6 Slide The Time is Now David Britton, University of Glasgow GridPP24 6

7 Slide First Data Tier-1 Review RCUK International Review of e-Science Tier-1 Opening … and of course the GridPP4 proposal! Since GridPP23 David Britton, University of Glasgow 7 GridPP24

8 Slide First Data David Britton, University of Glasgow GridPP24 8 From an Atlas presentation to wLCG MB

9 Slide Tier-1 Review David Britton, University of Glasgow GridPP24 9 Third in a series of annual reviews of the Tier-1. Reviewers included three people from CERN. It was noted that the weekly Tier-1/experiments meeting had enhanced communications. The out-of-hour service had been successfully developed. The excellent performance of RAL during STEP09 was noted. The management processes had been successfully developed. Many (but not all) of the problems last autumn were related to the new building R89. The Tier-1 was encouraged to develop staff-agility to provide more cover. Concerns were voiced about the CASTOR upgrade path (GridPP24 discussion).

10 Slide RCUK e-Science Review David Britton, University of Glasgow 10 Report explicitly mentions: GridPPs expertise in large-scale distributed data management and analysis. Our work with start-up companies. The substantial secondary economic benefit arising from the ability to rapidly screen drugs "in-silico. GridPP resources were used in this way to screen potential agents in the fight against bird-flu and malaria. NGS and GridPP have been highly successful, providing many users with access to more computing power than they could otherwise easily obtain. Looking forward, we recommend that these efforts, including enhanced capacity and function of distributed storage, be sustained and expanded. RAL Tier-1

Mar 4 th – Last possible submission date Apr 15 th - PPRP May 14 th – PPRP Visiting Panel. 12 Weeks 3 Weeks

13 Slide Proposal Structure David Britton, University of Glasgow 13 WP-A: Tier-1 infrastructure and manpower; WP-B: Tier-2 infrastructure and manpower; WP-C: Grid deployment, operations and support; WP-D: Experiment-specific technical support; WP-E: Management team; WP-F: Impact Plan (Economic Impact, Knowledge Transfer and Outreach) WP-G: Travel and other costs. In the midst of writing the proposal we were told to reduce the project by 20%. This was very complex but is now built into submitted document. GridPP24

15 Slide Project Deliverables David Britton, University of Glasgow RCUK e-Science Review 15

16 Slide Hardware Requirements David Britton, University of Glasgow 16 LHC Schedule Experimen t Computing Models Global Resource Requirements UK Resource Requirements Hardware Costings UK Resource Request Scrutiny by C-RSG (April 2010), CRRB, LHCC (May 2010). UK Collaboration sizes A complex and evolving situation requiring constant management. Historically we have seen the integrated requirements are reasonably good-and-improving estimates of actual needs. Experience with real data (March+ 2010) Chamonix 2010 (Jan 2010) GridPP24

17 Slide Hardware Scaling David Britton, University of Glasgow 17 Tier-1 CPU Capacity KSI2K vs Year Hardware requirements have increased exponentially – fortunately Moores Law has held true with about the same time constant. Logarithmic scale RAL CPU costs Ramp for LHC start ~2-year Moores Law GridPP24

18 Slide Hardware Costs David Britton, University of Glasgow 18 Comparing predictions is even more difficult… For CPU, there is a remarkably good (in fact, too-good) agreement between the CERN and GridPP predictions. For Disk, factoring in different RAID strategies etc, estimates agree at about 5% level, which is better than the exchange-rate uncertainty alone. Conclude: GridPPs empirical approach leads to the same costing as an extensive top- down investigation of market and technology trends suggesting the Moores law assumption continues to be valid over the this time period. 27 pages GridPP24

19 Slide David Britton, University of Glasgow 19 The EGI/NGI Structure EGI.eu EMI EGI.inspire European Framework-7 proposals GridPP NGS NGI Operations NGI Operations Coordinator (John Gordon) Security Accounting and Monitoring Training/ Outreach Helpdesk and Regional Support NGI Management Board GridPP operates the largest scientific Grid in the UK and must ensure the UK NGI meets the needs of the large community we serve. We have identified certain tasks that are absolutely required by GridPP and wLCG, which have wider UK applicability and would sensibly be done in close collaboration as part of a larger team within a UK NGI. We have used this as a way to optimize our manpower, our leadership, and our influence in these areas. We believe that JISC is committed to funding an NGI at some level (signed up to EGI) but we have examined alternative scenarios and included in contingency. GridPP24

21 Slide Risks Register David Britton, University of Glasgow 21 … 22 high level risks analysed in proposal. Covered by: W.A. (0.5 FTE) WP-D Expt. Support WP-C Data Man. Old (atlas) building and other measures Tier-2 strategy W.A. (0.5 FTE) WP-C security team W.A. (1.0 FTE) GridPP24

22 Slide Risks Register - 2 David Britton, University of Glasgow 22 PPRP These risks are covered by the Contingency

23 Slide Publications David Britton, University of Glasgow 23 Maintain a list of publications (best- effort basis, so incomplete) on the GridPP website at: Currently 220 publications (2001 – 2009) papers: 22 papers,105 (~70 unique) authors GridPP24
