Hi Slurm users,
We have found the need to execute a parallel command on all nodes
running jobs belonging to a particular user.
I have made a configuration to the excellent ClusterShell tool as
documented in https://wiki.fysik.dtu.dk/niflheim/SLURM#clustershell
If you add a "slurmuser" section to the
/etc/clustershell/groups.conf.d/slurm.conf file, you can now run
commands such as:
$ clush -bw@su:username 'df -Ph /scratch'
$ clush -bw@su:username 'du -s /scratch/username'
I hope that others may find this feature useful.
/Ole
