance of both would have improved, but the essentials of the design would be familiar, and essentially unchanged.
In light of this conjecture, one can seriously challenge the base assumption that there has been great change and progress in computation in the intervening years. Some things have changed. But what? And are they the right things?
This presentation is largely about design, not technology (other than the most important technology of them all – the all but forgotten one – people).

Chuck Hamilton Manager e-Learning Strategy and Solutions IBM Canada Innovation Centers: Vancouver Topic: e-Learning
Charles (Chuck) Hamilton is the Manager of e-learning Strategy and Education Solutions at IBM Canada’s Innovation Center ::Vancouver and also supports the IBM world wide eLearning Strategy Team. The Centre’s Education Solutions Team was established in 1998, with one mission, - to create a world-class education technology competency Centre to serve IBM clients around the world. Today, this Centre is home for a 30-person team focused on the design, analysis, planning, and implementation of industry solutions for e-business, e-learning, classrooms management, public access, digital media and e- communities.
Chuck serves on and supports a number of e-learning organizations outside of IBM and is well known across the emerging eLearning industry. Chuck speaks at approximately ten conferences a year promoting the role of technology in education and has published several papers on elearning trends and direction. When he is not traveling around the world he spends his time at Vancouver beach volleyball nets and playing traditional Irish music in a Celtic band.
Topic: Technology Trends We Can’t Avoid In The Evolution of Learning The urgency to create an effective e-Learning strategy is compounded by the decreasing life spans of skills as the changes in technology accelerate. IBM has learned that requests from worldwide education customers often echo the lifelong learning goals of IBM employees. The resulting solution strategy is that IBM ‘eats much of its own cooking’ while continuing its world- class contribution to the educational technology industry. Still there exists no single solution, nor is there ever likely to be a single comprehensive solution meeting all educational needs, all of the time. For today’s eLearner, the slow trickle of rich media and collaboration tools merely whets the appetite for even richer content. As standards emerge to help manage rich content, education solutions become increasingly more complex, further fueling the educational technology revolution.
Chuck Hamilton, will describe IBM’s education Solution request funnel and the ‘next fourteen’ eLearning trends and technologies we need to consider for the next wave of learning delivery. Wednesday, October 2 1:30 p.m.
John Y.T. Wei, Assistant Professor, Department of Physics, University of Toronto http://www.physics.utoronto.ca/~wei/ Topic: Superconductivity
Topic: Nano Perspectives on Novel Superconductivity and Magnetism Current progress in nanotechnology is revolutionizing the study of advanced materials. In the field of novel superconductivity and magnetism, this involves the extremely short, atomic-lattice, length scales governing their basic physics, at which the quantum- mechanical nature of electrons becomes predominant and new collective phenomena begin to emerge. I will discuss some recent developments in the nanophysical study of two such quantum materials phenomena: High-Temperature Superconductivity and Colossal Magnetoresistivity. They are of great scientific intrigue, in challenging our traditional notions about electrons in solids. They also hold tremendous technological potential, in areas ranging from microelectronics to medicine, and in such nascent fields as quantum computing and spintronics. My talk will focus on possible nanoscale connections between novel superconductivity and magnetism, and their future implications for both materials physics and device applications.
Thursday, October 3 9:00 a.m.

As technology forges into the future with dramatic progress, making possible new and improved applications, we experience the creation of new paradigms daily. The scenario wherein a trader is screaming out orders amid pigeons in St. Mark's Square in Venice, while viewing a field of numbers through an eyepiece display connected to the wireless Internet, is not just a marketing videoclip; instead, it reflects the swiftest changes affecting the computing industry. A new world is dawning, one in which small and cheap appliances, yet ever more powerful, are connected to the Internet through wireless channels, realizing emerging paradigms such as locality-aware devices, always-on mobile connectivity, and environment-aware products. Smart devices, portable devices, wireless communications, and sophisticated sensors, appear to be the underlying principles of a new revolution in technology.
In this presentation, we describe BlueSpace, a project exploring the intersection of information rich technology and the design of spaces and places, taking into account physical properties and work habits of its occupants. Digital technology is used as a vehicle for sensing and affecting the physical space, exploiting diverse computing resources, and navigating complex information structures. This is accomplished through the exploitation of emerging sensor and input devices, advanced communication and display technologies, and sophisticated human-machine interaction techniques. These augmented workspaces could lead to improved personal comfort, better personalization, higher interpersonal communication and collaboration.

