Grid computer farm. Technician wheeling stacks of discs through banks of computers forming part of a 'PC farm' at CERN, the European Particle Physics laboratory near Geneva, Switzerland. They are being prepared to accept and analyse data from the new Large Hadron Collider (LHC). The LHC will smash particles together in an effort to find their constituents, and will generate millions of gigabytes of data. This is also being used as a test run for The Grid, a network of computers that can share processing power. This means that a standard desktop computer connected to The Grid can be used to perform powerful calculations.
