Book Fault Tolerant Parallel and Distributed Systems

Download or read book Fault Tolerant Parallel and Distributed Systems written by Dimiter R. Avresky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most important use of computing in the future will be in the context of the global "digital convergence" where everything becomes digital and every thing is inter-networked. The application will be dominated by storage, search, retrieval, analysis, exchange and updating of information in a wide variety of forms. Heavy demands will be placed on systems by many simultaneous re quests. And, fundamentally, all this shall be delivered at much higher levels of dependability, integrity and security. Increasingly, large parallel computing systems and networks are providing unique challenges to industry and academia in dependable computing, espe cially because of the higher failure rates intrinsic to these systems. The chal lenge in the last part of this decade is to build a systems that is both inexpensive and highly available. A machine cluster built of commodity hardware parts, with each node run ning an OS instance and a set of applications extended to be fault resilient can satisfy the new stringent high-availability requirements. The focus of this book is to present recent techniques and methods for im plementing fault-tolerant parallel and distributed computing systems. Section I, Fault-Tolerant Protocols, considers basic techniques for achieving fault-tolerance in communication protocols for distributed systems, including synchronous and asynchronous group communication, static total causal order ing protocols, and fail-aware datagram service that supports communications by time.

Book Hardware and Software Architectures for Fault Tolerance

Download or read book Hardware and Software Architectures for Fault Tolerance written by Michel Banatre and published by Springer Science & Business Media. This book was released on 1994-02-28 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fault tolerance has been an active research area for many years. This volume presents papers from a workshop held in 1993 where a small number of key researchers and practitioners in the area met to discuss the experiences of industrial practitioners, to provide a perspective on the state of the art of fault tolerance research, to determine whether the subject is becoming mature, and to learn from the experiences so far in order to identify what might be important research topics for the coming years. The workshop provided a more intimate environment for discussions and presentations than usual at conferences. The papers in the volume were presented at the workshop, then updated and revised to reflect what was learned at the workshop.

Book Fault Tolerance Techniques for High Performance Computing

Download or read book Fault Tolerance Techniques for High Performance Computing written by Thomas Herault and published by Springer. This book was released on 2015-07-01 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely text presents a comprehensive overview of fault tolerance techniques for high-performance computing (HPC). The text opens with a detailed introduction to the concepts of checkpoint protocols and scheduling algorithms, prediction, replication, silent error detection and correction, together with some application-specific techniques such as ABFT. Emphasis is placed on analytical performance models. This is then followed by a review of general-purpose techniques, including several checkpoint and rollback recovery protocols. Relevant execution scenarios are also evaluated and compared through quantitative models. Features: provides a survey of resilience methods and performance models; examines the various sources for errors and faults in large-scale systems; reviews the spectrum of techniques that can be applied to design a fault-tolerant MPI; investigates different approaches to replication; discusses the challenge of energy consumption of fault-tolerance methods in extreme-scale systems.

Book Concurrent Crash Prone Shared Memory Systems

Download or read book Concurrent Crash Prone Shared Memory Systems written by Michel Raynal and published by Morgan & Claypool Publishers. This book was released on 2022-03-22 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theory is what remains true when technology is changing. So, it is important to know and master the basic concepts and the theoretical tools that underlie the design of the systems we are using today and the systems we will use tomorrow. This means that, given a computing model, we need to know what can be done and what cannot be done in that model. Considering systems built on top of an asynchronous read/write shared memory prone to process crashes, this monograph presents and develops the fundamental notions that are universal constructions, consensus numbers, distributed recursivity, power of the BG simulation, and what can be done when one has to cope with process anonymity and/or memory anonymity. Numerous distributed algorithms are presented, the aim of which is being to help the reader better understand the power and the subtleties of the notions that are presented. In addition, the reader can appreciate the simplicity and beauty of some of these algorithms.

Book Synchronization and Fault Tolerance Techniques in Concurrent Shared Memory Systems

Download or read book Synchronization and Fault Tolerance Techniques in Concurrent Shared Memory Systems written by Sahil Dhoked and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mutual exclusion is one of the most commonly used techniques to handle contention in concurrent systems. Traditionally, mutual exclusion algorithms have been designed under the assumption that a process does not fail while acquiring/releasing a lock or while executing its critical section. However, failures do occur in real life, potentially leaving the lock in an inconsistent state. This gives rise to the problem of recoverable mutual exclusion (RME) that involves designing a mutual exclusion (ME) algorithm that can tolerate failures, while maintaining safety and liveness properties. With the recent development of NVRAM (non-volatile random-access memory) technologies, there is renewed interest in the RME problem. The NVRAM technology is a combination of the low latency of traditional random-access memory with the high persistence of disk storage media. NVRAMs can be used to provide near-instantaneous recovery to many problems including the RME problem. This work describes techniques for designing efficient algorithms to solve the RME problem under two different failure models, independent failure model and system-wide failure model, depending on whether processes fail independently or simultaneously. Additionally, especially for systems with low memory capacity, this work describes fault-tolerant techniques for reclaiming memory, in case there is no built-in support for garbage collection. The primary measure of an RME algorithm is its performance. Performance of any ME algorithm, including an RME algorithm, is measured by the number of remote memory references (RMRs) made by a process—for acquiring and releasing a lock as well as recovering the lock structure after a failure. Loosely speaking, it represents the number of expensive shared memory instructions. In this work, two models of RMR computation are considered: (a) the CC model, and (b) the DSM model. The results mentioned in this work are applicable to both of these computation models. For the independent failure model, this work presents a framework that transforms any algorithm that solves the RME problem into an algorithm whose performance (in terms of RMRs) can simultaneously adapt to (a) the number of processes competing for the lock, as well as (b) the number of failures that have occurred in the recent past, while maintaining the correctness and performance properties of the underlying RME algorithm. Assume that, for n processes, the RMR complexity of the underlying RME algorithm is R(n). Then, this framework yields an RME algorithm for which the RMR complexity is given by O(min{c, ̈ √ F + 1, R(n)}), where ̈c denotes the point contention (number of active processes) and F denotes the number of failures in the recent past. The system-wide failure model is a special case of the independent failure model that assumes that failures only occur simultaneously. For example, a power outage is a real life example of such a failure. This model makes a stronger assumption than just multiple independent failures. This assumption is leveraged with enhanced RME algorithms presented under this model. For the system-wide failure model, this work presents optimal RME algorithms (and related transformations) whose worst-case performance yield a O(1) RMR complexity. The fault-tolerant memory reclamation algorithm provides novel techniques to bound the worst-case space complexity of RME algorithms. The techniques used are general enough that they may also be employed to bound the space complexity of other RME algorithms. Its RMR complexity is merely an additive factor of O(1).
