Grid technology in production at DESY

DESY operates a complete and independent LCG-2 Grid infrastructure. It provides all services needed to run a Grid. Among the supported VOs are the global HERA VOs H1, ILC, and ZEUS, which are hosted at DESY, and the LHC VOs ATLAS and CMS. Since November 2004 the Grid infrastructure is used by the HERA VOs to produce Monte Carlo events at collaborating LCG sites.
