Re: [HTCondor-users] Concurrency limit does not work on primary group

[Bob Ball <ball@xxxxxxxxx>]

I have little experience with this.  Does condor_userprio work for you?  I remember stopping Condor on the master after we had gotten rid of all bad ConcurrencyLimit settings, including in pending jobs, wiping the file /var/lib/condor/spool/Accountantnew.log (which wipes your Condor Accounting history, but, oh well, it regenerates), then restarting Condor to get around this particular issue.

All my experience on this bit was legacy though, as we had stopped trying to use Concurrency Limits before this struck us; some left-over residue was biting us.  If I remember, Concurrency Limits  did not happily play with AccountingGroup limits?

Hi Bob:

  I changed group name from 'GROUP_NONLHC' to ''GROUPNONLHC' , and after sometime 'GROUP_NONLHC' is phased out, but still concurrency limit does not work for this primary group 'GROUPNONLHC'.

From Jaime Frey, in regard to a problem we were having a few weeks back.

Concurrency limit names are expected to only contain letters, digits,
and '.'. But nothing prevents a job from asking for limits that
contain other characters. If a job does so, then the negotiator starts
tracking the limit. It also includes the limits in its response to
condor_userprio. condor_userprio will fail in the way you've observed
if any of the limits include unexpected characters.

Your underscore may be bombing this out.

Hi Gang,

Try changing the concurrency limit to:

debug(strcat(AcctGroup, “,”, AcctSubGroup, “,”, Owner))

This will dump the _expression_ evaluation information into negotiator log.

Dear Condor experts:

  Our negotiator is running condor-8.2.2-265643.x86_64, in our current configuration, we set  ConcurrencyLimits = strcat(AcctGroup, ",", AcctSubGroup, ",", Owner)

svr011:~# condor_q -global -autoformat ConcurrencyLimits | grep group_NONLHC  | tail -n 1
group_NONLHC,none,ilc023

'group_NONLHC' is the AcctGroup which is the primary group. 
'none' is the AcctSubGroup which is a subgroup in 'group_NONLHC' 
'ilc023' is a Owner in the subgroup 'none'.


Currently we have 453 ilc023 jobs running and 420 ilc jobs idle in the queue:
svr019:~# condor_ls --vo
Owner            Idle  Running  Held  Suspended Completed Removed Transferring_output
ilc023         420     453     4     0     0     0     0

 When I add a line 'ILC023_LIMIT = 400' and reconfigured the Negotiator,  in NegotiatorLog I can see:

     Rejected 183823.0 group_NONLHC.none.ilc023@xxxxxxxxxxxxxxx <10.141.255.10:60599>: concurrency limit none reached

 When I add a line 'NONE_LIMIT = 400' and reconfigured the Negotiator ,  in NegotiatorLog I can see:

     Rejected 186612.0 group_NONLHC.none.ilc023@xxxxxxxxxxxxxxx <10.141.255.10:60599>: concurrency limit none reached

  But when I add  a line 'GROUP_NONLHC = 400' and reconfigured the Negotiator ,  in NegotiatorLog I can only see:

     Rejected 79352.0 group_NONLHC.none.ilc023@xxxxxxxxxxxxxxx <10.141.255.11:46371>: no match found

  This message means the job has already passed the concurrency limit but not able to find free node. 

  Any idea why the concurrency does not work on the primary group? 

  Cheers,Gang
