我正在尝试在运行 ubuntu 16.04 的集群中安装 slurm。
我使用的是intel mpi，安装目录位于头节点/opt/intel/impi_5.01。
根据slurm指令，需要导出libpmi.so变量。https://slurm.schedmd.com/mpi_guide.html#intel_mpi
但是，我通过 ubuntu 安装了 slurm-llnl
sudo apt-get slurm-llnl
我不知道 libpmi.so 在哪里？所以我搜索了一下，在这里找到了一个文件，这是我要找的文件吗？
/usr/lib/x86_64-linux-gnu/libpmi.so
无论如何，我导出变量并尝试
srun -p old -N3 -n24 hostname
它返回，
rolly@head:~$ srun -p old -N3 -n24 hostname

看起来它正在起作用。
但当我执行任务时，
srun -p old -N3 -n24 ~/QE530-CPU/espresso-5.3.0/bin/pw.x
它产生了错误，

我相信错误提示是由于使用 intel-mpi 运行 mpiexec 造成的，应该使用 mpirun。
我该如何纠正这个问题？
谢谢！
答案1
我找到了解决方案。
1）sudo apt-get install mpich
2）srun --mpi=pmi2
3）mkl和intel相关的环境变量正确加载。
我希望这能够帮助遇到类似问题的人。
