Re: [HTCondor-users] Trying to understand quotas and especially hierarchical groups

[Jeff Templon <templon@xxxxxxxxx>]

Hi Thomas, 

Thanks for your mail.  I am curious why your second command generates a doubling of each group.

Itâs as you said, group_atlas usage is very close to the sum of usages of group_atlas.prod and group_atlas.anal. 

Itâs as if the groups form a hierarchy for the purpose of tracking usage, but thatâs it - in all other senses they are not hierarchical, so they are not defined as a hierarchy nor are they displayed as a hierarchy - users are displayed under their immediate subgroup if there is one, but at a level that is the same as if they were a top-level group.  There is no nesting of subgroups under the parent group, as would be expected in a true hierarchy.

Iâve pretty much decided to ditch the subgroup hierarchy, as ATLAS is the only case we have that needs it, and I can also deal with this by using a different PRIORITY_FACTOR for the pilots as for production.

The other option was to see if I could modify condor_userprio to do the right thing, I donât think I could find enough time to do that though.  But maybe someone else will chime in with the answer!
