Welcome to the DESY Grid pages. Some child pages are restricted () to logged in users.
Since 2004 DESY operates a Grid infrastructure and has participated in national and international Grid projects such as EGEE (2004-2010), D-GRID (2005-2009), and EGI / NGI-DE (since 2010). In 2006 DESY became a Tier-2 centre for ATLAS, CMS, and LHCb as part of the Worldwide LHC Computing Grid (WLCG). In the context of the Physics at the Terascale project DESY operates the National Analysis Facility (NAF) which complements the Grid with interactive computing resources.
The DESY Grid infrastructure provides federated computing and storage resources for the WLCG virtual organizations (VO) 'atlas', 'cms', and 'lhcb', hosts the global VOs 'ghep', 'hermes', 'hone', 'icecube', 'ilc', 'ildg', 'xfel.eu', and 'zeus'., and supports 'belle'.
In order to equip DESY and U Hamburg users with Grid user certificates, a registration authority (RA) serving the German certification authority (CA) at GridKa in Karlsruhe is available.
The global entry point for Users in the Grid is the Global Grid User Support (GGUS).
