[HTCondor-users] Quota changes for one group without(?) effect

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi all,

we have currently an issue with our dynamic group quotas (for grid jobs
via ARC CEs), which I do not understand.
From our three main users, user BAZ got/occupied suddenly about half of
our slots while having a significant nominal smaller share than users
FOO and BAR.
To curb BAZ's enthusiam, we changed for testing the dynamic quotas on
the negotiator to
  GROUP_QUOTA_DYNAMIC_group_FOO = 0.933
  GROUP_QUOTA_DYNAMIC_group_BAR = 0.938
  GROUP_QUOTA_DYNAMIC_group_BAZ = 0.01
  ...
  GROUP_QUOTA_DYNAMIC_group_OTHER = 0.01

without much of an effect.

One difference between the users is, that BAZ runs only single slot
jobs, FOO somewhat 1:1 single and 8slot jobs (so slot rate 1:8) and BAR
only 8slot jobs - so one idea might be, that the single- vs. multi-core
use pattern somehow distorts the share distribution (but than it worked
fine before for the ratio between FOO and BAR)

As far as I see, the ifthenelse nesting of the X509 DNs into the group
names should be OK [1] (at least the brackets match). Also BAZ DN should
match and if not should be covered by the OTHERS group as well.

So, I wonder, why BAZ still gets ~50% of the slots? Maybe somebody has
an idea for me?

Cheers and thanks,
  Thomas
