Experience with CMS offline and computing in LHC runs 2010-2011
Jean-Roch Vlimant · Proceedings of XXIst International Europhysics Conference on High Energy Physics — PoS(EPS-HEP2011) · 2012
In this presentation we will discuss the experience with the CMS computing model during the LHC runs 2010-2011.We will outline how the experiment operations has evolved during the first few months of operations.The current state of the Offline and Computing projects will be presented and we will describe the initial experience with active analysis users and real data.We will include Tier-0 processing, reprocessing steps on data and fast turn-around calibrations.We will address the issues that worked well in addition to identifying areas where future development and refinement are needed.
