Available in PDF, EPUB and Kindle. Book excerpt: Water scale integration (WSI) promises to realize a complete multiprocessing system on the same wafer and eliminates the expensive steps required to dice and bond. The fundamental belief is that the internal connection between chips on the same wafer are more reliable and have a smaller propagation delay than external connections. However, achieving a high yield has proven to be a major challenge. Rather than aiming for 100% yield, the realistic solution is to determine the defective components on the wafer and replace them with spares. Which means, the design should be tolerant to faults developed during the manufacturing process. Moreover, faults occur during system operation, be it component failure, improper operation, or environmental factors. Therefore, a mean to detect these unexpected faults and recover from them is necessary to minimize down time and unavailability. Long and periodic system downs are a luxury that cannot be afforded for computers used in critical applications. In this paper, we show that the introduction of optical interconnection techniques into a multiprocessor environmental (e.g. the Programmable Optoelectronic Multiprocessor, POEM) enables efficient implementation of fault-tolerant techniques.

Available in PDF, EPUB and Kindle. Book excerpt: The first area of research is Data-Flow Clustering. In synchronous circuits (described in terms of registers and combinational nodes) it is known that the feedback loops are dominant in determining the achievable clock period for the circuit. More precisely, the maximum delay to register ratio over all loops in the circuit (called the iteration bound) is a lower bound on the clock period. Furthermore, if the combinational nodes are fine-grained in nature, the iteration bound very closely reflects the achievable clock period through retiming. However, because of size constraints it is often necessary to partition such a circuit into multiple modules (for example FPGA's). The second area of research is network partitioning. We study the classical problem of finding the Minimum-Cut in an undirected graph, given source and sink nodes, s and t. We reformulate the problem as a continuous placement problem. We show the correspondence between the Min-Cut problem and the placement problem which is then solved iteratively using gradient methods. In addition, this method has good potential for efficient parallel implementation. We provide experimental data on the effectiveness of our approach.

This book was released on 1992 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our objective during the funding period, July 1, 1989 to September 15, 1992, was to investigate random like interconnects, fault tolerance, and grain size studies for optoelectronic parallel processors. The major focus has been in the design and analysis of parallel optoelectronic interconnection networks. Two major areas were identified and researched. The first involves the design, analysis, and simulation of perfect shuffle-based optoelectronic multistage interconnection interconnection networks(MINs) for highly parallel computers. The objective was first to perform a quantitative performance comparison-between optoelectronic and VLSI implementations of multistage interconnection networks (MINs). The next task was to optimize the optoelectronic MIN with respect to architectural and technological parameters. The final goal was to design and simulate a MIN system that could provide a complete set of communication and synchronization services.

Download or read book Foundations of Dependable Computing written by Gary M. Koob and published by Springer Science & Business Media. This book was released on 2007-07-23 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foundations of Dependable Computing: Models and Frameworks for Dependable Systems presents two comprehensive frameworks for reasoning about system dependability, thereby establishing a context for understanding the roles played by specific approaches presented in this book's two companion volumes. It then explores the range of models and analysis methods necessary to design, validate and analyze dependable systems. A companion to this book (published by Kluwer), subtitled Paradigms for Dependable Applications, presents a variety of specific approaches to achieving dependability at the application level. Driven by the higher level fault models of Models and Frameworks for Dependable Systems, and built on the lower level abstractions implemented in a third companion book subtitled System Implementation, these approaches demonstrate how dependability may be tuned to the requirements of an application, the fault environment, and the characteristics of the target platform. Three classes of paradigms are considered: protocol-based paradigms for distributed applications, algorithm-based paradigms for parallel applications, and approaches to exploiting application semantics in embedded real-time control systems. Another companion book (published by Kluwer) subtitled System Implementation, explores the system infrastructure needed to support the various paradigms of Paradigms for Dependable Applications. Approaches to implementing support mechanisms and to incorporating additional appropriate levels of fault detection and fault tolerance at the processor, network, and operating system level are presented. A primary concern at these levels is balancing cost and performance against coverage and overall dependability. As these chapters demonstrate, low overhead, practical solutions are attainable and not necessarily incompatible with performance considerations. The section on innovative compiler support, in particular, demonstrates how the benefits of application specificity may be obtained while reducing hardware cost and run-time overhead.
Download or read book Fault Tolerance written by Peter A. Lee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of a new version of any book is a daunting task, as many authors will recognise. In the field of computer science, the task is made even more daunting by the speed with which the subject and its supporting technology move forward. Since the publication of the first edition of this book in 1981 much research has been conducted, and many papers have been written, on the subject of fault tolerance. Our aim then was to present for the first time the principles of fault tolerance together with current practice to illustrate those principles. We believe that the principles have (so far) stood the test of time and are as appropriate today as they were in 1981. Much work on the practical applications of fault tolerance has been undertaken, and techniques have been developed for ever more complex situations, such as those required for distributed systems. Nevertheless, the basic principles remain the same.
