Resources – next steps

C-RRB today: Updated requests presented as discussed C-RSG prelim report – concluded that 2008/9 pledges should be

sufficient for 2009/10 But this was strongly contested by the experiments, and all agreed

that more work was needed to understand really the models and assumptions

DG proposed: Experiments and RSG work together to resolve differences and make a

recommendation by the summer (needed in any case for September to make decisions for 2010 resources)

We (WLCG) should schedule a meeting with all concerned Experiments, C-RSG, and LHCC referees

We also need to discuss how to present estimated requirements for 2011/12 – funding agencies asking for these now

Other points

EGEE – EGI transition is critical – need to ensure that the WLCG service is not disrupted We must discuss the NGI plans in the upcoming GDBs

Monitoring of resources and tools must be automated ... These will be essential in understanding usage and efficiency and in particular bottlenecks and experiment model problems ... Do we need to do more here? Partly RRB etc do not understand all the tools and monitoring that we

have
