The Compact Muon Solenoid (CMS) experiment is a general-purpose particle physics experiment. Designed to see a wide range of particles and phenomena produced in LHC collisions, each involves approximately 2,000 physicists from more than 30 countries. These scientists will use the data collected from the complex CMS detector to search for new phenomena including the Higgs boson, supersymmetry, and extra dimensions. They will also measure the properties of previously- discovered quarks and bosons with unprecedented precision, and be on the lookout for completely new, unpredicted phenomena.
CMS is using a globally distributed computing model. The data is processed first at CERN and then transferred to the regional Tier-1 data centers around the world. The Tier-1 centers then skim the data for physics signals and provide them to Tier-2 centers. The Computing Sector has built the largest CMS Tier-1 center in the world which is mission critical to the CMS experiment.
The Computing Sector provides state of the art computing, networking, and storage solutions to tackle the challenge of the massive data transfer, data archiving, and data processing required by CMS. Equally important to CMS is the strong pool of development and support effort provided by the Computing Sector that CMS has been able to draw upon to contribute to the development of the CMS software framework, the CMS workflow and data management systems.
