Slovenian National Supercomputing Network

Calls for access and use of resources

SLING National Open Access

Access and use of supercomputer capacities in open access are governed by the Rules for access and use of supercomputer capacities in open access, which were adopted by the SLING Council at its regular meeting on February 1, 2023. They refer to clusters of those organizations or system administrators included in the SLING consortium who want to offer part of their capacities for general, open use in a uniform and organized manner to all eligible users in Slovenia.

Within the framework of SLING, on the basis of these rules, it is possible to obtain part of the supercomputing capacities of the following clusters:

  • Vega – Institute of Information Sciences, IZUM Maribor
  • Arnes – Arnes, Ljubljana

Beneficiaries

Beneficiaries for capacity allocation can be individual applicants or groups. When the capacity is assigned to a group, the applicant must specify in the application the person who conducts the research and is responsible for the list of participants in the research who use the allocated capacities. The type and size of the allocated capacity depends on the role and importance of the project, so that all users or groups who are entitled to apply can submit a project proposal for any of the envisaged types of projects.

Details of eligible users and groups can be found here.

Types of projects and calls

When registering a project, the applicant must choose one of the planned types of projects listed below that best suits the purpose of the application. Projects differ in purpose, amount of allocated resources, and time limit for resource allocation.

  1. Large research project (LRP)

    They are large projects intended for production use, as well as for the development of software systems and algorithms, adaptation of existing software, or methodology testing of specific scientific prototypes, when large amounts of computing resources or data stores must be used for the process or due to the amount of data.

  2. Regural research projects (RRPs)

    Regular research projects are projects intended for production use of supercomputing capacities or data storage allocations when the requirements are not very large.

  3. Development projects (DP)

    Development projects are mainly aimed at the development of software and algorithms. A development project can also be a research project with limited resource needs, a test or development project, or a project with specific goals, for example for data post-processing and visualization.

  4. Test projects (TP)

    Test projects are intended for new users of the SLING infrastructure to learn how to use the available systems and to test the software and algorithms before preparing a larger project proposal. It is also suitable for existing users who need an allocation to test new software or applications and want to prepare appropriate benchmarking, performance and scalability analyses.
