Spring 2002 CMS Monte Carlo Production: what? how? and what next?

Veronique Lefebure, Helsinki Institute of Physics

Abstract

During the first four months of 2002, the CMS Monte Carlo Production team has produced about 20 TB of data for the preparation of the DAQ TDR [data acquisition technical design report]. It included the simulation of primary proton-proton interactions, secondary interactions in the detector, response of the sensitive elements, pile-up of events, and first-pass analysis. The data was written into Objectivity/DB ODBMS. This was a world-wide production involving more than 30 persons and 20 sites.

This seminar presents the full machinery of this successful Monte Carlo production and describes what worked and what didn't. Some first thoughts will also be presented on how to improve the system for the coming major production preceding the 2004 data challenge.

About the speaker: Veronique Lefebure got her Physics PhD from Brussels University in 1997, working in the DELPHI experiment. Then she was a CERN fellow for two years, in CMS/CMC group, working on ORCA for the object-oriented simulation of the MSGC detectors, and also on test-beam simulations with GEANT4. After that she worked for 4 months for ESA in the CERN/IT division, developing the Low Energy Electromagnetic Interaction physics package. She then rejoined the CMS/CMC group where she started to work as MC Production Coordinator under a project associateship contract with Helsinki Institute of Physics.
