Discussion

  • Nightly/developer VMU tests are functional again after issues with the CHTC pool last week
  • AI (BrianL): We decided to add epel-testing to our nightlies to catch potential issues with EPEL updates before they're released

Support Update

  • CyVerse (Carl, Mat): upgrade issues were resolved by setting Yum priorities for HTCondor's repositories so that they're better than the OSG repositories. Upstream ticket has been made so that this becomes standard.
  • PIC/CIEMAT (BrianL): Job route order in 8.8/8.9 is hash table order instead of config order. Tested a fix for stable from the HTCondor team
  • University of Washington (BrianL): Discussed rejoining as an OSG site via Hosted CE. They need to sort outgoing network access on the WNs first.
