Hello Steven,
if its warewulf v4 you can have a look at
https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fwarewulf%2Fwarewulf%2Fblob%2Fmain%2Fetc%2Fexamples%2Fslurm.conf.ww&data=05%7C02%7Csteven.jones%40vuw.ac.nz%7Cc5825b5aa4ce464bb94d08dd1474a3be%7Ccfe63e236951427e8683bb84dcf1d20c%7C0%7C0%7C638689213504957486%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=SYQjJKU7LC9IMd0Od0NgAA4iiQbnViS9uYZv7JHq4RQ%3D&reserved=0
which is a template for a slurm.conf created from the available nodes in warewulf.

kind regards,
Christian