Joan Mitchell IBM Fellow, IBM Thomas J Watson Research
Joan L. Mitchell graduated from Stanford University with a B.S. in physics in 1969. She received her M.S. and Ph.D. degrees in physics from the University of Illinois at Champaign-Urbana in 1971 and 1974, respectively. She joined the Exploratory Printing Technologies group at the IBM T. J. Watson Research Center immediately after completing her Ph.D. She was a manager there for nine years. She then worked for three years in IBM Marketing before returning to the IBM Research Division in 1991 to work again in the Image Technologies group as a manager. From 1987 through 1994 she was a member of the ISO and CCITT international Joint Photographic Experts Group which standardized the color image JPEG compression algorithm. She was the final editor of JPEG Part 1 and in 1992 coauthored a book about JPEG. In 1994, she took a two year leave of absence from IBM. During her leave she coauthored a book on MPEG, consulted for IBM Burlington, and was a visiting professor at the University of Illinois for six months. She returned to the IBM T.J. Watson Research Center as a Research Staff Member in the Image Applications Department. Now she is on temporary assignment to the IBM Printing Systems Division in Boulder, CO. Since 1976 she has worked in the field of image processing and data compression.
She received IBM Outstanding Innovation Awards for Two-Dimensional Data Compression in 1978, for Teleconferencing in 1982, for Image View Facility in 1985, for Resistive Ribbon Thermal Transfer Printing Technology in 1985, for Speed-Optimized Software Implementations of Image Compression Algorithms in 1991, and for the Q-coder in 1991. She was elected to the IBM Academy of Technology in 1997. She was elected an IEEE Fellow in 1999 and became an IBM Fellow in 2001. She is a member of APS, IEEE, IS&T, and Sigma Xi and co-inventor on 36 patents.
The Importance of Giving Back and Reaching Back
As someone who now wants “to be the giant on whose shoulders you stand,” Joan Mitchell has come a long way. Near the start of her career at IBM, Joan recognized the need to fill a certain void in her life. For her, it was “giving back” to the community in which she worked. She began volunteering as Secretary of a local chapter of Sigma XI, an honour society dedicated to increasing the public’s understanding and appreciation of science. Taking her commitment to the next level, she became Sigma XI Vice-Chair and then Chair in the years that followed. As a result, her career at IBM was also catapulted to a gratifying level of success. Ever since the start of her volunteer career, Joan Mitchell has not only continued to “give back” to the community, but has also focused on “reaching back,” otherwise known as mentoring or networking. Through chairing conference sessions on JPEG, organizing special issues of journals, proof-reading standards and most recently, being an active participant in the Boulder Technical Vitality Council, Joan developed a firm belief that her service in the community was a key element to her success. This talk will emphasize the satisfaction and growth that resulted from taking the time to give back and reach back in her professional life.

Aristides Requicha Professor, Computer Science and Electrical Engineering Director, Laboratory for Molecular Robotics University of Southern California
Aristides A. G. Requicha is a Professor of Computer Science and Electrical Engineering at the University of Southern California, where he also directs the Laboratory for Molecular Robotics. He received the Engenheiro Electrotécnico degree from the Instituto Superior Técnico, Lisbon, Portugal, in 1962, and the Ph.D. in Electrical Engineering from the University of Rochester in 1970. He is a Fellow of the IEEE. Dr. Requicha’s past research focused on geometric modeling of 3–D solid objects and spatial reasoning for intelligent engineering systems. Currently he is working on robotic manipulation of nanometer-scale objects using scanning probe microscopes, and on its applications in nanoelectronics, NEMS (nanoelectromechanical systems), and nanobiotechnology. The long-term goals are to build, program, and deploy nanorobots for applications such as the environment or health care.
Nanorobotics
Nanorobotics is concerned with the development of robots with overall dimensions ranging from tens to hundreds of nanometers, and with the manipulation of nanoscale objects. In this talk, Ari will discuss some of the issues that arise in nanorobot construction and nanomanipulation.
Proposed designs for nanomachines and nanosensors will also be discussed. You will receive an explanation of the results obtained at USC that demonstrate how patterns of nanoparticles can be reliably constructed by pushing them on a surface with the tip of an Atomic Force Microscope (AFM). Nanoparticle patterns have many potential applications, such as high-density digital storage, single-electron transistors, and templates for growth of nanoelectromechanical systems (NEMS) and components.
