Central data processing room computers and machines at CERN, the European particle physics laboratory near Geneva, Switzerland. CERN's computing centre has 17,000 processors with 85,000 computing cores, as well as computer tape and disk storage capacity for over 200 petabytes of data. It is part of the Worldwide LHC Computing Grid (WLCG), a global computing network that stores, distributes and analyses data from CERN's Large Hadron Collider (LHC). The LHC, the world's largest and most powerful particle collider, began operating in 2008. Photographed in October 2006.
