Slovenian National Supercomputing Network

National calls for open 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, adopted by the SLING Council. 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:

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 an access proposal for any of the envisaged types of access.

Development Access (DA)

Development access is mainly aimed at the development of software and algorithms.

Permanent Calls
