Coherent parallel C
E.W. Felten, Steve W. Otto · 1988
Coherent Parallel C (CPC) is an extension of C for parallelism. The extensions are not simply parallel for loops; instead, a data parallel programming model is adopted. This means that one has an entire process for each data object. An example of an “object” is one mesh point in a finite element solver. How the processes are actually distributed on a parallel machine is transparent—the user is to imagine that an entire processor in a distributed-memory environment is dedicated to each process. This simplifies programming tremendously: complex if statements associated with domain boundaries disappear; problems which do not exactly match the machine size and irregular boundaries are all handled transparently.
