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."

Book Synopsis Distributed System Design by : Jie Wu

Download or read book Distributed System Design written by Jie Wu. This book was released on 1998-08-06. Available in PDF, EPUB and Kindle. Book excerpt: Future requirements for computing speed, system reliability, and cost-effectiveness entail the development of alternative computers to replace the traditional von Neumann organization. As computing networks come into being, one of the latest dreams is now possible - distributed computing. Distributed computing brings transparent access to as much computer power and data as the user needs for accomplishing any given task - simultaneously achieving high performance and reliability. The subject of distributed computing is diverse, and many researchers are investigating various issues concerning the structure of hardware and the design of distributed software. Distributed System Design defines a distributed system as one that looks to its users like an ordinary system, but runs on a set of autonomous processing elements (PEs) where each PE has a separate physical memory space and the message transmission delay is not negligible. With close cooperation among these PEs, the system supports an arbitrary number of processes and dynamic extensions. Distributed System Design outlines the main motivations for building a distributed system, including: inherently distributed applications performance/cost resource sharing flexibility and extendibility availability and fault tolerance scalability Presenting basic concepts, problems, and possible solutions, this reference serves graduate students in distributed system design as well as computer professionals analyzing and designing distributed/open/parallel systems. Chapters discuss: the scope of distributed computing systems general distributed programming languages and a CSP-like distributed control description language (DCDL) expressing parallelism, interprocess communication and synchronization, and fault-tolerant design two approaches describing a distributed system: the time-space view and the interleaving view mutual exclusion and related issues, including election, bidding, and self-stabilization prevention and detection of deadlock reliability, safety, and security as well as various methods of handling node, communication, Byzantine, and software faults efficient interprocessor communication mechanisms as well as these mechanisms without specific constraints, such as adaptiveness, deadlock-freedom, and fault-tolerance virtual channels and virtual networks load distribution problems synchronization of access to shared data while supporting a high degree of concurrency

Download or read book Reconfigurable Networks-on-Chip written by Sao-Jie Chen. This book was released on 2011-12-15. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive survey of recent progress in the design and implementation of Networks-on-Chip. It addresses a wide spectrum of on-chip communication problems, ranging from physical, network, to application layers. Specific topics that are explored in detail include packet routing, resource arbitration, error control/correction, application mapping, and communication scheduling. Additionally, a novel bi-directional communication channel NoC (BiNoC) architecture is described, with detailed explanation. Written for practicing engineers in need of practical knowledge about the design and implementation of networks-on-chip; Includes tutorial-like details to introduce readers to a diverse range of NoC designs, as well as in-depth analysis for designers with NoC experience to explore advanced issues; Describes a variety of on-chip communication architectures, including a novel bi-directional communication channel NoC. From the Foreword: Overall this book shows important advances over the state of the art that will affect future system design as well as R&D in tools and methods for NoC design. It represents an important reference point for both designers and electronic design automation researchers and developers. --Giovanni De Micheli
