2 GridPP2 Budget David Britton, 4/12/03 Imperial College

2 Introduction £15.9m September* 2004 – September 2007 Possible additional £1m for LCG-2 3 FTE ring-fenced for non-LHC applications *Some transition spending will be needed from April The GridPP2 project, a continuation of GridPP, will deliver a full-scale production Grid to meet application requirements across the Particle Physics programme. The full deployment of Grid technology will make efficient use of resources to enable the UK to capitalise on investment in the LHC to meet the unprecedented challenges of LHC computing and enhance the discovery potential of UK physicists.

2 Following the PPRP review of the original £23.1m proposal two scenarios were presented to the Grid Steering Committee in July 03:  £17.3m “Reduced Programme” (£2.5m for LCG-2; £14.8m UK)  £19.6m “Regained Programme” (£2.5m for LCG-2; £17.1m UK) ( see With £15.9m we believe that we can still effectively fund the non- LCG part of the Regained Programme by modifying the planning assumptions as follows:  Reduced estimated of average staff costs at CCLRC.  New university appointments at Spine Point 11 rather than 13.  Reduction in the length of many posts (all posts end Sep 07). Overview

2 LCG (Tier-0) The UK contribution to LCG-2 at the 20% pro-rata level would be about £2.5m. Science Committee has presently reserved £1m for which a strong case will have to be made. GridPP-1GridPP-2 FY FY GridPP-1GridPP-2 FY FY ExploitnGridPP-2Exploitn FY FY This buys access to the Tier-0 and the LCG releases on which the UK PPGrid critically depends. An under-funded LCG2 jeopardizes the goals of GridPP2.

2 Tier – 1 The Tier-1 is the only resource completely under the control of GridPP with which international obligations can be met. It needs to be of a high standard. GridPP-1GridPP-2 FY FY GridPP-1GridPP-2 FY FY ExploitnGridPP-2Exploitn FY FY £5.3m, divided roughly equally between staff and hardware, buys a minimal UK Tier-1. This will be complimented by something like £2.7m from EGEE* (for UK support) and CCLRC. * EGEE assumed to be years

2 Tier – 2 The Tier-2s offer potential access to very significant resources but their distributed nature and the need to dove-tail with local policies and non-HEP usage, make them less predictable. GridPP-1GridPP-2 FY FY GridPP-1GridPP-2 FY FY ExploitnGridPP-2Exploitn FY FY £2.3m buys access to the substantial hardware (£3m  £8m) resources at the institutes. Complimented by ~£1.7m from EGEE (for UK support) and in-house contributions.

2 Applications The applications themselves are developed by the respective experiments within their own international context. GridPP provides funding to help interface the applications to the Grid. GridPP strongly encourages joint projects. GridPP-1GridPP-2 FY FY GridPP-1GridPP-2 FY FY ExploitnGridPP-2Exploitn FY FY £3.0m enables the UK groups to take a leading role in interfacing the experiment applications to the Grid. This is complemented by large international efforts and by ~£5m funding from SR2002 to the LHC experiments.

2 Middleware/Security/Networking The GridPP2 proposal identifies 5 areas of involvement that are either mission- critical or capitalize on UK leadership. Many of these areas lever FP VI funding. £3.1m addresses these areas and levers ~£1.7m of FP VI funding.

2 Operation & Management The number of Managers is reduced in GridPP2 but the new Dissemination officer and Production Manager are also counted here, leading to the apparent increase. GridPP-1GridPP-2 FY FY GridPP-1GridPP-2 FY FY ExploitnGridPP-2Exploitn FY FY Management (£0.9m), travel (£0.8m), and operations (£0.5m) The travel budget for GridPP2 was scaled from GridPP1 by the number of FTE supported but without any inflation compensation.

2 Element Summary EGEE assumed to be years with second phase funding the same as the first. Four EGEE funded posts are assumed to be at the Tier-2 centres, the remaining at Tier-1 GridCC and DAGGR projects assumed to proceed for 2 years in line with the FTE numbers in the tender document. This funding is not yet established. Tier-2 hardware numbers are subject to revision after the MOU information is gathered. CCLRC is assumed to contribute 3 FTE for four years in addition to £1.12m of legacy hardware.

2 Notes We plan to regard 10% of the Tier-1 hardware budget (10% of £2.4m) as contingency (this is a 1.5% contingency on the project.) The staff costs include an inflation factor but a degree of uncertainty remains with respect to to spine point at appointment and no annual increments have been built in. To address this, the staff costs have been inflated by 3% in the current planning. A substantial increase in university indirect costs could not be absorbed. Travel has been scaled from GridPP1 experience but without inflation. This implies a similar number of GridPP collaboration meetings and a similar travel policy but with a possible call on the contingency. GridPP1 has not supported LTA as a cost-effective investment of resources. In GridPP2 any requests for LTA or extended travel would be considered on a case-to-case basis and would require a call on the contingency.

2 Conclusion Using modified planning assumptions we believe we can fund the “Regained Programme” originally presented to the Grid Steering Committee. The CB is asked to approve this plan as presented today.
