Hi everyone, In my practice, I usually reserve a lot of nodes using `salloc` command and run tasks using `mpirun`. And now I want to do it in slurm's way. I saw in the document that I can add job steps using `srun` using `--jobid` and `--nodelist` option. However, I found that I cannot run paraview server as additional job step on existing allocated nodes. Here is the commands:
``` srun -n 56 --jobid=23456 --nodelist=cn333,cn444 pvserver --mpi --mesa --use-offscreen-rendering -sp=12345 & ``` And it will show errors saying I cannot run 56 programs listening on the same port 12345. It seems the 56 jobs are running separately. How can I diagnostic this problem further and solve it? p.s. The mpi I use is OpenMPI 1.10 and the GCC is 5.1. The HPC is tianhe-1A.
