Available in PDF, EPUB and Kindle. Book excerpt: In 1992 we initiated a research project on large scale distributed computing systems (LSDCS). It was a collaborative project involving research institutes and universities in Bologna, Grenoble, Lausanne, Lisbon, Rennes, Rocquencourt, Newcastle, and Twente. The World Wide Web had recently been developed at CERN, but its use was not yet as common place as it is today and graphical browsers had yet to be developed. It was clear to us (and to just about everyone else) that LSDCS comprising several thousands to millions of individual computer systems (nodes) would be coming into existence as a consequence both of technological advances and the demands placed by applications. We were excited about the problems of building large distributed systems, and felt that serious rethinking of many of the existing computational paradigms, algorithms, and structuring principles for distributed computing was called for. In our research proposal, we summarized the problem domain as follows: “We expect LSDCS to exhibit great diversity of node and communications capability. Nodes will range from (mobile) laptop computers, workstations to supercomputers. Whereas mobile computers may well have unreliable, low bandwidth communications to the rest of the system, other parts of the system may well possess high bandwidth communications capability. To appreciate the problems posed by the sheer scale of a system comprising thousands of nodes, we observe that such systems will be rarely functioning in their entirety.

Available in PDF, EPUB and Kindle. Book excerpt: Transactional memory (TM) is an appealing paradigm for concurrent programming on shared memory architectures. With a TM, threads of an application communicate, and synchronize their actions, via in-memory transactions. Transactions are atomic: programmers get the illusion that every transaction executes all its operations instantaneously, at some single and unique point in time. The aim of this book is to provide theoretical foundations for transactional memory.

Available in PDF, EPUB and Kindle. Book excerpt: Transactional memory (TM) is an appealing paradigm for concurrent programming on shared memory architectures. With a TM, threads of an application communicate, and synchronize their actions, via in-memory transactions. Each transaction can perform any number of operations on shared data, and then either commit or abort. When the transaction commits, the effects of all its operations become immediately visible to other transactions; when it aborts, however, those effects are entirely discarded. Transactions are atomic: programmers get the illusion that every transaction executes all its operations instantaneously, at some single and unique point in time. Yet, a TM runs transactions concurrently to leverage the parallelism offered by modern processors. The aim of this book is to provide theoretical foundations for transactional memory. This includes defining a model of a TM, as well as answering precisely when a TM implementation is correct, what kind of properties it can ensure, what are the power and limitations of a TM, and what inherent trade-offs are involved in designing a TM algorithm. While the focus of this book is on the fundamental principles, its goal is to capture the common intuition behind the semantics of TMs and the properties of existing TM implementations.

Download or read book Concurrent Programming Algorithms Principles and Foundations written by Michel Raynal and published by Springer Science & Business Media. This book was released on 2012-12-30 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the most difficult part of concurrent programming, namely synchronization concepts, techniques and principles when the cooperating entities are asynchronous, communicate through a shared memory, and may experience failures. Synchronization is no longer a set of tricks but, due to research results in recent decades, it relies today on sane scientific foundations as explained in this book. In this book the author explains synchronization and the implementation of concurrent objects, presenting in a uniform and comprehensive way the major theoretical and practical results of the past 30 years. Among the key features of the book are a new look at lock-based synchronization (mutual exclusion, semaphores, monitors, path expressions); an introduction to the atomicity consistency criterion and its properties and a specific chapter on transactional memory; an introduction to mutex-freedom and associated progress conditions such as obstruction-freedom and wait-freedom; a presentation of Lamport's hierarchy of safe, regular and atomic registers and associated wait-free constructions; a description of numerous wait-free constructions of concurrent objects (queues, stacks, weak counters, snapshot objects, renaming objects, etc.); a presentation of the computability power of concurrent objects including the notions of universal construction, consensus number and the associated Herlihy's hierarchy; and a survey of failure detector-based constructions of consensus objects. The book is suitable for advanced undergraduate students and graduate students in computer science or computer engineering, graduate students in mathematics interested in the foundations of process synchronization, and practitioners and engineers who need to produce correct concurrent software. The reader should have a basic knowledge of algorithms and operating systems.
Download or read book Concurrent Transactions and Communicators written by Ken Wakita and published by . This book was released on 1995* with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Object-Oriented concurrency model has been recognized as good programming paradigm in concurrent and distributed programming. However, concurrency and synchronization primitives provided by the concurrent object-oriented languages are not expressive enough for complicated communication and synchronization schemes that are required by practical applications. The article proposes a highly extensible computation model that introduces two novel ideas of in concurrent object-oriented computation model: namely transactions and communicators. The concurrent transaction mechanism guarantees collective data integrity of a subcomputation and makes its activity appear atomic relative to the rest of the overall concurrent computation. The communicator is a programmable abstraction of message-based communication protocols. Communicator facilities allow the programmer to add arbitrary communication protocol to the programming language in a seamless manner with respect to the built-in communication primitives. Moreover, by combined use of concurrent transaction and communicators, various atomic communication primitives can be easily developed. A number of examples demonstrate the expressiveness given through these facilities in describing various distributed systems."

This book was released on 1990-04-25 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stepwise refinement method postulates a system construction route that starts with a high-level specification, goes through a number of provably correct development steps, and ends with an executable program. The contributions to this volume survey the state of the art in this extremely active research area. The world's leading specialists in concurrent program specification, verification, and the theory of their refinement present latest research results and surveys of the fields. State-based, algebraic, temporal logic oriented and category theory oriented approaches are presented. Special attention is paid to the relationship between compositionality and refinement for distributed programs. Surveys are given of results on refinement in partial-order based approaches to concurrency. A unified treatment is given of the assumption/commitment paradigm in compositional concurrent program specification and verification, and the extension of these to liveness properties. Latest results are presented on specifying and proving concurrent data bases correct, and deriving network protocols from their specifications.

Download or read book Optimistic concurrency control for nested distributed transactions written by Robert Edward Gruber and published by . This book was released on 1989 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimistic concurrency control techniques allow atomic transactions (or actions for short) to execute without synchronization, relying on commit-time validation to ensure serializability. Previous work in this area has focussed on single-level actions. This thesis extends previous work on optimistic concurrency control to distributed systems with nested actions. The thesis presents two contrasting models for managing nested actions, which we call the fixed action model and the fixed object model. In the fixed action model, an action executes at only a single network node; if an action accesses an object whose storage is provided by another node, it brings a copy of the object to its node. In this model, caching copies of non-local objects can be used to improve performance by reducing the number of non-local object requests. We show that optimistic concurrency control has an advantage over pessimistic concurrency control with respect to this object caching. In the fixed object model, actions can span network nodes: an action at one node can start a nested action at another node. However, an object's state is never moved from the node providing its storage. While there is a clear reason for using optimistic concurrency control for systems following the fixed action model, there is no clear reason for choosing either optimism or pessimism for systems following the fixed object model; however, the development of this model is an important step in the study of hybrid models.

Download or read book Concurrency Control and Reliability in Distributed Systems written by Bharat K. Bhargava and published by Van Nostrand Reinhold Company. This book was released on 1987 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major objective of a distributed system is to provide low coast availability of the resources of the system by localizing access and providing insulation against failures of individual components. Since many users can be concurrently accessing the system, it is essential that a distributed system also provide a high degree of concurrency. Research into algorithms has been focused on concurrency, consistency, failure detection, management of replicated copy, and commitment and termination of transactions. This book is a compilation of a subset of research contributions in the area of concurrency control and reliability in distributed systems, with brief explorations of interesting areas, including theoretical and experimental efforts.
