National Academic Infrastructure for Supercomputing in Sweden (NAISS)

NAISS is the national academic infrastructure for supercomputing in Sweden. We provide researchers with high-performance computing (HPC) resources, storage capacity, and data services – free of charge.

NAISS is by far the largest and most widely used research infrastructure in Sweden, serving more than 8,600 users at some 30 universities and research institutes (2025). We offer a qualified and decentralised support through our branches across Sweden, to help users get maximum output from our resources.

We just installed a new mid-range supercomputer, Arrhenius, in Linköping. It is estimated to come into production in June 2026. Arrhenius is co-funded by the Swedish Research Council and EuroHPC JU (Joint Undertaking), an initiative between European countries and private partners that aims to put Europe at the forefront of supercomputing.

Together with our partner RISE (Research Institutes of Sweden) we are also operating Sweden AI Factory (formerly Mimer AI Factory). The Factory provides free access to powerful GPUs and a team of AI experts to help companies, researchers, and government agencies accelerate their AI projects, through learning and expert guidance to access to AI-optimised supercomputing resources. Later in 2026, a dedicated AI-optimised supercomputer will be installed in Linköping.

NAISS is hosted by Linköping University. We are funded by the Swedish Research Council and by our 13 partners:

  • Chalmers University of Technology
  • Karolinska Institutet
  • Linköping University
  • Linnaeus University
  • Luleå University of Technology
  • Lund University
  • Royal Institute of Technology / KTH
  • Stockholm University
  • SMHI (The Swedish Meteorological and Hydrological Institute)
  • Swedish University of Agricultural Sciences
  • Umeå University
  • University of Gothenburg
  • Uppsala University

Sweden’s fastest supercomputer strengthens European research

The Arrhenius Supercomputer at Linköping University is now inaugurated. Arrhenius strengthens LiU’s role in Swedish and European research infrastructure and is a resource for researchers in academia, industry and the public sector throughout Europe.

The supercomputer – a pillar of research

Sometimes there is a before and an after. Such as the mobile phone that changed our lives. Or supercomputers that help scientists in their everyday lives. Calculations that were impossible before are now being done around the clock.

National research infrastructure secures continued funding

The Swedish Research Infrastructure for Advanced Electron Microscopy, ARTEMI, has secured funding from the Swedish Research Council for another two years. It is crucial for advanced research in materials science, inorganic chemistry and physics.