Nanostructures are constructed by positioning nanoparticles with the AFM, and then by linking them chemically. This work has been performed in ambient air, in liquid, and at room temperature. In conclusion, Aristides will present results involving nanomanipulation combined with self-assembly, and their applications in building wires of arbitrary (planar) geometry and three-dimensional objects.

The Unified Modeling Language (UML) is a CASCON 2001 Related links commonly-used notation for such diagrams. We have designed and implemented a system for the on-line recognition of hand drawn UML diagrams. Input comes from a CASCON 2000 IBM University Relations drawing pad. A sophisticated segmentation algorithm groups pen strokes into symbols, Programming Contest coping with drawing inaccuracies that are common in hand drawn input. The system is CASCON 1999 Central organized around a retargetable kernel which provides a general front end for on-line CASCON 1998 IBM alphaWorks recognition of any iconic notation. The kernel is extended with UML specific IBM developerWorks enhancements to segmentation, as well as UML specific glyph recognizers. A simple DB2 for Academics and intuitive graphical user interface allows the user to correct segmentation and recognition errors. Tests show that relatively messy freehand UML drawings are WebSphere for Academics interpreted properly.
A Cognitive and User Centric Based Approach For Reverse Engineering Tool Design Iyad Zayour, University of Ottawa Timothy C. Lethbridge, University of Ottawa
Reverse engineering tools aimed at facilitating software maintenance suffer from low adoption. Many are developed, but few are used by software engineers in performing their maintenance work. We introduce an approach for tool design that is aimed at increasing the adoptability potential of tools. Our approach is based on applying cognitive analysis to identify cognitively difficult aspects of maintenance work, then deriving requirements to address these difficulties. The approach is described in the context of the implementation of a reverse engineering tool we call DynaSee, which we have used to for the visualization of traces generated by a large telecommunications system. We describe how DynaSee addresses a specific set of cognitive difficulties.
Efficient Mapping of Software System Traces to Architectural Views Robert J. Walker, University of British Columbia Gail C. Murphy, University of British Columbia Jeffrey Steinbok, University of British Columbia Martin P. Robillard, University of British Columbia
Information about a software system's execution can help a developer with many tasks, including software testing, performance tuning, and program understanding. In almost all cases, this dynamic information is reported in terms of source-level constructs, such as procedures and methods. For some software engineering tasks, source-level information is not optimal because there is a wide gap between the information presented (i.e., procedures) and the concepts of interest to the software developer (i.e., subsystems). One way to close this gap is to allow developers to investigate the execution information in terms of a higher-level, typically architectural, view. In this paper, we present a straightforward encoding technique for dynamic trace information that makes it tractable and efficient to manipulate a trace from a variety of different architecture-level viewpoints. We also describe how this encoding technique has been used to support the development of two tools: a visualization tool and a path query tool. We present this technique to enable the development of additional tools that manipulate dynamic information at a higher-level than source.
A Multi-Perspective Software Visualization Environment Jingwei Wu, University of Victoria Margaret-Anne D. Storey, University of Victoria
This paper describes a multi-perspective software visualization environment, SHriMP, which combines single-view and multi-view techniques to support software exploration at both the architectural and source code levels. SHriMP provides three views: a primary nested view and two subsidiary views. The primary nested view employs fisheye views of nested graphs, provides contextual cues, and supports general exploration activities. In SHriMP, subsidiary views exist as a searching tool and a relation tracer. These views complement each other, allowing programmers to examine a software system from multiple perspectives. Task-Directed Inspections: An Experiment and Case Study Diane Kelly, RMC Terry Shepard, RMC
Research in software inspection has led to the development of inspection techniques focused on providing structure and guidance to the individual inspector, with the goal of improving effectiveness. This paper defines and investigates a new inspection technique, task-directed inspection, specifically developed for inspecting complex computational code, but capable of being applied in other software domains. Students from the Royal Military College of Canada and Queen's University in Kingston, as participants in an experiment, applied two task directed techniques and an industry- standard nonstructured inspection technique to a civil engineering code in use in military applications. Results from the experiment were analyzed with a new Orthogonal Defect Classification for computational code developed for this research. Based on this small sample group, the task-directed techniques show promise in helping software inspectors more thoroughly examine and understand software code. This research also clearly points out the differences between experienced and inexperienced inspectors, and opens up several possibilities for further research.
