Virtual Studio Code

The currently only acceptable way to run vscode on the cluster is via the one of our web portals. By default, running VS Code with the normal "Remote-SSH" extension will run on a cluster login node, which puts undue stress on the login node.

RStudio Server

If you’re trying to run a Singularity image program like RStudio Server which requires creating an SSH tunnel, you cannot issue a Ctrl+C key combination from within the terminal window of VSCode. That’s (almost certainly) not going to work.

The Ctrl+C sends an interrupt back to your original ssh connection from your laptop to the JHPCE login node. Since you’re using vscode to make that connection, it’s not a “real” ssh session, so it won’t be able to interpret the Ctrl+C. We don’t believe there is a way around that… but if you find one please let us know.
