Hello,
I'm trying to understand behavior of fairshare factor. I set a munin
monitoring for several accounts and observe the changes in time, and
they're not clear for me.
A background:
My users are split into two groups: sfglab and faculty,
in sfglab every one are equal, and in faculty they are additionally
split into project accounts i which they they are also equal.
for example:
root
sfglab
sfglab_user_1
sfglab_user_2
...
faculty
project_1
faculty_user_1
faculty_user_2
project_2
faculty_user_1
faculty_user_3
...
I do have 2 particularly active users that run a large jobs in sfglab,
and activity of faculty users is very variable. From very active to dead
souls.
Now this is fairshare factor for last week:

What I would expect there should be rather smooth changes instead of
those high point changes.
I would also expect to see some small constant changes from
PriorityDecayHalfLife, which is set for two weeks and recalculated every
5 minutes.
It would be great if someone could comment on that, before my users will
start comply on low priority of their jobs.
Here is my Priority config.
PriorityParameters = (null)
PrioritySiteFactorParameters = (null)
PrioritySiteFactorPlugin = (null)
PriorityDecayHalfLife = 14-00:00:00
PriorityCalcPeriod = 00:05:00
PriorityFavorSmall = No
PriorityFlags =
PriorityMaxAge = 7-00:00:00
PriorityUsageResetPeriod = NONE
PriorityType = priority/multifactor
PriorityWeightAge = 100000
PriorityWeightAssoc = 0
PriorityWeightFairShare = 200000
PriorityWeightJobSize = 0
PriorityWeightPartition = 0
PriorityWeightQOS = 0
PriorityWeightTRES = (null)
