ICU-PFC: an automatic parallelizing compiler

We introduce ICU-PFC: an automatic parallelizing compiler. It receives FORTRAN source code and generates parallel FORTRAN code where OpenMP directives for parallel execution are inserted. A research compiler is developed to test automatic parallelizing techniques in the SMP environment. ICU-PFC detects DO ALL parallel loops and inserts appropriate OpenMP directives. For parallel loop detection, we designed and implemented a dependence matrix which is used for storing data dependence information of statements in a loop. In experimental results ICCT-PFC generated code showed better performance than sequential code and even manually parallelized code.
