ACE & GridView comparison (OPS) For the standard and official algorithm: • Differences for daily availabilities for ~15 sites • Some bugs were detected • 11 tickets already fixed • 6 remaining tickets to be fixed by mid April • Also, topology info was missing/wrong in GOCDB • 4 GGUS tickets opened to sites • Please ensure that services are declared in GOCDB • Arc-CE tests are different in Nagios and SAM • In contact with the responsibles for ARC submissions 3

  4. ACE Plan • By mid April • Issues identified should have been solved • Beginning of May • Generate the reports considering the last 2 weeks of April • Present comparison of reports: • GridView vs ACE standard algorithm • Standard vs the two ACE algorithms including CREAM 4
