bwForCluster NEMO

Research Cluster for Neuroscience, Elementary Particle Physics, Microsystems Engineering and Materials Science (NEMO)

Security Shutdown - Login Disabled

Published: 8 Jul 2026 by NEMO2 Team

Multiple security vulnerabilities currently exist for which exploit code is already available. To prevent misuse, we are forced to shut down login access.
Jobs that are already running will not be terminated and continue to run as normal. The cluster itself keeps running; only login is not possible until the security issues have been resolved.
We hope to restore login access by Friday, July 17th.
If you have any questions, please contact the NEMO2 team.

MathWorks Products: No General License Available on NEMO2

The statewide academic license agreement for MathWorks products at Baden-Württemberg universities expires on March 31, 2026. There will be no general MathWorks license available on NEMO2 specifically. Universities and other clusters may handle this differently. Please consider using open-source alternatives or contact us if you hold your own license.

SSH Configuration Issue Fixed: Local Authorized Keys No Longer Working

An SSH configuration issue on the login nodes has been fixed. SSH keys stored in local authorized_keys files are no longer accepted. This behavior was never intended - please use SSH keys configured in login.bwidm.de instead.
