First, open a terminal, login to the cluster and request an interactive session on one of the compute nodes.
- Remember the name of the compute node that was assigned to you, e.g. n2cn1234.
- Keep the terminal open until you’re done with your work.

Second, use VS Code’s remote extension to connect to the compute node via SSH.

For this to work, you need to be able to directly ssh n2cn1234 to the compute node. To avoid many entires in your ~/.ssh/config (one for each compute node) you can use the following entries for Noctua 1 and 2 based on wildcards (the jump hosts are defined here):

Code Block

# Noctua 2
Host n2cn* n2lcn* n2gpu* n2fpga* n2dgx* n2hcn*
    HostName %h
    ProxyJump n2-jumphostn2login2
    User [USERNAME]
    IdentityFile [PATH TO PRIVATE KEY]
    IdentitiesOnly yes
    
# Noctua 1
Host cn-* gpu-*
    HostName %h
    ProxyJump noctua-jumphostln2
    User [USERNAME]
