Description
The upgrades of the Tevatron collider and of the CDF detector have considerably
increased the demand on computing resources in particular for Monte Carlo production
for
the CDF experiment. This has forced the collaboration to move beyond the usage of
dedicated resources and start exploiting Grid resources.
The CDF Analysis Farm (CAF) model has been reimplemented into
LcgCAF in order to access Grid resources by using the LCG/EGEE Middleware components.
Many sites in Italy and in Europe are accessed via this portal in order to produce
Monte Carlo data
and in one year of operations we expect about 100,000 Grid jobs submitted by the CDF
users.
We review here the setup used to submit jobs to Grid sites and retrieve the output,
including the Grid components CDF-specific configuration.
The batch and interactive monitor tools developed to allow users to verify the jobs
status during theirs lifetimes in the Grid environment are described.
We analyze the efficiency and typical failure modes of the current Grid
infrastructure reporting
the performances of different parts of the used system.
