Intel® Xeon Phi(TM) Coprocessor Architecture and Tools: The Guide for Application Developers
provides developers a comprehensive introduction and in-depth look at the Intel Xeon Phi
coprocessor architecture and the corresponding parallel data structure tools and algorithms
used in the various technical computing applications for which it is suitable. It also examines
the source code-level optimizations that can be performed to exploit the powerful features of
the processor. Xeon Phi is at the heart of world's fastest commercial supercomputer which
thanks to the massively parallel computing capabilities of Intel Xeon Phi processors coupled
with Xeon Phi coprocessors attained 33.86 teraflops of benchmark performance in 2013.
Extracting such stellar performance in real-world applications requires a sophisticated
understanding of the complex interaction among hardware components Xeon Phi cores and the
applications running on them. In this book Rezaur Rahman anIntel leader in the development of
the Xeon Phi coprocessor and the optimization of its applications presents and details all the
features of Xeon Phi core design that are relevant to the practice of application developers
such as its vector units hardware multithreading cache hierarchy and host-to-coprocessor
communication channels. Building on this foundation he shows developers how to solve
real-world technical computing problems by selecting deploying and optimizing the available
algorithms and data structure alternatives matching Xeon Phi's hardware characteristics. From
Rahman's practical descriptions and extensive code examples the reader will gain a working
knowledge of the Xeon Phi vector instruction set and the Xeon Phi microarchitecture whereby
cores execute 512-bit instruction streams in parallel.
