Summary

OpenCL in Action

is a thorough, hands-on presentation of OpenCL, with an eye toward showing
developers how to build high-performance applications of their own. It begins
by presenting the core concepts behind OpenCL, including vector computing,
parallel programming, and multi-threaded operations, and then guides you step-
by-step from simple data structures to complex functions.

About the Technology

Whatever system you have, it probably has more raw processing power than
you're using. OpenCL is a high-performance programming language that maximizes
computational power by executing on CPUs, graphics processors, and other
number-crunching devices. It's perfect for speed-sensitive tasks like vector
computing, matrix operations, and graphics acceleration.

About this Book

OpenCL in Action

blends the theory of parallel computing with the practical reality of building
high-performance applications using OpenCL. It first guides you through the
fundamental data structures in an intuitive manner. Then, it explains
techniques for high-speed sorting, image processing, matrix operations, and
fast Fourier transform. The book concludes with a deep look at the all-
important subject of graphics acceleration. Numerous challenging examples give
you different ways to experiment with working code.

A background in C or C++ is helpful, but no prior exposure to OpenCL is
needed.
