Patterns

Patterns have become popular recently as a way of codifying best practices for software engineering [GHJV95]. While patterns were originally applied to object-oriented software, the basic idea of patterns—identifying themes and idioms that can be codified and reused to solve specific problems in software engineering—also applies to parallel programming. In this book, we use the term parallel pattern to mean a recurring combination of task distribution and data access that solves a specific problem in parallel algorithm design.

A number of parallel patterns are described in this book. We will characterize and discuss various algorithms in terms of them. We give each pattern a specific name, which makes it much easier to succinctly ...
