The Group

We are a research group at the Institute for High-Performance Computing in Stuttgart, University of Stuttgart, Germany. Our research at the IHR and the High-Performance Computing Center Stuttgart (HLRS) started in May 2025 and is growing continuously. We started as a group founded by Johannes Gebert that, at first, relied heavily on student research assistants. As the group grows, the students and the full-time colleagues become increasingly professional, with research and publications that speak for themselves.
