Parallel programs perform several tasks simultaneously, improving performance, scalability, and responsiveness By writing parallel programs, your projects can take complete advantage of the latent power that multi-core and multi-processor computers have to offer This book shows you how to get things done I focus on the practice, rather than the theory and show you how the technology works using complete code examples to illustrate my points Each chapter not only explains the principals of parallel programming but also contains a list of common pitfalls together with details of how to recognize them, and the steps you can take to prevent them happening to you This book is an invaluable companion when tackling a wide range of parallel programming features and techniques including:
