Jupyter port forwarding from HPC node to a local machine [Oregon State University]

port-forwarding.txt

1. I set this on my local machine and flip
`alias port_map='f(){ ssh -N -L "$2":localhost:"$2" panditb@"$1".engr.oregonstate.edu;  unset -f f; }; f'`

2. Enter into flip3 (use same node to re-establish connection to HPC if lost, eg '3' here)
`ssh panditb@flip3.engr.oregonstate.edu`

3. Enter HPC and whatever node thereafter (For example if you connect to cn-gpu5, hostname will be gpu5). 
`ssh panditb@compute-{hostname}.hpc.engr.oregonstate.edu`

4. I start the jupyter on node
`jupyter lab --no-browser --port 8888`

5. I go back to flip and forward HPC node to itself
`port_map compute-{hostname} 8888`

6. I go back to local machine and forward flip node to itself
`port_map flip3 8888`

7. Now access `localhost:8888` for jupyter lab on your local machine. *Make sure to change your username above. Also use tmux go to back and forth easily*
