Cables connect server racks in the computer center of the Cern, the European Organization for Nuclear Research, near Geneva, on Thursday, Oct. 2, 2008. CERN’s in house computer farm will provide only a small percentage of the processor power that is needed to analyze the huge data that the Large Hadron Collider experiment will collect. The rest of the data will be processed with a computer grid, concentrating the calculating power of more that 100 research institutions worldwide.
