Book Synopsis Optimisations for Machine Independent AND and OR Parallel Execution of Logic Programs by : B. Ramkumar
Download or read book Optimisations for Machine Independent AND and OR Parallel Execution of Logic Programs written by B. Ramkumar and published by . This book was released on 1990 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: We also describe grainsize control, a simple but extremely effective way of controlling the overhead of parallelization in our scheme. We show how grainsize control will make it possible on our system to achieve speeds comparable to the fastest available sequential compilers on one processor, and yet scale up with increasing number of processors. We also discuss some other optimisations briefly and illustrate the improvements due to the optimisations with some preliminary preformance data."
Book Synopsis Machine Independent "and" and "or" Parallel Execution of Logic Programs by : Balkrishna Ramkumar
Download or read book Machine Independent "and" and "or" Parallel Execution of Logic Programs written by Balkrishna Ramkumar and published by . This book was released on 1991 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parallel machines are becoming increasingly cheap and more easily available. Commercial companies have already announced MIMD machines with more than 8000 processors. This prompts three questions: Should the programmer have to rewrite existing software for each new machine that comes along? Should it be necessary for the programmer to have intimate knowledge of the target machine in order to program it efficiently? Is it necessary for the programmer to identify the parallelism in programs explicitly? Our thesis is that the answer is 'no' on all three counts. We demonstrate that it is possible for users to write parallel programs in a machine independent manner. We address this problem at two levels. We first describe the design and implementation of a parallel run time support system called the Chare kernel that provides a uniform interface to the programmer on the class of MIMD machines. This support system makes it possible for programmers to write machine independent programs efficiently. We choose the logic programming paradigm where a high level specification of the problem is possible and it is amenable to the implicit detection of parallelism. We have designed and implemented a compiler that exploits AND and OR parallelism in logic programs. We have developed an emulator for abstract machine code generated by our compiler as an application on the Chare kernel which runs without modification on shared memory and nonshared memory machines alike. This thesis discusses addresses algorithmic issues relating to the design and implementation of an efficient parallel Prolog compiler on both shared and nonshared machines. This work differs significantly from most other related research, in part due to their dependence on a global memory address space. This work is the first to demonstrate that nonshared machines like the Intel and NCUBE hypercubes can be exploited effectively for the parallel execution of logic programs. It also provides a convincing demonstration of machine independent parallel programming.
Book Synopsis Multiprocessor Execution of Logic Programs by : Gopal Gupta
Download or read book Multiprocessor Execution of Logic Programs written by Gopal Gupta and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiprocessor Execution of Logic Programs addresses the problem of efficient implementation of logic programming languages, specifically Prolog, on multiprocessor architectures. The approaches and implementations developed attempt to take full advantage of sequential implementation technology developed for Prolog (such as the WAM) while exploiting all forms of control parallelism present in logic programs, namely, or-parallelism, independent and-parallelism and dependent and-parallelism. Coverage includes a thorough survey of parallel implementation techniques and parallel systems developed for Prolog. Multiprocessor Execution of Logic Programs is recommended for people implementing parallel logic programming systems, parallel symbolic systems, parallel AI systems, and parallel theorem proving systems. It will also be useful to people who wish to learn about the implementation of parallel logic programming systems.
Book Synopsis Parallel Execution of Logic Programs by : John S. Conery
Download or read book Parallel Execution of Logic Programs written by John S. Conery and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an updated version of my Ph.D. dissertation, The AND/OR Process Model for Parallel Interpretation of Logic Programs. The three years since that paper was finished (or so I thought then) have seen quite a bit of work in the area of parallel execution models and programming languages for logic programs. A quick glance at the bibliography here shows roughly 50 papers on these topics, 40 of which were published after 1983. The main difference between the book and the dissertation is the updated survey of related work. One of the appendices in the dissertation was an overview of a Prolog implementation of an interpreter based on the AND/OR Process Model, a simulator I used to get some preliminary measurements of parallelism in logic programs. In the last three years I have been involved with three other implementations. One was written in C and is now being installed on a small multiprocessor at the University of Oregon. Most of the programming of this interpreter was done by Nitin More under my direction for his M.S. project. The other two, one written in Multilisp and the other in Modula-2, are more limited, intended to test ideas about implementing specific aspects of the model. Instead of an appendix describing one interpreter, this book has more detail about implementation included in Chapters 5 through 7, based on a combination of ideas from the four interpreters.

