For this use case you probably want to go with Classic Fairshare
(https://slurm.schedmd.com/classic_fair_share.html) rather than
FairTree. Classic Fairshare behaves in a way similar to what you
describe. You can set up different bins for fairshare and then the user
can pull from them. So that would be my recommendation. This is how we
handle fairshare at FASRC: https://docs.rc.fas.harvard.edu/kb/fairshare/
As we use Classic Fairshare. You will need to enable this:
https://slurm.schedmd.com/slurm.conf.html#OPT_NO_FAIR_TREE as Fair Tree
is on by default.

Hi,
I’m trying to set up multifactor priority on our cluster and am having
some trouble getting it to behave the way I’d like. My main issues
seem to revolve around FairShare.
We have multiple projects on our cluster and multiple users in those
projects (and some users are in multiple projects, of course). I would
like the FairShare to be based only on the project associated with the
job; if user A and user B both submit jobs on project C, the FairShare
should be identical. However, it looks like the FairShare is based on
both the project and the user. Is there a way to get the behavior I’m
looking for?
Thanks for any help you can provide.
