Description
(For the CMS Collaboration)
Since CHEP04 in Interlaken, the CMS experiment has developed a baseline Computing
Model and a Technical Design for the computing system it expects to need in the first
years of LHC running. Significant attention was focused on the development of a data
model with heavy streaming at the level of the RAW data based on trigger physics
selections. We expect that this will allow maximum flexibility in the use of
distributed computing resources. The CMS distributed Computing Model includes a
Tier-0 centre at CERN, a CMS Analysis Facility at CERN, several Tier-1 centres
located at large regional computing centres, as well as many Tier-2 centres. The
workflows involving these centres have been identified, along with baseline
architectures for the data management. This presentation will describe the computing
and data model, give an overview of the technical design and describe the current
status of the CMS computing system.
