Available in PDF, EPUB and Kindle. Book excerpt: This book presents novel and efficient tools, techniques and approaches for reliability evaluation, reliability analysis, and design of reliable communication networks using graph theoretic concepts. In recent years, human beings have become largely dependent on communication networks, such as computer communication networks, telecommunication networks, mobile switching networks etc., for their day-to-day activities. In today's world, humans and critical machines depend on these communication networks to work properly. Failure of these communication networks can result in situations where people may find themselves isolated, helpless and exposed to hazards. It is a fact that every component or system can fail and its failure probability increases with size and complexity. The main objective of this book is to devize approaches for reliability modeling and evaluation of such complex networks. Such evaluation helps to understand which network can give us better reliability by their design. New designs of fault-tolerant interconnection network layouts are proposed, which are capable of providing high reliability through path redundancy and fault tolerance through reduction of common elements in paths. This book covers the reliability evaluation of various network topologies considering multiple reliability performance parameters (two terminal reliability, broadcast reliability, all terminal reliability, and multiple sources to multiple destinations reliability).

This book was released on 1998 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "With parallel machines increasingly taking on critical and complex applications, it is important to make them dependable to ensure their commercial success. Fault-tolerance in the network to accommodate link and node failures is an important step towards this goal. This can be achieved by employing cost-effective fault-tolerant algorithms. However, despite substantial efforts on the theoretical front in developing fault-tolerant routing techniques and architectures, these ideas have not manifested themselves in many commercial platforms. The ramifications of providing fault-tolerant routing in terms of cost and performance is still not clear to the computer architect. Such an insight can only be gained through detailed analysis of a design with realistic workloads. Since no current evaluation platform supports this, previous research on fault-tolerant routing has used synthetic workloads for analyzing performance. This paper presents a comprehensive evaluation testbed for interconnection networks and routing algorithms using real applications. The testbed is flexible enough to implement any network topology and fault-tolerant routing algorithm, and allows the system architect to study the cost versus performance tradeoffs for a range of network parameters. We illustrate its use with one fault-tolerant algorithm and analyze the performance of four shared memory applications with different fault conditions. We also show how the testbed can be used to drive future research in fault-tolerant routing algorithms and architectures, by proposing and evaluating novel architectural enhancements to the network router, called path selection heuristics (PSH). We propose three such schemes and the Least Recently Used (LRU) PSH is shown to give the best performance in the presence of faults."

Available in PDF, EPUB and Kindle. Book excerpt: The need to evaluate computer and communication systems performance and dependability is continuously growing as a consequence of both the increasing complexity of systems and the user requirements in terms of timing behaviour. The 10th International Conference on Modelling Techniques and Tools for C- puter Performance Evaluation, held in Palma in September 1998, was organised with the aim of creating a forum in which both theoreticians and practitioners could interchange recent techniques, tools, and experiences in these areas. This meeting follows the predecessor conferences of this series: 1984 Paris 1988 Palma 1994 Wien 1985 Sophia Antipolis 1991 Torino 1995 Heidelberg 1987 Paris 1992 Edinburgh 1997 Saint Malo The tradition of this conference series continued this year where many high quality papers were submitted. The Programme Committee had a di cult task in selecting the best papers. Many ne papers could not be included in the program due to space constraints. All accepted papers are included in this volume. Also, a set of submissions describing performance modelling tools was transformed into tool presentations and demonstrations. A brief description of these tools is included in this volume. The following table gives the overall statistics for the submissions.

Download or read book Performance Analysis of Multiprocessor Interconnection Networks Using a Burst traffic Model written by Stephen Wilson Turner and published by . This book was released on 1995 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the development and use of a performance analysis methodology suitable for use in the evaluation of multiprocessor interconnection networks. The study is grounded in a detailed evaluation of the Cedar multiprocessor. Using characteristics of the behavior exhibited by the benchmarks studied on that system, a burst-traffic model is developed. The performance predictions of the model for adaptive and oblivious virtual-channel routers used in a 2D torus are compared to those of an open-loop random-traffic model, and significant differences are shown to exist. The design of a novel adaptive router, the Shunt router, is proposed. Proofs of its freedom from deadlock and livelock are provided, showing its suitability for use in the construction of a shared-memory multiprocessor. The burst traffic model is used to drive simple versions of the Shunt router and compare its performance to those of the virtual-channel routers discussed previously. The Shunt router is shown to provide a suitable base for explorations of alterations to the routing algorithms and size of buffers within the router, due to its simplicity of structure. The Shunt router is then augmented with a variety of adaptive routing algorithms. The performance of these algorithms, as well as two oblivious routing algorithms, is evaluated. The results show that structure in oblivious routing is important, and several adaptive routing schemes perform equally well. The Shunt router is also used to evaluate the impact of queue sizes on performance, as well as the interaction between queue lengths and adaptivity. Finally, a traffic-throttling network interface is used, with results that show it is primarily useful in cases of limited router buffering. Analytic performance bounds are developed, and used to place the improvements due to adaptive routing into perspective. These bounds are derived from considerations of the systems topology and the structure of the burst-traffic model. Minimum latency, bisection-width, and a complex mean value analysis model are developed, and each is shown to have utility in different areas of performance prediction and comparison. Given the context of the performance bounds, the adaptive routers are shown to achieve a significant percentage of the potential performance improvement.

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.
