Combining MPI and OpenMP - Vaspwiki - Vienna Ab initio …

Webcomputing. OpenMP can be combined with MPI on many such machines. Motivations for combing OpenMP and MPI are discussed. While OpenMP is typically used for exploit-ing loop-level parallelism it can also be used to enable coarse grain parallelism, potentially leading to less overhead. We show how coarse grain OpenMP parallelism can also be used WebOpenMP(OpenMulti-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。
