  1. Summary of the ScotGRID Project Phase2 of the ScotGRID Project Phase1 of the ScotGRID Project Introduction: ScotGRID Goals ScotGRID:The Scottish LHC Computing Centre

  2. 2000: JREI Bid The LHC Computing Challenge for Scotland ScotGRID: The Spirit of the Project The JREI funds will make possible to commission and fully exercise a prototype LHC computing centre in Scotland The Centre would provide: Technical service based for the grid services DataStore to handle samples of data Analysis Significant simulation production capability Excellent network connection RAL / Regional sites Support grid middle devel. with CERN/RAL Support core software devel. within LHCb/ATLAS Support user applications in other scientific areas • This will enable us to answer: • Grid viable solution for LHC computing challenge,TDR • Can a two-site Tier-2 centre be setup and operate effectively • How can network topology between Ed,GL, RAL & CERN http://www.scotgrid.ac.uk/

  3. Time-Line for a Production Tier-2 & beyond Completed: Phase1 Phase2 Links to other applications… Future Upgrades ? Production Tier-2 Site Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 2003 2004 2005 2001 2002 Start of GridPP-II Prototype To Production End of JREI funding Start of ScotGRID-II Delivery of more Kit…

  4. ScotGRID Processing nodes at Glasgow • 59 IBM X Series 330 dual 1 GHz Pentium III with 2GB memory • 2 IBM X Series 340 dual 1 GHz Pentium III with 2GB memory • 3 IBM X Series 340 dual 1 GHz Pentium III with 2GB memory • 1TB disk • LTO/Ultrium Tape Library • Cisco ethernet switches ScotGRID Storage at Edinburgh • IBM X Series 370 PIII Xeon • 70 x 73.4 GB IBM FC Hot-Swap HDD Hardware Middleware Applications

  5. Documentation Accumulated CPU Use http://www.scotgrid.ac.uk/ Instantaneous CPU Use Tier-2 Web-Based Monitoring Total Disk Use ScotGrid reached ~ 580,000th processing hour

  6. ScotGrid accumulated stats Significant non-LHC application use Q3 Q1 Q2

  7. ScotGrid JREI project includes a mid-term hardware upgrade. • As part of GridPP planning, we need to upgrade from Prototype to Production Tier 2 status by 2004. • JREI funding left to be spent by June 2003: • Edinburgh £220k • Glasgow £30k £250k ScotGRID Phase-2 : Just Started

  8. Summary of ScotGRID Upgrade Upgrade Database Server in Edinburgh xSerier 440 (8 Way 1.9GHz Intel Xeon, 1MB L3 Cache, 32GB Memory, 36GB Internal Disk) 16 – 20 TB of Disk Storage in Edinburgh FAStT700 or FAStT900 (see next slide) • 5 TB of Disk Storage in Glasgow • Agreed to relocate existing FAStT500 from Edinburgh to Glasgow Edge Servers for Edinburgh EDG SE:1 from Glasgow (x340) LCFG, CE: 2* x205, 1 x 1.8 GHz, 256MB, 40GB New Kit for Glasgow CDF & eDIRT Kit

  14. Summary of Tier-2 ScotGRID Project • Have Successfully completed Phase-1 • ScotGRID had been upgraded – Phase-2 • eDIRT Kit, CDF Kit • HPS + Larger DataStore • ScotGRID: will concentrate on commissioning the new hardware during the next few month. before going to EDG2.0 • There will be an ad. for ScotGRID Technical Coordinator • We will have to start to think about restructing the ScotGRID team for production running – early next year • In the New Year plan to integrate the Durham CPU Farm
