摘要

本文提供了使用多线程和MPI_THREAD_MULTIPLE的高性能MPI实现的结果，该实现应用于Lattice QCD Code (CCS-QCD)，并在Oakforest-PACS机器上运行。对于较小的格子大小，性能比基线代码提高了1.8倍。

Multiple endpoints for improved MPI performance on a lattice QCD code

This paper provides results using multiple threads and a high-performance MPI implementation of MPI_THREAD_MULTIPLE applied to a Lattice QCD Code (CCS-QCD) and run on the Oakforest-PACS machine. Performance has improved from the baseline code by as much as 1.8x for smaller lattice sizes.
