[slurm-users] Re: Create filenames based on slurm hosts

I am working on power logging of a GPU cluster I am working with. I am running jobs on multiple hosts. I wanst to create a file , one for each host, which has a unique filename containing the host name. Something like clush -w $SLURM_JOB_NODELIST "touch file$(hostname)"

Doing

clush -w $SLURM_JOB_NODELIST "touch file$(hostname)"

will expand $(hostname) on the host where you run clush as the double quotes do not stop the local shell from expanding. Try single quotes instead, like

clush -w $SLURM_JOB_NODELIST 'touch file$(hostname)'
