About Scientific Computing Center

The Scientific Computing Center (SCC) is the information technology center of KIT. The SCC not only provides IT services for a big research institution, but also SCC does research in the topics of scientific computing and data analysis, management of large scale research data and data intensive computing as well as secure IT-federations.

On behalf of the State of Baden-Württemberg and as a member of the Nation High Performance Computing Alliance (NHR), SCC runs a Tier-2 high performance computing system (HoreKa) for nationwide users with focus on Energy, Mobility and Environmental research, the Earth System or Material sciences. The Petaflop system is very energy-efficient and it works through a ‘hot-water cooling’ which won the first place at the ‘Deutscher Rechenzentrumspreis’ 2017.

Furthermore SCC provides the joint high-performance computer system of Baden-Württemberg's Universities and Universities of Applied Sciences for general purpose and teaching, i.e., bwUniCluster 2.0. For the international high-energy physics community, the SCC operates a German WLCG-Tier-1 data and analysis center with GridKa for storing, analyzing and archiving the data of the LHC-accelerator at CERN.
