摘要
基于消息传递并行程序设计平台MPI ,结合当前微处理器的高性能特征 ,探讨了二维分子动力学数值模拟程序的优化和并行 ,且具体应用到高速碰撞物理模型问题。其中 ,串行优化的性能提高了两倍 ,并行效率在由 8台高性能微机构成的微机机群上 ,均大于 90 %。
On the basis of the message passing parallel programming platform MPI,and with the high performance characteristics of contemporary microprocessors,it describes the parallelization and optimization for a two dimensional molecular dynamics code(MDP) to simulate the high speed collision physical model problems.The serial optimization has shown to be of double performance improvements,and the parallel efficiencies being above 90% under the cluster consisted of 8 Pentium\|Ⅱ microprocessors.
