Download or read book Visualization of Scientific Parallel Programs written by Gerald Tomas and published by Springer Science & Business Media. This book was released on 1994-02-28 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The substantial effort of parallelizing scientific programs is only justified if the resulting codes are efficient. Thus, all types of performance tuning are important to parallel software development. But performance improvements are much more difficult to achieve with parallel programs than with sequential programs. One way to overcome this difficulty is to bring in graphical tools. This monograph covers recent developments in parallel program visualization techniques and tools and demonstrates the application of specific visualization techniques and software tools to scientific parallel programs. The solution of initial value problems of ordinary differential equations, and numerical integration are treated in detail as two important examples.

Book excerpt: This volume gives an overview of the state-of-the-art with respect to the development of all types of parallel computers and their application to a wide range of problem areas. The international conference on parallel computing ParCo97 (Parallel Computing 97) was held in Bonn, Germany from 19 to 22 September 1997. The first conference in this biannual series was held in 1983 in Berlin. Further conferences were held in Leiden (The Netherlands), London (UK), Grenoble (France) and Gent (Belgium). From the outset the aim with the ParCo (Parallel Computing) conferences was to promote the application of parallel computers to solve real life problems. In the case of ParCo97 a new milestone was reached in that more than half of the papers and posters presented were concerned with application aspects. This fact reflects the coming of age of parallel computing. Some 200 papers were submitted to the Program Committee by authors from all over the world. The final programme consisted of four invited papers, 71 contributed scientific/industrial papers and 45 posters. In addition a panel discussion on Parallel Computing and the Evolution of Cyberspace was held. During and after the conference all final contributions were refereed. Only those papers and posters accepted during this final screening process are included in this volume. The practical emphasis of the conference was accentuated by an industrial exhibition where companies demonstrated the newest developments in parallel processing equipment and software. Speakers from participating companies presented papers in industrial sessions in which new developments in parallel computing were reported.

Book excerpt: I felt deeply honored when Professor Sumit Ghosh asked me to write the foreword to his book with an extraordinary perspective. I have long admired him, ?rst as a student leader at Stanford, where he initiated the ?rst IEEE Computer Society’s student chapter, and later as an esteemed and inspiring friend whose transdisciplinary research broadened and enhanced the horizons of practitioners of computer science and engineering, including my own. His ideas, which are derived from his profound vision, deep critical thinking, and personal intuition, reach from information technology to bioscience, as - hibited in this excellent book. To me, an ordinary engineer, it opens up a panoramic view of the Universe of Knowledge that keeps expanding and - spiring,likethegoodIndianproverb,whichsays,“agoodbookinformsyou,an excellent book teaches you, and a great book changes you. ” I sincerely believe that Professor Ghosh’s book will help us change and advance the methods of systems engineering and technology. Vision Inspired vision sees ahead of others what will or may come to be, a vivid, imagined concept or anticipation. An inspired vision personi?es what is good and what like-minded individuals hope for. Our vision is one of creating an Internet of minds, where minds are Web sites or knowledge centers, which create, store, and radiate knowledge through interaction with other minds connected by a universal shared network. This vision will not just hasten the death of distance, but will also - carcerate ignorance.
Download or read book Measurement based Performance Analysis and Modeling of Parallel Systems written by Chitra Natarajan and published by . This book was released on 1996 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CPUs, memory, interconnection network, operating system, runtime system, I/O subsystem, and application characteristics all play an important role in determining the overall performance obtained from a parallel system. However, previous studies have mostly looked at the memory or the OS or the network performance in isolation. A global view of the overheads from different system perspectives has been lacking. In this dissertation, we characterize the overheads for large application benchmarks executing on the Cedar shared-memory parallel system from operating system, runtime system parallelization, and global memory and interconnection network contention perspectives. Parallel systems are often used in multiprogrammed environments. However, the issue of scalability in multiprogrammed shared-memory parallel systems has not been studied before. We investigate the scalability of the Cedar system in multiprogrammed environments and show that there is no performance improvement with scaling for fine-grained loop parallel applications executing in multiprogrammed workloads. We also demonstrate that there is an exponential drop in the overhead due to multiprogramming as the loop granularity is increased. We then propose and implement a self-preemption technique to improve the performance of fine-grained applications in multiprogrammed environments. To balance the processor performance of parallel systems with sufficient I/O performance, several parallel I/O systems have been developed in recent years. However, very little is understood about their performance. We characterize the performance of the PIOUS parallel I/O system on the DEC Alphacluster, via real system measurements, and show that the message passing processing overheads at the compute and I/O nodes limit the throughput that they can sustain. We also use these measurements to provide realistic input parameters to PioSim, a parallel I/O simulation environment we have developed. PioSim offers a number of unique features: (1) two architecture models--remote and local disk architecture models, (2) two usage models--simple and intelligent parallel I/O models, and (3) an application-oriented synthetic parallel I/O workload generator, PioSyn, capable of modeling a wide variety of temporal and spatial application file access patterns. We illustrate the potential of PioSim and PioSyn through experiments on the Alphacluster model, for scientific, database, and videoserver workloads.
