OSG Investigations Team

Largely the same as last week

  • Autoatmated 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.
  • HTCondor-TCP stats packaging for the submit nodes (SchedDs)
  • StashCP udpates, run from everywhere!
