New version of the RWTH Person Directory and RWTHcontacts. Just like in the RWTH Directory of Organizations, buildings and addresses can be selected using the RWTH building management system. Selected buildings are linked to the RWTH Navigator in RWTHcontacts.
Resource limits on HPC dialog systems changed
We have reduced the per-user-resource limits for main memory on the HPC dialog systems (login18-1.hpc.itc.rwth-aachen.de etc.). A single user can now only use about 25% of the available main memory, i.e. 96GB for most of our servers. On login18-x-1 and login18-x-2, as before, only 16 GB are available to each user.
Release Notes Version 2.3.0
Improvements and bug fixes:
- Toasts for notifications have been improved, e.g., after deleting favorites, so that you can now “hold” them and they do not disappear immediately
- If you go to a page such as the calendar without being logged in to the app (without SSO login), you will now be redirected back to that page after completing the login process (previously, you were redirected to the dashboard).
- In Moodle:
- for assessments, the maximum achiveable score is now also displayed
- in the download center, labels were previously displayed as files that could be downloaded; this was not desired and they are no longer displayed.
- Minor color adjustments
- Minor bug fixes, e.g., when displaying the loading animation.
Changes to Abaqus Batch Jobs
Today, we have made several major changes to the Abaqus configuration on the RWTH-HPC systems. These changes include an automatic configuration of many batch job parameters which previously have been generated on-the-fly as part of the example batch script we described in Abaqus documentation .
With this new setup, users should experience less problems when starting Abaqus batch jobs and receive descriptive error messages including suggested solutions when something goes wrong during configuration. These changes only affect Abaqus 2020 and newer.
Do I need to change my batch scripts?
No. The previous example batch scripts still work. However, you may omit the part that generates a local abaqus_v6.env file. If such a file exists in the job’s working directory, its settings will override the system settings but in most cases these are identical as of now.
What to do if I experience problems?
If you have trouble running the Abaqus GUI on a frontend node, please make sure to delete the abaqus_v6.env file from the working directory. Alternatively, you can try starting the GUI from another directory. If you still experience problems or if your batch jobs behave in an unexpected fashion, please report the issue to servicedesk@itc.rwth-aachen.de
OS Upgrade to Rocky 8.8
Dear users of the cluster,
on
** July 17, 2023 from 7:00 a.m. to 5:00 p.m. **
there will be a maintenance where we will update the current operating system Rocky Linux 8.7 to Rocky Linux 8.8. The front ends will also be updated, so you will not be able to log into the cluster or access your data.
However, there is an exception to this. The MFA test engine login18-4 will remain accessible, but you will only be able to log in there with a second factor [1]. Temporarily, however, $HPCWORK will also be unreachable here, as the Lustre file system is also undergoing maintenance.
We do not expect that you will have to recompile your software or change your job scripts. So your jobs should start normally after the end of the maintenance.
With best regards
Your HPC Team @ RWTH

Name change for TURBOMOLE modules
Previously, we offered TURBOMOLE modules unter the name of turbomolex to designate the availability of the TmoleX GUI. To conform with our new naming scheme which takes the software developers/vendors’ branding into account and to avoid unnecessary confusion, we have decided to rename this module to TURBOMOLE.
We will support the old module name for some time to give users enough time to adjust and to prevent disruptions.
