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.

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.

This book was released on 2012-12-06 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motivation It is now possible to build powerful single-processor and multiprocessor systems and use them efficiently for data processing, which has seen an explosive ex pansion in many areas of computer science and engineering. One approach to meeting the performance requirements of the applications has been to utilize the most powerful single-processor system that is available. When such a system does not provide the performance requirements, pipelined and parallel process ing structures can be employed. The concept of parallel processing is a depar ture from sequential processing. In sequential computation one processor is in volved and performs one operation at a time. On the other hand, in parallel computation several processors cooperate to solve a problem, which reduces computing time because several operations can be carried out simultaneously. Using several processors that work together on a given computation illustrates a new paradigm in computer problem solving which is completely different from sequential processing. From the practical point of view, this provides sufficient justification to investigate the concept of parallel processing and related issues, such as parallel algorithms. Parallel processing involves utilizing several factors, such as parallel architectures, parallel algorithms, parallel programming lan guages and performance analysis, which are strongly interrelated. In general, four steps are involved in performing a computational problem in parallel. The first step is to understand the nature of computations in the specific application domain.
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 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.
Download or read book Parallel Computation and Computers for Artificial Intelligence written by J.S. Kowalik and published by Springer Science & Business Media. 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.

This book was released on 1993-11-03 with total page 438 pages. Available in PDF, EPUB and Kindle. 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.

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: * Treats LISP as a language for commercial applications, not a language for academic AI concerns. This could be considered to be a secondary text for the Lisp course that most schools teach . This would appeal to students who sat through a LISP course in college without quite getting it – so a "nostalgia" approach, as in "wow-lisp can be practical..." * Discusses the Lisp programming model and environment. Contains an introduction to the language and gives a thorough overview of all of Common Lisp’s main features. * Designed for experienced programmers no matter what languages they may be coming from and written for a modern audience—programmers who are familiar with languages like Java, Python, and Perl. * Includes several examples of working code that actually does something useful like Web programming and database access.
