Re: [HTCondor-users] Enforcing the policy of one job per user on a specific resource

Hi Todd,

Thank you very much, that recipe works great. I appreciate your help.

If you happen to have a moment could you provide a hint as to what would need to be changed in the start expression to achieve similar behavior for partionable slots?

Thanks again

    Hi Boris,
    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
          # 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.
           (TARGET.AccountingGroup =?= splitUserName(slot1_AccountingGroup)[0] && slot1_Activity == "Busy") + \
           (TARGET.AccountingGroup =?= splitUserName(slot2_AccountingGroup)[0] && slot2_Activity == "Busy") + \
           (TARGET.AccountingGroup =?= splitUserName(slot3_AccountingGroup)[0] && slot3_Activity == "Busy") + \
           (TARGET.AccountingGroup =?= splitUserName(slot4_AccountingGroup)[0] && slot4_Activity == "Busy") + \
           (TARGET.AccountingGroup =?= splitUserName(slot5_AccountingGroup)[0] && slot5_Activity == "Busy") + \
           0 )
          # Append to Start expression to only start jobs if this user is under 
          # the limit for this machine.
    Hope the above helps.
