Composition of concurrent programs

A model and a notation are developed for specifying the composition of concurrent programs. The work is based on the observation that the composition of concurrent programs often requires not only intraprocessor coordination but also interprocessor coordination. A notation is developed for explicitly specifying both forms of coordination within a single uniform framework. Much prior work has either ignored the interprocessor coordination aspects of composition, or treated it in a manner separate from the intraprocessor coordination aspects
