Summary

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.

For EuroHPC access, users will not be provided with a Fido account, so they should send the public SSH key to support@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.

After a successful login, some useful shell command and several text editors can be used.

For file management several moun tpoints are provided. For transferring files, please refer to section Transfer files.
