中文摘要：

针对三维多子区激光推进并行数值模拟问题，基于按子区独立进行区域分解策略，引入物理网格点负载权重，实现了负载平衡。通过提高Cache命中率、优化消息传递、并行写文件等措施，使设计实现了所研究问题的并行化。并在某国产巨型机上对不同算例进行了测试。当并行度为16时，最低加速比高于8．96，实现了采用并行计算加快激光推进机理研究的目的。

英文摘要：

As to the problem of parallel numerical simulation for laser propulsion of three dimensions and multisub domain in China, grid point weighted load is introduced, realized load balancing, based on the policy of sub domain decomposition independently, achieving parallelization of the problem analyzing, through measures of improving cache hit rate, optimizing message passing, writing in parallel files, etc. When testing different examples on one home made supercomputer, sion mechanism, on condition that than 8.96. the purpose is realized by adopting parallel when the degree of parallelism is 16, the computing to accelerate laser propulsmallest number of speedup is more
