Re: [HTCondor-users] job has all necessary slots claimed but still is idle

Hi,

I performed additional tests, tried HTCondor 8.9.11 and 9.0.1, tried different combinations of setting CLAIM_PARTITIONABLE_LEFTOVERS and CONSUMPTION_POLICY (False-True, True-False, False-False) and the problem was always there.
For some jobs schedd request and claims additional slots it won't use. If there are resources for such additional slots - the job will run, if no - the job will be IDLE forever.

Any ideas?


Best regards,
Stanislav Markevich

Subject: [HTCondor-users] job has all necessary slots claimed but still is	idle

Hi all,

My job stuck in IDLE state and I cannot understand why.


It's the only job:

    -- Schedd: parallel_schedd@xxxxxxxxxxxxxxxxxx : <10.42.0.253:45173?... @ 06/10/21 18:26:37
    OWNER     BATCH_NAME    SUBMITTED   DONE   RUN    IDLE  TOTAL JOB_IDS
    user20002 ID: 49       6/10 17:06      _      _      2      2 49.0-1

    Total for query: 2 jobs; 0 completed, 0 removed, 2 idle, 0 running, 0 held, 0 suspended 
    Total for all users: 2 jobs; 0 completed, 0 removed, 2 idle, 0 running, 0 held, 0 suspended


There are suitable slots (dynamic slots created for this job):

    Name                         OpSys State     Activity Cpus Memory
    slot1@xxxxxxxxxxxxxxxxxxxx   LINUX Unclaimed Idle     75   1544  
    slot1_1@xxxxxxxxxxxxxxxxxxxx LINUX Claimed   Idle     25   256   
    slot1@xxxxxxxxxxxxxxxxxxxx   LINUX Unclaimed Idle     0    8     
    slot1_1@xxxxxxxxxxxxxxxxxxxx LINUX Claimed   Idle     100  1792 


But "condor_q -better-analyze" says there is no successful match (and last failed match was an hour ago):

Maybe this is important, in the configuration files I have:
    CLAIM_PARTITIONABLE_LEFTOVERS = FALSE
    CONSUMPTION_POLICY = TRUE

Am I missing something? Is this a bug?


PS: after two hours of waiting I submitted another job and surprisingly both jobs ran pretty soon.
