  3. What was GridPP1? • A team that built a working prototype grid of significant scale > 2,000 (9,000) CPUs > 1,000 (5,000) TB of available storage > 1,000 (6,000) simultaneous jobs • A complex project where 88% of the milestones were completed and all metrics were within specification A Success “The achievement of something desired, planned, or attempted” Collaboration Board

  4. What is GridPP2? Structures agreed and in place (except LCG phase-2) • 253 Milestones, 112 Monitoring Metrics at present. • Must deliver a “Production Grid”: robust, reliable, resilient, secure, stable service delivered to end-user applications. • The Collaboration aims to develop, deploy and operate a very large Production Grid in the UK for use by the worldwide particle physics community. Collaboration Board

  5. SCALE: GridPP will deliver Grid middleware and hardware infrastructure to enable the construction of a UK Production Grid for the LHC of significant scale. INTEGRATION: The GridPP project is designed to integrate with the existing Particle Physics programme within the UK, thus enabling full use of Grid technology and efficient use of shared resources. DISSEMINATION: The project will disseminate the GridPP deliverables in the multi-disciplinary e-Science environment and will seek to build collaborations with emerging non-PPARC Grid activities both nationally and internationally. UK LHC COMPUTING: The main aim is to provide a computing environment for the UK Particle Physics Community capable of meeting the challenges posed by the unprecedented data, processing and analysis requirements of the LHC experiments. OTHER UK PARTICLE PHYSICS COMPUTING: The process of creating and testing the computing environment for the LHC will naturally support the current and next generation of highly data intensive Particle Physics experiments. EGEE: Grid technology is the framework used to develop the required capability: key components will be developed as part of the EGEE project and elsewhere. LCG: The collaboration builds on the strong computing traditions of the UK at CERN. GridPP will make a strong contribution to the LCG deployment and operations programme. INTEROPERABILITY: The project is integrated with national and international developments from other Grid projects and the GGF in order to ensure a common set of principles, protocols and standards that can support a wide range of applications. INFRASTRUCTURE: Provision is made for a Tier-1 facility at RAL and four Regional Tier-2s, encompassing the collaborating Institutes. OTHER FUNDING: The Tier-1 and Tier-2s will provide a focus for dissemination to the academic and commercial sector and will attract additional funds such that the full programme can be realised. Vision Collaboration Board

  6. What are the Grid challenges? • Must • share databetween thousands of scientists with multiple interests • link major (Tier-0 [Tier-1]) and minor (Tier-1 [Tier-2])computer centres • ensure all data accessible anywhere, anytime • grow rapidly, yet remainreliablefor more than a decade • cope withdifferent management policiesof different centres • ensure data security • be up and running routinely by2007 Collaboration Board

  7. What are the Grid challenges? 2. Software efficiency 1. Software process 3. Deployment planning 4. Link centres 10. Policies 5. Share data Data Management, Security and Sharing 9. Accounting 8. Analyse data 7. Install software 6. Manage data Collaboration Board

  8. LCG Overview • By 2007: • 100,000 CPUs • - More than 100 institutes worldwide • building on complex middleware being developed in advanced Grid technology projects, both in Europe (Glite) and in the USA (VDT) • prototype went live in September 2003 in 12 countries • Extensively tested by the LHC experiments during this summer Collaboration Board

  9. Data Challenges • Ongoing.. • Grid and non-Grid Production • Grid now significant • ALICE - 35 CPU Years • Phase 1 done • Phase 2 ongoing LCG • CMS - 75 M events and 150 TB: first of this year’s Grid data challenges Entering Grid Production Phase.. Collaboration Board

  10. Data Challenge • 7.7 M GEANT4 events and 22 TB • UK ~20% of LCG • Ongoing.. • (3) Grid Production • ~150 CPU years so far • Largest total computing requirement • Small fraction of what ATLAS need.. Entering Grid Production Phase.. Collaboration Board

  11. LHCb Data Challenge 186 M Produced Events Phase 1 Completed 3-5 106/day LCG restarted LCG paused LCG in action 1.8 106/day DIRAC alone 424 CPU years (4,000 kSI2k months), 186M events • UK’s input significant (>1/4 total) • LCG(UK) resource: • Tier-1 7.7% • Tier-2 sites: • London 3.9% • South 2.3% • North 1.4% • DIRAC: • Imperial 2.0% • L'pool 3.1% • Oxford 0.1% • ScotGrid 5.1% Entering Grid Production Phase..

  13. Issues “LCG-2 MIDDLEWARE PROBLEMS AND REQUIREMENTS FOR LHC EXPERIMENT DATA CHALLENGES” First large-scale Grid production problems being addressed… at all levels https://edms.cern.ch/file/495809/2.2/LCG2-Limitations_and_Requirements.pdf Collaboration Board

  14. Coordinates resources that are not subject to centralized control … using standard, open, general-purpose protocols and interfaces … to deliver nontrivial qualities of service YES. This is why development and maintenance of LCG is important. YES. VDT (Globus/Condor-G) + EDG/EGEE(Glite) ~meet this requirement. YES. LHC experiments data challenges over the summer of 2004. 5 Is GridPP a Grid? http://www-fp.mcs.anl.gov/~foster/Articles/WhatIsTheGrid.pdf http://agenda.cern.ch/fullAgenda.php?ida=a042133 Collaboration Board
