Integration program update (Michael)

• See IntegrationProgram for Phase4 update
  • AtlasReleases
  • DQ2SiteServices
  • OSGservices
  • StorageServices
  • MonitoringServices
  • FileCatalog
  • LoadTestsP5
• Overarching near term goals, including points from the Chapel Hill meeting DistributedFacilityWorkshop2008:
  • Full and effective participation in FDR-1, FDR-2 exercises
  • Establish 200 MB/s sustained disk-to-disk throughput to all Tier2s
  • SRM v2.2 functionality now required for all ATLAS sites - implications for storage upgrades at Tier2, and bestman-xrootd development. (April 2)
  • Data placement within the US cloud to be centrally managed from BNL.
  • A technical plan for Tier3 facilities within the next three months including:
    • Deploy/test/collect experiences of PROOF at Tier3 facilities.
    • Tier3 and data access tools and best practices
• Upcoming meetings:
  • WLCG Tier-2 Workshop, April 8 2008 (Taiwan/Asian focus)
  • WLCG Collaboration Workshop (Tier0/Tier1/Tier2) - April 21-25, 2008, and following week a shortened ATLAS software workshop (April 28-30)
  • US ATLAS Tier2/Tier3, May 27-28th 2008 - location: Ann Arbor: http://indico.cern.ch/conferenceDisplay.py?confId=27666

Special topic: DQ2 0.6 upgrade (Hiro)

• Follow-up: deployment readiness - as of last week, the final version still testing, not available.

Next procecurements

• Standing agenda item, see CapacitySummary

Analysis Queue Update (Nurcan)

• TWiki page for submitting pathena jobs on the FDR Data PathenaOnFDRData.
• Follow-ups from the Jamboree week (these are listed also in the twiki page):
  • The issue with not being able to retrieve the output dataset if the same output dataset was used in an earlier unsuccessful pathena submission is solved. Tadashi implemented a protection in pathena (3/21/08).
  • Deleting user datasets made with pathena: the work already started, the implementation is in place, some tests have been done, final requirements/features to be added (Hiro and Charles).
  • Automatic redirection of analysis jobs within a cloud. Namely, no need to specify site - pathena will choose the best site based on data availability and available CPU's (needs couple of weeks to implement).
  • A survey: analysis packages used to run pathena at the analysis queues are listed here.

Operations: Production (Kaushik)

• Production summary
• Production shift report

Operations: DDM (Hiro)

• Follow-up
  • CCRC08 replication status
• From last week: AOD replication to Tier2s for analysis - we need a higher level plan for identifying and managing the placement of data to Tier2s. Kaushik - have been discussing this, we have two new Panda hires coming on board. These are higher level services coming above the Tier2s. Need to bridge the gap between now and when these services would be available.
  • Meeting to discuss AOD data management - DataPlacementMinutesMar21

ATLAS requirements for storage elements (April 2)

• Follow-up - progress from sites
  • Now a formal requirement space tokens at the Tier2s. Outlined in Kor's document for CCRC08.
• AGLT2
• MWT2
• WT2
• NET2
• SWT2

LFC integration (John/Mark/Hiro)

• Follow-up: meeting held this Tuesday

Throughput initiative - status (Jay)

• Report from Monday's meeting

Panda release installation issues (Xin)

• Any release installation issues to follow up? Xin thinks we can start using it now. The issue is how to submit the pilots to do these jobs. There is a plan possible to use autopilot, but there may be problems. Xin will follow-up with Torre.
  • Last week No update - still tied up with Condor-G. Revisit this week.

Nagios Alerts - Focus review (Dantong)

• Any follow-up

Carryover action items

• Procurements
  • We need to come up with a good plan for the split between storage and CPU. There is some flexibility.
• Accounting: US ATLAS Facility view (Rob) - status: John Gordon follow-up with APEL developers; expect something in about a month.
