Re: [slurm-users] Defining an empty partition

This is reviving a very old thread but for me at least it is still the top 2 hits in google for "define empty slurm partition" so it might help someone: The solution here (of defining NodeName=nonesuch) is a bit of red-herring. I don't know why I never tried this at the time but you can do: Parti

Re: [slurm-users] Defining an empty partition

Having tried just not even defining any partitions you hit this this check which seems to ensure you can't create a cluster with no nodes. Is it possible to create a control node without any compute nodes, e.g. as part of a s

[slurm-users] Defining an empty partition

Hi all, According to the relevant manpage it's possible to define an empty partition using "Nodes= ". However this doesn't seem to work (slurm 20.2.05): [centos@testohpc-login-0 ~]$ grep -n Partition /etc/slurm/slurm.conf 72:Prior
