Abstract

Methods are presented for the compile-time generation of synchronization instructions for parallel loops running on a multiprocessor. A synchronization instruction set and architecture are defined, and using these it is shown how to synchronize Fortran source loops so that dependences on the parallel loop are enforced. Construction of an applicable dependence graph is covered. A program transformation is given that increases the parallelism that can be utilized in a parallel loop containing nested loops. Finally, a generalizable technique is presented for reducing the number of dependences needing synchronizing in a parallel loop.
