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 a project proposal for any of the envisaged types of projects.
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.
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.
