Swedish Supercomputing

Infrastructure for Swedish academic research

Since the start of 2023, NAISS , which is funded by the Swedish Research Council (VR), has had overall responsibility for the physical infrastructure providing supercomputer and data storage resources for academic research in Sweden. NAISS partners with Swedish universities to make these resources, as well as high-performance computing (HPC) training and user support, available to researchers. In addition, Sweden owns a share of the LUMI  petascale system, which is hosted in Finland.

Sweden is currently in a transition period as, prior to 2023, an earlier organisation known as the Swedish National Infrastructure for Supercomputing ( SNIC ) was responsible for physical HPC resources, as well as training and support, which were all provided through supercomputer centres hosted at six of the Swedish universities. Nowadays NAISS has agreements with various Swedish universities (which are referred to as NAISS branches in this context) to provide user support for academic researchers using the systems. The supercomputer, cloud and storage systems that were established under SNIC are continuing and being funded by NAISS till the ends of their life cycles, and meanwhile NAISS is working on establishing a single site in Sweden where future new NAISS supercomputer resources will be housed.

The six main academic supercomputer centres in Sweden are:

• the Chalmers Centre for Computational Science and Engineering  (C3SE) at Chalmers University of Technology in Gothenburg, which hosts the Alvis accelerator-based NAISS system dedicated for research using artifical intelligence techniques,

• the High Performance Computing Center North  (HPC2N) at Umeå University,

• Lunarc  at Lund University,

• the National Supercomputer Centre  at Linköping University, which hosts the NAISS general purpose computational resource Tetralith,

• the PDC Center for High Performance Computing at the KTH Royal Institute of Technology (KTH) in Stockholm, which hosts the NAISS Dardel system, and

• the Uppsala Multidisciplinary Centre for Advanced Computational Science  (UPPMAX) at Uppsala University, which hosts the NAISS systems Bianca (for analysing sensitive data) and Rackham (for life sciences research).

In addition, NAISS provides the Swedish Science Cloud and the Swestore data storage infrastructure, both of which are hosted by several of the centres.

Swedish academic researchers can apply to use the NAISS systems and data storage resources hosted at these Swedish centres through NAISS - for details, see the NAISS allocations page . Information about applying for an allocation on the Swedish share of the LUMI system is available on the NAISS page for the LUMI resource .

Using resources at PDC for business/industry research

Part of the Dardel system at PDC is funded separately by KTH and may be used by businesses for research purposes. Companies can make arrangements directly with PDC to use Dardel. Further information is available here  about using PDC’s services for business research, and information about the prices for using HPC resources hosted at PDC for business/industry research can be found here .
