| 摘 要： | Message Passing Interface并行编程方法是目前编程人员广泛使用的方法之一，但此方法将并行性开发的任务完全交给编程人员，程序的质量与效率往往因编程人员水平及风格不同而各异，在Message Passing Interface环境下把传统串行程序转变为并行程序从而提高其性能．此外通过MPI所提供的函数来进一步优化并行程序以便提高其性能，

| Abstract: | Message Passing Interface-based parallel programming is a method which is widely used at present, but this method burdens developers with all tasks about parallelism development. It is difficult to guarantee the quality and efficiency of program because of the difference caused by programming skills and styles of different developers. The aim of this paper is to convert traditional serial program to parallel program in the MPI - based environment in order to improve the performance of program. With MPI library functions ,the performance of parallel program will be improved further. |
