Date: Thursday, June 11, from 8:30 am (CEST) to June 12, 2026 afternoon.
Venue: Leibniz Supercomputing Centre (LRZ), Boltzmannstr. 1, 85748 Garching bei München, Germany.
In celebration of 20 years of SeisSol and 10 years of ExaHyPE, we are happy to announce
- The first Joint SeisSol+ExaHyPE User Workshop,
- A combined SeisSol+ExaHyPE User Training,
- The first SeisSol+ExaHyPE Hackathon,
taking place on June 11-12, 2026 in Garching (Munich), canvat the Leibniz Supercomputing Centre (LRZ).
Organizers: Michael Bader (TUM) Alice-Agnes Gabriel (LMU, Scripps), Tobias Weinzierl (Durham University)
Geo-INQUIRE Installation: SeisSol/ExaHyPE virtual access (VA4-531-1) and transnational access (TA2-531-1).
Speakers: For the user workshop (June 11), we call for contributed talks on usage and development of SeisSol or ExaHyPE, and closely related topics. If you are interested in contributing, please add the title of your talk in the registration form.
Event type: on-site. Parts of the program may be made available via streaming or recordings.
Preliminary program:
- Thursday: User meeting with scientific talks
- Thursday evening: Social dinner
- Friday morning: User training (general introduction) SeisSol and ExaHyPE
- Friday afternoon: Hands-on sessions/Hackathon
Target audience: The user training and hackathon (June 12) addresses new/potential and existing users of SeisSol and ExaHyPE. We will offer (partly parallel) tracks on:
- Solving hyperbolic PDE systems with high-order discontinuous Galerkin methods using SeisSol and ExaHyPE
- Earthquake simulations with SeisSol
- ExaHyPE use cases from seismology to relativistic astrophysics
- Performing seismic simulations with SeisSol (hands-on session)
- How to implement your own hyperbolic PDE solver in ExaHyPE (hands-on session)
Existing and more experienced users of SeisSol and ExaHyPE are invited to discuss issues of usage, optimisation, and further development of SeisSol and ExaHyPE during our Hackathon session on June 12.
Prerequisites: To attend the SeisSol training on Friday, basic Linux user-level skills are enough; for the ExaHyPE training, Python and C++ skills are required. Please bring your own laptops.
Maximum number of participants: The Friday training sessions are limited to ~30 participants. Please specify which training or hackathon you would like to attend in the registration form.

Logistics:
- Workshop fee:
We ask for a contribution of 60€ to cover meals. This includes lunch and the social dinner on Thursday, a Bavarian “Weißwurstfrühstück” on Friday, and coffee breaks.
- Accommodation:
Please book your accommodation individually. There are several hotels in Garching or Ismaning, or in northern Munich along the U6 subway line. The Courtyard by Marriott and Stellaris Apartment Hotel Garching are directly on campus.
- Transportation to/from the venue:
The Leibniz Supercomputing Centre is located close to the subway station “U6 Garching-Forschungszentrum”. From Munich main station, you will need ~45 Minutes to reach LRZ by S- and U-Bahn (transfer at Marienplatz). From the airport, take the S8 and alight at Ismaning. From there, take the regional bus 230 towards Garching-Forschungszentrum. Reserve 45-60 minutes for this trip.
- Special requirements:
If you have special dietary requirements or require additional assistance, please indicate this in the application form. Please also contact us if you require assistance with visa applications or have any other questions, even before submitting your application.
- Geo-INQUIRE and ChEESE-2P:
The SeisSol and ExaHyPE User Workshop and Training is supported by the projects Geo-INQUIRE and ChEESE-2P.
Inclusion criteria: We aim to make the workshop an inclusive event. Geo-INQUIRE and ChEESE-2P promote diversity and inclusion within the scope of the projects. Therefore, applications from female colleagues and from colleagues working in one of the widening countries, associated countries, or outermost regions of Horizon Europe will receive special attention during the evaluation process. Widening countries are Bulgaria, Croatia, Cyprus, Czechia, Estonia, Greece, Hungary, Latvia, Lithuania, Malta, Poland, Portugal, Romania, Slovakia, and Slovenia. Associated countries (allowed to coordinate widening projects) include Albania, Armenia, Bosnia and Herzegovina, the Faroe Islands, Georgia, Kosovo, Moldova, Montenegro, Morocco, North Macedonia, Serbia, Tunisia, Turkey, and Ukraine. The outermost regions include Réunion, Mayotte, the Canary Islands, the Azores, Madeira, Saint-Martin, Guadeloupe, Martinique, and Guyana.
Geo-INQUIRE is funded by the European Commission under project number 101058518 within the HORIZON-INFRA-2021-SERV-01 call. Terms and Conditions for participants in Geo-INQUIRE activities: https://www.geo-inquire.eu/about/terms-and-conditions
ChEESE-2P is funded by the European High Performance Computing Joint Undertaking (JU) and by national funding from Spain, Italy, Iceland, Germany, Norway, France, Finland and Croatia under grant agreement No 101093038.
The registration form link is below. Completion of the form does not mean automatic acceptance of the participant. Due to limited seating, a selection of participants may be necessary. Participants will be informed of their acceptance to the event via email in mid-March 2026.
