Off the Wire Press Releases Sept. 8, 2026 — Today, the EuroHPC Joint Undertaking (EuroHPC JU), together with the National Academic Infrastructure for Supercomputing in Sweden (NAISS), inaugurated Arrhenius, a new EuroHPC supercomputer located in Sweden. This world-class supercomputer was unveiled in Linköping University during a ribbon-cutting ceremony. The event was attended by Anders Dam Jensen, EuroHPC JU Executive Director, and Lotta Edholm, Minister for Upper Secondary School, Higher Education and Research. Anders Jensen, EuroHPC JU Executive Director stated: “With the inauguration of Arrhenius, I am delighted to welcome a new mid-range supercomputer to our EuroHPC portfolio of HPC systems, marking another step towards enhanced European technological sovereignty. Arrhenius’ ability to carry out highly demanding computational tasks will allow our users to push boundaries in scientific and technological simulations, helping to drive breakthroughs in areas like drug discovery and climate change mitigation.” The Arrhenius Supercomputer Arrhenius is a mid-range supercomputer capable of executing more than 60 petaflops, the equivalent of over 60 million billion operations per second. It ranked 42nd in the latest TOP500 list of the world’s most powerful supercomputers, published in June 2026. Designed to handle complex simulations and compute-intensive AI applications, it will enable simulations in areas such as climate modelling, materials science, life sciences, and engineering. The machine will benefit a wide spectrum of users across Europe, including researchers, industries, and the public sector. Arrhenius’s strong security and data integrity criteria make it perfect for private companies’ proprietary product development and sensitive research involving personal data. Arrhenius also combines high performance with energy efficiency. As part of the EuroHPC JU’s ongoing efforts to procure more energy-efficient supercomputers, the system delivers more than 61 billion operations per watt, placing it 24th in the latest Green500 list and highlighting its strong energy efficiency. Through the EuroHPC AI for science access call, European users have already begun using Arrhenius ahead of its official inauguration, giving researchers early access to the new supercomputer. Arrhenius is now available to a wider range of users through the EuroHPC regular access call, as well as through the benchmark and development modes. More Details The supercomputer was named after Carl Axel Arrhenius, a Swedish geologist and chemist who, in 1787, discovered the mineral gadolinite, which was later found to contain several unknown elements called rare earth elements. The system was procured under a EuroHPC JU contract signed with HPE in July 2025. The estimated total value for Arrhenius is EUR 68.5 million. It is co-funded up to 35% by the EuroHPC JU, with funding provided through the Digital Europe Programme (DEP) and contributions from the Swedish Research Council to NAISS. The EuroHPC JU and NAISS, hosted by Linköping University, jointly manage access to compute resources on the new machine in proportion to their respective investments. To ensure an appropriate uptake by industry and public sector users, organisations like RISE, Research Institutes of Sweden, and ENCCS, the EuroCC National Competence Center Sweden, are also involved in the process.
