  1. ICHEP visit to NIKHEF

  2. D0 Monte Carlo farm hoeve (farm) MC request 50 800 MHz 2-CPU nodes 50 * 40 GB schuur (barn) SAM 1.2 TB

  3. D0 Monte Carlo production EDG testbed D0 farm DAS cluster schuur (barn) SAM

  4. WAN LAN SAM on the Global Scale Datalogger MSS MSS Reco-farm Central Analysis ClueD0 (Others) • Current active stations • FNAL (several) • Lyon FR (IN2P3), • Amsterdam NL (NIKHEF) • Lancaster UK • Imperial College UK • Others in US Stations at FNAL MSS Interconnected network of primary cache stations Communicating and replicating data where it is needed.

  5. SAM as a Data Grid: Processing Stations Worldwide Lyon/IN2P3 100 MSU Abilene Prague 32 Columbia SURFnet ESnet NIKHEF 50 UTA 64 SuperJanet Fermilab Lancaster 200 Imperial College = MC production centers (#nodes all duals)