Supporting Maintenance of Legacy Software with Data Mining Techniques Jelber Sayyad Shirabad, University of Ottawa Timothy C. Lethbridge, University of Ottawa Stan Matwin, University of Ottawa
Software maintenance is a very costly and time consuming part of the software life cycle. The problems with software maintenance are even more pressing in the case of legacy software systems. This paper describes our research towards application of inductive methods to the data extracted from source code, software maintenance records, and software developers activities to learn a Maintenance Relevance Relation among files in a software system. We discuss the methodology employed, and some of the encountered problems and our solutions for them. The paper will also present some of the results that we have obtained.
Simulating DB2 Buffer Pool Management Wenguang Wang, University of Saskatchewan Richard B. Bunt, University of Saskatchewan
Storage management is an important part of any DBMS. The buffer pool in DB2 is used to cache the disk pages of the database, and its management algorithm can significantly affect performance. In order to investigate performance issues relating to the buffer pool management algorithm, a trace of buffer pool requests was collected and a trace-driven simulator was developed so that the impact of various parameters of the buffer pool management algorithm could be investigated under controlled circumstances. Relationships among different activities competing for storage space and the I/O channel are examined, and some issues affecting the performance are identified.
Queueing model based QoS management prototype for e-commerce systems Timofei Popkov, St. Petersburg State Technical University Sergei Oskotskij, St. Petersburg State Technical University
The user can specify his or her requirements to the system by means of priority and higher priority users will be guaranteed with higher QoS, which, however, may not be free. The main part of the proposed management system is a queueing mode, which is presented and analyzed as well. Presented e-commerce management system prototype implements the core management functionality and can serve as a basis for building real-life QoS management system for such products as IBM Net.Commerce system and IBM WebSphere commerce suit.
Performance Modeling of Nested Transactions in Database Systems Hossam Hassanein, Queen's University Mohamed El-Sharkawi, Cairo University
The nested transaction model was introduced to satisfy the requirements of advanced database applications. Moreover, it is currently the basic transaction model for new databases like workflow systems, mobile databases, and object-relational databases. Though there are several performance evaluation studies of different concurrency control mechanisms in nested transactions, effects of transaction parameters on the overall system performance have not received any attention. In this paper, we study the effects of transactions characteristics on system performance. We developed a detailed simulation model and conducted several experiments to measure the impact of transactions characteristics on the performance. First, the effect of the number of leaves on the performance of nested transactions is investigated under different shaping parameters. Also, effects of the depth of the transaction tree on the system performance are investigated.
Model Checking the Composition of Hypermedia Design Components Jing Dong, University of Waterloo
Component-based software development becomes increasingly popular because it can reduce development expense, but the conflict among software components is often one of the important barriers to the success of their composition. The analysis of the properties of the components and their compositions allows us to detect and correct composition errors. Discovering problems early rather than late in the development process can save considerable effort of fixing errors downstream. In this paper, we demonstrate how model checking can be used to verify properties for software design composition. With a case study, we show the representation, instantiation, integration of design components, and find design composition errors by a model checker. Our design analysis process can be seen as a lightweight approach to the application of formal methods.
Bisimulation Analysis of SDL-Expressed Protocols: A Case Study Marsha Chechik, University of Toronto Hai Wang, University of Toronto
This paper presents a family of new protocols, termed Asynchronous Retransmission Go-Back-$N$ (AR), which are improvements on the Go-Back-$N$ protocol in environments characterized by high error rates and/or large propagation delays. In order to verify that the use of these protocols, expressed in SDL, is transparent to the user, we explore the feasibility of their bisimulation checking. We discuss the main issues involved in translating SDL into Concurrency Workbench, a tool for performing bisimulation checking, and apply the results to verifying correctness of AR protocols.
A Framework Algorithm for Dynamic, Centralized Dimension-Bounded Timestamps Paul A.S. Ward, Shoshin Distributed Systems Group
Vector timestamps can be used to characterize causality in a distributed computation. This is essential in an observation context where we wish to reason about the partial order of execution. Unfortunately, all current dynamic vector-timestamp algorithms require a vector of size equal to the number of processes in the computation. This fundamentally limits the scalability of such observation systems. In this paper we present a framework algorithm for dynamic vector timestamps whose size can be as small as the dimension of the partial-order of execution. While the dimension can be as large as the number of processes, in general it is much smaller.
The algorithm consists of three interleaved phases: computing the critical pairs, creating extensions that reverse those critical pairs, and assigning vectors to each event based on the extensions created. We present complete solutions for the first two phases and a partial solution for the third phase.
