Background: PMB preliminary discussions in September PPAP presentation in October: Resources needed in medium-long term?

3. Tony Doyle - University of Glasgow 12 January 2005Collaboration Board Tier 0 and LCG: Foundation Programme Aim: build upon Phase 1 Ensure development programmes are linked Project management: GridPPLCG Shared expertise: LCG establishes the global computing infrastructure Allows all participating physicists to exploit LHC data Earmarked UK funding being reviewed Required Foundation: LCG Deployment F. LHC Computing Grid Project (LCG Phase 2) [review]

4. Tony Doyle - University of Glasgow 12 January 2005Collaboration Board Tier 0 and LCG: RRB meeting (October) Jos Engelen proposal to RRB members (Richard Wade [UK]) on how a 20MCHF shortfall for LCG phase II can be funded Spain to fund ~2 staff. Others at this level? Funding from UK (£1m), France, Germany and Italy for 5 staff. Others? Now vitally important that the LCG effort established predominantly via UK funding (40%) is sustained at this level (~10%) Proposal to SC in preparation Value to the UK? Required Foundation: LCG Deployment
