20:00 We are encountering several problems with the newly installed spack stack on a new file system share. We have just rolled back to the old file system. Apologies for any side effects. We will have to analyze the problem within the next days. The maintenance has mostly concluded. Please read https://www.lrz.de/aktuell/ali00938.html for details. |
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 problem with the software stack has been resolved. |
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. |
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
