Gihan Chanaka Jayatilaka : Blog : How to use VScode debugger on SLURM nodes?

1. SSH to your SLURM submission node (which has a public IP submissionnode.umd.edu) using a terminal application and request a compute node (using srun).
2. Run the command hostname to see the internal IP of the compute node. This will be computenode.umd.edu
3. Add the following onto your local computer's SSH config. This file is usually stored on ~/.ssh/config
   
   Host submissionnode
    Hostname submissionnode.umd.edu
    User gihan
   Host computenode
    Hostname computenode.umd.edu
    User gihan
    ProxyCommand ssh -W %h:%p submissionnode
   
   
   
4. Now you can connect to the compute node directly using remote explorer in VScode and use the debugger as usual.
