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
- 个人开发机一台
- Intel(R) Xeon(R) Platinum 8260 CPU @ 2.40GHz
- 我的开发机实例只能使用 8 核 16 线程
- linux-debian9-cascadelake
- Intel(R) Xeon(R) Platinum 8260 CPU @ 2.40GHz
结果分析
log 很多，待分析补充。初步结果：
- [email protected] 费拉不堪
- [email protected] 很顶
运行脚本 run_osu.sh

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]

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
