| 摘 要： | 详细描述了适用于SMP集群这种多层次并行体系结构的混合并行编程模型MPI／OpenMP，它提供了实现SMP节点间和节点内多层次并行的机制。在此基础上结合实用的性能评价方法，分别介绍了MPI，OpenMP和单处理器三个层次上的一些常用和有效的并行优化技术，并指出单处理器性能优化是提高并行程序性能一个不容忽视的问题。

| Abstract: | This paper describes the hybrid parallel programming model MPI/OpenMP which is suitable for the hierarchical architecture of SMP cluster in detail, It also provides the inter-and intro-node hierarchical parallelism. Then combined with an available performance evaluation method, a number of effective parallelization and optimization techniques on the MPI, OpenMP and single-processor three levels are introduced respectively, Meanwhile, we emphasize that performance optimization on single-processor is an important issue which cannot be ignored for improving parallel program performance. |
