Download or read book Grain Size Management in Repetitive Task Graphas for Multiprocessor Computer Scheduling written by and published by . This book was released on 1994 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimal scheduling of parallel programs onto multiprocessor computers is an exponentially hard problem. Because of this, most scheduling algorithms in use today rely on heuristics to determine the best balance of computation and communication costs. However, because of the NP-hard nature of the problem, these heuristics have become very complex. We are concerned with a specific instance of the problem, throughput scheduling, which aims to optimize the completion rate of repetitive programs, expressed as task graphs, for which the computational and communication needs of the tasks are known in advance. We propose a simpler approach for finding better schedules, which involves testing different grain size modified versions of the task graph to find the one that results in the highest throughput for the given scheduling algorithm. Our heuristic works by alternately fusing or fissioning selected tasks of the graph then evaluating the modified task graph by measuring the expected throughput of its resultant schedule. Because of the generality of this approach, it can be applied to any scheduling algorithm that does not already include grain size modification. We test the new heuristic using a simulation of the Navy's new standard digital signal processor, the AN/UYS-2, and using various task graphs and scheduling algorithms. We show that this practical approach to scheduling can increase throughput of the Largest Process Time first algorithm by at least 16 percent for our model computer configured with four, eight, or sixteen processors.

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.

Download or read book Handbook on Synthesis Strategies for Advanced Materials written by A. K. Tyagi and published by Springer Nature. This book was released on 2022-01-04 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents state-of-the-art coverage of synthesis of advanced functional materials. Unconventional synthetic routes play an important role in the synthesis of advanced materials as many new materials are metastable and cannot be synthesized by conventional methods. This book presents various synthesis methods such as conventional solid-state method, combustion method, a range of soft chemical methods, template synthesis, molecular precursor method, microwave synthesis, sono-chemical method and high-pressure synthesis. It provides a comprehensive overview of synthesis methods and covers a variety of materials, including ceramics, films, glass, carbon-based, and metallic materials. Many techniques for processing and surface functionalization are also discussed. Several engineering aspects of materials synthesis are also included. The contents of this book are useful for researchers and professionals working in the areas of materials and chemistry.
Download or read book Readings in Distributed Artificial Intelligence written by Alan H. Bond and published by Morgan Kaufmann. This book was released on 2014-06-05 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most artificial intelligence research investigates intelligent behavior for a single agent--solving problems heuristically, understanding natural language, and so on. Distributed Artificial Intelligence (DAI) is concerned with coordinated intelligent behavior: intelligent agents coordinating their knowledge, skills, and plans to act or solve problems, working toward a single goal, or toward separate, individual goals that interact. DAI provides intellectual insights about organization, interaction, and problem solving among intelligent agents. This comprehensive collection of articles shows the breadth and depth of DAI research. The selected information is relevant to emerging DAI technologies as well as to practical problems in artificial intelligence, distributed computing systems, and human-computer interaction. "Readings in Distributed Artificial Intelligence" proposes a framework for understanding the problems and possibilities of DAI. It divides the study into three realms: the natural systems approach (emulating strategies and representations people use to coordinate their activities), the engineering/science perspective (building automated, coordinated problem solvers for specific applications), and a third, hybrid approach that is useful in analyzing and developing mixed collections of machines and human agents working together. The editors introduce the volume with an important survey of the motivations, research, and results of work in DAI. This historical and conceptual overview combines with chapter introductions to guide the reader through this fascinating field. A unique and extensive bibliography is also provided.
