The LHC Computing Challenge

CERN's Large Hadron Collider turns on next year, providing high-energy particle collisions for four experiments that, between them, are expected to generate up to 15PB of data per year. After giving a brief introduction to the accelerator and experiments, this talk will outline the associated computing challenges—in particular, cluster management, data storage and distribution, and grid computing—and describe how CERN and the worldwide particle physics community have been preparing to meet them.
