Abstract:
In preparation for first data at the LHC, a series of Data
Challenges, of increasing scale and complexity, have been
performed. Large quantities of simulated data have been
produced on three different Grids, integrated into the ATLAS
production system. During 2006, the emphasis moved
towards providing stable continuous production, as is required
in the immediate run-up to first data, and thereafter.
Here, we discuss the experience of the production done
on EGEE resources, using submission based on the gLite
WMS, CondorG and a system using Condor Glide-ins. The
overall walltime efficiency of around 90% is largely independent
of the submission method, and the dominant source
of wasted cpu comes from data handling issues. The efficiency
of grid job submission is significantly worse than
this, and the glide-in method benefits greatly from factorising
this out.
