RWTH High Performance Computing (HPC)

In order to mitigate a security vulnerability, network namespaces have been disabled on the cluster. This impacts several software packages on the cluster which may not work properly as a result. This includes browsers such as Firefox, Chrome/Chromium and by extension electron-based software (e.g., VSCode) as well as all other programs that utilize network namespaces internally (e.g., ANSYS workbench). Since the network namespace feature has been the gateway for several high-severity vulnerabilities in the past and the common mitigations we have been forced to implement have unsatisfying side-effects, we are working on rolling out a custom solution to allow finer restrictions in the future. We apologize for the inconvenience.

Network Namespaces have been successfully reactivated following the introduction of a fix. We are currently running this solution in a test phase.

Although the namespaces are active again, issues may still occur. We are closely monitoring the situation and will provide further updates if needed.

Due to external power outages in Aachen, Slurm Jobs or interactive sessions might have experienced issues during this time period.

Submission to specific Slurm projects fails currently due to NFS Filesystem issues that make certain system files unreadable.
We are currently investigating the issue and working on a solution.

We manage to solve the issue and submission should work properly now.

Am 06.03. führen wir von 7-18 Uhr eine Systemwartung durch.
Der komplette Cluster wird während der Wartung nicht verfügbar sein.

The maintenance has been completed.
