I've read the manual and I re-read the other link. What they boil down to is
Fair Share is calculated based on a recondite "rooted plane tree", which I do
not have the background in discrete math to understand.
I'm hoping someone can explain it so my little kernel can understand.

Subject: [slurm-users] FairShare
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
