Discussion

AI (BrianL) - Follow-up with Marco about GWMS w.r.t. condor 8.9.0 security config changes

Support Update

  • AGLT2 (BrianL): high load on some worker nodes (ls /tmp hangs) with some ATLAS jobs using 100% of swap. Spent last week sorting out login issues.
  • AMNH (BrianL): Successfully set up job submission to the AMNH Slurm cluster. There's a BLAHP/Slurm issue that Suchandra had workaround hacks for that we'll need to investigate.
  • LIGO (Mat): GSI-OpenSSH hanging issue, gave them some debugging instructions.
  • Topology (Carl): Copy-paste error of downtime created some issues for our consumers. We will be adding a validation check for CreatedTime.
  • UFL (Derek): Missing January accounting records due to a Slurm update that broke our database queries. Bockjoo has a workaround that has temporarily solved this issue but we'd like to solve this more sustainably (SOFTWARE-1588).
