Available in PDF, EPUB and Kindle. Book excerpt: We present methods based on multiple-version of object codes for controlling the growth of parallelism. The key to the success of these methods is the decision when to switch from executing parallel version to executing sequential version, and vise versa. A framework is proposed for investigating this problem and for comparing performance of different control schemes. All of the schemes proposed have been implemented in the PARCEL run-time system, and the experimental results are discussed in detail.

This book was released on 2012-12-06 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been widely recognized that artificial intelligence computations offer large potential for distributed and parallel processing. Unfortunately, not much is known about designing parallel AI algorithms and efficient, easy-to-use parallel computer architectures for AI applications. The field of parallel computation and computers for AI is in its infancy, but some significant ideas have appeared and initial practical experience has become available. The purpose of this book has been to collect in one volume contributions from several leading researchers and pioneers of AI that represent a sample of these ideas and experiences. This sample does not include all schools of thought nor contributions from all leading researchers, but it covers a relatively wide variety of views and topics and in this sense can be helpful in assessing the state ofthe art. We hope that the book will serve, at least, as a pointer to more specialized literature and that it will stimulate interest in the area of parallel AI processing. It has been a great pleasure and a privilege to cooperate with all contributors to this volume. They have my warmest thanks and gratitude. Mrs. Birgitta Knapp has assisted me in the editorial task and demonstrated a great deal of skill and patience. Janusz S. Kowalik vii INTRODUCTION Artificial intelligence (AI) computer programs can be very time-consuming.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation considers several issues in the execution of Lisp programs on shared-memory multiprocessors. An overview of constructs for explicit parallelism in Lisp is first presented. An overview of constructs for explicit parallelism in Lisp is first presented. The problem of partitioning a program into process and scheduling these processes are then described, and a number of methods for performing these are proposed. These include cutting off process creation based on properties of the computation tree of the program, and basing partitioning decisions on the state of the system at runtime instead of the program. An experimental study of these methods has been performed using a simulator for parallel Lisp. This is followed by a description of the experiments that were performed and an analysis of the results. Two programs are used as illustrations-a Fast Fourier Transform, which has an abundance of parallelism, and the Cocke-Younger-Kasami parsing algorithm, for which good speedup is not as easy to obtain. The difficulty of using cutoff-based partitioning methods, and the differences between varios scheduling methods, are shown. A combination of partitioning and scheduling methods which we call dynamic partitioning is analyzed in more detail. This method is based on examining the machine's runtime state; it requires that the programmer only identify parallelism in the program, without deciding which potential parallelism is actually useful. We conclude that for programs whose computation trees have small height relative to their total size, dynamic partitioning can achieve asymptotically minimal overhead in the cost of process creation.

Download or read book Functions Objects and Parallelism written by C. K. Yuen and published by World Scientific. This book was released on 1999 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to show how programming will be changed by the concepts of parallel systems and how these concepts relate to the ideas of functions and objects. To demonstrate the kind of programming that can be done on these systems, the research language Balinda K is used. The book will also enhance the reader's grasp of the concepts of concurrency and modular programming, reviewing these from the perspectives of application programming in a parallel language. The book should interest graduate and senior undergraduate students of computer science and computer engineering, and IT professionals working in a multiprocesing or distributed computing environment.

Download or read book Parallel Lisp written by Takayasu Itō and published by Springer. This book was released on 1990 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This volume presents the proceedings of a workshop at which major Parallel Lisp activities in the US and Japan were explained. Work covered includes Multilisp and Mul-T at MIT, Qlisp at Stanford, Lucid and Parcel at Illinois, PaiLisp at Tohoku University, Multiprocessor Lisp on TOP-1 at IBM Tokyo Research, and concurrent programming in TAO. Most papers present languages and systems of Parallel Lisp and are in particular concerned with: - Language constructs of Parallel Lisp and their meanings from the standpoint of implementing Parallel Lisp systems; - Some important technical issues such as parallel garbage collection, dynamic task partitioning, futures and continuations in parallelism, automatic parallelization of Lisp programs, and the kernel concept of Parallel Lisp. Some performance results are reported that suggest practical applicability of Parallel Lisp systems in the near future. Several papers on concurrent object-oriented systems are also included."--PUBLISHER'S WEBSITE.

Download or read book An Implementation of a Parallel Processing Package in LISP written by Donald William Harney and published by . This book was released on 1976 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of a process is often used in connection with operations of parts of a computer system. This thesis discusses processes in terms of their use as representations of a physical object or system. Five primitives are introduced as operators for allowing processes to be run in a piecemeal fashion. A function package is presented which supplements UCI LISP and allows the user to define LISP functions as processes which (conceptually) run in parallel. The process functions are presented as a package which supplements the LISP system. The functions SUSPEND, RESUME and TERMINATE allow the user to temporarily stop the execution of an instance, continue the execution of an instance, or destroy an instance of a process, respectively. The ACCESS function allows one instance to look up variable values local to another instance. The START function is used as a process controller and begins the execution of the processes. Two illustrations of the function package are given. The first example, a growth model of a stand of grand fir trees, has been implemented and illustrates parallel processing in a numerical simulation environment. The second example is the Lee algorithm for finding the shortest path through a directed weighted graph. This example has not been implemented, but is discussed as an example of parallel processing in a symbolic computational environment.

Book excerpt: Algorithms defined as recursive functions, such as in pure LISP, are shown to have structure sufficient to distinguish between processes which must be executed in sequence and processes which may be executed in parallel. An interpreter program is presented for executing LISP programs and simultaneously computing the number of processors needed at each step of program execution in order to achieve optimum parallel processing. Sample program runs are presented to show speed-up ratios between strictly sequential and optimally parallel executions. A possible hardware organization for a parallel processing system derived from the interpreter program is presented. (Author).

Book excerpt: Parallel and distributed computing are becoming increasingly important as cost-effective ways to achieve high computational performance. Symbolic computations are notable for their use of irregular data structures and hence parallel symbolic computing has its own distinctive set of technical challenges. The papers in this book are based on presentations made at a workshop at MIT in October 1992. They present results in a wide range of areas including: speculative computation, scheduling techniques, program development tools and environments, programming languages and systems, models of concurrency and distribution, parallel computer architecture, and symbolic applications.
