Ebook: How to Write Parallel Programs: A First Course

In the not-too-distant future every programmer, software engineer, and computer scientist will need to understand parallelism, a powerful and proven way to run programs fast. The authors of this straightforward tutorial explain why this is so and provide the instruction that will transform ordinary programmers into parallel programmers. How to Write Parallel Programs focuses on programming techniques for the largest class of parallel machines - general purpose asynchronous or MIMD machines. It outlines the basic parallel algorithm classes and the three basic programming paradigms, takes up the implementation techniques for these paradigms, and presents a series of case studies explaining code and discussing its measured performance. Because parallel programming requires both a computing language and a coordination language, the authors use C and Linda (a language they developed) as a combination that can be simply and efficiently implemented on a wide range of machines. The techniques discussed, however, can be applied in any comparable language environment. Contents: Introduction. The Three Basic Models of Parallelism.
