So you are saying your submit files look like:
executable = foo.exe
+AccountingGroup = "something"
If so, indeed we just need to tweak the formula a bit. The startd already should be advertising the AccountingGroup of the running job in each slot, but it appends the UID_DOMAIN as well. So I suggest trying a condor_config like so :
# Set this to be how many slots each user can have on this machine
MAX_SLOTS_PER_ACCTGRP = 1
# Tell the startd to cross-advertise AccountingGroup and Activity into each
# slot, so every slot will have slot1_AccountingGroup, slot2_AccountingGroup, etc.
STARTD_SLOT_ATTRS = $(STARTD_SLOT_ATTRS) AccountingGroup Activity
# You will unfortunately need to extend this expression if you have more
# than five slots... just follow the pattern.
SLOTS_SERVING_THIS_ACCTGRP = ( \
(TARGET.AccountingGroup =?= splitUserName(slot1_AccountingGroup) && slot1_Activity == "Busy") + \
(TARGET.AccountingGroup =?= splitUserName(slot2_AccountingGroup) && slot2_Activity == "Busy") + \
(TARGET.AccountingGroup =?= splitUserName(slot3_AccountingGroup) && slot3_Activity == "Busy") + \
(TARGET.AccountingGroup =?= splitUserName(slot4_AccountingGroup) && slot4_Activity == "Busy") + \
(TARGET.AccountingGroup =?= splitUserName(slot5_AccountingGroup) && slot5_Activity == "Busy") + \
# Append to Start expression to only start jobs if this user is under
# the limit for this machine.
START = $(START) && ( $(SLOTS_SERVING_THIS_ACCTGRP) < $(MAX_SLOTS_PER_ACCTGRP) )
Hope the above helps.