This book was released on 1999 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main areas of research in logic programming is the design and implementation of sequential and parallel (constraint) logic programming systems. This research goes broadly from the design and specification of novel implementation technology to its actual evaluation in real life situations. This book includes topics such as the analysis and description of implemented systems (or currently under implementation) and their associated techniques, problems found in their development or design, and steps taken towards the solution of these problems.
Book Synopsis Concepts, Design, and Performance Analysis of a Parallel Prolog Machine by : Joachim Beer
Download or read book Concepts, Design, and Performance Analysis of a Parallel Prolog Machine written by Joachim Beer and published by Springer Science & Business Media. This book was released on 1989-12-13 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents a novel execution model for the parallel execution of standard sequential Prolog. In this execution model Prolog procedure calls can be efficiently pipelined, and the author shows how even fully deterministic Prolog programs can be effectively mapped onto the proposed architecture. The design is based on a highly optimized abstract Prolog specific instruction set. A special feature of this work is a sophisticated classification scheme for Prolog variables which substantially reduces the overhead for unification with occur-check. To support the model an architecture consisting of a circular pipeline of independent processors has been designed. This pipeline has been designed to work as a co-processor to a UNIX based workstation. In contrast to other attempts to execute sequential Prolog in parallel, the proposed model does not restrict the use of any of the standard Prolog language features. The book gives a full account of the execution model, the system architecture, and the abstract Prolog instruction set.

Book Synopsis Handbook of Parallel Constraint Reasoning by : Youssef Hamadi
Download or read book Handbook of Parallel Constraint Reasoning written by Youssef Hamadi and published by Springer. This book was released on 2018-04-05 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book presenting a broad overview of parallelism in constraint-based reasoning formalisms. In recent years, an increasing number of contributions have been made on scaling constraint reasoning thanks to parallel architectures. The goal in this book is to overview these achievements in a concise way, assuming the reader is familiar with the classical, sequential background. It presents work demonstrating the use of multiple resources from single machine multi-core and GPU-based computations to very large scale distributed execution platforms up to 80,000 processing units. The contributions in the book cover the most important and recent contributions in parallel propositional satisfiability (SAT), maximum satisfiability (MaxSAT), quantified Boolean formulas (QBF), satisfiability modulo theory (SMT), theorem proving (TP), answer set programming (ASP), mixed integer linear programming (MILP), constraint programming (CP), stochastic local search (SLS), optimal path finding with A*, model checking for linear-time temporal logic (MC/LTL), binary decision diagrams (BDD), and model-based diagnosis (MBD). The book is suitable for researchers, graduate students, advanced undergraduates, and practitioners who wish to learn about the state of the art in parallel constraint reasoning.
Book Synopsis Parallel Execution of Logic Programs by : Anthony Beaumont
Download or read book Parallel Execution of Logic Programs written by Anthony Beaumont and published by Springer. This book was released on 1991-12-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Logic programming refers to execution of programs written in Horn logic. Among the advantages of this style of programming are its simple declarativeand procedural semantics, high expressive power and inherent nondeterminism. The papers included in this volume were presented at the Workshop on Parallel Logic Programming held in Paris on June 24, 1991, as part of the 8th International Conference on Logic Programming. The papers represent the state of the art in parallel logic programming, and report the current research in this area, including many new results. The three essential issues in parallel execution of logic programs which the papers address are: - Which form(s) of parallelism (or-parallelism, and-parallelism, stream parallelism, data-parallelism, etc.) will be exploited? - Will parallelism be explicitly programmed by programmers, or will it be exploited implicitly without their help? - Which target parallel architecture will the logic program(s) run on?
