  1. Update on ACE Wojciech Lapka LCG MB, 7th June 2011

  2. May availability reports • ACE (“official” only for OPS): • ORing of CE flavours+ LHC experiments: • http://gridview015.cern.ch/GRIDVIEW/downloads/Reports/201105-ace/ • GridView (official for LHC experiments): • http://gridview015.cern.ch/GRIDVIEW/downloads/Reports/201105/wlcg/ Update on ACE- 2

  3. ACE/GridView comparison • ACE numbers correct since 1st of May • Minor differences • Services not declared in GOCDB • Automatic status re-computations when data received with a delay • Downtime declared for several sites • Few sites with availabilities higher in ACE for standard algorithm (to be checked) • WLCG and EGI reports fixed • Tier-2 reports (country name & description missing) Update on ACE - 3

  4. ORingof CEs & standard GV algorithm • T1 sites • Average (the same as with the old algorithm) • Availability & Reliability: 92% • FZK-LCG2: 3% higher in ACE • CE was failing while CREAM was OK • TW-LCG: 5% lower in ACE • Different SRMv2 services • General for T1s & T2s: • Lower availability for 59 sites • Higher availability for 16 sites Update on ACE - 4

  5. GridView portal based on ACE • https://gvdev.cern.ch/ACEVAL/ace_index.php • Till the time this functionality integrated in MyWLCG • Data transfers, FTS and old GridView availabilities: http://gridview.cern.ch/GRIDVIEW/ • Excel Report Generation Form • http://gvdev.cern.ch/GVPC/Excel/ACE/ Update on ACE - 5

  6. ACE - next steps • ACE still using Integration Database • Migration to Production Database • Availabilities for LHC experiments • VO feeds need improvement in ATP • Validation by the experiments Update on ACE - 6

  7. Conclusion ACE ready for OPS based on any CE flavour Update on ACE - 7

  8. Miscellaneous • Delayed metric results • We would like to set ‘max delay’. • If yes, how many days? • Replacement of CA probe • 'org.sam.WN-CAver' by new probe 'hr.srce.CADist-Check’ • Tentative date: 01st August Update on ACE - 8

  9. Questions? Update on ACE - 9

  10. Acknowledgments • GridViewTeam from BARC: • Rajesh Kalmady • Phool Chand • Vaibhav Kumar • DigamberSonvane • Pradyumna Joshi • VibhutiDuggal • Kislay Bhatt Update on ACE - 10
