bwUniCluster 3.0
The bwUniCluster 3.0 is the shared general-purpose HPC system of the universities and universities of applied sciences in Baden-Württemberg. It is located at the Scientific Computing Center (SCC) of the Karlsruhe Institute of Technology (KIT).
The bwUniCluster complements the field-specific bwForClusters and serves as the entry-level system for HPC in research and teaching. All researchers and students at Baden-Württemberg universities can use it free of charge — no project proposal required.
In operation since April 2025. Over 370 nodes connected via fast InfiniBand. OS: Red Hat Enterprise Linux 9.
