Integration of CUDA Processing Within the C++ Library for Parallelism and Concurrency (HPX)
1 Integration of CUDA Processing within the C++ library for parallelism and concurrency (HPX) Patrick Diehl, Madhavan Seshadri, Thomas Heller, Hartmut Kaiser Abstract—Experience shows that on today’s high performance systems the utilization of different acceleration cards in conjunction with a high utilization of all other parts of the system is difficult. Future architectures, like exascale clusters, are expected to aggravate this issue as the number of cores are expected to increase and memory hierarchies are expected to become deeper. One big aspect for distributed applications is to guarantee high utilization of all available resources, including local or remote acceleration cards on a cluster while fully using all the available CPU resources and the integration of the GPU work into the overall programming model. For the integration of CUDA code we extended HPX, a general purpose C++ run time system for parallel and distributed applications of any scale, and enabled asynchronous data transfers from and to the GPU device and the asynchronous invocation of CUDA kernels on this data. Both operations are well integrated into the general programming model of HPX which allows to seamlessly overlap any GPU operation with work on the main cores. Any user defined CUDA kernel can be launched on any (local or remote) GPU device available to the distributed application. We present asynchronous implementations for the data transfers and kernel launches for CUDA code as part of a HPX asynchronous execution graph. Using this approach we can combine all remotely and locally available acceleration cards on a cluster to utilize its full performance capabilities. -

The majority of current runtime systems focus a great deal of effort on optimizing the inter-node parallelism by MATRIX is a many-task computing job scheduling system maximizing the bandwidth and minimizing the latency of the use [3]. There are many resource managing systems aimed towards of interconnection networks and storage, but suffer from the lack data-intensive applications. Furthermore, distributed task of scalable solutions to expose the intra-node parallelism. Many- scheduling in many-task computing is a problem that has been task computing (MTC) is a distributed fine-grained paradigm that considered by many research teams. In particular, Charm++ [4], aims to address the challenges of managing parallelism and Legion [5], Swift [6], [10], Spark [1][2], HPX [12], STAPL [13] locality of exascale systems.

A Complete Survey on Software Architectural Styles and Patterns
Available online at www.sciencedirect.com ScienceDirect Procedia Computer Science 70 ( 2015 ) 16 – 28 4th International Conference on Eco-friendly Computing and Communication Systems, ICECCS 2015 A Complete Survey on Software Architectural Styles and Patterns Anubha Sharmaa*,Manoj Kumarb, Sonali Agarwalc a,b,cIndian Institute of Information Technology,Allahabad 211012,India Abstract Software bought revolutionary change making entrepreneurs fortunate enough to make money in less time with least effort and correct output. SDLC (Software development life cycle) is responsible for software’s reliability, performance, scalability, functionality and maintainability. Although all phases of SDLC have their own importance but Software architecture serves as the foundation for other phases of SDLC. Just like sketch of a building helps constructor to correctly construct the building, software architecture helps software developer to develop the software properly. There are various styles available for software architecture. In this paper, clear picture of all important software architecture styles are presented along with recent advancement in software architecture and design phases. It could be helpful for a software developer to select an appropriate style according to his/her project’s requirement. An architectural style must be chosen correctly to get its all benefits in the system. All the architectural styles are compared on the basis of various quality attributes. This paper also specifies the application area, advantages and disadvantages of each architectural style. © 20152015 The The Authors. Authors. Published Published by byElsevier Elsevier B.V. B.V.

Innovative Feedback System Based on Ibm Bluemix Cloud Service
INNOVATIVE FEEDBACK SYSTEM BASED ON IBM BLUEMIX CLOUD SERVICE P.P.N.G. Phani Kumar1, N. Anil Chakravarthy2, D.V.S.Ravi Varma3, M.Y.V.Nagesh4 1,2,3,4 Assistant Professor, Department of CSE, Raghu Engineering College, Visakhapatnam, (India). ABSTRACT Getting the right feedback at right time is most important for any organization or an institution. Getting the feedback from the users will help an organization or institution to provide better services to the users or students. Ongoing interaction with users can improve the efficiency of an organization and enable them to provide better service to the users. Until now, several feedback systems are in use which are mostly manual. We propose an efficient feedback system using cloud based computing to generate the report of the faculty performance. In the proposed system all the activities will be done by the use of cloud application Platform as a Service, through the use of IBM Bluemix. Keywords: Android, Bluemix, Cloud Computing, Paas (Platform As A Services) I INTRODUCTION Cloud Computing[1] is a popular technology in which internet and central remote servers are used to store and maintain the data, applications. Cloud computing allows people to use applications without installation of any specialized software and access the required computing facilities from anywhere via internet. By using Cloud computing we can achieve much more efficient computing power by centralizing data storage, processing and bandwidth. Cloud can be available as various services Software as a service (SaaS), Platform as a service (PaaS), Infrastructure as a service (IaaS) 1.1 Services Fig.1: Cloud Computing Services 260 | P a g e Software as a service (SaaS): Software as a service is one type of cloud service in which an application software is installed and manage in the cloud. -

Master’s degree project Source code quality in connection to self-admitted technical debt Author: Alina Hrynko Supervisor: Morgan Ericsson Semester: VT20 Subject: Computer Science Abstract The importance of software code quality is increasing rapidly. With more code being written every day, its maintenance and support are becoming harder and more expensive. New automatic code review tools are developed to reach quality goals. One of these tools is SonarQube. However, people keep their leading role in the development process. Sometimes they sacrifice quality in order to speed up the development. This is called Technical Debt. In some particular cases, this process can be admitted by the developer. This is called Self-Admitted Technical Debt (SATD). Code quality can also be measured by such static code analysis tools as SonarQube. On this occasion, different issues can be detected. The purpose of this study is to find a connection between code quality issues, found by SonarQube and those marked as SATD. The research questions include: 1) Is there a connection between the size of the project and the SATD percentage? 2) Which types of issues are the most widespread in the code, marked by SATD? 3) Did the introduction of SATD influence the bug fixing time? As a result of research, a certain percentage of SATD was found. It is between 0%–20.83%. No connection between the size of the project and the percentage of SATD was found. There are certain issues that seem to relate to the SATD, such as “Duplicated code”, “Unused method parameters should be removed”, “Cognitive Complexity of methods should not be too high”, etc. -