A Framework for Optimizing Java Using Attributes Patrice Pominville Feng Qian Raja Vallee-Rai Laurie Hendren Clark Verbrugge
This paper presents a framework for supporting the optimization of Java programs using attributes in Java class files. We show how class file attributes may be used to convey both optimization opportunities and profile information to a variety of Java Virtual machines including ahead-of-time compilers and just-in-time compilers. We present our work in the context of Soot, a framework that supports the analysis and transformation of Java bytecode (class files). We demonstrate the framework with attributes for elimination of array bounds and null pointer checks, and we provide experimental results for the Kaffe JIT, and IBM's High Performance Compiler for Java ahead-of-time compiler.
Automatic Detection of Immutable Fields in Java Sara Porat, IBM Research Lab., Haifa, Israel Marina Biberstein, IBM Research Lab., Haifa, Israel Larry Koved, IBM T. J. Watson, USA Bilha Mendelson, IBM Research Lab., Haifa, Israel
This paper introduces techniques to detect mutability of fields and classes in Java. A variable is considered to be mutable if a new value is stored into it, as well as if any of its reachable variables is mutable. We present a static flow-sensitive analysis algorithm which can be applied to any Java component. The analysis classifies fields and classes as either mutable or immutable. In order to facilitate open-world analysis, the algorithm identifies situations that expose variables to potential modification by code outside the component, as well as situations where variables are modified by the analyzed code. We also present an implementation of the analysis which focuses on detecting mutability of class variables, so as to avoid isolation problems. The implementation incorporates intra- and inter-procedural data-flow analyses and is shown to be highly scalable. Experimental results demonstrate the effectiveness of the algorithms.
Multinational Online Stores in a Single Commerce Server Yumman Chan Hendra Suwanda
With the onset of the Internet, traditional constraints such as geographical barriers have been abolished. Companies are no longer prevented from doing business simply because they are located in different parts of the world. However, there still remain barriers such as taxation, shipping, business practices, language and cultural differences that still prohibit a true globalized marketplace. To best serve customers, it is becoming increasingly important that companies address the wide range of business, languages and cultures when doing business through the Internet.
It is significantly less expensive to develop, maintain (catalogues and systems) and operate a single web sites that span across multiple languages and countries than dedicating a server for each country. It is very often a top business priority to architect these multi-cutlure sites such that the cost of doing e-business in multiple countries is kept to the absolute minimum.
This paper describes various business and technical challenges, as well as a proven architecture that satisfies the desire to do e-business across multiple countries in an efficient and profitable way.
WitanWeb and the Software Engineering of Web-based Applications J Howard Johnson, Institute for Information Technology, NRC Stephen A. MacKay, Institute for Information Technology, NRC
WitanWeb is a web-based application which supports the interactions among program committee, authors, and reviewers for the refereeing process of conferences. Since development on it began in 1997, it has evolved a great deal to support the requirements of CASCON, WWW8, and ICSE 2001 as well as several other significant conferences. The development focus has emphasized usability related to the task as well as security, integrity, and availability to encourage the development of trust by each class of users.
The architecture and development process of WitanWeb is discussed as well as the experience gained about particular issues of software evolution as it relates to web- based systems. New insights on software engineering are provided by software engineering researchers forced to meet tight deadlines without compromising the above goals or losing data through software or hardware failure.
Migration and Web-Based Integration of Legacy Services Ying Zou, University of Waterloo Kostas Kontogiannis, Unversity of Waterloo
With the explosive growth of the Internet, businesses of all sizes aim on applying network-wide solutions to their IT infrastructures, migrating their legacy business processes into web-based environments, and establishing their own on-line services. To facilitate process and service integration, a complete and information rich service description language, is essential for server processes to be specified and for client processes to be able to locate services that are available in Web-enabled remote servers. Within the context of emerging technologies, such as XML, Internet, and Web- enabled application servers, we propose an architecture that allows for the migration of legacy services to distributed environments. The architecture is based on legacy component wrapping, a service description language that allows for the specification of services at higher levels of abstraction than the standard Interface Description Languages (IDLs), and on techniques that support service registration and dynamic service localization.

Chris Bahr Program Director, developerWorks and alphaWorks
John Wolpert Manager, alphaWorks
IBM alphaWorks began its life in 1996 in Armonk, NY, spearheaded by John Patrick (IBM Vice President, Internet Division). Patrick's vision was to create a Web site that surfaced IBM's hottest Internet technologies from research, and established a cutting-edge Web presence for IBM.
