CMS report for TSB meeting of 26th February 2004 Pedro Arce, 25 February 2004 We have already 18 million events simulated, up to 30 M foreseen in the next weeks. - 1 crash per 5000 events. - Also 3 Heavy Ion events (50k-80k primaries) in 1 job! For the next big production to start in summer '04 (around 100 M events): - Hunting crashes - Optimizing the memory and speed performance - Redesigning and checking in detail the geometry - Revisiting and optimizing the cuts - Automatizing the testing at each release of the main OSCAR components (geometry, generator, field, ....) as well as the GEANT4 physics
