OSG Investigations Team

  • Update of GRACC ES, which may require some development changes. GRACC ES update is still ongoing.
    • Wait for Marian to update.
  • Github actions are cool.
    • Modifying scitokens-cpp build process to use github actions. Possibly applicable for others. Reusable components!
  • (Derek) scitokens-cpp update - Make release.
  • (overdue) 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.
  • (in progress) Development on perfsonar tape-backup flow with John.
    • Working with UChicago
  • (in progress) XRootD development for TCP stats.

Discussion

Derek will give a short presentation on GitHub actions after next week's meeting
