Intel Xeon Phi Processor High Performance Programming

Więcej o książce

This book serves as a comprehensive guide for programming the Second-Generation Intel Xeon Phi product family, known as Knights Landing. The authors combine their extensive Xeon Phi programming experience with insights from Intel Field Engineers, Application Engineers, and Technical Consulting Engineers to deliver authoritative content on programming Intel Xeon Phi products. It offers valuable information even before you start programming with an Intel Xeon Phi processor, focusing on techniques that enhance application efficiency across modern parallel computing systems, including Intel Xeon and other high-performance microprocessors. By applying these techniques, you can improve program performance on any system while preparing for Intel Xeon Phi processors. The guide covers essential programming practices, definitive insights into the Knights Landing architecture, and best practices for portable, high-performance computing. It features real-world code examples that illustrate the unique aspects of this highly parallel computational product, along with discussions on MCDRAM, AVX-512, Intel Omni-Path fabric, many-core architectures (up to 72 cores), and multi-threading (4 threads per core). Additionally, it addresses software developer tools, libraries, and programming models, including the use of Knights Landing as both a processor and a coprocessor.
