Messages for all HPC System

The new ANSYS Release 2025.R2 has been installed, tested and rolled-out on SuperMUC-NG Phase 1 and CoolMUC-4. ANSYS 2025.R2 has been made the new default ANSYS Release on those systems and the LRZ documentation has been updated in due course.
In case of any related observations, please file an LRZ Service Request. The LRZ download portal for the ANSYS software will be updated with the new ANSYS installation files asap.
It might be worth mentioning, that with ANSYS Release 2025.R2 the Rocky DEM solver is supporting for the first time SuSE Linux Enterprise Server operating system, i.e. SLES 15 SP4,5,6.

The new Siemens PLM Release of StarCCM+ 2025.2.1 (= 2506.0001 = v20.04.008) has been installed, tested and rolled-out on SuperMUC-NG Phase 1 and CoolMUC-4. StarCCM+ 2025.2.1 has been made the new default StarCCM+ Release on those systems and the LRZ documentation has been updated in due course. At the same time the old StarCCM+ versions 2023.x.1, x=1,2,3 have been deprecated and removed from the LRZ HPC systems.
In case of any related observations, please file an LRZ Service Request.

Phase 2: Start of user operation

Start of user operation has been anounced. All SuperMUC-NG Phase 1 projects can now access Phase 2 as well and have an initial budget of 900 GPU hours for testing. In the startup phase of user operation, we will only bill 25% of the actual compute time used. This factor will be gradually increased to 100% over the next few months; changes will be announced in a timely fashion. 

Regular compute time applications requesting resources on Phase 2 can now be submitted via the GCS-JARDS portal

https://jards.gauss-centre.eu/gcshome/

and a GCS Large Scale Call is coming up in July.

New quick reference. The first release of the CoolMUC Cheat Sheet has been published.

Messages for Compute Cloud and other HPC Systems

The AI Systems (including the BayernKI and MCML system segments) will undergo a maintenance procedure between September 8th and 10th, 2025. On these days, the system will not be available to users. Normal user operation is expected to resume during the course of Wednesday, September 10th.

The LRZ AI Systems have to undergo a short maintenance early next week. For this, the system will be drained over the weekend and start-up of new jobs will be delayed until after the maintenance. We expect the actual downtime to not exceed more than 10 minutes.

The AI Systems (including the BayernKI and MCML system segments) will undergo a maintenance procedure between May 19th and 21st, 2025. On these days, the system will not be available to users. Normal user operation is expected to resume during the course of Wednesday, May 21st.
