Seban and published by . This book was released on 1985 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two methods are used to speed up the execution of a computational task. One is new technology development and the other is the exploitation of parallelism in the computation. To take an advantage of the parallelism in a task requires the utilization of parallel computer architectures. At a certain high level of abstraction a parallel computer system is represented as a graph where the nodes represent processors, memories, or other devices, and the edges represent the communication links. In this thesis the following problems of parallel processing are studied. First is a theoretical study of topological properties of interconnection networks. Second is a case study of a network design for a real-time system. Lastly, the use of SIMD(Single Instruction Stream Multiple Data Stream) networks for performing 'shuffles'. A general model that can be used to describe networks and systems with arbitrary topologies is developed. Based upon the of morphism of groups, the concept of morphism of systems is developed. The morphism of systems is called quasimorphism and allows a method of comparison between topologically arbitrary parallel computer systems. The quasimorphism is used to study the emulation of one system by another.

This book was released on 2013-04-17 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of very large scale integrated circuit technology has enabled the construction of very complex and large interconnection networks. By most accounts, the next generation of supercomputers will achieve its gains by increasing the number of processing elements, rather than by using faster processors. The most difficult technical problem in constructing a supercom puter will be the design of the interconnection network through which the processors communicate. Selecting an appropriate and adequate topological structure of interconnection networks will become a critical issue, on which many research efforts have been made over the past decade. The book is aimed to attract the readers' attention to such an important research area. Graph theory is a fundamental and powerful mathematical tool for de signing and analyzing interconnection networks, since the topological struc ture of an interconnection network is a graph. This fact has been univer sally accepted by computer scientists and engineers. This book provides the most basic problems, concepts and well-established results on the topological structure and analysis of interconnection networks in the language of graph theory. The material originates from a vast amount of literature, but the theory presented is developed carefully and skillfully. The treatment is gen erally self-contained, and most stated results are proved. No exercises are explicitly exhibited, but there are some stated results whose proofs are left to the reader to consolidate his understanding of the material.

Download or read book Principles and Practices of Interconnection Networks written by William James Dally and published by Elsevier. This book was released on 2004-03-06 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest challenges faced by designers of digital systems is optimizing the communication and interconnection between system components. Interconnection networks offer an attractive and economical solution to this communication crisis and are fast becoming pervasive in digital systems. Current trends suggest that this communication bottleneck will be even more problematic when designing future generations of machines. Consequently, the anatomy of an interconnection network router and science of interconnection network design will only grow in importance in the coming years.This book offers a detailed and comprehensive presentation of the basic principles of interconnection network design, clearly illustrating them with numerous examples, chapter exercises, and case studies. It incorporates hardware-level descriptions of concepts, allowing a designer to see all the steps of the process from abstract design to concrete implementation. Case studies throughout the book draw on extensive author experience in designing interconnection networks over a period of more than twenty years, providing real world examples of what works, and what doesn't. Tightly couples concepts with implementation costs to facilitate a deeper understanding of the tradeoffs in the design of a practical network. A set of examples and exercises in every chapter help the reader to fully understand all the implications of every design decision.

Book excerpt: Recent innovation in the field of Very Large Scale Integration has resulted into fabrication of high speed processors. The sequential computers, equipped with such high speed processors, are unable to meet the challenges of various real-life and real- time computational problems in the areas of image processing, climate modeling, remote sensing, medical science etc., that require to process massive volume of data. Parallel processing is one of the most appropriate technologies that can meet the challenges of such application areas. A variety of numeric and non-numeric problems are often required to be solved in the above mentioned areas. Prefix computation, polynomial root finding, matrix-matrix multiplication, conflict graph construction are some of the very important computations, which are frequently used for solving such problems. In this thesis, we mainly focus on the design of parallel algorithms for such computations to map them efficiently on suitable interconnection networks. We also study a specific interconnection network, called OTIS-Mesh of trees. We establish its various topological properties and propose several parallel algorithms on it.

Download or read book Interconnection Networks and Mapping and Scheduling Parallel Computations written by Derbiau Frank Hsu and published by American Mathematical Soc.. This book was released on 1995 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interconnection network is one of the most basic components of a massively parallel computer system. Such systems consist of hundreds or thousands of processors interconnected to work cooperatively on computations. One of the central problems in parallel computing is the task of mapping a collection of processes onto the processors and routing network of a parallel machine. Once this mapping is done, it is critical to schedule computations within and communication among processors so that the necessary inputs for a process are available where and when the process is scheduled to be computed. This book contains the refereed proceedings of a DIMACS Workshop on Massively Parallel Computation, held in February 1994. The workshop brought together researchers from universities and laboratories, as well as practitioners involved in the design, implementation, and application of massively parallel systems. Focusing on interconnection networks of parallel architectures of today and of the near future, the book includes topics such as network topologies, network properties, message routing, network embeddings, network emulation, mappings, and efficient scheduling.

This book was released on 1999 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of computers with hundreds or thousands of processors and capability for very high performance is absolutely essential for many computation problems, such as weather modeling, fluid dynamics, and aerodynamics. Several interconnection networks have been proposed for parallel computers. Nevertheless, the majority of them are plagued by rather poor topological properties that result in large memory latencies for DSM (Distributed Shared-Memory) computers. On the other hand, scalable networks with very good topological properties are often impossible to build because of their prohibitively high VLSI (e.g., wiring) complexity. Such a network is the generalized hypercube (GH). The GH supports full-connectivity of its nodes in each dimension and is characterized by outstanding topological properties. In addition, low-dimensional GHs have very large bisection widths. We propose in this dissertation a new class of processor interconnections, namely HOWs (Highly Overlapping Windows), that are more generic than the GH, are highly scalable, and have comparable performance. We analyze the communications capabilities of 2-D HOW systems and demonstrate that in practical cases HOW systems perform much better than binary hypercubes for important communications patterns. These properties are in addition to the good scalability and low hardware complexity of HOW systems. We present algorithms for one-to-one, one-to-all broadcasting, all-to-all broadcasting, one-to-all personalized, and all-to-all personalized communications on HOW systems. These algorithms are developed and evaluated for several communication models. In addition, we develop techniques for the efficient embedding of popular topologies, such as the ring, the torus, and the hypercube, into 1-D and 2-D HOW systems. The objective is to show that 2-D HOW systems are not only scalable and easy to implement, but they also result in good embedding of several classical topologies.

Book excerpt: Abstract: "The star and pancake networks were proposed in 1986 as attractive alternatives to the popular n-cube for interconnecting processors on a parallel computer. In this paper, we present the following results concerning these two interconnection networks: (1) several topological and embedding properties of both networks, in particular a decomposition that partitions a star network of n! nodes into (n-2)! vertex disjoint cycles of length (n-1)n each, and a decomposition that partitions a star or pancake network of n! nodes into (n-1)! vertex disjoint paths of length n each; (2) a number of schemes for routing data on both networks; (3) new broadcasting and prefix sum algorithms, applicable to both networks; and (4) an algorithm for sorting K elements on a pancake interconnection network with n! nodes, where K[> or =]n!, and each node holds at most [formula] elements; the algorithm runs in O(NlogN(nlogn) + Nn3logn) time, which is O(n3logn) when K = n!."
