Note that the default wrapper above automatically loads the latest version of the JuliaHPC module and, correspondingly, the latest Julia version. If you want to use a specific version, you may point the Julia VS Code extension to version specific wrapper scripts that we provide in the root directory of the module (given by the environment variable $EBROOTJULIAHPC after you’ve loaded the module). Example: /opt/software/pc2/EB-SW/software/JuliaHPC/1.8.2-foss-2022a-CUDA-11.7.0/julia_vscode on Noctua 2.

VS Code on compute nodes

We recommend the following two-step process

• 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* HostName %h ProxyJump n2-jumphost User [USERNAME] IdentityFile [PATH TO PRIVATE KEY] IdentitiesOnly yes # Noctua 1 Host cn-* gpu-* HostName %h ProxyJump noctua-jumphost User [USERNAME] IdentityFile [PATH TO PRIVATE KEY] IdentitiesOnly yes

Manual approach (not recommended)
