在本文中,我们将展示,通过一个案例研究,如何采用MPI模型的分布式并行和内部共享内存并行的OpenMP并行化编译器技术,允许产生一个分层的分布式共享内存实现的算法,提出了多层次的并行性。所选择的应用程序解决了众所周知的N体问题。
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.
