Presentation Transcript

  1. First attempt at using WIRED Eric van Herwijnen

  2. Overview • Gaudi MC event server • Tracking group’s reconstructed events • Test version released • Future plans

  3. /run1/event1.xml /event2.xml /....... /run2/event1.xml /event2.xml /..... /....../...... Eventx.xml WIRED EventDumpAlgorithm http://lhcb.cern.ch:8080/servlets/eventselector&runx#eventy (Gaudi) Sicb dataset

  4. Open an MC event from Web server

  5. Production plans

  6. Status of simulated event production • 180 k mbias events • 270 k bb inclusive • 7*106 total number of events simulated so far ( 1 TB data)

  7. Current capacity • Production centers for simulation: • No dedicated LHCb facility • CERN CSF (being phased out for us) • RAL CSF • IN2P3 • Heidelberg • For analysis: • CERN RSBATCH/RSPLUS (being phased out for us)

  8. New production centers • CERN- Planned by end 1999: • CSF PCSF (first production 300k events done for new magnet study, 150 k events/week) • RSBATCH  Linux cluster (analysis batch) • RSPLUS  LXTEST (interactive logon service) • LHCb LSF cluster (corridor PC’s, 50 LHCb machines available,  75 k events/week)

  9. New production centers • Outside CERN (figures for v116/117): • Liverpool ( 50 times PCSF, 7500 k events/week) • RAL PC farm (half the size of PCSF, ie  75 k events/week) • RAL CSF ( 10 k events/week) • Lyon IN2P3 ( 20 k events/week) • RIO Linux farm (?)

  10. SICB performance

  11. Test release • Http://lhcb.cern.ch/computing/analysis/default.htm • Download the file install.class • Install jdk 1.1.8 (from IBM) for best preformance • Type java install

  12. Future work • Make an XML conversion service instead of an algorithm • Re-arrange hits & reconstructed tracks • Improve interactivity • Get feedback
