Description
The detector and collider upgrades for the HERA-II running at DESY have considerably
increased the demand on computing resources for the ZEUS experiment.
To meet the demand, ZEUS commissioned an automated Monte Carlo(MC) production capable
of using Grid resources in November 2004. Since then, more than one billion events
have been simulated and reconstructed on the Grid which corresponds to two thirds of
the overall MC production in this period.
Based on the experience gained in this successful and efficient production on the
Grid, a system has been developed for also running analysis jobs on the Grid. It
allows standard ZEUS executables to be submitted to the Grid without any changes and
with similar commands as used for the batch analysis. With this approach, the users
can easily switch to running their analyses on the Grid and benefit from the
additional resources without any Grid middleware knowledge.
We present the design and implementation of the Monte Carlo production
and the analysis systems which are both based on the ZEUS Grid-toolkit. Furthermore,
we report on the status of these systems and our experience with large scale
production on the Grid.
