Yes, there is 'root' and 'mic', and everyone is under 'mic. No, I don't know any Steve. So what you're saying is I *must* at account-creation time explicitly assign a fairshare value? Would it be sufficient to just say, in my account creation script, sacctmgr modify user $NEWUSERNAME set fairsh

And now, a few hours later - with no changes made - everyone has the same fairshare? $ sshare -l -a AccountUser RawShares NormSharesRawUsage NormUsage EffectvUsage FairShareGrpTRESMins TRESRunMins

[slurm-users] Re: FairShare if there's only one account?

Hmm, no. That solved the problem of everyone having the same FairShare, but even after restarting slurmd and doing reconfigure, if I submit a job as someone with a huge usage and someone with zero usage, they both end up with the same Priority. On Aug 10, 2024, at 8:05 AM, Daniel M. Drucker

I just set PriorityFlags=NO_FAIR_TREE and this seems to have solved the problem! On Aug 10, 2024, at 7:45 AM, Drucker, Daniel wrote: According to https://docs.rc.fas.harvard.edu/kb/fairshare/ and https://slurm.schedmd.com/SUG14/fair_tree.pdf : "The Fairshare score is calculated using the

According to https://docs.rc.fas.harvard.edu/kb/fairshare/ and https://slurm.schedmd.com/SUG14/fair_tree.pdf : "The Fairshare score is calculated using the following formula.f = 2^(-EffectvUsage/NormShares)" This is clearly not happening on my system: AccountUser RawShar

[slurm-users] Re: FairShare if there's only one account?

Here is what is confusing me I guess. Look at the below. You can see that some people have no usage and some people have a lot of usage. But their FairShare value is all identical. https://lists.schedmd.com/mailman3/hyperkitty/list/slurm-users@lists.schedmd.com/thread/I53OEJSNBT2BMXYVFEFHQQKKAHI

[slurm-users] Re: FairShare if there's only one account?

So I'm still getting identical priorities for every job. For example in: squeue --format="%.18i %.9P %.50j %.8u %.8T %.10M %.9l %.6D %R %.10Q" the PRIORITY field is 98387 (which is 1* the fairshare value shown in "sshare -a -A mic") for every single job, even though some of the jobs in the

[slurm-users] Re: FairShare if there's only one account?

I got the opposite result. When I submitted a job as bsmith, they got a lower priority (the number was smaller) than the job submitted as csmith. bsmith (who has never submitted a job before) got a priority of 98387 (which is 1 times the 0.983871 FairShare), whereas csmith (who is already ru

Simple question: Does FairShare still work if every user is under one account? E.g.: $ sacctmgr show assoc format=Account,User Account User -- -- root root root mic mic asmith mic bsmith mic csmith mic djones
