摘要

我们首先介绍了两种常见MPI实现的多核特定优化模块“MPICH2”和“Open MPI”，然后在一台多核计算机上测试了它们的性能。通过启用和禁用这些模块，我们提供了它们在不同环境下的性能，包括带宽和延迟。最后，我们分析了两种MPI实现，并讨论了MPI实现的选择和可能的改进。

An Analysis of Multicore Specific Optimization in MPI Implementations

We first introduced the multicore specific optimization modules of two common MPI implementations â" MPICH2 and Open MPI, and then tested their performance on one multicore computer. By enabling and disabling these modules, we provided their performance, including bandwidth and latency, under different circumstances. Finally, we analyzed the two MPI implementations and discussed the choice of MPI implementations and possible improvements.
