High Performance Parallelism Pearls Volume One (eBook, ePUB)

Multicore and Many-core Programming Approaches

• Format: ePub

Produktbeschreibung

High Performance Parallelism Pearls shows how to leverage parallelism on processors and coprocessors with the same programming - illustrating the most effective ways to better tap the computational potential of systems with Intel Xeon Phi coprocessors and Intel Xeon processors or other multicore processors. The book includes examples of successful programming efforts, drawn from across industries and domains such as chemistry, engineering, and environmental science. Each chapter in this edited work includes detailed explanations of the programming techniques used, while showing high performance results on both Intel Xeon Phi coprocessors and multicore processors. Learn from dozens of new examples and case studies illustrating "success stories" demonstrating not just the features of these powerful systems, but also how to leverage parallelism across these heterogeneous systems.

• Promotes consistent standards-based programming, showing in detail how to code for high performance on multicore processors and Intel® Xeon Phi(TM)
• Examples from multiple vertical domains illustrating parallel optimizations to modernize real-world codes
• Source code available for download to facilitate further exploration

Autorenporträt

James Reinders is a senior engineer who joined Intel Corporation in 1989 and has contributed to projects including the world's first TeraFLOP supercomputer (ASCI Red), as well as compilers and architecture work for a number of Intel processors and parallel systems. James has been a driver behind the development of Intel as a major provider of software development products, and serves as their chief software evangelist. James has published numerous articles, contributed to several books and is widely interviewed on parallelism. James has managed software development groups, customer service and consulting teams, business development and marketing teams. James is sought after to keynote on parallel programming, and is the author/co-author of three books currently in print including Structured Parallel Programming, published by Morgan Kaufmann in 2012.

Rezensionen

"This book will make it much easier in general to exploit high levels of parallelism including programming optimally for the Intel Xeon Phi products. The common programming methodology between the Xeon and Xeon Phi families is good news for the entire scientific and engineering community; the same programming can realize parallel scaling and vectorization for both multicore and many-core." --from the Foreword by Sverre Jarp, CERN Openlab CTO
