The patterns & practices group is writing a new guide that will introduce Visual C++ programmers to patterns for including parallelism in their applications. Examples of these patterns are parallel loops, parallel tasks and data aggregation with map-reduce. Each pattern has its own chapter. Each chapter includes a description of the problem, an example of where the pattern is applicable, and code that implements the solution. On this site you will find; a preliminary draft of the book, the accompanying code samples and answers to the end of chapter questions.
