Communicating Sequential Processes

Abstract

This paper suggests that input and output are basic primitives of programming and that parallel composition of communicating sequential processes is a fundamental program structuring method. When combined with a development of Dijkstra's guarded command, these concepts are surprisingly versatile. Their use is illustrated by sample solutions of a variety of familiar programming exercises. © 1983, ACM. All rights reserved. © 1983, ACM. All rights reserved.
