The bwUniCluster 2.0 is the joint high-performance computer system of Baden-Württemberg's Universities and Universities of Applied Sciences for general purpose and teaching and located at the Steinbuch Centre for Computing (SCC) at Karlsruhe Institute of Technology (KIT). The bwUniCluster 2.0 complements the four bwForClusters and their dedicated scientific areas.

The following issue is known: Due to the hardware configuration, there is currently an already known problem with OpenMPI on the nodes in the "multiple_il" partition. It manifests itself in the warning "No OpenFabrics connection schemes reported" when starting an MPI application and refers to the device "mlx5_2". This is an Ethernet port, which is not supposed to be used by OpenMPI. The warning is informative, we are working on suppressing this message.
