ABSTRACT:   With the current prevalence of multi-core processors in SMP cluster architectures, mixed-mode programming, using both MPI and OpenMP in the same application, is becoming increasingly important. In this paper we discuss three methods for the parallelization of such algorithms, namely pure MPI parallelization, fine-grain hybrid MPI/OpenMP parallelization, and coarse-grain MPI/OpenMP parallelization. We propose a new hybrid parallel programming method based on architecture hierarchy on SMP cluster. We designed a ...
