Starting 1 January 2023, the National Academic Infrastructure for Supercomputing in Sweden (NAISS) is the new organization for high-performance computing, storage, and data services for academic users in Sweden. Linköping university is the host organization for NAISS, but NAISS acts independently with a national perspective and responsibility.


NAISS takes over the role previously held by SNIC. The Swedish Research Council (VR) decided in 2021 to discontinue the financing of the consortia-organized SNIC and instead announce a call for a new, more unified organization, with one host university. Linköping University submitted the application for NAISS during spring 2022 with supporting letters from the Rectors of nine other Swedish universities. VR decided to grant the application in June 2022 and in December 2022 the final agreements regarding the grant conditions where signed by VR and LiU.

From the users perspective, there will initially only be minimal differences between the SNIC and NAISS regimes. The allocation process for resources will continue in the same way as previously, se below for more information on NAISS Rounds of applications. Some other frequently asked question (FAQ) about the transition is outlined below.

NAISS will take over the financing of the current SNIC-systems Dardel, Tetralith, Alvis, Bianca and Rackham, as well as storage systems and cloud services located at different sites across Sweden. Over time, NAISS will consolidate new hardware resources to a single national site. Staff and support functions will continue to be distributed across Sweden as NAISS will establish local branches in collaboration with universities.


  • What types of resources will NAISS provide to support Swedish research?

    NAISS will provide HPC, storage, and data resources, including systems suitable for machine-learning and AI tasks. The starting point is that NAISS takes over the responsibility for all the previous SNIC systems that has been planned to run beyond 2022. Notably Dardel, Tetralith, Alvis, Bianca and Rackham. From the users perspective, 2023 will be extremely similar to 2022. Then, NAISS will set up new resources, replacing the old and covering the growing needs among Swedish academic users of HPC resources.

  • Our project was awarded a SNIC allocation that runs into 2023 - will anything about that change?

    All projects that were awarded SNIC allocations (of computation time and/or storage and/or application expert assistance) in 2023 will be continued under NAISS – so the allocations effectively stay the same. Log in, software, hardware, the SUPR-portal, etc stay the same. Smaller changes, e.g. in acknowledgement texts in publications, updates in user agreements etc will be communicated to the users in early 2023.

  • Our project has been awarded a new SNIC allocation that will start in 2023 - how will we log in and use the systems/storage?

    In exactly the same way as previously under SNIC during 2022. The systems and storage stay the same. The user and project portal SUPR stays the same.

  • How, when and where can our project apply for a NAISS allocation?

    From 2 January 2023 in the SUPR portal, just as under SNIC during 2022. Applications sent in to SNIC very late 2022 will be handed over to NAISS.

  • Where/how can our project get help to prepare an application for a NAISS allocation?

    All applications for NAISS allocations will be done through the same SUPR system as previously under SNIC. All documentation needed is present at the existing web resources that will be kept on-line during a transition time until the web resources have been fully updated. If additional help is needed, contact

  • From 2023 onwards, who should we contact if our project has problems using NAISS resources?

    Support for problems using NAISS resources should be sought for in the very same ways as under SNIC, for example using the support form in SUPR. NAISS, including local NAISS branches, will continue to run existing systems and provide support for them in terms of system support and first and mid-level users support. Advanced user support, mainly funded by universities as in-kind contributions to SNIC, will be continually funded by the universities and coordinated by NAISS.

  • How will support services work under NAISS?

    To a large degree, support functions and support channels for users of NAISS resources during 2023 will be the same as for SNIC users during 2022. Use the support form in SUPR. The web and its support content will be kept online until the web is complete.

  • Will NAISS be running training events to help researchers to improve their high-performance computing skills and/or to use NAISS systems?

    Yes. NAISS will run NAISS-training events for this purpose building on the positive experience from the SNIC-training. Information about these activities will be provided at the website and through e-mail to users of NAISS-resources.

Application rounds for compute and storage resources

The NAISS application rounds and the handling of proposals to those are very similar to the SNIC rounds 2022.

The NAISS Large spring 2023 rounds are now open for proposals with submission deadline 12 April 2023 at 3 PM CEST:

Other NAISS rounds that are open for proposals:

In the fall of 2023, NAISS will issue calls for:

  • NAISS Large Compute Fall 2023
  • NAISS Large Storage Fall 2023
  • LUMI Sweden Fall 2023
