16:15 Update on Targets and Milestones for 2007

1. Demonstrate Tier0-Tier1 data export at 65% of full nominal rates per site using experiment-driven transfers
   • Load generators for ALICE, ATLAS & CMS ok
2. Demonstrate Tier0-Tier1 data export at 50% of full nominal rates (as above) in conjunction with T1-T1 / T1-T2 transfers
   • Inter-Tier transfer targets taken from ATLAS DDM tests / CSA06 targets
3. Demonstrate Tier0-Tier1 data export at 35% of full nominal rates (as above) in conjunction with T1-T1 / T1-T2 transfers and reprocessing / analysis stripping at Tier1s
   • Tier1 production activity needs to be defined per-VO and depends on computing model / production plans for that VO.
4. Provide SRM v2.2 endpoint(s) that implement(s) all methods defined in SRM v2.2 MoU, all critical methods pass tests
   • Proposal that requirement on bring online methods be relaxed as that they are not required in Q1 2007. (i.e. can still pass milestone without them, e.g. success with).

Questions:

• With respect to milestone 3 above, could a generic sub-milestone be written that is VO-independent, e.g. every file transferred to a Tier1 is read at least once by a Grid job running at that site?
  • This would allow VO-specific milestones, e.g. that couple to conditions DB deployment models, to remain as experiment milestones, which is probably where they belong...
  • Some explicit targets for the WMS at each Tier1 would nevertheless have to be established (derived from the above).
• Does it make sense to have (an) explicit database milestone(s) at this level? (Which would clearly have to be experiment-specific).
  • Maybe same comment as above applies...
