基于SMP机群的层次化并行编程技术的研究

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 lhat 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.
