Towards the Translation of OpenMP to Hybrid MPI/OpenMP

Though it is possible to use pure OpenMP or pure MPI to develop parallel and distributed memory applications respectively, both are often combined in a hybrid MPI/OpenMP model to target clusters of multi-core nodes.In this paper, we introduce and discuss the design and implementation of a source-to-source compiler, translating OpenMP-annotated source code to MPI/OpenMP.We evaluate the performance of the translated programs on the HPC Spartan cluster at the University of Melbourne.
