osu-micro-benchmarks wu-kan

引言

无意中发现 spack 可以直接安装 osu-micro-benchmarks 了,顺手写一个脚本横向比较一下一些常见 mpi 在单机上的性能。

实验环境

结果分析

log 很多,待分析补充。初步结果:

  • openmpi@4.0.5 费拉不堪
  • mpich@3.3.2 很顶

运行脚本 run_osu.sh

#!/bin/bash
# time ./run_osu.sh > run_osu.log 2>&1

MPI_Init_thread must return MPI_THREAD_MULTIPLE!
-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[153,1],1]
  Exit code:    1

MPI_Init_thread must return MPI_THREAD_MULTIPLE!
-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[1546,1],1]
  Exit code:    1

MPI_Init_thread must return MPI_THREAD_MULTIPLE!
-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[11934,1],1]
  Exit code:    1

MPI_Init_thread must return MPI_THREAD_MULTIPLE!
-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[9554,1],0]
  Exit code:    1
