When a user is eligible to use HPC Vega they can get "cluster access" via Slurm or Nordugrid ARC. Vega only allows login with an SSH key, so your user's public SSH key must be generated on Linux/Mac or on Windows. Users should then upload the public key to the account on fido.sling.si.
If you are a Vega user with a SLING approved allocation, please upload the public part of your new SSH-key pair onto your account on the SLING Identity Managment server.
When accessing HPC Vega, several SSH Clients can be used for logging in to login nodes. For example, Linux/Mac users can connect from Linux/Mac terminal, Windows users can connect using Putty. Please refer to Troubleshooting tips if you have any issues when connecting to HPC Vega.
We also enable users to access the cluster through a web interface on the portal Open Ondemand. This makes it possible to access files on the cluster, upload them, submit and monitor jobs, and check their status in the queue.
NorduGrid-ARC job submission and management is explained in a separate section.
