Abstract

A technique for extracting coarse-grained parallelism in loops is presented. It is based on splitting a set of dependence relations into two sets. The first one is to be used for generating code scanning slices while the second one permits us to insert send and receive functions to synchronize the slices execution. Codes of send and receive functions based on both OpenMP and POSIX locks functions are presented. A way of proper inserting and executing send and receive functions is demonstrated. Using agglomeration and free-scheduling are discussed for the purpose of improving program performance. Results of experiments are presented.
