Description
Experiments at the Large Hadron Collider (LHC) have been collecting data over more than a decade and meanwhile crossed the Exabyte line. The data is processed on about 170 data centres, which are spread over the member states and form the Worldwide LHC Computing Grid (WLCG). The Göttingen campus hosts the WLCG Tier-2 centre GoeGrid, founded in 2008, and takes part in fulfilling the German resource pledges given to the LHC collaborations.
The upcoming High-Luminosity-LHC with ten times higher data rates and the need for more and also sustainable compute resources are challenging and triggered transformations at many points in the data processing chain, e.g. data formats, data management, software, resource provision etc. In Germany, the university-based WLCG Tier-2 centres will be replaced by centralised storage at the Helmholtz Centres DESY and KIT and compute power provided by three NHR centres (National High Performance Computing). Göttingen is the location of one of these NHR centres and hence remains in the role of a WLCG Tier-2 site with increasing responsibility. An overview of the WLCG activities with a local focus on Göttingen will be presented.
