Pattern/Operator Based Problem Solving Environments Cecilia Gomes1,OmerF.Rana2, and Jose C. Cunha1 1 CITI Center, University Nova de Lisboa, Portugal 2 School of Computer Science, Cardiff University, UK Abstract. Problem Solving Environments (PSEs) provide a collection of tools for composition of scientific applications. Such environments are often based on graphical interfaces that enable components to be combined, and in some cases, subsequently scheduled on computational resources. A novel approach for extending such environments with De- sign Patterns and Operators is described – as a way to better manipu- late the available components – and subsequently manage their execu- tion. Users make use of these additional abstractions by first deploying ‘Structural Patterns’ and by refining these through ‘Structural Opera- tors’. ‘Behavioural Patterns’ may then be used to define the control and data flows between components – subsequent use of ‘Behavioural Oper- ators’ manage the final configuration for execution control and dynamic reconfiguration purposes. We demonstrate the implementation of these Patterns and Operators using Triana [14] and the Distributed Resource Management Application (DRMAA) API [10]. 1 Introduction and Motivation A Problem Solving Environment (PSE) is a complete, integrated computing environment for composing, compiling, and running applications in a specific area [1]. In many ways a PSE is seen as a mechanism to integrate different software construction and management tools, and application specific libraries, within a particular problem domain. One can therefore have a PSE for finan- cial markets [4], for Gas Turbine engines [5], etc. Focus on implementing PSEs is based on the observation that previously scientists using computational methods wrote and managed all of their own computer programs – however now compu- tational scientists must use libraries and packages from a variety of sources, and those packages might be written in many different programming languages.

Abstract This document describes experiences in the implementation of the Distributed Resource Management Application API (DRMAA) specification for the PBS/Torque workload management system and Open DRMAA Service Provider (OpenDSP v1.0). The document reports about issues that where identified during implementation and test of a DRMAA C library for PBS/Torque, which was evaluated successfully with the DRMAA working group compliance test for C bindings. We will also give suggestions for improvement of the specification, mainly concerning readability of the GFD-R-P.022 document.

Dayton St., Madison, WI 53706-1685, U.S.A. 3 Dept. of Earth Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EQ, United Kingdom Abstract The grid community has been migrating towards service-oriented architectures as a means of exposing and interacting with computational resources across organizational boundaries. The adoption of Web Service standards provides us with an increased level of manageability, extensibility and interoperability between loosely coupled services that is crucial to the development of a grid infrastructure spanning multiple organizations and incorporating a wide range of different services. Providing support for Web Services in existing middleware and tools would ensure open interoperability with future mainstream grid developments. We cover in this paper the work that we have done in incorporating Web Service support into Condor – a widely adopted and sophisticated high-throughput computing software package, and present an overview of the motivations, implementation and achievements of this work. In order to demonstrate Condor’s new capabilities, we also present work that we have done in adapting GridSAM, a Web- Service based job submission and monitoring system that endorses the emerging Job Submission Description Language (JSDL) standard, in order for it to interact with Condor through its Web Service API – as well as demonstrate the use of this combination of services to deploy real-world scientific workflows in the context of the e-Minerals project.

Oracle Grid Engine: an Overview
An Oracle White Paper August 2010 Oracle Grid Engine: An Overview Oracle White Paper—Oracle Grid Engine: An Overview Executive Overview Oracle Grid Engine is a powerful workload management tool for maximizing the business value of an organizations computing resources. By using Oracle Grid Engine, businesses can deliver their products faster, more efficiently, and with lower overall costs. This paper Introduces the Oracle Grid Engine product and some common and uncommon use cases. 1 Oracle White Paper—Oracle Grid Engine: An Overview Introduction to Workload Management A computer is a great tool for doing work. For a desktop user that work looks like editing spreadsheets, visiting web sites, and playing Tetris when no one else is looking. The job of the computer is mostly just moving letters and numbers and windows around on the screen. For a server, however, the work looks very different. A server spends its days doing things like hosting web sites, processing email messages, and running calculations. Web sites and email are known as services. They're only useful if they're always (or almost always) there. If they move around or aren't always available, no one will use them. Services are most often run on dedicated machines. Servers tend to be used for one of two purposes: running services or processing workloads. Services tend to be long-running and don't tend to move around much. Workloads, however, such as running calculations, are usually done in a more "on demand" fashion. When a user needs something, he tells the server, and the server does it.
