The European HPC Joint Undertaking has announced two new supercomputer systems—DAEDALUS and Arrhenius—joining the global TOP500 rankings in the latest edition released June 23, 2026. This expansion reinforces Europe's portfolio of high-performance computing infrastructure across the continent.

JUPITER, an existing EuroHPC system, maintains a top-five position globally with exascale capabilities. The latest TOP500 and Green500 rankings now feature all operational EuroHPC supercomputers, underscoring the initiative's growing computational presence.

The addition of these systems reflects sustained European investment in HPC infrastructure, positioning the region competitively in the global compute hierarchy at a time when AI training and inference workloads are increasingly driving demand for large-scale processing power.
