摘　　要：使用多核处理器已成为构建高性能计算机系统的主流方式。结合多核高性能计算机系统集共享内存结构和分布式内存结构于一体的体系结构特点,对AREM模式开展MPI/OpenMP混合并行计算研究与实现。性能测试结果表明,使用MPI/OpenMP混合并行计算可以将并行应用扩展至更大处理机规模,缩短计算时间,不对原程序结构做大的改动、以增量方式和较小的并行化代价,取得比较好的并行计算效果。Constructing a high performance computer system based on multi-core processors has become a mainstream means.Aiming at the feature of multi-core high performance computer system architecture containing the share-memory and distributed memory structure,the research and implementation on MPI/OpenMP hybrid parallel computation of AREM model are discussed.The results of performance evaluation show that the parallel application can be scaled to more processors,and its runtime can be shortened.High parallel performance can be obtained by requiring little programming effort.The MPI/OpenMP parallel program version can be incrementally created and the cost of parallel development is acceptable.
