as part of the recent maintenance, we shifted the software stack to a new filesystem. Yesterday, during the late afternoon a degradation occurred that led to segfaulting of applications. The root cause is still under investigation.
As a temporary remedy, we switched back to the software stack on the previous filesystem yesterday evening (May 19). Today, we confirmed that most applications seem to work well.
We will keep you informed about the progress to a complete solution of the problem.
Apologies for any inconveniences.
The maintenance has mostly concluded. Please read https://www.lrz.de/aktuell/
| the announcement of the next SuperMUC-NG maintenance on 5.-6 May 2020. The following block operation for very large jobs will be conducted in the 48h after the maintenance. |
Since we are experiencing network-related problems on CoolMUC-2!
We will need to reboot the system on the morning of . Jobs will be flushed from the system before the reboot is initiated.
If you encounter problems, please see: CoolMUC-2: Open issues after the Cluster Hardware and Software Upgrade (Linux Cluster Maintenance on 17.-25. March 2020).
On Monday, April 4, 2022, a new version of the spack-based development and application software stack will be rolled out.
The new spack version will be loaded as default starting April 11, 2022
After that date, you will be still able to switch to the previous spack stack with
> module switch spack spack/21.1.1
We strongly recommend recompiling self-built applications after the roll-out. See also https://doku.lrz.de/display/PUBLIC/Spack+Modules+Release+22.2.1 for details.
Base core frequency of jobs has been set to 2.3GHz. Higher frequencies possible using EAR.
The new hpcreport tool is now available to check job performance and accounting on SuperMUC-NG. Please check out

We have observed and addressed an issue with the LRZ AI Systems that concerned some running user jobs. As of now, newly started jobs should not be affected anymore.
The work on the LRZ AI Systems to address the recently observed stability issues has been concluded. All users are invited to continue their work. We closely monitor system operation and will provide additional updates if needed. Thank you for your patience and understanding.
We have identified the likely root cause for the ongoing issues with the LRZ AI and MCML Systems following the latest maintenance downtime. We continue work towards a timely resolution and can currently not guarantee uninterrupted & stable system availability. For further details, please see LRZ AI Systems
