A preliminary list of the planned changes can be found [[BwUniCluster 2.0 Maintenance/2020-10|here]]. This list will be extended and specified in the next days and weeks. The biggest change will be the operating system version which will be updated from Red Hat Enterprise Linux 7.7 to version 8.2. |

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 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.
