Performance analysis of Hybrid OpenMP/MPI N-Body application

Aversa, R; Martino, B Di; Mazzocca, N; Venticinque, Salvatore
Abstract:
In this paper we show, through a case-study, how the adoption of the MPI model for the distributed parallelism and OpenMP parallelizing compiler technology for the inner shared memory parallelism, allows to yield a hierarchically distributed-shared memory implementation of an algorithm presenting multiple levels of parallelism. The chosen application solves the well known N-body problem.
