Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting GridPP Report Tony Doyle

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting Beyond GridPP 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 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 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.

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting Enabling Grids for E-science in Europe 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

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting 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 “3 rd parties” –Glasgow, ICSTM, Leeds, Manchester, Oxford Funded effort dedicated to deploying regional grids UK T2 coordinators

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting 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-2E-Science and LCG-2 (26 Oct 2004) and feedback from CB (12 Jan & 7 July 2005)

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting Grid and e-Science funding requirements Simple model

Tony Doyle - University of Glasgow Priorities: GridPP2 Proposal 1.Tier-1/A staff – National Grid Centre 2.Tier-1/A hardware – International Role 3.Tier-2 staff – UK e-Science Grid 4.Applications –Grid Integration (GridPP2) –Development (experiments proposals) 5.Middleware – EU-wide development 6.Tier-2 hardware – non-PPARC funding 7.CERN staff – quality assurance 8.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 July 2005Collaboration Board Meeting Grid and e-Science funding requirements Simple model

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting 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 Physicists, All Simulation Production LHCb - MC Production, No analysis

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting UK Analysis for the LHC Experiments II UK Tier-1 (~7% of Global Tier-1): UK Tier-2 (pre-SRIF3):

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting Priorities in context of a financial snapshot in 2008 Grid (£5.6m p.a.) and e-Science (£2.7m p.a.) Assumes no GridPP project management Savings? –EGEE Phase 2 ( ) may contribute –UK e-Science context is 1.NGS (National Grid Service) 2.OMII (Open Middleware Infrastructure Institute) 3.DCC (Digital Curation Centre) Grid and e-Science funding requirements To be compared with Road Map: Not a Bid - Preliminary Input

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting 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

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting FEC? Computers funded via SRIF3 (+  SRIF4?) – 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)

Tony Doyle - University of Glasgow 8 July 2005Collaboration Board Meeting 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 ManpowerPower, Space FEC model = ?? Comment: Dual Funding was excellent value for HEP Comment: Tier-2 functionality is needed (wherever it resides)
