Discussion

  • Leave 8.8 in upcoming because of the empty daemon list may affect central managers that also run a submit host and as an execute node
  • Marco expects to release a GlideinWMS 3.4.5 bug-fix by the end of this week

Support Update

  • AGLT2 (BrianL): They're using /tmp for their OSG_WN_TMP and HTCondor execute directories and this is causing issues since HTCondor and user jobs fight for space.
    Recommended that they move EXECUTE off of /tmp, clean /tmp periodically, and look into Docker universe jobs or cgroups.
  • GlueX (Edgar): Their GlideinWMS pool is fixed; the admin updated the cert but not the key so HTCondor couldn't obtain its necessary credentials.
  • LIGO (Edgar): Interested in using GPUs, we're looking to find opportunistic resources
  • SWT2 (BrianL): the blahp does not appear to be refreshing proxies after 24h on WNs and this has bitten ATLAS.
    Trying to determine if this is a configuration issue or a bug.
  • UFL (Carl, Derek): The Jan-Feb records have been uploaded to the GRACC but we still need to resend the records to APEL.

OSG Investigations Team

  • Derek is busy preparing for a presentation at UNL about using the OSG as a research platform
  • XRootD workshop will be held in France in 6-8 weeks
  • Some resources in topology don't have an APEL normalization factor set in topology, causing issues with APEL numbers. We have opened tickets with the relevant site admins.
