摘　　要：针对多核SMP机群的体系结构特点,讨论了MPI+OpenMP混合并行程序设计技术.提出了一种多层次化混合设计新方法.设计了N-body问题的多层次化并行算法,并在曙光5000A机群上与传统的混合算法作了性能方面的比较.结果表明,该层次化混合并行算法具有更好的扩展性和加速比.For multi-core SMP cluster systems,this paper discusses hybrid parallel programming techniques based on MPI and OpenMP.We propose a new hybrid parallel programming methods that are aware of architecture hierarchy on SMP cluster systems.We design a hierarchically parallel algorithm on the N-body problem,and compared its performance with traditional hybrid parallel algorithms on the Dawning 5000A cluster.The results indicate that our hierarchically hybrid parallel algorithm has better scalability and speedup than others.
