Update on ACE- 2


Ace gridview comparison

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


Oring of ces standard gv algorithm

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 - 5


Ace next steps

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


Conclusion

Conclusion

ACE ready for OPS based on any CE flavour

Update on ACE - 7


Miscellaneous

Miscellaneous

  • Delayed metric results

    • We would like to set ‘max delay’.

  • Replacement of CA probe

    • 'org.sam.WN-CAver' by new probe 'hr.srce.CADist-Check’

    • Tentative date: 01st August
