[HTCondor-users] HTCondor-CE: Setting Default limits

[Stefano Dal Pra <stefano.dalpra@xxxxxxxxxxxx>]

    Hello,
    
    i'm working to configure a htcondor-ce 5.1 and have a few doubts on
    how to properly set default job limits.
    
    I'm following the examples from here:
https://htcondor.github.io/htcondor-ce/v5/configuration/writing-job-routes/
    such as this one:
JOB_ROUTER_ROUTE_Condor_Pool @=jrt
  UNIVERSE VANILLA
  # Set the requested memory to 1 GB
  default_maxMemory = 1000
@jrt

JOB_ROUTER_ROUTE_NAMES = Condor_Pool


    Q1: Is it possible to set default_maxMemory to a value proportional
    to RequestCpus of the incoming job? i.e.
    something like 
    
    default_maxMemory = $(RequestCpus:1) * 3000
    
    Q2: I applied the following defaults:
    
    JOB_ROUTER_ROUTE_t1_defaults @=jrt
    ÂÂ UNIVERSE VANILLA
    ÂÂ default_xcount = 4
    ÂÂ default_maxMemory = 4321
    ÂÂ default_maxWallTime = 61
    @jrt
    
    
    ÂBut I'm a bit confused with the overall results:
    
    0) I submit a minimal test job:
    [sdalpra@ui-htc htjobs]$ condor_submit -pool
    ce01t-htc.cr.cnaf.infn.it:9619 -remote ce01t-htc.cr.cnaf.infn.it
    ce_testp308.sub
    Submitting job(s).
    1 job(s) submitted to cluster 610.
    
    1) The job is routed
    [root@ce01t-htc ~]# condor_ce_q 610. -af routedtojobid
    8428.0
    
    2) I check classads from the routed job
    
    [root@ce01t-htc ~]# condor_q 8428.0 -af:jln jobstatus
    CpusProvisioned xcount requestcpus OriginalCpus remote_NodeNumber
    remote_SMPGranularity BatchRuntime OriginalMemory
    remote_OriginalMemory OriginalCpus remote_NodeNumber
    remote_SMPGranularity
    ID = 8428.0
    Âjobstatus = 2
    ÂCpusProvisioned = 1
    Âxcount = undefined
    Ârequestcpus = 1
    ÂOriginalCpus = 4
    Âremote_NodeNumber = 4
    Âremote_SMPGranularity = 4
    ÂBatchRuntime = 3660
    ÂOriginalMemory = 4321
    Âremote_OriginalMemory = 4321
    ÂOriginalCpus = 4
    Âremote_NodeNumber = 4
    Âremote_SMPGranularity = 4
    
    
    So this is where i'm puzzled:
    - I would expect to see xcount = 4 but it is undefined instead.
    - The running job reports CpusProvisioned = 1, and that makes me
    think that 
    remote_NodeNumber = 4, remote_SMPGranularity = 4, OriginalCpus = 4
    are somehow ignored.
    - BatchRuntime is there, with the proper value set as expected (61 *
    60) however i'm not sure on the meaning.
    The htcondor manual says: << For batch grid
    universe jobs, a limit in seconds on the jobâs
    execution time, enforced by the remote batch system.>> who is
    "remote" in this context? Does that mean that condor-ce would stop
    the running routed job after 61 minutes? Moreover,
    we have here a Vanilla universe job, at both CE and batch side:
    
    [root@ce01t-htc ~]# condor_ce_q 610. -l | grep -i univer
    JobUniverse = 5
    
    [root@ce01t-htc ~]# condor_q -l 8428.0 | grep -i univer
    JobUniverse = 5
    Remote_JobUniverse = 5
    
    Thanks for any comment
