Many naive parallel processing schemes were not as successful as many researchers thought, because of the heavy cost of communication and synchronization resulting from parallelization. In this paper, we identify the reasons for this poor performance and the compiler requirements for performance improvement. We realized that the parallelizing decisions should be derived from the overhead information. We added this idea to the automatic parallelizing compiler SUIF. We substituted the original backend of SUIF with our backend using MPI, and gave it the capability to validate parallelization decisions based on overhead parameters. This backend converts shared memory-based parallel programs into distributed memory-based parallel programs with MPI function calls without excessive parallelization, which causes performance degradation
