I don’t have any 21.08 systems to verify with, but that’s how I remember it. Use “sshare -a -A mic” to verify. You should see both a RawShares and a NormShares column for each user. By default they’ll all have the same value, but they can be adjusted if needed.

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

       mic     ejones

       mic     frubble

Will it divide time up fairly between the users? I have:

PriorityType=priority/multifactor

PriorityFavorSmall=YES

PriorityWeightAge=50000

PriorityWeightFairshare=100000

PriorityWeightJobSize=0

PriorityWeightQOS=0

In 21.08.8.
