Transition bwUniCluster 2.0 → bwUniCluster 3.0

The HPC cluster bwUniCluster 3.0 is the successor to bwUniCluster 2.0 and will go into operation on April 7, 2025.

The new bwUniCluster 3.0 is a hot water-cooled system that will be operated at KIT Campus North. The cooling process achieves a significantly more efficient and energy-saving cooling of the computer system compared to the previous system.

Please note: bwUniCluster 3.0 will be equipped with a new file system for HOME and workspaces. An automatic migration of your data to the new system will not take place. We will provide detailed instructions on how to migrate data. Bash scripts will also be available with which you can initiate the migration.

The file systems and the login nodes of the old system will remain in operation for a period of 3 months after the new system goes live. This leaves enough time to copy any data to be migrated from the HOME directory and the workspaces to the new file systems.

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 Scientific Computing Center (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.

-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.
