NVIDIA Fellow David Kirk and UIUC Professor Wen-mei Hwu have published their landmark textbook, Programming Massively Parallel Processors: A Hands-on Approach. This book will enable generations of programmers to understand and exploit the massively parallel architecture of GPUs. Various techniques for constructing parallel programs are explored in detail. The book also uses case studies to demonstrate the development process, which begins with computational thinking and ends with effective and efficient parallel programs. If you are looking to acquire a solid foundation in massively parallel development, this is an excellent place to start.
The book can be found at Amazon (http://is.gd/7bNYP) as well as many other bookstores.
