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.

The Arrhenius supercomputer, inaugurated in September 2026.

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 have just installed a new mid-range supercomputer, Arrhenius, in Linköping. 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

Panel discussion on AI and sustainability.

Researchers call for greater responsibility and sustainability in AI development

AI development must be matched by responsibility, improved governance, and sustainability. That is the message from scientists at Linköping University, who met across disciplines to discuss values, security, environmental impacts and AI politics.

How AI changes human decision-making

AI can find patterns that people miss, but it does not automatically lead to better decisions. New research from Linköping University shows how the roles of humans and AI change depending on the situation and the decision being made.

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.
