Book Specification and Analysis of Concurrent Systems

Download or read book Specification and Analysis of Concurrent Systems written by Ryszard Janicki and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concurrent systems abound in human experience but their fully adequate conceptualization as yet eludes our most able thinkers. The COSY (ConcurrentSystem) notation and theory was developed in the last decade as one of a number of mathematical approaches for conceptualizing and analyzing concurrent and reactive systems. The COSY approach extends theconventional notions of grammar and automaton from formal language and automata theory to collections of "synchronized" grammars and automata, permitting system specification and analysis of "true" concurrency without reduction to non-determinism. COSY theory is developed to a great level of detail and constitutes the first uniform and self-contained presentationof all results about COSY published in the past, as well as including many new results. COSY theory is used to analyze a sufficient number of typical problems involving concurrency, synchronization and scheduling, to allow the reader to apply the techniques presented tosimilar problems. The COSY model is also related to many alternative models of concurrency, particularly Petri Nets, Communicating Sequential Processes and the Calculus of Communicating Systems.

Book Understanding Concurrent Systems

Download or read book Understanding Concurrent Systems written by A.W. Roscoe and published by Springer Science & Business Media. This book was released on 2010-10-10 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: CSP notation has been used extensively for teaching and applying concurrency theory, ever since the publication of the text Communicating Sequential Processes by C.A.R. Hoare in 1985. Both a programming language and a specification language, the theory of CSP helps users to understand concurrent systems, and to decide whether a program meets its specification. As a member of the family of process algebras, the concepts of communication and interaction are presented in an algebraic style. An invaluable reference on the state of the art in CSP, Understanding Concurrent Systems also serves as a comprehensive introduction to the field, in addition to providing material for a number of more advanced courses. A first point of reference for anyone wanting to use CSP or learn about its theory, the book also introduces other views of concurrency, using CSP to model and explain these. The text is fully integrated with CSP-based tools such as FDR, and describes how to create new tools based on FDR. Most of the book relies on no theoretical background other than a basic knowledge of sets and sequences. Sophisticated mathematical arguments are avoided whenever possible. Topics and features: presents a comprehensive introduction to CSP; discusses the latest advances in CSP, covering topics of operational semantics, denotational models, finite observation models and infinite-behaviour models, and algebraic semantics; explores the practical application of CSP, including timed modelling, discrete modelling, parameterised verifications and the state explosion problem, and advanced topics in the use of FDR; examines the ability of CSP to describe and enable reasoning about parallel systems modelled in other paradigms; covers a broad variety of concurrent systems, including combinatorial, timed, priority-based, mobile, shared variable, statecharts, buffered and asynchronous systems; contains exercises and case studies to support the text; supplies further tools and information at the associated website: http://www.comlab.ox.ac.uk/ucs/. From undergraduate students of computer science in need of an introduction to the area, to researchers and practitioners desiring a more in-depth understanding of theory and practice of concurrent systems, this broad-ranging text/reference is essential reading for anyone interested in Hoare’s CSP.

Book Logics and Models of Concurrent Systems

Download or read book Logics and Models of Concurrent Systems written by Krzysztof R. Apt and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cooperation test [Apt, Francez & de Roever] was originally conceived to capture the proof theoretical analogue of distributed message exchange between disjoint processes, as opposed to the interference freedom test [Owicki & Gries], being the proof theoretical analogue of concurrent communication by means of interference through jointly shared variables. Some authors ([Levin & Gries, Lamport & Schneider, Schlichting and Schneider]) stress that both forms of communication can be proof theoretically characterized using interference freedom only, since proofs for both ultimately amount to an invariance proof of a big global assertion [Ashcroft], invariance of whose parts amounts to interference freedom. Yet I feel that the characteristic nature of the cooperation test is still preserved in the analysis of these authors, because in their analysis of CSP the part dealing with interference freedom specializes to maintenance of a global invariant, the expression of which requires per process the introduction of auxiliary variables which are updated in that process only, thus preserving the concept of disjointness (as opposed to sharing), since now all variables from different processes are disjoint. The cooperation test has been applied to characterize concurrent communication as occurring in Hoare's Communicating Sequential Processes (CSP) [Hoare 2], Ichbiah's ADA [ARM], and Brinch Hansen's Distributed Processes (DP) [Brinch Hansen]. This characterization has been certified through soundness and completeness proofs [Apt 2, Gerth]. As in the interference freedom test this characterization consists of two stages, a local sequential stage and a global stage.

