[HTCondor-users] condor_userprio hierarchical group quota

["Fischer, Max (SCC)" <max.fischer@xxxxxxx>]

Hi all,

is there any way to get condor_userprio to take into account nested groups? We use hierarchical group quotas with up to three layers, and are regularly getting confused because of this.

- By default, "Config quota" is pretty useless for us, since many groups are only used as subgroups. E.g. it shows Atlas.Pilot 0.2 and Atlas.Pilot 0.8, but hides the Atlas 0.3537 factor [1].
- Adding "-grouprollup" hierarchically shows the supergroup in "-quota" view, so one can do the calculations by hand [2]. In "-most" view, the groups appear in arbitrary order however [3].
- The "Effective Quota" and "Subtree Quota" seem to take hierarchy into account, but are in absolute slot numbers. They are confusingly wobbly when the cluster shrinks/expands

I think having "Effective Quota" and "Subtree Quota" in relative terms would help a lot, but I haven't found a knob to get this information. Is there one?

Cheers,
Max
