Description
In preparation for the start of the experiment, CMS must produce large quantities of
detailed full-detector simulation. In this presentation we will present the
experiencing with running official CMS Monte Carlo simulation on distributed
computing resources. We will present the implementation used to generate events using
the LHC Computing Grid (LCG-2) resources in Europe, as well as the implementation
using the Open Science Grid (OSG) resources in the U.S.. Novel approaches have been
deployed that make it possible to run the full CMS production chain on distributed
computing resources from the generation of events, to the publication of data
for analysis, including all the intermediate steps. The CMS transfer system has been
coupled to the LCG production chain to make the tools more robust and significantly
improving the performance of the production in LCG. The CMS production has been
running on LCG-2 and OSG for several months and an analysis of performance and
operational experience will be presented.