Book Specification and Verification of Concurrent Systems

Download or read book Specification and Verification of Concurrent Systems written by Charles Rattray and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at the BCS-FACS Workshop on Specification and Verification of Concurrent Systems held on 6-8 July 1988, at the University of Stirling, Scotland. Specification and verification techniques are playing an increasingly important role in the design and production of practical concurrent systems. The wider application of these techniques serves to identify difficult problems that require new approaches to their solution and further developments in specification and verification. The Workshop aimed to capture this interplay by providing a forum for the exchange of the experience of academic and industrial experts in the field. Presentations included: surveys, original research, practical experi ence with methods, tools and environments in the following or related areas: Object-oriented, process, data and logic based models and specifi cation methods for concurrent systems Verification of concurrent systems Tools and environments for the analysis of concurrent systems Applications of specification languages to practical concurrent system design and development. We should like to thank the invited speakers and all the authors of the papers whose work contributed to making the Workshop such a success. We were particularly pleased with the international response to our call for papers. Invited Speakers Pierre America Philips Research Laboratories University of Warwick Professor M.

Book Stability Analysis of Concurrent Systems with an Indefinite Number of Processes

Download or read book Stability Analysis of Concurrent Systems with an Indefinite Number of Processes written by Mahesh Girkar and published by . This book was released on 1992 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In a resource-oriented model for concurrent systems ([5, 22]) processes request resources which are controlled by finite state devices called synchronizers. The edges of a synchronizer S are labeled with symbols from an alphabet of operations on resources (denoted by [sigma]). When a process executes an operation, it causes a state change in S.A program P for a process specifies the order in which it executes operations. Thus programs are strings over [sigma]. Concurrency among processes is modeled as an interleaving of their corresponding program strings. We denote by (P[superscript k], S) a concurrent system with k identical processes with program P and a synchronizer S, and by (P, S) a concurrent system with an indefinite number of identical processes. (P[superscript k], S) is weak safe if all interleavings of requests for resources made by the processes can be satisfied by S; it is strong safe if for all partial executions of the processes, S can satisfy some outstanding request for a resource by some process. (P, S) is weak stable (strong stable) iff there exists N> 0 such that (P[superscript k], S) is weak safe (strong safe) for all k [> or =] N. In this report, we formulate questions regarding weak and strong stability and prove their decidability by showing an effective procedure to determine if there exists N> 0 such that (P[superscript k], S) is weak safe (strong safe) for all k [> or =] N. As a corollary of this result, we prove the following full weak (strong) safety theorem: It is decidable if (P[superscript k], S) is weak safe (strong safe) for all k> 0. Finally we show that our machinery is powerful enough to model the standard gas-station customer problem."

Book Concurrent and Real time Systems

Download or read book Concurrent and Real time Systems written by Steve Schneider and published by John Wiley & Sons. This book was released on 1999-11-15 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CSP approach has been widely used in the specification, analysis and verification of concurrent and real-time systems, and for understanding the particular issues that can arise when concurrency is present. It provides a language which enables specifications and designs to be clearly expressed and understood, together with a supporting theory which allows them to be analyzed and shown to be correct. This book supports advanced level courses on concurrency covering timed and untimed CSP. The first half introduces the language of CSP, the primary semantic models (traces, failures, divergences and infinite traces), and their use in the modelling, analysis and verification of concurrent systems. The second half of the book introduces time into the language, brings in the timed semantic model (timed failures) and finally presents the theory of timewise refinement which links the two halves together.

Book The Temporal Logic of Reactive and Concurrent Systems

Download or read book The Temporal Logic of Reactive and Concurrent Systems written by Zohar Manna and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactive systems are computing systems which are interactive, such as real-time systems, operating systems, concurrent systems, control systems, etc. They are among the most difficult computing systems to program. Temporal logic is a formal tool/language which yields excellent results in specifying reactive systems. This volume, the first of two, subtitled Specification, has a self-contained introduction to temporal logic and, more important, an introduction to the computational model for reactive programs, developed by Zohar Manna and Amir Pnueli of Stanford University and the Weizmann Institute of Science, Israel, respectively.
