| 摘 要： | OpenMP(Open Multi-Processing)能够在共享存储环境中获得理想的并行性能,MPI＋OpenMP混合并行编程模型更贴近于多核心集群的体系结构。在多核心集群上进行实验,混合模型相对串行程序可缩短95%的运算时间,加速比超过20。实验结果表明,该混合模型比纯MPI并行的系统具有更优的加速比和扩展性,是对纯MPI并行系统的一种改进。

| Abstract: | OpenMP(Open Multi-Processing)can achieve an ideal parallel performance on shared storage system. MPI+OpenMP hybrid parallel programming model is closer to the architecture of multi-core clusters. The hybrid model on the multi-core cluster was executed. The test results showed that the hybrid parallel programming model could reduce 95% of the run time of the serial program. And its parallel speed-up ratio was more than 20. This paper shows the hybrid parallel model is an improvement of the pure MPI parallel system with better speed-up ratio and scalability. |
