# Jupyter Notebook on Remote Computer

- Try this new server from uc davis first: https://video.ucdavis.edu/media/t/1_5h2fi1wh

The below uses the mambaforge installation of conda.

First, create a mamba environment containing jupyter notebook:

mamba create -y -n jup notebook nb_conda_kernels

Activate it:

mamba activate jup

Set a password:

jupyter notebook password

Create a script ```run-jupyter-on-node.sh``` containing:

#! /bin/bash -eu

# initialize conda
conda_base=$(conda info --base)
. ${conda_base}/etc/profile.d/conda.sh

# activate relevant environment - CUSTOMIZE ME
conda activate jup

### pick a port
read LOWERPORT UPPERPORT < /proc/sys/net/ipv4/ip_local_port_range

port="$(shuf -i $LOWERPORT-$UPPERPORT -n 1)"
while :; do
  netstat -taln | egrep ":$port.*LISTEN" || break
  port="$(shuf -i $LOWERPORT-$UPPERPORT -n 1)"
done

### print out stuff
cat <<EOF

You need to use SSH tunneling to port forward from your desktop to Jupyter Lab.

Run the following command in a new terminal on your machine:

ssh -L${port}:${HOSTNAME}:${port} $[e-mail] -N

Then point your browser to http://localhost:${port}

EOF

### run me!
jupyter notebook --no-browser --ip=${HOSTNAME} --port=${port}

and then run with srun:

srun -p high2 --time=5:00:00 --nodes=1 \
            --cpus-per-task 4 --mem 64GB \
            --pty bash ./run-jupyter-on-node.sh
