Micheal,
Details are at https://slurm.schedmd.com/fair_tree.html
<https://slurm.schedmd.com/fair_tree.html>. If they have the same shares
and usage as each other, they will have the same fair share value. One
thing to keep in mind is that sshare rounds or truncates the values, so
0.000000 does not necessarily mean that a value is actually 0.
https://slurm.schedmd.com/SUG14/fair_tree.pdf has more details, starting
at page 34 or so.

Can someone tell me how to calculate fairshare (under fairtree)? I can't figure
it out. I would have thought it would be the same score for all users in an
account. E.g., here is one of my accounts:
Account User RawShares NormShares RawUsage NormUsage EffectvUsage
LevelFS FairShare
