Intel Xeon Phi Coprocessor High Performance Programming

Chapter 1

Introduction

In this book, we bring together the essentials to high performance programming for a Intel® Xeon Phi™ coprocessor. As we’ll see, programming for the Intel Xeon Phi coprocessors is mostly about programming in the same way as you would for an Intel® Xeon® processor-based system, but with extra attention on exploiting lots of parallelism. This extra attention pays off for processor-based systems as well. You’ll see this “Double Advantage of Transforming-and-Tuning” to be a key aspect of why programming for the Intel Xeon Phi coprocessor is particularly rewarding and helps protect investments in programming.

The Intel Xeon Phi coprocessor is both generally programmable and tailored to tackle highly parallel problems. As such, ...
