[HTCondor-users] HAS_CVMFS_something ?

[Steffen Grunewald <steffen.grunewald@xxxxxxxxxx>]

Good morning/afternoon/...,

today, after a rather lengthy upgrade of our HTCondor pool, I found some jobs
in "idle" state, despite plenty of resources still available.

Investigation (better_analyze) shows, for one of the affected jobs:


The Requirements expression for job 27474.000 is

    ((HAS_CVMFS_singularity_opensciencegrid_org is true)) && (TARGET.Arch == "X86_64") && (TARGET.OpSys == "LINUX") && (TARGET.Disk >= RequestDisk) && (TARGET.Memory >= RequestMemory) && (TARGET.Cpus >= RequestCpus) && (TARGET.HasFileTransfer && versioncmp(split(TARGET.CondorVersion)[1],"8.9.7") >= 0) &&
    TARGET.HasSelfCheckpointTransfers

Job 27474.000 defines the following attributes:

    RequestCpus = 16
    RequestDisk = 10485760
    RequestMemory = 40000

The Requirements expression for job 27474.000 reduces to these conditions:

         Slots
Step    Matched  Condition
-----  --------  ---------
[0]           0  HAS_CVMFS_singularity_opensciencegrid_org is true
[11]        585  TARGET.HasFileTransfer
[12]        585  versioncmp(split(TARGET.CondorVersion)[1],"8.9.7") >= 0


Older jobs from the same user (and similar DAG) didn't require that HAS_CVMFS_...
to be set.

While all machines have CVMFS access, `ls /cvmfs/singularity.opensciencegrid.org`
works on all pool nodes, this (never seen before) requirement needs to be fulfilled
- but I have no idea whether this has to be done via setting that HAS_CVMFS_... via
a configuration file (any suggestion is welcome) or whether HTCondor could take
care of it itself (perhaps triggered by another setting in the config).

I've searched the latest documentation and all of my notes, to no avail.

Is there somebody who can cure my (obvious?) blindness?

Thanks,
 Steffen
