GridPP Funding Model(s) D. Britton Imperial College 24/5/01 £21m + £5m
Starting Constraints D. Britton Imperial College 24/5/01 £2.4m – PPARCs commitment to EU DataGrid. £7-10m – PPARCs promise to CERN. £1.8m – BaBar Tier A / £4m – 50% Tier-1 £x m – PPARCs displacement plan. ~ £20m Limited manoeuvring room!

GridPP Proposal: Allocation to Work Groups D. Britton Imperial College 24/5/01 Table 10: Allocation of effort to sets of WorkGroups.

At 54K/FTE this gives £10.3m. Managers are additional £0.4m
GridPP Proposal: Summary D. Britton Imperial College 24/5/01 The proposal requests funding to construct (£3.0m) and operate (£2.4m) a Tier-1A centre. It identifies the need for external funding to upgrade this to a 50% Tier-1 centre for LHC and to construct a number of Tier-2 Centres (£7.3m). It funds hardware (£1.4m) and staff (£5.7m) at CERN. It honours commitments made to DataGrid (£2.4m). It allocates the remaining £6.1m for staff effort to the GridPP workgroups but recognises that this is insufficient to satisfy many of the aspirations/obligations.
GridPP Proposal: Summary D. Britton Imperial College 24/5/01 ~52% UK Staff
Tensions within the GridPP Proposal D. Britton Imperial College 24/5/01 The experiments need vastly increased effort ~ £10m. Hardware minimum commitment is low by ~£2m The EU commitment includes operation of a test-bed so groups G-H are under funded by ~£2m. Work groups A-F are under-funded by ~£3m. Dissemination is under-funded by £2m. When and how will the £8m problem with the core grant reappear? Have we had input from all interested groups? How much money will be really get, and when?

Planning beyond the Submission D. Britton Imperial College 24/5/01
Conclusions D. Britton Imperial College 24/5/01 We have a responsive financial model but we dont yet have the input to which it needs to respond. Even in the most optimistic scenario (the submission) there is not enough money to satisfy all the constraints, obligations and aspirations of the community. Hard decisions are going to have to be made. We need to take this opportunity to establish the over-reaching strategic principles that will guide those decisions. We must keep sight of the vision in the face of all the painful detail (and vice-versa!)
