PMAC: an environment for parallel programming

In this paper, we present a parallel programming envi- ronment called PMACS. The central structure of this environment is the Parametrized Dependence Graph that gives a very precise representation of dependen- cies. It also facilitates the recompilation of dependen- cies whenever the user is requested to introduce infor- mation about the program. A unique framework for the interprocedural constant propagation and the interpro- cedural side-effect analysis, based on symbolic evalua- tion, is used. A powerful tool for displaying graphs has also been carried out. It allows the user to understand the detected inherent parallelism of his program. A first release of PMACS written in C is already imple- mented.
