  • XRootD Validation document is in "Draft" (Will go out this week)
  • (No-progress) CVMFS Singularity Sync is going to start using singularity to create the containers. Working on testing, see github discussion:
  • StashCP Go implementation, may want some help with "evaluating" it as a replacement for stashcp.
    • We have a prototype, who would like to play with it?
  • Proactive site monitoring is progressing nicely. May present at operations meeting this week.
