Höchstleistungsrechenzentrum Stuttgart: GENE/GENE-X user training and tutorial

Prerequisites and content levels

Prerequisites:

Participants are expected to have basic skills in Unix-based operating systems, including navigating terminals and using SSH, as well as some familiarity with text editors such as vi/emacs. Knowledge of compiling code is helpful but not strictly necessary.
Additionally, participants should have a basic understanding of Python, as it is required for both preprocessing and post-processing simulation in- and output.
To participate in the program, individuals preferably have their own account on a cluster or supercomputer where the GENE and/or GENE-X codes can be installed. It is recommended that participants contact the organizers beforehand to confirm that their cluster is suited for this workshop and to clarify any questions they may have. Finally, participants should have a small budget (few kCPUh) allocated on a cluster to perform code verification tests and hands-on submissions of small test jobs.
- For EU residents it is possible to get a workshop account on Leonardo Booster at CINECA through ENCCS and SIDE. Please indicate the necessity in the registration form. A short basic introductory course can be attended online on Monday morning, where working on Leonardo Booster is introduced.

Content levels:

Advanced: 27 hours 45 minutes

Registration information

Register via the button at the top of this page.
This course will be hybrid, i.e. it will take place at the Max Planck Computing & Data Facility (MPCDF) in Garching on-site but it will also be possible to attend online. Participants, online as well as on-site, have to be aware and agree that they might appear in the live video stream taken by a camera in the back of the lecture room or by a webcam on laptops. We strongly recommend to attend this course on-site since on-site attendance is much more effective and efficient in our experience, also this helps to foster collaborations and community-building. Therefore we might give priority to on-site over online participants during registration.

Please be aware that the Zoom session will be recorded. You declare that you are aware of and consent to the recording by registering.

Registration closes on Monday, 5 January 2026.

Fees

Students without Master's degree or equivalent. Participants from EU or EuroCC countries only: 0 EUR
PhD students or employees at a German university or public research institute: 0 EUR
PhD students or employees at a university or public research institute in an EU or EuroCC country other than Germany: 0 EUR.
Other participants, e.g., from industry, other public service providers, or government. Participants from EU or EuroCC countries only: 0 EUR

Our course fee includes coffee breaks (in classroom courses only).

For lists of EU and EuroCC countries have a look at the Horizon Europe and EuroCC website.
