  1. GridPP Report Tony Doyle Collaboration Board Meeting

  2. Beyond GridPP2.. 2. Funding from September 2007 will be incorporated as part of PPARC’s request for planning input for LHC exploitation from the LHC experiments and GridPP that will be considered by a Panel consisting of Prof. G. Lafferty (Chair), Prof. S. Watts and Dr. P. Harris meeting over the summer to provide input to Science Committee in the Autumn. 1. An important issue to note is the need to ensure matching funding is fully in place for the full term of EGEE-2, anticipated to be 1st April 2006 to 31st March 2008. Such funding for SA1 and JRA1 is currently provided by PPARC through GridPP2, but this will terminate under current arrangements at the end of GridPP2 in August 2007. There is thus a 7 month gap for which matching funding is currently not in place. This needs to be resolved, with some urgency, before the proposal is submitted this summer. Collaboration Board Meeting

  3. Deliver a 24/7 Grid service to European science build a consistent, robust and secure Grid network that will attract additional computing resources. continuously improve and maintain the middleware in order to deliver a reliable service to users. attract new users from industry as well as science and ensure they receive the high standard of training and support they need. 100 million euros/4years, funded by EU >400 software engineers + service support 70 European partners Enabling Grids for E-science in Europe Collaboration Board Meeting

  4. Overview EGEE is the Grid Infrastructure Project in Europe • Take the lead in developing roadmaps, white papers, collaborations • Organise European flagship events • Collaborate with other projects (including CPS) • start date = April 1 • UK partners • CCLRC+NeSC+PPARC (+TCD) (n.b. UK e-Science, not only HEP) • NeSC : Training, Dissemination & Applications • NeSC : Networking • CLRC : Grid Operations, Support & Management • CLRC : Middleware Engineering (R-GMA) • UK “3rd parties” • Glasgow, ICSTM, Leeds, Manchester, Oxford • Funded effort dedicated to deploying regional grids • UK T2 coordinators Collaboration Board Meeting

  5. Beyond GridPP2.. LHC EXPLOITATION PLANNING REVIEW Input is requested from the UK project spokespersons, for ATLAS and CMS for each of the financial years 2008/9 to 2011/12, and for LHCb, ALICE and GridPP for 2007/8 to 2011/12. Physics programme Please give a brief outline of the planned physics programme. Please also indicate how this planned programme could be enhanced with additional resources. In total this should be no more than 3 sides of A4. The aim is to understand the incremental physics return from increasing resources. Input will be based upon PPAP roadmap input E-Science and LCG-2 (26 Oct 2004) and feedback from CB (12 Jan & 7 July 2005) Collaboration Board Meeting

  6. Grid ande-Sciencefunding requirements • Simple model Collaboration Board Meeting

  7. Priorities:GridPP2 Proposal • Tier-1/A staff – National Grid Centre • Tier-1/A hardware – International Role • Tier-2 staff – UK e-Science Grid • Applications • Grid Integration (GridPP2) • Development (experiments proposals) • Middleware – EU-wide development • Tier-2 hardware – non-PPARC funding • CERN staff – quality assurance • CERN hardware – pro-rata contribution • Established entering proposal writing phase… ALL of these are required to address the LHC Computing Challenge Tony Doyle - University of Glasgow

  8. Grid ande-Sciencefunding requirements • Simple model FEC (2010..) some concerns.. Collaboration Board Meeting

  9. UK Analysis for the LHC Experiments I • The basic functionality of the Tier-1 is: • ALICE - Reconstruction, Chaotic Analysis • ATLAS - Reconstruction, Scheduled Analysis/strimming, Calibration • CMS - Reconstruction • LHCb - Reconstruction, scheduled strimming, chaotic analysis • The basic functionality of the Tier-2s is: • ALICE - MC Production, Chaotic Analysis • ATLAS - Simulation, Analysis, Calibration • CMS - Analysis for 20-100 Physicists, All Simulation Production • LHCb - MC Production, No analysis Collaboration Board Meeting

  10. UK Analysis for the LHC Experiments II • UK Tier-1 (~7% of Global Tier-1): • UK Tier-2 (pre-SRIF3): Collaboration Board Meeting

  11. Management? • Current Proposed Model is low cost • SCAP PPARC committee provide overview – (comment: PPARC could e.g. appoint a project leader) • Production manager (PPARC) + 4 Tier-2 coordinators (EU) + Operations Centre • (comment: EU funding likely in 2008 on.. But will it fund these people?) • No PMB, CB – devolution to institutes • Some concerns that this will not work Collaboration Board Meeting

  12. FEC? • Computers funded via SRIF3 (+eSRIF4?) – OK up to 2010 [see Steve’s slides] • However, in future - CHARGE: • Power usage • support staff time • maintenance (routine/emergency) • space charges • share of the replacement capital item cost (if so, effect comes earlier than end of SRIF) Collaboration Board Meeting

  13. FEC? Back of envelope • Estimated costs per annum • Power usage (200 CPUs +disk) ~50k • support staff time ~50k • maintenance (routine/emergency) ~? • space charges ~? • replacement capital item cost ~50k • FEC ~150k [None of this “scales” but…] 5,000 CPUs ~ £4m p.a. Current proposed model = £2m via SRIF + £1.3m PPARC + £0.7m Institutes Hardware Manpower Power, Space • FEC model = ?? • Comment: Dual Funding was excellent value for HEP • Comment: Tier-2 functionality is needed (wherever it resides) Collaboration Board Meeting
