摘要： 曙光-2000并行机系统是分布式存储系统，在此类系统上直接写并行程序是很困 难的。该文通过详细分析书写MPI程序的各种模式，结合曙光-2000并行机，给出一种将串行 程序改写成MPI并行程序的方法：分析串行程序的循环体，考虑数据依赖关系，加以适当的 M PI函数，使之并行化。

Abstract: Writing the parallel program on Dawning-2000 is difficult in that Da wning-2000 belongs to the distributed-memory system. In this paper, a method is given to transform a serial program to a parallel program by analyzing various m odules of making MPI programs and by a combination of Dawning-2000. That is, a m ethod to analyze the loop block of serial program to make it parallel throug h a consideration of data dependence and a interpolation of MPI functions.
