  1. GridPP: status report Andy Parker(Taken from GridPP report at OSC by Tony Doyle) Oversight Committee

  2. 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” Oversight Committee

  3. 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. Oversight Committee

  4. 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 Oversight Committee

  5. 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.. Oversight Committee

  6. Paradigm ShiftTransition to Grid… 424 CPU · Years May: 89%:11% 11% of DC’04 Jun: 80%:20% 25% of DC’04 Jul: 77%:23% 22% of DC’04 Aug: 27%:73% 42% of DC’04 Oversight Committee

  7. 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 Oversight Committee

  8. UK Tier-1/A Centre Rutherford Appleton Laboratory Grid Resource Discovery Time = 8 Hours • High quality data services • National and international role • UK focus for international Grid development 1000 CPU 200 TB Disk 60 TB Tape (Capacity 1PB) 2004 Disk Use 2004 CPU Utilisation Oversight Committee

  9. UK Tier-2 Centres ScotGrid Durham, Edinburgh, Glasgow NorthGrid Daresbury,Lancaster, Liverpool, Manchester, Sheffield SouthGrid Birmingham, Bristol, Cambridge, Oxford, RAL PPD,Warwick LondonGrid Brunel, Imperial, QMUL, RHUL, UCL Oversight Committee

  10. * Leeds Manchester * * DL * Oxford RAL * • In future will include services to facilitate collaborative (grid) computing • Authentication (PKI X509) • Job submission/batch service • Resource brokering • Authorisation • Virtual Organisation management • Certificate management • Information service • Data access/integration • (SRB/OGSA-DAI/DQPS) • National Registry (of registry’s) • Data replication • Data caching • Grid monitoring • Accounting Level-2 Grid Oversight Committee

  11. Application Development ATLAS LHCb CMS SAMGrid (FermiLab) BaBar (SLAC) QCDGrid PhenoGrid Oversight Committee

  12. More Applications • ZEUS uses LCG • needs the Grid to respond to increasing demand for MC production • 5 million Geant events on Grid since August 2004 • QCDGrid • For UKQCD • Currently a 4-site data grid • Key technologies used • - Globus Toolkit 2.4 • - European DataGrid • eXist XML database • managing a few hundred gigabytes of data Oversight Committee

  14. Grid and e-Science Support in 2008 I. Experiment Layer II. Application Middleware III. Grid Middleware IV. Facilities and Fabrics What areas require support? IV Running the Tier-1 Data Centre IV Hardware annual upgrade IV Contribution to Tier-2 Sysman effort  (non-PPARC) hardware IV Frontend Tier-2 hardware IV Contribution to Tier-0 support III One M/S/N expert in each of 6 areas III Production manager and four Tier-2 coordinators II Application/Grid experts (UK support) I ATLAS Computing MoU commitments and support I CMS Computing MoU commitments and support I LHCb Core Tasks and Computing Support I ALICE Computing support I Future experiments adopt e-Infrastructure methods • No GridPP management: (assume production mode established + devolved management to Institutes) Oversight Committee

  15. OSC actions • Plan for support of physics analysis community in 2007 • Better understanding of capacity limits at Tier1 and strategic priorities • £1M bid for LCG2 to go to PPARC Science Committee • Plan to raise job completion efficiency • Statement on gLite • OSC views project as excellently managed and very successful Oversight Committee
