ParC - An Extension of C for Shared Memory Parallel Processing

this paper we describe the features and semantics of ParC. The rest of this section explains the motivation for designing a new language, the effect of the motivating forces on the design, and the structure of the software environment that surrounds it. The next section describes the parallel constructs and scoping rules. The exact semantics of parallel constructs when there are more activities than processors have been widely neglected in the literature. We discuss this issue and provide guidelines for acceptable implementations. We then describe the innovative instructions for forced termination, which are based on analogies with C instructions that break out of a construct, followed by a discussion of synchronization mechanisms. A discussion of the programming methodology of ParC is then given and is followed by a discussion of our experiences with ParC . A comparison of ParC with other parallel programming languages is delayed until the end of the paper, after we have described all of its features
