Support Update

  • CHTC (Derek, Mat): issues with authenticated access to origin-auth2001
  • OSPool (BrianL, Mat): many shadow failures due to an issue with the user job wrapper. Currently suspecting a startd cron script locking issue.
  • JLab (BrianL): JLab and their ScotsGrid site are seeing low CPU utiliziation from Slurm for CLAS12 pilots. Seems like we're requesting 8 core pilots but only advertising single core slots.
  • Hosted CEs (Carl): identified an FD file leak in the scitokens-cpp library
