<p>Concurrent C, a superset of C providing parallel programming facilities, is considered. A uniprocessor version of Concurrent C was first implemented. After experience with this version, the Concurrent C implementation was extended to run on two types of multiple processor systems: a set of computers connected by a local area network (the distributed version) and a shared-memory multiprocessor (the multiprocessor version). Experience with implementing and using these versions of Concurrent C is described. Specifically, the language changes triggered by the multiple processor implementations, some sample programs, a comparison of the execution times on various systems, and the suitability of these multiple processor architectures are discussed.</p>
