OSG Software Team

  • XRootD 4.10.1 was released this morning
  • Relatively few deadlines this month so we'll use our time to pay down some technical debt
    • Complete sustainable hosted CE project
    • Spin up the new OSG submit host for VMU tests
  • Next doc focus Oct 10

Discussion

  • New "unified" blahp in the upstream HTCondor punted to 8.9.5 due to build difficulties
  • AI (BrianL): Run VMU tests for GlideinWMS 3.6
  • AI (BrianL): Archive the OSG BLAH repository with pointers to the unified htcondor/BLAH fork
  • AI (Carl): Add htcondor/BLAH to the GitHub backup script
  • AI (TimT): Disable AFS/GitHub sync for htcondor/BLAH

Support Update

  • Brown (Marian): Provided some site.xml configuration that the admin needs to apply
  • Caltech (Carl): Some HDFS yum warnings upon upgrade that appear to be due to the local site configuration
  • FNAL (Mat): Gave Steve Timm a patch that hardcodes VOMS server to accept TLS > v1. We don't think we can apply this patch across the board.

OSG Investigations

  • Igor has made some progress on deploying XCaches in Azure, Amazon
  • Edgar met with Caltech folks to discuss CMS XCache usage and deployment. They decided that they will deploy k8s pods for SoCal

Discussion

Edgar mentioned some issues with the submit host setup, including that it's too OSG VO specific and that there is an HTCondor bug that requires a workaround implementation for all UC host certificates
