VScode workflow

Many users prefer to use VS Code. However, if you connect VS Code directly to the login node, your session may be terminated if your process consumes high CPU or memory. Always use a compute node for heavier workloads.

The following is the VScode workflow to remotely connect to a compute node from your laptop:

Open a terminal on your laptop (not VS Code), and run:

ssh user_id@XXXX-login.ornl.gov

Submit a job and launch an interactive session on a compute node:

srun -A XXXX -p XXXX -N 1 -n 1 -c 1 --mem=8G -t 1:00:00 --pty /bin/bash

Run the following command to find the compute node hostname:

hostname

Example output:

mod-condo-c74

Remember this hostname and add the following to your SSH config file on your local laptop: macOS/Linux: ~/.ssh/config Windows: C:\Users\YourName.ssh\config

Host cades-login
    HostName XXXX-login.ornl.gov
    User your_uid
Host cades-compute
    HostName mod-condo-XXX.ornl.gov
    User your_uid
    ProxyJump cades-login

Replace mod-condo-XXX with your actual compute node (e.g., mod-condo-c74).

Open VS Code on your laptop and connect to:

cades-compute
