Constructive Methods for Parallel Programming

The information age technology revolution promises enormous benefits to the U.S. and global economies. Yet if those benefits are to be fully realized, policymakers in the U.S. and abroad must rethink some fundamental premises about how economic activity has traditionally been governed. Should we continue to regulate industries the way we have in the past? Does the digital age require a new approach to antitrust enforcement? To best facilitate global electronic commerce, what changes are needed in intellectual property law, professional licensing requirements, laws governing privacy and content, and policies relating to standards? And what steps, if any, are required to best ensure that all citizens have access to the new technologies? This book examines these and other policy issues. It draws on a spring 1997 conference sponsored by the Brookings Institution and the Cato Institute where leading experts in various fields related to information technology presented their views.

A guide to the most recent, advanced features of the widely used OpenMP parallel programming model, with coverage of major features in OpenMP 4.5. This book offers an up-to-date, practical tutorial on advanced features in the widely used OpenMP parallel programming model. Building on the previous volume, Using OpenMP: Portable Shared Memory Parallel Programming (MIT Press), this book goes beyond the fundamentals to focus on what has been changed and added to OpenMP since the 2.5 specifications. It emphasizes four major and advanced areas: thread affinity (keeping threads close to their data), accelerators (special hardware to speed up certain operations), tasking (to parallelize algorithms with a less regular execution flow), and SIMD (hardware assisted operations on vectors). As in the earlier volume, the focus is on practical usage, with major new features primarily introduced by example. Examples are restricted to C and C++, but are straightforward enough to be understood by Fortran programmers. After a brief recap of OpenMP 2.5, the book reviews enhancements introduced since 2.5. It then discusses in detail tasking, a major functionality enhancement; Non-Uniform Memory Access (NUMA) architectures, supported by OpenMP; SIMD, or Single Instruction Multiple Data; heterogeneous systems, a new parallel programming model to offload computation to accelerators; and the expected further development of OpenMP.

Computer umgeben uns heute in fast allen Lebensbereichen. Sie erleichtern uns nicht nur als PC oder Laptop die Arbeit, sondern sind auch eingebettet in zahlreiche Objekte unseres taglichen Lebens - vom Auto bis zur Waschmaschine. Doch wie funktionieren moderne Rechner eigentlich? Und wie werden diese hochkomplexen, aus Milliarden Komponenten bestehenden Gerate entworfen? Das Buch erklart auf verstandliche, informative und unterhaltsame Weise den Aufbau und die Funktionsweise heutiger Computersysteme. Einzelne inhaltliche Abschnitte werden durch Links zu Videos erganzt, in denen Professor Rolf Drechsler relevante Themen pragnant und pointiert vorstellt.

Carefully detailed screenshots and step-by-step directions illustrate how to use Sony's new consumer-level video and audio editing applications, in a concise, time-efficient way. Readers learn the rudiments of navigating Vegas Movie Studio and the companion audio applications, Sound Forge Audio Studio and ACID Music Studio, to perform a complete range of tasks, from editing video and audio, to compositing and outputting their final project. This is the eighth book in the new VASST Instant Series produced in cooperation with the Sundance Media Group.

Computing Essentials offers a unique, visual orientation that gives students a basic understanding of computing concepts. Computing Essentials is one of the few books on the market that is written by a professor who still teaches the course every semester and loves it. While combining current topics and technology into a highly illustrated design geared to catch students' interest and motivate them, this text provides an accurate snapshot of computing today. When bundled with software application lab manuals, students are given a complete representation of the fundamental issues surrounding the personal computing environment.
