Pluto.ji interactive sessions

Warning

If you are using a windows computer, this method has currently been tested in VSCode, WSL powershell, and WSL Ubuntu. We have not tested it yet in Putty or Mobaxterm

To run Julia+Pluto.ji in interactive mode, first we need to load your interactive session:

srun --account nesi12345 --job-name "InteractiveJob" --cpus-per-task 2 --mem 8G --time 24:00:00 --pty bash

Then, we need to start up Julia and obtain the hostname and the port:

# Load Julia
module load Julia 

# Select a random port
PORT=$(shuf -i8000-9999 -n1)

# Check the hostname and port - we will need this later, you can also 
# see it at the start of your prompt
hostname | cut -d'.' -f1 # <-- This is the hostname
echo $PORT               # <-- This is the port

# Export port to a variable name
export pluto_port=${PORT}

Make a note of the hostname and the port, given by the hostname | cut -d'.' -f1 and echo $PORT commands. Then, we need to start up Julia, install and run Pluto.ji:

#Start Julia
julia

# Install Pluto.ji. This might take a minute
import Pkg; Pkg.add("Pluto")

# Start Pluto. This might take a minute
using Pluto
Pluto.run(host="0.0.0.0",port=parse(Int, ENV["pluto_port"]),launch_browser=false)

Take a note of the information given for the URL

└ 

Here, we will be using http://0.0.0.0:9627/?secret=mXmq6659 to access Pluto.

Next, open up a second terminal on your local machine (or a second screen in tmux or screen), and type the following:

ssh -L PORT:HOSTNAME:PORT mahuika

#For example:
#ssh -L 9627:mc081:9627 mahuika

Then, in your browser, type in the URL from before

http://0.0.0.0:PORT/?secret=SECRET

# For example:
# http://0.0.0.0:9627/?secret=mXmq6659

You will now be able to see and work wih Julia+Pluto in your web browser.
