-

The Compute Cloud will be shut down due to a planned power outage on Tue afternoon, February 2nd. Operation is expected to resume Friday, February 5th, 2021. For further details, please see here.

This downtime will also affect RStudio Server Please note that the CPU frequency on all nodes has been lowered from 2.7 to 2.3 GHz, to reduce the energy consumption. EAR is currently not active, so job execution times are expected to rise somewhat.
Messages for SuperMUC-NG

Due to the job processing backlog and the current job profile, no reservations or priorizations can be granted.

A maintenance has been scheduled for February 1-5. See details.

Messages for Linux Cluster

Please see the upcoming Online Courses and Workshops provided by LRZ.

The new version 2021 of Abaqus (FEM software by Dassault Systems) has been installed on Linux Clusters which are running SLES15 operatig system (i.e. CM2 and CM2_tiny). New corresponding module files are provided. The new version abaqus/2021 has been made the new default Abaqus module.

Due to the very limited use of MSC products or MSC Licenses on High-Performance Systems at LRZ, the MSC software support including installations and license server will be taken off by September 2021. Please do write us a ticket if you want to communicate on this matter with a subject MSC via https://servicedesk.lrz.de/.

The announced maintenance interval has been somewhat shifted to the time frame February 3-5. Please read the details on the impact for the different cluster segments.

Archive nodes update
The  hardware maintenance has been rescheduled. Please expect a short downtime of the archive and backup servers (IBM spectrum protect) from 09:00 to 11:00 o’clock on Monday 24.01.22 .

 The new ANSYS Software Release, Version 2022.R1 has been installed and provided on SuperMUC-NG. For details please refer to the correspondig announcement:
https://www.lrz.de/aktuell/ali00931.html

The Energy Aware Runtime (EAR) has been reactivated. Please be aware that this may have an impact on job processing times.

Please note that WORK/SRATCH on SuperMUC-NG exhibit currently possible performance degradation under heavy I/O load. Take this into account when planning your job runtimes.

The new hpcreport tool is now available to check job performance and accounting on SuperMUC-NG. Please check out

Messages for Linux Clusters

SCRATCH is now fully online again. While we expect older data that were temporarily inaccessible to be fully available again, data that were created in the last few days before the problems started might be corrupt and need to be renewed from tape archive (if one exists) or recreated. 
There will be a reboot of one servers tomorrow, which however should not impact overall system operation.

The new ANSYS Software Release, Version 2022.R1 has been installed and provided on the LRZ Linux Cluster systems (CM2, CM3 and RVS systems). For details please refer to the correspondig announcement:
https://www.lrz.de/aktuell/ali00931.html

The new release of Abaqus, Version 2022 (Dassault Systems Software) has been installed on both Linux Clusters CoolMUC-2 / CoolMUC-3 as well as on the RVS systems. The Abaqus documentation has been updated.

The new release of SimCenter StarCCM+, Version 2021.3.1 (Siemens PLM Software) has been installed and provided on the LRZ HPC systems (CM2, CM3, SNG and RVS systems). For details please see the correspondig announcement:
https://www.lrz.de/aktuell/ali00927.html

There are 4 new Remote Visualization (RVS_2021) nodes available in a friendly user testing period. Nodes are operated under Ubuntu OS and NoMachine. For more details please refer to the documentation.



Messages for Cloud and other HPC Systems
