[slurm-users] Getting nodes in a partition

[Marcus Wagner]

Hi Mahmood,

slurm comes with hostlist extraction:

[mahmood at rocks7 ~]$ scontrol show hostnames $(scontrol show partition MYPART | grep -w Nodes | cut -d '=' -f 2)


This would then be

compute-0-4
compute-0-5
compute-0-6


Best
Marcus
