NAISS Large Storage Spring 2024 call

The following NAISS resources are available in the NAISS Large Storage Spring 2024 call (period 1 July 2024 – 30 June 2025):

  • Centre Storage – fast storage for data actively used on Tetralith
  • Crex 1 – fast storage for data actively used on Rackham and Snowy
  • Klemming – fast storage for data actively used on Dardel
  • Mimer – fast storage for data actively used on Alvis
  • dCache – geographically distributed storage

Who is eligible to apply?

This round is for researchers with an established track record of using HPC efficiently for their research projects and with resource requirements that exceed the limits of what can be applied for in the Medium round. Large proposals may request allocations on several resources.

The Principal Investigator (PI) is responsible for the proposal and usage of any granted resources. You cannot be a PI for Medium Compute and Large Compute resources simultaneously. If you are already the PI for a Medium resource it will be terminated if you are granted a Large allocation.

The applicant must be at least an assistant professor at an eligible Swedish institution. NAISS is financed by Swedish tax payers with the objective to strengthen science and research in Sweden. To apply for these resources, the PI must therefore hold an appointment of at least 60 percent at a Swedish university or research institution recognised by the Swedish Research Council.

The research supported by these resources must be predominantly carried out in Sweden. This aspect is taken into account during the evaluation and, in the case of strong competition, can be used to prioritise applications. Additionally, the applicant must have experience from using HPC resources at least at the Medium level, or a corresponding level abroad.

How to register a proposal

It is important that your proposal includes the intended usage and characteristics of the storage resources and application programmes that you would like to run.

The proposal is registered via the Swedish User and Project Repository (SUPR) website at

The deadline to submit a proposal for the Large Storage Spring 2024 call is 12 April 15:00 CEST.

If you have previously been granted NAISS resources, you have to upload activity reports for those projects to be eligible for new allocations.

PI information

Please review your personal information in SUPR and make sure that it is updated.

Project information

When registering a proposal in SUPR you must always provide the following basic information:

  • Project title
  • Affiliation – name of university/institute or similar
  • Abstract – a project abstract in English
  • Classification – according to VR classification codes

For Large Storage projects you also have to upload three separate PDF files with the following:

  1. The CV of the PI. Maximum 2 pages.
  2. A publication list of the PI.
  3. A project description. Maximum 5 pages. Please note that this is a summary of what should be included. You will find detailed instructions in SUPR when you are registering your proposal.
    • Overview (½ page)
      An abstract of the proposed research, data origin and planned analysis.
    • Data management plan (1½ page)
      Explain how your application makes efficient use of the requested resources and how data will be managed on the system. Motivate and provide explicit numbers related to size, generation rate, number of files etc.
    • Scientific challenges (2 pages)
      Explain how the proposed project is representing state-of-the-art research in your scientific area and the potential of expanding knowledge within it, and how you are planning to use adequate computational methods to address scientific questions.
      NOTE: If this proposal is linked to a NAISS Large Compute proposal applied for at the same time, just put “See Compute proposal”.
    • Research group and management (½ page)
      Describe the full research group that will be involved in the proposed project: names of members, HPC experience, positions, and roles.
    • References (½ page)
      A list of references that are relevant for the proposal, such as previous works, papers, and methods.

Review and notification of results

The review process commences after the allocations round has closed. Proposals are subject to scientific and technical review. Scientific review is performed by NAC and external evaluators, while technical review is performed by NAC-WG (the NAC Working Group).

Decisions about the Large Spring 2024 rounds will be announced by email in late May.
