The performance of a distributed system depends upon the efficiency of job distribution among processing nodes, as well as that of its system architecture and operating system. This paper presents an extended C language, ParaC, that supports efficient parallel programming on distributed systems. ParaC is designed to reduce the effort of job distribution on distributed programming environments. Our design includes the description of design goals for the parallel language, the definition of a programming model and the design of ParaC constructs. This paper also addresses the detailed design issues related to translation and finally presents our prototype.

OMG's (Object Management Group) CORBA (Common Object Request Broker Architecture) is becoming a common platform for distributed computing environment. However, it is yet to address CSCW (Computer Supported Collaborative Work) ftamework. This paper addresses the problem of building a framework for CSCW and proposes a new CSCW framework based on CORBA (CFC). CFC includes session, participant, mode, directory, stream, media and resource management. A desktop conference system and DSM-CC compliant video-on-demand system were built to demonstrate the usefulness of the framework. The performance of CORBA based CSCW applications is given. The strengths and weaknesses of using a CORBA framework are also discussed. © 1997 IEEE.

International Conference on parallel and Distributed Systems (ICPADS)

This paper demonstrates how the demultiplexor is used for making a new tree embedded in a MIN and how the Augmented Generalized Cube Network is designed using this tree. Evaluation of its performance and examination of its characteristics are also included. The demultiplexor was originally used for providing tolerance for destination link failures. The above shows that the AGCN gets better performance than other MINs. Not only does the AGCN have all of the Generalized Cube Network's features but it also offers multiple paths using a new embedded tree and intrastage links. Its self-adaptive routing in the last stage can alleviate tree saturation and contribute greatly to performance improvement.

International Conference on High Performance Computing in the Asia-Pacific Region

As a parallel system employs more processors to become more complex, it is very hard to understand, evaluate, and tune the system without the aid of the performance information visualization. Many researchers have found that the criteria of good visualization usually include scalability, multiple views, context and user interaction. In spite of much research in performance visualization of a parallel system, only a few results are available which meet those criteria in an integrated fashion. The paper presents an integrated visualization framework satisfying those criteria for interprocessor communication using 3-D virtual space. The proposed framework is currently applied to a parallel system SPAX (Scalable parallel Architecture computer based on Xcent-net) being developed by the ETRI (Electronics and Telecommunications Research Institute).

BULK-SYNCHRONOUS parallel ALGORITHMS FOR QR AND QZ MATRIX FACTORISATION

引用

parallel Algorithms and Applications. 1997年第1-2期11卷 97-112页

作者： RADU CALINESCU DAVID J. EVANS [a] Programming Research Group Oxford University Computing Laboratory Oxford 0X1 3QD UK [b] Parallel Algorithms Research Centre Loughborough University of Technology Loughborough Leicestershire LE11 3TU UK

This paper presents bulk-synchronous parallel (BSP) algorithms for linear system solving through QR and QZ factorisation. The two new algorithms are analysed in terms of the BSP cost model, and portable implementations of the QR and QZ decomposition methods are devised using the Oxford BSP Library. The experimental results obtained on a shared-memory multiprocessor accurately match the theoretical predictions, permitting a thorough comparison of the two algorithms.

Replay for debugging MPI parallel programs

Proceedings of the MPI Developer's Conference

The cyclic debugging approach often fails for parallel programs because parallel programs reveal nondeterministic characteristics due to message race conditions. This paper addresses the execution replay algorithm for debugging MPI parallel programs. The lexical analyzer identifies the MPI events which affect nondeterministic executions, and then an execution is controlled in order to make it equivalent to a reference execution by keeping their orders of events in two executions identical. The proposed replay system uses the logical time stamping algorithm and the derived data types provided by MPI standard. It also presents the method of how to replay the blocking and nonblocking message passing events. The proposed replay system was applied to the bitonic-merge sort and other parallel programs. We found that re-execution has reproducible behavior and the replay system is useful to find the communication errors.

MICE: a prototype MPI implementation in Converse environment

MICE: a prototype MPI implementation in Converse environment

Proceedings of the MPI Developer's Conference

作者： M.A. Bhandarkar L.V. Kale Parallel Programming Laboratory Department of Computer Science University of Illinois Urbana-Champaign Urbana IL USA

The paper describes MICE, a prototype implementation of MPI on the Converse interoperable parallel programming environment. It is based on MPICH, a public-domain implementation of MPI and uses the Abstract Device Interface (ADI) which has been retargeted on top of Converse. MICE makes use of message-managers and allows use of thread-objects to let MPI modules co-exist with other types of computations and communication (such as a library computation in Charm++ or asynchronous computations in multipol) within a single application. It also makes it possible to interoperate PVM (in a restricted form) and MPI modules. Thread-objects make it possible to build multi-threaded MPI programs. This MPI implementation demonstrates that it is possible to provide interoperability without any significant performance degradation.

In this paper, we address the problem of finding a maximum matching for a convex bipartite graph on a mesh-connected computer (MCC). We shall show that this can be done in optimal time on MCC by designing the efficient merge and division schemes in bottom-up and top-down approach respectively. © 1995, Taylor & Francis Group, LLC.
