The CMS Computing System: Successes and Challenges
K. Bloom · arXiv (Cornell University) · 2009
Each LHC experiment will produce datasets with sizes of order one petabyte per year. All of this data must be stored, processed, transferred, simulated and analyzed, which requires a computing system of a larger scale than ever mounted for any particle physics experiment, and possibly for any enterprise in the world. I discuss how CMS has chosen to address these challenges, focusing on recent tests of the system that demonstrate the experiment's readiness for producing physics results with the first LHC data.
