Book excerpt: Paradigms of Concurrency: Observations, Behaviours, and Systems - a Petri Net View - Ryszard Janicki (McMaster University, CA) Jetty Kleijn (Leiden University, NL) Maciej Koutny (Newcastle University, UK) Lukasz Mikulski (Nicolaus Copernicus University, PL) Concurrency can be studied at different yet consistent levels of abstraction: from individual behavioural observations via more abstract concurrent histories that can be represented by causality structures capturing invariant dependencies between executed actions, to system level constructs such as Petri nets or process algebra expressions. Histories can then be understood as sets of closely related observations. Depending on the nature of the observed relationships between executed actions involved in a single concurrent history, one may identify different concurrency paradigms underpinned by different kinds of causality structures such as partial orders. This book studies fundamental mathematical abstractions to capture and relate observations, histories, and systems. In particular, taking a Petri net view, we present system models fitting various concurrency paradigms and their associated causality structures.

Download or read book Models for Concurrency written by Uri Abraham and published by CRC Press. This book was released on 1999-05-24 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concurrent systems are generally understood in terms of behavioral notions. Models for Concurrency analyzes the subject in terms of events and their temporal relationship rather than on global states. It presents a comprehensive analysis of model theory applied to concurrent protocols, and seeks to provide a theory of concurrency that is both intuitively appealing and rigorously based on mathematical foundations. The book is divided into three main sections. The first introduces the required concepts from model theory, details the structures that are used to model concurrency, gives an in-depth description and explanation of the semantics of a simple language that allows concurrent execution of sequential programs, and deals with the question of resolving executions into higher-level and lower-level granularities. The second and third sections apply the theory developed to practical examples, and an exposition of the producer/consumer problem with details of two solutions is given. The author also deals with message passing, as opposed to shared memory.
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.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract : "We introduce a new invariant semantics of concurrent systems which is a direct generalisation of the causal partial order semantics. Our new semantics overcomes some of the problems encountered when one uses causal partial orders alone. We discuss various aspects of the new invariant model. In particular, we outline how the new invariants can be generated by 1-safe inhibitor Petri nets."

Download or read book Compositionality Concurrency and Partial Correctness written by Job Zwiers and published by Springer. This book was released on 2014-03-12 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hierarchical decomposition of programs into smaller ones is generally considered imperative to master the complexity of large programs. The impact of this principle of program decomposition on the specification and verification of parallel executed programs is the subject of this monograph. Two important yardsticks for verification methods, those of compositionality and modularity, are made precise. The problem of reusing software is addressed by the introduction of the notion of specification adaptation. Within this context, different methods for specifying the observable behavior with respect to partial correctness of communicating processes are considered, and in particular the contrast between the "programs are predicates" and the "programs are predicate transformers" paradigms is shown. The associated formal proof systems are proven sound and complete in various senses with respect to the denotational semantics of the programming language, and they are related to each other to give an in-depth comparison between the different styles of program verification. The programming language TNP used here is near to actual languages like Occam. It combines CCS/CSP style communication based programming with state based programming, and allows dynamically expanding and shrinking networks of processes.
Download or read book A Paradigm for Concurrency Control Protocols for Distributed Databases written by Cornell University. Dept. of Computer Science and published by . This book was released on 1987 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we present a paradigm for concurrency control protocols for distributed replicated databases. This paradigm presents a framework for both developing and analyzing concurrency control protocols, especially those that are designed to handle partitioning failures. Any concurrency control protocol that is an instance of the paradigm must be correct. We show that several known protocols are instances of this paradigm. Consequently, these seemingly unrelated protocols can now be compared and their understanding is simplified. We also present two new concurrency control protocols: the virtual partitions protocol and the accessibility thresholds protocol. Both protocols allow the reading and writing of data in spite of site and communication failures, even when these failures lead to network partitioning. In neither protocol is it ever necessary for a read operation to physically access more than one copy, which makes these protocols desirable for applications where efficient read operations are necessary. The accessibility thresholds protocol provides the database designer with much flexibility in trading off the cost of executing operations and the availability of data objects. Unlike previous protocols, the cost of executing operations on an object is separated from the read and write availability of that object.

Download or read book Concurrency Verification written by Willem-Paul de Roever and published by Cambridge University Press. This book was released on 2012-01-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a systematic and comprehensive introduction both to compositional proof methods for the state-based verification of concurrent programs, such as the assumption-commitment and rely-guarantee paradigms, and to noncompositional methods, whose presentation culminates in an exposition of the communication-closed-layers (CCL) paradigm for verifying network protocols. Compositional concurrency verification methods reduce the verification of a concurrent program to the independent verification of its parts. If those parts are tightly coupled, one additionally needs verification methods based on the causal order between events. These are presented using CCL. The semantic approach followed here allows a systematic presentation of all these concepts in a unified framework which highlights essential concepts. The book is self-contained, guiding the reader from advanced undergraduate level to the state-of-the-art. Every method is illustrated by examples, and a picture gallery of some of the subject's key figures complements the text.
