Available in PDF, EPUB and Kindle. Book excerpt: This unique text/reference provides an overview of crossbar-based interconnection networks, offering novel perspectives on these important components of high-performance, parallel-processor systems. A particular focus is placed on solutions to the blocking and scalability problems. Topics and features: introduces the fundamental concepts in interconnection networks in multi-processor systems, including issues of blocking, scalability, and crossbar networks; presents a classification of interconnection networks, and provides information on recognizing each of the networks; examines the challenges of blocking and scalability, and analyzes the different solutions that have been proposed; reviews a variety of different approaches to improve fault tolerance in multistage interconnection networks; discusses the scalable crossbar network, which is a non-blocking interconnection network that uses small-sized crossbar switches as switching elements. This invaluable work will be of great benefit to students, researchers and practitioners interested in computer networks, parallel processing and reliability engineering. The text is also essential reading for course modules on interconnection network design and reliability.

Available in PDF, EPUB and Kindle. Book excerpt: The performance of most digital systems today is limited by their communication or interconnection, not by their logic or memory. As designers strive to make more efficient use of scarce interconnection bandwidth, interconnection networks are emerging as a nearly universal solution to the system-level communication problems for modern digital systems. Interconnection networks have become pervasive in their traditional application as processor-memory and processor-processor interconnect. Point-to-point interconnection networks have replaced buses in an ever widening range of applications that include on-chip interconnect, switches and routers, and I/O systems. In this book, the authors present in a structured way the basic underlying concepts of most interconnection networks and provide representative solutions that have been implemented in the industry or proposed in the research literature. * Gives a coherent, comprehensive treatment of the entire field * Presents a formal statement of the basic concepts, alternative design choices, and design trade-offs * Provides thorough classifications, clear descriptions, accurate definitions, and unified views to structure the knowledge on interconnection networks * Focuses on issues critical to designers

Download or read book Design and Evaluation of Efficient Collective Communications on Modern Interconnects and Multi core Clusters written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two driving forces behind high-performance clusters are the availability of modern interconnects and the advent of multi-core systems. As multi-core clusters become commonplace, where each core will run at least one process with multiple intra-node and inter-node connections to several other processes, there will be immense pressure on the interconnection network and its communication system software. Many parallel scientific applications use Message Passing Interface (MPI) collective communications intensively. Therefore, efficient and scalable implementation of MPI collective operations is critical to the performance of applications running on clusters. In this dissertation, I propose and evaluate a number of efficient collective communication algorithms that utilize the modern features of Quadrics and InfiniBand interconnects as well as the availability of multiple cores on emerging clusters. To overcome bandwidth limitations and to enhance fault tolerance, using multiple independent networks known as multi-rail networks is very promising. Quadrics multi-rail QsNetII network is constructed using multiple network interface cards (NICs) per node, where each NIC is connected to a rail. I design and evaluate a number of Remote Direct Memory Access (RDMA) based multi-port collective operations on multi-rail QsNetII network. I also extend the gather and allgather algorithms to be shared memory aware for small to medium messages. The algorithms prove to be much more efficient than the native Quadrics MPI implementation. ConnectX is the newest generation of InfiniBand host channel adapters from Mellanox Technologies. I provide evidence that ConnectX achieves scalable performance for simultaneous communication over multiple connections. Utilizing this ability of ConnectX cards, I propose a number of RDMA based multi-connection and multi-core aware allgather algorithms at the MPI level. My algorithms are devised to target different message sizes, and the performance result.

Available in PDF, EPUB and Kindle. Book excerpt: Technological Advances and Problems of High Performance Communications An ecosystem of solutions along a stack of technology layers Cohesively collecting state-of-the-art contributions from leading researchers in industry, national laboratories, and academia, Attaining High Performance Communications: A Vertical Approach discusses various issues pertaining to high performance communications in a particular layer of a vertical stack. It explores efficient interconnection hardware, the architectural aspects of network adapters and their integration with processor cores, the design of scalable and robust high performance end-to-end communications services and protocols, and system services and tools for new multi-core environments. No single solution applied at one particular layer can help applications solve all performance-related issues with communication services. Instead, this book shows that a coordinated effort is needed among the layers. It covers many different types of technologies and layers across the stack, from the architectural features of the hardware, through the protocols and their implementation in operating system kernels, to the manner in which application services and middleware are using underlying platforms. The book also describes key developments in high-end platforms, high performance interconnection fabrics and communication libraries, and multi- and many-core systems. This volume addresses the challenges involved in emerging types of communications applications, platforms, and services. Examining each layer in the vertical stack, it illustrates how to eliminate bottlenecks and provide optimization opportunities.

Available in PDF, EPUB and Kindle. Book excerpt: The advent of new technologies brings revolutions in the fields of VLSI design and high performance computing. On one hand, the increasing number of processing elements, both in on-chip multi-core systems and supercomputer systems, demands high bandwidth communications. On the other hand, the performance of the system, usually measured by the latency and power consumption, is gradually being dominated by the interconnection networks. These facts raise challenges in synthesizing and optimizing interconnection networks. In this dissertation, we study methodologies and algorithms to perform the interconnection network synthesis and optimization in both on-chip networks and supercomputer systems. We explore a wide range of network topologies and physical implementations, and evaluate the performance of multi-commodity flow (MCF) algorithms. We design efficient approximation schemes to solve different variations of MCF problems, which incorporate different practical constraints. The automated design flows discover much larger design space than the traditional methods and therefore achieve promising results. In the study of Network-on-Chip (NoC), we are optimizing the communication latency and power consumption, which are two competing design objectives. With an improved fully polynomial approximation algorithm, power optimal design of a structured 8x8 NoC can be found for given average latency constraints with certain communication bandwidth requirements. Our methodology explores a large number of topologies, introduces a variety of wire styles into NoC design, and incorporates latency constraints and power minimization objectives into a unified MCF model, with simultaneous optimization on network topologies, physical embedding, and interconnect wire styles. The results demonstrate the strengths of the optimized networks and indicate the clear trend of power and latency tradeoffs. In the synthesis and optimization of networks in supercomputer systems, we use the packaging framework of the Blue Gene/L supercomputer as an example to demonstrate the advantages of our design flow, which has incorporated real design issues, such as board dimensions and pin numbers. Using real benchmark traces, the experiments show that the best topologies identified by our algorithm can achieve better average latency compared to the existing 3-dimensional torus networks.