In March 1998, alphaWorks refocused its efforts on speeding emerging IBM technology to market. The Web site is a focal point for providing early adopter developers access to strategic emerging technologies from IBM's top researchers and developers. The feedback generated by alphaWorks users is incorporated back into the technologies. This not only reduces development time, and speeds technologies to market, but allows IBM to gauge the interest, success or validity of IBM's earliest software innovations.
The alphaWorks team works internally to build a business case around each technology, called an "alphaBrief", and uses feedback and statistics to determine the next step for a technology. alphaWorks has been successful in helping IBM establish leadership in new standards and transferring technologies surfaced on our site to IBM products, open-source licenses and OEM license opportunities.

Forward and Reverse Repair of Software Architecture John B. Tran, University of Waterloo Richard C. Holt, University of Waterloo
As a software system evolves, it is common for the as-built architecture to diverge from the as-designed architecture. This gap between the as-designed (conceptual) and the as-built (concrete) architecture leads to a false understanding of the system, resulting in error prone maintenance decisions. We present an approach to repair an architecture of a software system. Our approach attempts to reconcile the conceptual architecture with the concrete architecture by performing a series of simple, semi- automatic repair actions. We applied our architecture repair actions to the Linux kernel and were able to repair many of the anomalies its architecture.
Multiple-Granularity Interleaving for Piggyback Query Processing Brian Dunkel, The University of Michigan, Ann Arbor Qiang Zhu, The University of Michigan, Dearborn Wing Lau, The University of Michigan, Dearborn Suyun Chen, IBM Toronto Laboratory
Piggyback query processing is a new technique, described in our previous work, that seeks to perform additional useful computation (such as collecting or validating data statistics) during normal query processing, taking full advantage of any data resident in main memory. Although different types of beneficial piggybacking have been identified and studied, the effective and efficient integration of piggyback operations with a given user query is still an open issue. In this paper, we propose a method of multiple- granularity interleaving that allows the efficient integration of multiple piggyback operations with a given query at different levels of data granularity. We introduce an algebraic notation that captures the main characteristics of query processing in a database management system (DBMS), which not only facilitates the study of piggybacking techniques but also enables the automated integration of piggyback operations and user queries in a DBMS implementing the piggyback method. Various techniques for this integration are suggested to facilitate multiple-granularity interleaving of piggyback operations and user queries including merging, connecting, augmenting user queries, and downgrading piggyback operations. A set of transformation rules and heuristics are presented that preserve the sematics of a user query, while improving the efficiency of interleaved operations. Our preliminary experiments indicate that interleaving at proper levels of data granularity is key to the efficient implementation of the piggyback method.
Storage Estimation for Multidimensional Aggregates in OLAP Kanda Runapongsa, The University of Michigan, Ann Arbor Thomas P. Nadeau, The University of Michigan, Ann Arbor Toby J. Teorey, The University of Michigan, Ann Arbor
On-line analytical processing (OLAP) is an important technique for analyzing data in decision support systems. Most analytical queries require aggregation of the interesting data. Pre-aggregation is one of the most important techniques used to speed up the query response time. However, precomputing every aggregate takes a large amount of time and space. The decision of which aggregates should be precomputed and how much space is required is thus important. By estimating the storage space required for each aggregate view, we can allocate the space for aggregates efficiently and decide which aggregates to precompute. We investigate four existing strategies for this problem: two based on mathematical approximations, one based on sampling, and one hybrid approach based on mathematical approximation and sampling. We propose a new hybrid strategy that is based on mathematical approximation and sampling and is easy to compute. We evaluate the accuracy of these algorithms in estimating the storage explosion due to aggregation for different data distributions and data densities. The results indicate that our proposed strategy approximates the explosion more accurately than other strategies.
Software Architecture Abstraction and Aggregation as Algebraic Manipulations
Richard C. Holt, University of Waterloo
The structure of a large system can be made comprehensible if it can be viewed as a modest number of interacting entities. For example, the 800,000 line Linux kernel can be reasonably viewed as its five top-level interconnected subsystems. Each abstracted entity (subsystem) may have aggregated attributes, e.g., the total count of the number of lines of code in it, or the set of programmers who have worked on it. Given that the software architecture of the system is represented as a typed graph, both abstraction (ignoring details inside subsystems) and aggregation (collecting selected internal information) can be specified as algebraic manipulations. Our approach, based on Tarski relational algebra, allows direct execution of these abstraction and aggregation specifications by means of a relational calculator.
