并行应用程序中一些实用并行优化技术

摘要

This paper accomplishes the parallel of an applied code(Two-Dimensional Elastic-Plastic Hydrodynamic code)in some share memory parallel multi computer(SMP),whose system support such parallel as FORTRAN DO loop structure. Combined with the high performance characteristics of parallel computer environments,It finishes parallel of the main body module of the applied code,and proposes a kind of available parallel-optimization technique to Cache.Experiment indicate that better speedup is attained.%在某个共享存储式对称多处理(SMP)并行计算机上实现了应用程序(二维弹塑性流体动力学程序)的并行化。该并行计算机系统仅支持对FORTRAN DO 循环结构的并行化。文章结合并行机的高性能特征，组织了该程序主体模块的并行化计算，同时给出解决Cache问题的一个实用并行优化技术。数据结果表明：有比较好的加速比。
