OpenCL in Action: How to accelerate graphics and computations

by Matthew Scarpino

SummaryOpenCL 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 TechnologyWhatever 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 BookOpenCL 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. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.

really, between 3 & 4, about 3.6-3.7...
Book provides introduction into OpenCL, basic concepts, structures, functions, etc. But some topics aren't covered in much details

This is a very good book. There is a problem with it, though: The canonical example of OpenCL is bitonic sort. The bitonic sort code in the book is given with almost no comment. The author gives a good explanation of the bitonic sort, but never tells which part of the algorithm corresponds to what block in the code..
I havent read the last chapter on combining OpenCl and OpenGL, which seems to be very interesting..

By reading this book, I got a lot of insights on the internal architecture of modern GPU's.
