Experience of MonteCarlo simulations for a LEP experiment on UNIX
M.Bonesini, A.Calegari and V.Rossi
The production of Monte Carlo simulated events has become a major challenge
for large HEP experiments. The complexities of the detectors pose severe
difficulties in keeping a high pace of production together with the
required accuracy in simulating the detector.
simulation program (DELSIM), the only one in LEP not using GEANT,
is tipical in this respect.
A long term collaboration between the
group in Milan and CILEA
Computing Centre, started in 1990, has proved to be effective in providing
high production rates at low costs.
Since 1991 we have been trying different distributed computing environment
with different organizative models.
At present the production chain is running on a mixed
supercomputer-workstations environment with a peak production rate
of more than 10K events/day.
