This book was released on 2008 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interconnection networks have been adopted in multicomputer systems, clusters, or chip multiprocessors (CMPs). Among various routing algorithms in interconnection networks, adaptive routing shows the best performance with most traffic types. In this paper, we propose new adaptive routing algorithms considering the remaining hops in addition to local network status. The proposed algorithms make adaptive decisions only when the remaining hops are less than some threshold and congestion is detected, or they do oblivious routing in other cases. As a result, the number of adaptive decisions is greatly reduced. Consequently our proposed algorithms have less adaptive overhead.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "A deadlock-free fully adaptive routing algorithm for 2D meshes which is optimal in the number of virtual channels required and in the number of restrictions placed on the use of these virtual channels is presented. The routing algorithm imposes less than half as many routing restrictions as any previous fully adaptive routing algorithm. It is also proved that, ignoring symmetry, this routing algorithm is the only fully adaptive routing algorithm that achieves both of these goals. The algorithm exploits the fact that for some adaptive routing algorithms, deadlock freedom is possible even when cycles are present in the channel dependency graph. The implementation of the routing algorithm requires relatively simple router control logic. The routing algorithm requires only the minimum number of virtual channels even when extended to arbitrary dimension meshes, yielding a dramatic reduction in the number of virtual channels needed to support fully adaptive routing. Compared to all previous algorithms which required an exponential number of virtual channels with the dimension of the mesh, the new algorithm requires only 4n - 2 virtual channels for an n-dimensional mesh."
Download or read book An Approach for Deadlock Handling in Torus Network written by Jagdish Chandra Patni and published by LAP Lambert Academic Publishing. This book was released on 2014-11-25 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wormhole routing is a popular switching technique being used in current generation parallel systems. Wormhole Routing is successful to deadlock due to its pipeline operation in the networks. In this book two deadlock free Wormhole Routing algorithms are given for Torus networks. First a simple and efficient minimal adaptive wormhole routing algorithm is presented that recovers from potential deadlocks. This algorithm removes those packets from the network that have stalled for more than a given timeout in a router. Second a fault-tolerant and non-adaptive routing algorithm is proposed for wormhole routed torus networks. This can tolerate any number of non-overlapping rectangular faulty blocks with simple logic and requires only three virtual channels. The algorithm is proved to provide deadlock-livelock free routing with non-overlapping f-rings. The use of such a limited number of virtual channels will significantly reduce the implementation cost of the algorithm in router hardware.

This book was released on 2006-04-11 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE CONTEXT OF PARALLEL PROCESSING The field of digital computer architecture has grown explosively in the past two decades. Through a steady stream of experimental research, tool-building efforts, and theoretical studies, the design of an instruction-set architecture, once considered an art, has been transformed into one of the most quantitative branches of computer technology. At the same time, better understanding of various forms of concurrency, from standard pipelining to massive parallelism, and invention of architectural structures to support a reasonably efficient and user-friendly programming model for such systems, has allowed hardware performance to continue its exponential growth. This trend is expected to continue in the near future. This explosive growth, linked with the expectation that performance will continue its exponential rise with each new generation of hardware and that (in stark contrast to software) computer hardware will function correctly as soon as it comes off the assembly line, has its down side. It has led to unprecedented hardware complexity and almost intolerable dev- opment costs. The challenge facing current and future computer designers is to institute simplicity where we now have complexity; to use fundamental theories being developed in this area to gain performance and ease-of-use benefits from simpler circuits; to understand the interplay between technological capabilities and limitations, on the one hand, and design decisions based on user and application requirements on the other.
Download or read book Networks on Chip written by Axel Jantsch and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the number of processor cores and IP blocks integrated on a single chip is steadily growing, a systematic approach to design the communication infrastructure becomes necessary. Different variants of packed switched on-chip networks have been proposed by several groups during the past two years. This book summarizes the state of the art of these efforts and discusses the major issues from the physical integration to architecture to operating systems and application interfaces. It also provides a guideline and vision about the direction this field is moving to. Moreover, the book outlines the consequences of adopting design platforms based on packet switched network. The consequences may in fact be far reaching because many of the topics of distributed systems, distributed real-time systems, fault tolerant systems, parallel computer architecture, parallel programming as well as traditional system-on-chip issues will appear relevant but within the constraints of a single chip VLSI implementation.
