.NET 4 Parallel Programming in C#

Adam Freeman, Author of

Normal programs perform one task at a time. 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:
