  1. DØ MC Production DØ Production Iain Bertram 24 June 2004 Lancaster University

  2. MC Production • Introduction/Definitions • Production – Large Scale Processing • DØ will be treating data and MC processing in the same way. • Remote – Not Fermilab FarmNote: Could include Fermilab Farm (no reason not to) • Current Setup/Problems • Future Plans • Conclusions Iain Bertram

  3. Total MC Events Iain Bertram

  4. Events Per Week Iain Bertram

  5. Monte Carlo Production • Based on mc_runjob and request system • Documented @ MC Production Web Page • See Tutorial: http://www-d0.fnal.gov/computing/mcprod/Tutorial/index.html • All MC requests based on metadata • Request ID is main key • Request described by Metadata • Search for data based on request • Extendable – easily extend to new programs • Can be used for data reprocessing, large scale analysis jobs, etc. Iain Bertram

  6. Processing Schema • Current Running • Major improvements in memory and speed in p14 Iain Bertram

  7.

  8. Data/User Jobs Iain Bertram

  9. Data User/Jobs Instead of many jobs we have one job! Joins executables Iain Bertram

  10. Data: What is required • Not that much! • Already have option to turn on data processing • Choice of framework rcp available • E.g. Could process a selected J/Y sample with extended AA with simple flick of a switch. • Store pointer to framework rcp in metadata • Could add certification as standard processing step • What do we need: • Correct metadata storage • Merging Iain Bertram

  11. Production Problems • Manpower:Scalability • Requires 1 FTE at each site to run • Separate tools for reconstruction/MC • Problems running MC with SAM input • Queue run by me! • Software interoperability • mc_runjob/d0tools • running on virgin/clean machines • lightness and flexibility is needed • File Merging/Job Monitoring • Individual Jobs are not independent • No automatic job resubmission Iain Bertram

  12. Summary/Closing Remarks • Will Move to SAM-Grid ASAP • reduce manpower • Merge Data/MC Production • Simplify and separate components • Unified management • Runjob taken up by CMS • joint UK/DØ project • Rename Shahkar • CDF in future Iain Bertram
