- Event reconstruction 7x104 SPECint95
- 250 SPECint95-sec/event = 10xFermilab
- Monte Carlo production 5x104 SPECint95
- 10% of number of real events
- Physics analysis 15x104 SPECint95
- 20 analysis groups
- 25 people in each group => 500 people analysing
- 150 simultaneous users
- group loops over 109 events/month - selecting 1-10%
- each physicist loops over selected events 1/month
- each physicist loops over AOD/Ntuple 1/day
1 SPECint95 = 40 SPECint92 = 10 CERN units = 40 MIPS
