EUPEX – The European Pilot for Exascale

The EUPEX consortium aims to design, build, and validate the first EU platform for HPC, with European assets covering the spectrum of required technologies end to end: from architecture, processor, system software, and development tools to applications. The EUPEX prototype will be designed to be open, scalable, and flexible, and will include a modular OpenSequana-compliant platform and a corresponding HPC software ecosystem for its modular supercomputing architecture. Scientifically, EUPEX is a vehicle to prepare HPC, AI, and Big Data processing communities for upcoming European exascale systems and technologies. A strong emphasis is put on the system software stack and the applications. Being the first of its kind, EUPEX has set itself the ambitious challenge of gathering, distilling, and integrating European technologies that its scientific and industrial partners will use to build a production-grade prototype.

EUPEX is coordinated by ATOS. Besides JSC, 16 other academic and industry partners from all over Europe are participating in the project. The project is co-funded by EuroHPC JU and the national bodies of the partners involved, including the German Federal Ministry of Education and Research (BMBF). EUPEX was launched on 1 January 2022 and will run for four years with a total budget of € 40 million. Further information on the project will soon be available at

JSC will bring its many years of experience in the design, installation, and operation of large HPC systems into the project. Furthermore, FZJ will contribute its well-known open-source software in the form of tools for performance measurement and analysis (Scalasca, Score-P, CUBE) and for system monitoring (LLview). Finally, JSC will port and adapt artificial intelligence (AI) applications that cover machine and deep learning. The software developed by JSC within this project will be made openly available to help support the platform within the HPC community and beyond in the long term.
