Introductory and basic supply system for high performance computing for research and teaching

The bwUniCluster serves as the introductory, basic supply system for high-performance computing for research and teaching at universities in the state of Baden-Württemberg. It is financed by the state universities and the MWK and can be used by participating institutions based on their share of the funding.

The bwUniCluster is part of the Baden-Württemberg state concept for high-performance computing bwHPC and is operated by the Steinbuch Centre for Computing (SCC) of Karlsruhe Institute of Technology (KIT).

In addition to the bwUniCluster, the bwForClusters are available for specific scientific disciplines at several locations in the state - Heidelberg University, for example, hosts the bwForCluster MLS&WISO for the molecular life sciences and the economic and social sciences.
