EUPEX leverages the best of the assets developed in previous H2020 projects to design, build and validate the first HPC platform integrating the full spectrum of European HPC technologies, from architecture, processors and interconnect to system software. This exascale platform, named the EUPEX Pilot, will be co-designed with European industrial, research organisations and universities.

The pilot system has been conceived as modular, thanks to the OpenSequana-compliant hardware platform and the matching HPC software ecosystem implementing the Modular Supercomputing Architecture. This enables EUPEX to integrate and efficiently manage a variety of hardware modules, including upcoming architectures, and to handle heterogeneous workflows.

The project aims to demonstrate the maturity and scalability of European hardware and software technologies, with a strong emphasis on preparing applications and users to operate efficiently on the upcoming exascale architecture. This effort goes well beyond hardware, with a particular focus on energy efficiency. Dedicated software tools will be developed and deployed to monitor energy consumption and to optimise codes so as to reduce the overall power usage of HPC clusters. A representative set of applications (spanning climate and weather forecasting, biology and health, remote sensing analysis, material science, astrophysics, engineering and seismology) will be optimised for the target architecture, benchmarked on the EUPEX Pilot, and analysed to provide recommendations for future European Exascale systems.
