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 Consistent Distributed Storage

Download or read book Consistent Distributed Storage written by Vincent Gramoli and published by Morgan & Claypool Publishers. This book was released on 2021-06-30 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a presentation of several approaches for employing shared memory abstraction in distributed systems, a powerful tool for simplifying the design and implementation of software systems for networked platforms. These approaches enable system designers to work with abstract readable and writable objects without the need to deal with the complexity and dynamism of the underlying platform. The key property of shared memory implementations is the consistency guarantee that it provides under concurrent access to the shared objects. The most intuitive memory consistency model is atomicity because of its equivalence with a memory system where accesses occur serially, one at a time. Emulations of shared atomic memory in distributed systems is an active area of research and development. The problem proves to be challenging, and especially so in distributed message passing settings with unreliable components, as is often the case in networked systems. Several examples are provided for implementing shared memory services with the help of replication on top of message-passing distributed platforms subject to a variety of perturbations in the computing medium.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The papers present in this text survey both distributed shared memory (DSM) efforts and commercial DSM systems. The book discusses relevant issues that make the concept of DSM one of the most attractive approaches for building large-scale, high-performance multiprocessor systems. The authors provide a general introduction to the DSM field as well as a broad survey of the basic DSM concepts, mechanisms, design issues, and systems. The book concentrates on basic DSM algorithms, their enhancements, and their performance evaluation. In addition, it details implementations that employ DSM solutions at the software and the hardware level. This guide is a research and development reference that provides state-of-the art information that will be useful to architects, designers, and programmers of DSM systems.

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 The Consensus Power of Shared memory Distributed Systems

Download or read book The Consensus Power of Shared memory Distributed Systems written by Eric Ruppert and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many asynchronous distributed systems, processes communicate by accessing objects in a shared memory. The ability of systems to solve problems in a fault-tolerant manner depends on the types of objects provided. Here, the wait-free model of fault-tolerance is used: non-faulty processes must run correctly even if other processes experience halting failures. The consensus problem, where processes begin with private inputs and must agree on one of them, has played a central role in analysing the power of distributed systems. This thesis studies the ability of different types of objects to solve consensus. An object type has consensus number 'n' if it can be used (with read/writehsp sp="0.167"hsp sp="0.167"regist ers to solve consensus among 'n' processes but not among ' n'+1 processes. Conditions are given that are necessary and sufficient for an object type to have consensus number 'n'. This characterization applies to two large classes of objects: readable objects and read-modify-write (RMW) objects. An object is readable if processes can read its state without changing the state. For a RMW object, all operations update the state and then return the previous state of the object. When the type is of bounded size, the characterization may be used to decide the question "Does the type 'T' have consensus number 'n'?", which is undecidable for arbitrary types. The characterization is also used to show that different readable and RMW types with consensus number ' n' cannot be used in combination to solve consensus for 'n '+1 processes. Ordinarily, processes may access only one object in shared memory at a time. This thesis also studies how much the consensus number of a type increases in the multi-object and transactional models, where processes can perform operations on up to 'm' of the objects in a single atomic action. These models are much more convenient for programmers to use, since they guarantee that certain blocks of operations will be executed without interruptions from other processes. This thesis establishes bounds on the consensus numbers of multi-objects and transactional objects as a function of 'm' and the consensus numbers of the corresponding single-access types.

Book Distributed Systems for System Architects

Download or read book Distributed Systems for System Architects written by Paulo Veríssimo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary audience for this book are advanced undergraduate students and graduate students. Computer architecture, as it happened in other fields such as electronics, evolved from the small to the large, that is, it left the realm of low-level hardware constructs, and gained new dimensions, as distributed systems became the keyword for system implementation. As such, the system architect, today, assembles pieces of hardware that are at least as large as a computer or a network router or a LAN hub, and assigns pieces of software that are self-contained, such as client or server programs, Java applets or pro tocol modules, to those hardware components. The freedom she/he now has, is tremendously challenging. The problems alas, have increased too. What was before mastered and tested carefully before a fully-fledged mainframe or a closely-coupled computer cluster came out on the market, is today left to the responsibility of computer engineers and scientists invested in the role of system architects, who fulfil this role on behalf of software vendors and in tegrators, add-value system developers, R&D institutes, and final users. As system complexity, size and diversity grow, so increases the probability of in consistency, unreliability, non responsiveness and insecurity, not to mention the management overhead. What System Architects Need to Know The insight such an architect must have includes but goes well beyond, the functional properties of distributed systems.

Book Distributed System Design

Download or read book Distributed System Design written by Jie Wu and published by CRC Press. This book was released on 2017-12-14 with total page 504 pages. 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
