1 Forschungszentrum Karlsruhe: GridKa and GGUS Forschungszentrum Karlsruhe GmbH Institute for Scientific omputing P.O. Box 3640 D Karlsruhe, Germany Holger Marten (for the GridKa and GGUS teams)

2 The Grid omputing entre Karlsruhe GridKa Requested as a Regional Data and omputing entre by 41 HEP user groups in 19 German universities and research institutions. Founded in 2001 as part of the computing centre of Forschungszentrum Karlsruhe. Main goals test environment for LH (ALIE, ATLAS, MS, LHb) LH Tier-1 in production environment for non-lh (BaBar, DF, D0, ompass) environment for Grid R&D (rossgrid, LG, EGEE, ) user support, services, education & training grid environment for other sciences (astrophysics, bio-informatics...)

3 High Energy Physics experiments served by GridKa Atlas (SLA, USA) (FNAL,USA) ommitted to Grid omputing Have real data already today (FNAL,USA) (ERN) LH experiments non-lh experiments Other sciences later
