  • VO shares at CSCS
    Broadly OK
    Drop in running cores for >1 week
    And also of ATLAS share




  • Smoth ARC CE operation over the last period
  • Downtime today: Finally research now in service. Moved ARC CE dirs to the new filesystem
  • Good usage of atlas-preempt partition and cluster as a whole after increasing qos to 1200 cores for ATLAS jobs.


  • ARC CE deployment status escalated to management
  • ARC now installed and arc.conf with me for review


  • CA status
    • Procedure ongoing, but slow. QuoVadis not too reactive and gazillions of bureaucratic issues to deal with
    • Even the procedure for Unibe has not been finalised yet, the Trust Link has not been issued yet
    • Once this is done and all steps documented, all the other institutes will have to do the same
    • "High level" signature required, and several additional steps
    • In the meanwhile, we had to request 4 "emergency" certificates to the old EGI CA. Could negotiate with a EGI operation guy
