WLCG Mini-Review: Goals, 2008 Summary, and 2009 Plans for Enhanced Performance

This mini-review focuses on the primary objectives for the current evaluation, assessing both 2008 achievements and 2009 plans based on the discussed schedule in Chamonix. Key elements include a concise summary of 2008 activities, an evaluation of the current performance against the anticipated TDR, and a list of issues to address in 2009. The review will also cover the evolution of the computing model, optimization efforts by experiments, and provide detailed status reports from various tiers and experiments, ensuring clarity in performance assessment.

  1. WLCG Mini-review: goals • The main goal of the review this time would be to • 1.1 Very short summary of 2008 activities • 1.2 Plans for 2009 in view of the schedule discussed in Chamonix • 1.3 Clear Picture of the current Performance compared to TDR anticipated one • 1.4 List of pending issues for 2009 running • Concerning 1.3, during the last LHCC there were few points we should address during this meeting • How the detector now perform compared to TRD • How the computing model for the experiments have been evolved • Efforts carried out by experiments to optimize the performance of their software

  2. Agenda • 09:0011:20    Part 1 Convener: Mario Martinez-Perez (IFAE) • 09:00 Project status (40') 2009 planning and resources • 09:40 Summary of 2008 LCG operation (20') - Performance and experience • 10:00 Status of Application Area (30') • 10:30  break (15') • 10:45 Middleware (EGEE , OSG, NDGF) (30') • 11:15 Networking (10') • 11:2514:10    Part 2 Convener: Chris Hawkes (Birmingham) • 11:25 Status of Tier0 (30') - Resources, performance of mass storage, castor, etc.. • 11:55 CAFs Status at CERN (20') • 12:15  lunch (1h00') • 13:10 Status of Tier 1s (30') – here in addition to the general status, it would be interesting to focus on couple of examples. - here we also expect report on performance • 13:40 Status of Tier 2s (30') • 14:1015:50    Part 3 Convener: Jean-FrancoisGrivaz (LAL) • 14:10 Review of experiments (20') – 2008 summary and 2009 plans - Current status/performance vs Computing TDR - It is particularly relevant to get a clear picture on how close the experiments are now to their original TDR operational model/anticipated performance • ATLAS (25') • CMS (25') • LHCb (25') • ALICE (25')
