  1. Grid NIKHEF Jamboree 22 december 2005 Jeff Templon PDP Group, NIKHEF Throbbing jobs Googled Grid

  2. The PDP spear points • Operations • Installing, operating, maintaining NIKHEF grid systems • Feed improvements back into system • Worldwide Deployment Coordination (Bos: GDB Chair) • Software • Security (Groep, Venenkamp, Koeroo, Steenbakkers) • How to organize, identify, authorize, manage user groups • Big win: important aspect with few experts (several @ NIKHEF) • Integration / certification / packaging for VL-E (van Dok, Keijser) • Worldwide Grid “trust management” coordination (Groep: IGTF Chair) • Applications (Klous, Templon, Groep) • Helping people / groups become effective grid users • Evangelism • ATLAS Trigger (on Grid)

  3. PDP operations • Ronald Starink, David Groep, JT, Paul Kuipers, Ton Damen • Some statistics for last six weeks • 27 problem reports • 21 Willem van Leeuwen • 2 Philips • 2 LCG operations team • 1 SARA • 1 ATLAS operations • Almost all concern job submission problems

  4. PDP ops 2 • From our system actions log: • 45 restarts of batch system components • 16 broken nodes removed from system for repairs • 14 repaired nodes returned to service • 13 restarts of ‘nscd’ service • 5 restarts of resource broker • Handful of node reboots (‘stuck’) • One major upgrade (batch system torque 1.2 -> 2.0)

  5. Common Question to Grid Guys Why are physicists at a HEP lab spending timeworrying about computing problems inbioinformatics and earth sciences? BIG GRID

  6. What is BIG GRID? • Infrastructure based on supporting science cases • Biology (food informatics, drug discovery, proteomics) • Linguistic and cultural studies • Astronomy (LOFAR) • High-Energy Physics (LHC) • Industrial Research (GEANT4 sims by Philips!!!) • Total budget 30 M€ (almost all either stuff or operating costs)

  7. What’s in BIG GRID? • THE WORKS for HEP: full Tier-1 for ATLAS / LHCb / ALICE • Distributed / central computing infra for biomed • LOFAR data center • Cluster for in silico industrial research (hosted by Philips) • “other” -- common pool for disciplines who don’t have good estimates • All tied together with grid tools & infrastructure • Operating funds for four years (cooling / electricity) + small operational manpower budget

  8. Writing Team: Kors Bos, David Groep, Frank Linde, Arjen van Rijn, JTBob Hertzberger (UvA), Gert Vriend (Nijmegen), Peter Michielse (NCF) Proposal Pre-Rejection: Gerard v/d Steenhoven, Stan Bentvelsen,Marcel Merk Mr. Telephone: Arjen van Rijn Presentation at NWO Interview:Frank Linde

  9. What’s Up for 2006 • BIG GRID organization • EGEE-2 starts (approved last week!) • Ramp Up (CPU factor 3, disk factor 10) • Calm down LCG management (deploying empty capacity) • Guidance of new BIG / VL-E user communities • Continued improvements in facilities & software • Experiments: please test ANALYSIS models!!! • Experiment Computing Operations • Assumed coming from T1 physics groups • Do we want this??

  10. Progress at SARA LCG Service Challenge II “The Dutch Contribution”
