Book excerpt: A general model of computation on a p-parallel processor is proposed, distinguishing clearly between the logical parallelism (p* processes) inherent in a computation, and the physical parallelism (p processors) available in the computer organization. This shows the dependence of performance bounds on both the computation being executed and the computer architecture. We formally derive necessary and sufficient conditions for the maximum attainable speedup of a p-parallel processor over a uniprocessor to be Sp 2 min(:[superscript]FF(p,ln p),:[superscript]FF(p*,ln p*)), where ln p approximates Hp , the pth. harmonic number. We also verify that empirically-derived speedups are 0(:[superscript]FF(p*,ln p*)). Finally, we discuss related performance measures of minimum execution time, maximum efficiency and minimum space-time product.

Available in PDF, EPUB and Kindle. Book excerpt: The Performance of a system depends directly on the time required to perform an operation and number of these operations that can be performed concurrently. High performance computing systems can be designed using parallel processing. The effectiveness of these parallel systems rests primarily on the communication network linking processors and memory modules. Hence, an interconnection network that provides the desired connectivity and performance at minimum cost is required for communication in parallel processing systems. Multistage interconnection networks provide a compromise between shared bus and crossbar networks.

Book excerpt: In the past two decades, breakthroughs in computer technology have made a tremendous impact on optimization. In particular, availability of parallel computers has created substantial interest in exploring the use of parallel processing for solving discrete and global optimization problems. The chapters in this volume cover a broad spectrum of recent research in parallel processing of discrete and related problems. The topics discussed include distributed branch-and-bound algorithms, parallel genetic algorithms for large scale discrete problems, simulated annealing, parallel branch-and-bound search under limited-memory constraints, parallelization of greedy randomized adaptive search procedures, parallel optical models of computing, randomized parallel algorithms, general techniques for the design of parallel discrete algorithms, parallel algorithms for the solution of quadratic assignment and satisfiability problems. The book will be a valuable source of information to faculty, students and researchers in combinatorial optimization and related areas.

Book excerpt: Abstract: "Performance evaluation techniques have become critical indices for both architecture designers and software developers in recent years. Automatic tools are in demand for characterizing performance easily. In addition, a good performance analyzer should be able to point out the amount of performance loss relative to an ideal, where it occurs, and its causes. In this paper, MACS bounds, a hierarchy of bounds for modeling the performance, will be introduced for loop-dominated scientific code. This model successively considers the peak floating-point performance of a Machine of interest (M), the essential operations in a high level Application code of interest (MA), the additional operations in the Compiler-generated workload (MAC), the compiler-generated Schedule for this workload (MACS), and the actual delivered performance. In ascending through the MACS bounds hierarchy from the M bound, the model becomes increasingly constrained as it moves in several steps from potentially deliverable toward actually delivered performance. Each step from one bound to the next quantifies a performance gap associated with particular causes. The bound methodology will then be applied to a multiple-processor system to predict the run-time bound of a scientific application. We present three automatic bound generators, K-MA, KM̲ACSTAT and MACSG̲AP, based on our performance model on the KSR1 Massively Parallel Processing (MPP) machine. Finally, we will use the performance bound models and tools to experiment on a real parallel scientific application running on the KSR1. The analysis results of our selected loops will be illustrated by the MACS bounds hierarchy, machine utilization, and relative speed-up to uniprocessor. These information [sic] will be very useful for improving the performance of the application at the right point."

Available in PDF, EPUB and Kindle. Book excerpt: Scientific computing has often been called the third approach to scientific discovery, emerging as a peer to experimentation and theory. Historically, the synergy between experimentation and theory has been well understood: experiments give insight into possible theories, theories inspire experiments, experiments reinforce or invalidate theories, and so on. As scientific computing has evolved to produce results that meet or exceed the quality of experimental and theoretical results, it has become indispensable.Parallel processing has been an enabling technology in scientific computing for more than 20 years. This book is the first in-depth discussion of parallel computing in 10 years; it reflects the mix of topics that mathematicians, computer scientists, and computational scientists focus on to make parallel processing effective for scientific problems. Presently, the impact of parallel processing on scientific computing varies greatly across disciplines, but it plays a vital role in most problem domains and is absolutely essential in many of them. Parallel Processing for Scientific Computing is divided into four parts: The first concerns performance modeling, analysis, and optimization; the second focuses on parallel algorithms and software for an array of problems common to many modeling and simulation applications; the third emphasizes tools and environments that can ease and enhance the process of application development; and the fourth provides a sampling of applications that require parallel computing for scaling to solve larger and realistic models that can advance science and engineering. This edited volume serves as an up-to-date reference for researchers and application developers on the state of the art in scientific computing. It also serves as an excellent overview and introduction, especially for graduate and senior-level undergraduate students interested in computational modeling and simulation and related computer science and applied mathematics aspects.Contents List of Figures; List of Tables; Preface; Chapter 1: Frontiers of Scientific Computing: An Overview; Part I: Performance Modeling, Analysis and Optimization.

Available in PDF, EPUB and Kindle. Book excerpt: To understand the performance of parallel computers such as ILLIAC IV and C.mmp, the largest speed-up that can be obtained for a given task must be known. If there are k processors, the largest speed-up that can be achieved is k and the authors call this optimal speed-up. The speed-ups in general depend on the parallel decompositon of a particular computing task and the various aspects of the multiprocessing system, including memory contention, process communication, operating system overhead, etc. In this paper, the authors concentrate on the issue of decomposing tasks, and assume that the multiprocessing system is idealized so that it causes no delays at all. It is shown that even under this idealized assumption, there are problems for which, because the parallel decompositions are inherently difficult, the optimal speed-up cannot be achieved.
