Description
DESY is one of the world-wide leading centers for research with particle accelerators
and a center for research with synchrotron light. The hadron-electron collider HERA
houses four experiments which are taking data and will be operated until mid 2007.
DESY has been operating a LCG-based Grid infrastructure since 2004 which was set up
in the context of the EU e-science Project EGEE.
The HERA experiments H1 and ZEUS as well as the International Linear Collider (ILC)
community have started to massively use the Grid for Monte Carlo production. For
those groups, Virtual Organizations (VO) are hosted at DESY, including all necessary
Grid services. These global VOs are meanwhile supported by many international LCG sites.
DESY currently plans for a participation in one of the LHC experiments ATLAS or CMS.
It has been already decided that DESY will become an LCG Tier-2 center for both
experiments. The Tier-2 activities will be merged with the Grid infrastructure in
operation.
In the contribution to CHEP2006 we will give an overview of the Grid infrastructure
and discuss deployment and operational aspects. Main emphasis will be put on the
details of the set-up of a complete production-grade Grid with all services and its
integration into a computer center infrastructure with regard to the Tier-2 plans at
DESY.
