Gaining Access to SLING clusters

Access is enabled both through ARC middleware and directly via SLURM interface on command line. Generally accessible clusters that provide direct access are NSC, Maister and Trdina.

Obtaining user account for direct access via SLURM command line

For using SLURM, user has to access login node. Login node is a computer, directly connected to the cluster and configured so it can communicate with its controller. It has installed the necessary tools for working in command line.

  • Login node is part of the cluster, command line and SSH protocol are used for access.
  • For access to node via SSH, users need SLING SSO account (FreeIPA server https://fido.sling.si/).
  • Access is available to users in university, educational, research and industry-research institutions as well as Arnes users.
  • There are different types of access: national open access (enabling personal, project based and test access), workshops and, in some cases, access via institution or project.
  • Some login nodes only allow access with SSH key, taht you can upload via https://fido.sling.si
  • To access Maister cluster, IP address needs to be communicated to hpc.podpora@um.si

You can request user account at:

  • SLING support: support@sling.si
