New repo-update-cadist will be installed on repo-itb; Tim T needs access to that host to test scenario where there are no MD5 sums.

OSG Investigations Team

What is StashCache & XCache? StashCache is a special configuration of XCache, which is a special configuration of XRootD.

  • Automated authfile generation for Origins is upcoming.
  • Developed load testing for stashcache using Locust. Follow up with I2
  • Re-organize caches behind redirectors to split load with I2 caches. Nebraska and KC cache first. Need to register the redirector with the cache discovery methods.
  • Perfsonar mesh for the StashCache nodes, or at least nearby nodes.

Done Last Week: - HTCondor-TCP stats packaging for the submit nodes (SchedDs) - StashCP udpates, run from everywhere!
