Discussion

  • AI (Marian): Add BrianL and Andy to discussion about CMS monitoring configuration
  • AI (Diego): Send BrianL local UCSD XRootD standalone and redirector configurations
  • AI (BrianL): Verify non-UW Software Team access to the new OSG Software testing host

Support Update

  • Caltech, Nebraska (Mat): issue with missing GridFTP logs; we have a package that addresses this issue
  • Notre Dame (Edgar): pilots landing on GPU nodes but not able to use the GPUs; we suspect that it's a wrapper script issue
  • Purdue (Diego): saw 5-6 different issues and saw that the first two accounted for 70% of the errors. The next build of XRootD should solve the first issue and they are increasing the # of TCP connections to address the second.