Migration of Procedural Systems to Network Centric Platforms Prashant Patil, Univerisity Of Waterloo Ying Zou, University of Waterloo Kostas Kontogiannis, University of Waterloo John Mylopoulos, University of Toronto
Technologies developed over the past few years such as CORBA, Java and the Web, have made it easier to build and deploy distributed object applications. These technologies have also made a visible impact on legacy software system evolution.
This paper focuses on the methods for re-engineering of procedural systems into new Network-Centric platforms. The first step of this re-engineering method is to migrate a legacy system into an object oriented architecture. The extraction of objects is based on global data type analysis and an evidence model that allows for alternative target designs to be evaluated and ranked. Once a target design has been extracted, C++ code is generated for the re-engineered system. The second step is to wrap the components of the new system with interfaces, so that they can be made available through a network centric workbench such as CORBA.
Automatically generated IDL interfaces, and CORBA compliant wrapper classes allow for the migration of the new code to a distributed Network-Centric environment. A prototype tool has been built and in this paper we discuss how these re-engineering techniques are applied to three medium size C systems.
Leveraging IBM VisualAge for C++ for Reverse Engineering Tasks Johannes Martin, University of Victoria
The IBM VisualAge for C++ development environment provides tool writers with the ability to query the compiler's internal data structures for information on the programs being compiled. This paper shows how these features can be used to supply data to common reverse engineering tools, and what the advantages over traditional approaches to writing parsers for reverse engineering tools are.
A Model Independent Source Code Repository Anthony Cox, University of Waterloo Charles Clarke, University of Waterloo Susan Sim, University of Toronto
Software repositories, used to support program development and maintenance, invariably require an abstract model of the source code. This requirement restricts the repository user to the analyses and queries supported by the data model of the repository. In this work, we present a software repository system based on an existing information retrieval system for structured text. Source code is treated as structured text, augmented with supplementary syntactic and semantic information. Both the source text and the supplementary information can then be queried to retrieve elements of the code. No transformations are necessary to satisfy the requirements of a database storage model. As a result, the system is free of many of the limitations imposed by existing systems.
Towards Array Bound Check Elimination in Java (TM) Virtual Machine Language Hongwei Xi, Oregon Graduate Institute Songtao Xia, Oregon Graduate Institute
The Java Virtual Machine Language (JVML) is a platform independent programming language at bytecode level. A Java program is compiled into JVML bytecode in the standard Java implementation, which may be transferred across networks to and then interpreted by the Java Virtual Machine. For safety concerns, JVML disallows out-of- bounds array access. In practice, this is enforced through run-time array bounds checking. Unfortunately, this practice can be prohibitively expensive in cases involving numerical computation such as animation.
In this paper, we propose a type-theoretic approach to eliminating run-time array bound checks in JVML and demonstrate that the property of safe array access can be readily captured with a restricted form of dependent type system and therefore enforced through type-checking. We focus on a language JVMLa, which is basically a subset of JVML with array access instructions, and prove that the execution of a well- typed JVMLa program can never cause memory violations.
Soot - a Java Bytecode Optimization Framework Raja Vallée-Rai, McGill University Phong Co, McGill University Etienne Gagnon, McGill University Laurie Hendren, McGill University Patrick Lam, McGill University Vijay Sundaresan, McGill University
This paper presents Soot, a framework for optimizing Java bytecode. The framework is implemented in Java and supports three intermediate representations for representing Java bytecode: Baf, a streamlined representation of bytecode which is simple to manipulate; Jimple, a typed 3-address intermediate representation suitable for optimization; and Grimp, an aggregated version of Jimple suitable for decompilation. We describe the motivation for each representation, and the salient points in translating from one representation to another.
In order to demonstrate the usefulness of the framework, we have implemented intraprocedural and whole program optimizations. To show that whole program bytecode optimization can give performance improvements, we provide experimental results for 12 large benchmarks, including 8 SPECjvm98 benchmarks running on JDK 1.2 for GNU/Linux. These results show up to 8% improvement when the optimized bytecode is run using the interpreter and up to 21% when run using the JIT compiler.

The Specification of Distributed Objects: Liveness and Locality Paolo A.G. Sivilotti, The Ohio State University Charles P. Giles, The Ohio State University
There are two aspects to the behavioral specification of an object in a distributed system: safety and liveness. This paper describes our component-based mechanism for specifying liveness. The specification of a distributed object is typically a syntactic definition of its interface (\eg, the method signatures). Several proposals have been made to extend these syntactic definitions to provide behavioral information (\eg, preconditions and postconditions). However, many of these proposals have failed to address liveness properties. In this paper, we argue for the need to express such properties. Our approach is a simple extension of CORBA IDL. Our extension is guided by the ``design-by-contract'' philosophy of sequential systems. In particular, our approach is consistent with testing for contract violations and debugging. These activities are critical for the practical use of any specification methodology in real systems.
