  1. GridPP Prof. David BrittonGridPP Project leader University of Glasgow Oversight Committee Meeting 18th June 2010 IET, Oct 09

  2. High-Level View • The LHC is running; luminosity is increasing; data is flowing through the worldwide LHC computing Grid. • The UK Grid is functioning smoothly and providing a good service to the experiments. • In the European arena, EGI and EMI have been approved and have started; ROSCOE and CUE were not funded. • The GridPP4 proposal has been written, descoped (20%), submitted, reviewed, defended, descoped (5%), defended, descoped (5%) …. • The growing uncertainty about GridPP4 funding is our single biggest concern, specifically related to retention of key staff.

  3. LHC Integrated Luminosity ~100k CPU-days/day GridPP Oversight Committee

  4. UK Performance The UK has performed well since data taking started; plots cover March, April and May 2010. The 2010 hardware pledges have been met. Delivering to all LHC experiments at the expected level. UK a leading contributor Three UK sites in the top 18 ATLAS analysis sites (incl. T1s) UK CPU efficiency is competitive GridPP Oversight Committee

  5. Hardware (Re-) Planning • Jan/Feb: New LHC schedule agreed. • April/May: C-RSG/LHCC agreed new experiment requirements. • May/June: GridPP re-planned up to 2015 for the GridPP4 proposal. • Overall reduction in the required Disk and CPU, but a significant increase in the requirement for Tape. • Dove-tail GridPP3 FY10 spend and GridPP4 planning, constrained by the reduced FY10 capital allocation. GridPP Oversight Committee

  6. FY10 Tier-1 hardware • FY10 Tier-1 hardware budget plan reduced from £2.24m to £1.2m at STFC’s request. • We achieve this in two ways: • The new experiment estimates based on the Chamonix LHC schedule have reduced FY10 requirements* and allowed us to reduce spend. • We have delayed some spend on tape infrastructure into GridPP4**. • STFC’s restriction appears to be mainly in capital (£1.1m) • Have been allocated £100k “resource” • Will be difficult to purchase required licenses, network etc. within this budget (cf £226k in FY09) • Would like to understand scope for increasing non-capital spend. • Also acknowledges difficult financial situation in many countries. • **Very recent information suggests a new roadmap for tape infrastructure; some further re-planning will be necessary but costs are likely to be reduced/delayed.

  7. Finances - summary GridPP Oversight Committee

  8. FY09 Spend • We were able to move entire disk procurement forward, to meet STFC’s request for increased capital spend in FY09. • Second round of T2 hardware grants are almost complete. • FY09 grants were all issued before the end of the financial year. • Procurements based on FY10 grants are underway, but introduced a delay in meeting 2010 Tier-2 disk pledge at a number of institutes. • SLA staff costs were within 1% of estimate. • FY09 travel costs were within budget, including a rebate of £28k from EGEE. • We see travel costs increasing slightly now the LHC is online. GridPP Oversight Committee

  9. Staffing RAL staff now all in place, including posts where recruitment was delayed. 98% of expected funded effort delivered in FY09, plus 23.8 FTE of unfunded effort. But starting to see staff turnover, especially at Tier-2s. GridPP Oversight Committee

  10. ProjectMap Q110 GridPP Oversight Committee

  11. ProjectMap stats • Metrics status similar to in previous quarters • Red metrics mainly due to various short-term issues such as delayed disk procurements, APEL downtime. • 65% of milestones now complete (project has run 2 out of the 3 years). 3 milestones are ‘red’: • Service agreements with NGS; move from ATLAS centre; shut-down of ADS service GridPP Oversight Committee

  12. Risk register • 3 high risks: • R1: Recruitment and retention. Becoming more likely as staff fear delays and cuts in GridPP4 funding. • R2: Sudden loss of key staff. As for R1. • R27: Uncertain long term funding. Impact increases as we approach the start of GridPP4. GridPP Oversight Committee

  13. Conclusion Technically the project is running very well and we are delivering to the wLCG and the experiments according to plan. We anticipate things will get harder as the machine luminosity and integrated data volume increases, but we believe we are prepared. It is a very busy time, from a management perspective. Our biggest concern is the uncertainty surrounding the future. GridPP Oversight Committee
