The NAISS Large Spring 2026 round is open

Deadline for submission:  21 April 2026 at 15:00 CEST .

News

• NAISS has changed the structure of application rounds. NAISS no longer has separate compute, storage, and sensitive data rounds. It is now possible to apply for compute resources, storage resources and resources for sensitive data in the same proposal.
• To encourage our largest users to apply for EuroHPC resources, there are now upper limits on the capacity you can request in this Large round.
• The project publication lists for earlier NAISS projects should not be included as text in the uploaded Activity Report PDFs. Instead, you register publications resulting from the projects (and acknowledging the use of NAISS resources) via DOIs in SUPR. This will enable NAISS to better present the large scientific output resulting from the use of our resources. The publication list you include as part of the Large proposal itself is still uploaded as a PDF.
• Financial support is now entered in a table with a row for each grant or similar instead of being a free-text field.
• You now have to acknowledge that NAISS storage resources are to be used for active data only. You have to continuously remove non-active data during the allocation period. In your data management plan you have to declare how you will handle your data after the allocation has ended.
• We encourage users to apply for all their needs in a single proposal. NAISS recognises that there may be special cases which might require more than one proposal, for example if an applicant has a need to handle both sensitive and non-sensitive data, but access to the sensitive data should be restricted to a subset of co-investigators. A request for any such exception should be clearly motivated in the proposals.

Due to the changes described above, you might need to allocate a bit more time than usual this year to complete your proposal.

NAISS Large Spring 2026 round

The application round for NAISS compute resources, storage resources, and resources for sensitive data, larger than what is available in the Medium round.

Information and instructions are available at the NAISS user website: https://hpc.pages.naiss.se/user-documentation/support-docs/allocations/largespring2026

The call for resources in SUPR: https://supr.naiss.se/round/spring2026large

Allocation period

The allocation period for the NAISS Large call is 1 July 2026 through 30 June 2027.

Please note that the deadline for submissions to the call is:  21 April 2026 at 15:00 CEST . After that time, access to the online application system for these calls is closed.

The National Allocations Committee (NAC), with the help of external experts, will review the proposals submitted within the deadline. The proposals will undergo both scientific and technical evaluation. Decisions regarding the NAISS Large Spring 2026 round will be announced via email no later than late May.

How to apply

We encourage you to read the instructions, including what to do if you now have both a compute and a storage project, carefully before submitting your proposal. Instructions are available at the NAISS user website and in SUPR on the links above.

Please also note:

• NAISS explicitly request acknowledgement of NAISS in scientific publications that have utilized NAISS resources, services, or expertise.
  Papers, presentations, and other publications that feature work that relied on NAISS resources should include an acknowledgement.
  For more information, visit the NAISS website: https://www.naiss.se/policies/acknowledge.
• If you have previously been granted NAISS resources, you have to upload activity reports for those projects to be eligible for new allocations.
• While in the SUPR portal, please review your personal information to ensure that you have filled out all mandatory fields.