Increasing the Flexibility of Modelling Tools via Constraint-Based Specification
Philip Gray, University of Glasgow Ray Welland, University of Glasgow
Most commercial modelling tools provide support for customising surface features of a model. Although useful and simple to use, such customisation is typically very limited; for example, one cannot change the basic representation of model components. Meta- CASE tools offer the potential for much greater customisation, but at a high cost, viz., the tool must be respecified and rebuilt. We propose an approach, constraint-based specification, which combines the flexibility of current tools with the power of CASE tool builders.
A Static Measure of a Subset of Intra-procedural Data Flow Testing Coverage Based on Node Coverage E. Merlo, École Polytechnique of Montréal G. Antoniol, IRST-Istituto per la Ricerca Scientifica e Tecnologica
In the past years, a number of research works, which have been mostly based on pre and post dominator analysis, have been presented about finding subsets of nodes and edges (called ``unrestricted subsets'') such that their traversal during execution (if feasible) exercises respectively all feasible nodes and edges in a Control Flow Graph (CFG). This paper presents an approach to statically measure the intra-procedural data flow (def-use) coverage obtained by exercising an ``unrestricted subset'' of nodes during testing. This measure indicates the possible degree of data flow testing obtainable while using a weaker test coverage criteria. The approach has been implemented in C++ on a PC under Linux and results obtained from the analysis of ``Gnu find tool'', which is about 16 KLOC of C-language source code, are presented together with discussions and conclusions.

Nick Shelness Chief Technology Officer, Lotus Development Corporation
In this talk, Nick will look at current computer hardware, communications, and market trends. Rather than attempt to predict the future, which is a mug's game, he will examine the possible implications if these trends continue. For example, if technology continues to advance as it has, by 2008, laptop computers will operate at 3-5 gigahertz, have 3-5 gigabytes of RAM, and 80- 160 gigabytes of disk storage. Whether these are under- or overestimates, no one can answer. Regardless, a whole set of questions can be asked. How might this extra power and RAM be used? How can 80-160 gigabytes of data be organized? Nick will address such questions in his talk.
Gary Saarenvirta Principal, Loyalty Consulting Data mining
Gary will present an overview of the data mining process, followed by a discussion of the business benefits of data mining and how these benefits provide a cost justification for implementing data warehousing. Gary will also review data mining algorithms, including neural networks, decision trees, association rules, clustering methods and genetic algorithms, and how they can be used in business. Finally, two case studies in clustering and predictive modelling will be examined, comparing statistical methods with machine learning and artificial intelligence ones.
Mark Bregman IBM VP, Pervasive Computing Pervasive Computing
Pervasive Computing isn't a buzz word. It's not something that is going to happen in the future. Pervasive computing has arrived. It's the natural extension of the networked world we live in, and the e-business era we are just beginning. Like e-business, Pervasive Computing will make work and life easier, and more fun. Pervasive Computing is about conveniently accessing relevant information and easily acting on it -- immediately -- through a new generation of intelligent devices such as personal digital assistants (PDAs), kiosks, or screen phones. It places the power of computing in our hands, literally. In his presentation, Mark will discuss why we should care about Pervasive Computing right now, when its effects will be felt on the marketplace, and how IBM is planning for Pervasive Computing.
Bruce Damer President and CEO, Digital Space Corporation CyberSpace Becomes a Place
Cyberspace is about to become a real place. The PC has evolved into a capable real-time 3D platform and is now serving as a portal into large scale Internet hosted 2D and 3D virtual worlds inhabited by thousands of users represented as avatars. The rise of these true virtual spaces in Cyberspace moves us beyond the document metaphor of the Web, and the point-to- point broadcast model of email and videoconferencing. In these spaces, visitors experience a sense of place, create shared memory, leave persistent objects, and experiment with new forms of identity. These first virtual worlds may be a glimpse at the ultimate shape of Cyberspace. Despite their early state of development, they suggest the coming of a powerful new medium for collaboration, play and learning in the 21st century. Bruce will discuss the applications and economics of the technology, the system and user interface architectural issues of constructing these spaces and the social craft of creating and sustaining the communities within them. Then, he will take us on a grand tour of some worlds existing in digital space.
