Discussion

  • Edgar had a meeting with the LIGO folks last week:
    • Sites accidentally got both HTCondor-CE from the CHTC Yum repositories. As we move all of the OSG specifics to the OSG CE metapackage, this should be a reasonable installation setup.
    • LIGO depends on Edgar's RSV probe but we no longer support RSV. They need an alternative solution for 3.5.
    • They're interested in another training, similar to the one Edgar/Christina gave them a few years ago, in Wisconsin somewhere. Unfortunately, the week they're planning on meeting is during the OSG All Hands.
  • AI (BrianL): Create GlideinWMS 3.6.1 ticket

OSG Investigations Team

  • Working with Brian (and Frank?) on GRACC changes.
    • Higher priority this week, need to get it done.
  • Update of GRACC ES, which may require some development changes. Hopefully updating... this week?
  • DONE NSF science bucket metadata for GRACC development.
    • DONE Need to discuss with the RCF team about field of science updates
    • DONE Add science bucket on a dashboard (on payload screen, but can be added to more)
  • Development of scitokens-cpp for WLCG compatibility and testing framework. Expect a new release in ~week or so.
  • Simple validation of xrootd-monitoring-collector passed.
    • Data collected for production validation, now to correlate the 2 sources, collector and remote xrootd server. Difficult step.
  • Development on perfsonar tape-backup flow with John.
  • XRootD development for TCP stats.
