• Presentation plus discussion

Slides AnalysisWG.pdf AnalysisWG.ppt

17 Goals & Metrics for Data Taking Readiness "Challenge"

• Service validation if software is changed/upgraded
• Specific tests (e.g. throughput) to ensure that no problems have been introduced
• Tests of functions not yet tested (e.g. Reprocessing/data recall at Tier 1s)

• “Simulated” downtime of 1-3 Tier1s for up to – or exceeding – 5 days (window?) to understand how system handles export including recall from tape
• Scheduled(?) recovery from power-outages
• Extensive concurrent batch load – do shares match expectations?
• Extensive overlapping “functional blocks” – concurrent production & analysis activities
• Reprocessing and analysis use cases (Tier1 & Tier2) and conditions "DB" load - validation of current deployment(s)
• Tape rates - can sites support concurrent tape rates needed by all VOs it supports concurrently?

• Oracle 11g release 2

24 2009 WLCG Collaboration and Review workshops - proposals

• dCache Tier-1 workshop on January 14th and 15th in FZK (Jos)
• WLCG Collaboration workshop, 21-22 March, Prague (agenda).
• Review workshop prior to EGEE'09 in Barcelona
• Review workshop co-located with OGF 27
• Potential workshop covering Asia-Pacific region

• Future / further workshops at CERN??? If yes, when?? where??
  • IT amphitheatre probably too small - other possibilities 50%, 100%, 200% bigger...
