On 17.03.2020, the Steinbuch Centre for Computing (SCC) at Karlsruhe Institute of Technology (KIT) commissioned a new parallel computer system called "bwUniCluster 2.0+GFB-HPC" as a state service within the bwHPC framework. The bwUniCluster 2.0 replaces the predecessor system [[:Category:BwUniCluster | bwUniCluster]] and also includes the additional compute nodes which were procured as an extension to the bwUniCluster in November 2016.

The modern bwUniCluster 2.0 system consists of more than 840 SMP nodes with 64-bit Intel Xeon processors. It provides the universities of the state of Baden-Württemberg with general compute resources and can be used free of charge by the staff of all universities in Baden-Württemberg. Users who currently have access to bwUniCluster will automatically also have access to bwUniCluster 2.0. There is no need to apply for new entitlements or to re-register.

bwUniCluster2.0


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.
Next maintenance

Due to regular maintenance work the HPC System bwUnicluster 2 will not be available from

20.03.2023 at 08:30 AM until 24.03.2023 at 15:00 AM

Please see the maintenance page for more information about planned upgrades and other changes
