CERN, from an IT Perspective
summary
CERN runs the 27 km Large Hadron Collider that accelerates protons to 7 TeV and 99.9999991% of light speed, sending ~3,000 bunches (≈100 billion protons each) around 11,000 times per second; detectors see ~600 million collisions/s and a single detector produces ~2 PB/s raw data, so GRID distribution and filtering keep about one in a million events. On-site IT: 166,000 cores, 150 PB disk, 240 PB tape, ~50 PB/year ingested; Java and Java3D visualisations power control and outreach tools; the LHC Computing Grid runs ~2 million concurrent jobs as a planetary supercomputer.
