Abstract :
The microprocessor industry is undergoing a dramatic change to shift from the traditional superscalar microprocessor designs to multicores. While this presents some new opportunities, it also presents new challenges to harness the power of the multicore processors. In this paper, we address this issue by investigating the performance and memory usage of the hybrid MPI + OpenMP programming models. The experimental results demonstrate great advantages of using the hybrid programming model over the popular pure MPI model in terms of both performance and memory usage.
