BwUniCluster3.0: Difference between revisions

Latest revision as of 14:29, 24 March 2026

The bwUniCluster 3.0+KIT-GFA-HPC 3 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 3.0 complements the four bwForClusters and their dedicated scientific areas.

SOLVED: Service Incident Notice: bwUniCluster 3.0 Login Not Possible

The login issue with bwUniCluster 3.0, which had been occurring since Friday, March 13, 2026, at 10:00 p.m., has been resolved.

The cause was a software error in the parallel file system, which has since been successfully corrected. A patch developed for us by the manufacturer has been applied. However, we would like to point out that we cannot currently completely rule out the possibility that the problem may recur under certain circumstances.

You can now log in as usual. Please check the results of your calculations and resubmit any jobs that were interrupted.

-== Changes ==
-Änderungen an Hardware, Quota
+The HPC cluster bwUniCluster 3.0 is the successor of bwUniCluster 2.0. It features accelerated and CPU-only nodes, with the host system of both node types consisting of classic x86 processor architectures.
-== Migration ==
+<br>
-Wie zieht man Daten um?
+To ensure that you can use the new system successfully and set up your working environment with ease, the following points should be noted.
+== Registration ==
-[[BwUniCluster3.0/Data_Migration_Guide|Data Migration Guide]]
+All users who already have an entitlement on bwUniCluster 2.0 are authorized to access bwUniCluster 3.0. The user only needs to '''register for the new service''' at https://bwidm.scc.kit.edu .
-|}
+== Changes ==
+Hardware, software and the operating system have been updated and adapted to the latest standards. We would like to draw your attention in particular to the changes in policy, which must also be taken into account.
+<br>
+Changes to hardware, software and policy can be looked up here: [[BwUniCluster3.0/Data_Migration_Guide#Summary_of_changes|Summary of Changes]]
+== Migration ==
+bwUniCluster 3.0 features a completely new file system. '''There is no automatic migration of user data!'''
+<br>
+The file systems of the old system and the login nodes will remain in operation for a period of '''3 months''' after the new system goes live (till July 6, 2025).
+<br>
+In order to move data that is still needed, user software, and user specific settings from the old HOME directory to the new HOME directory, or to new workspaces, instructions are provided here: [[BwUniCluster3.0/Data_Migration_Guide#Migration_of_Data|Data Migration Guide]]
