Documentation for using Julia with CURC OpenOnDemand

[ecooper-cu]

I recently got started with using Julia through CURC OpenOnDemand's VS Code-Server, and there are a couple of tips that I picked up along the way (thanks to the CURC staff) that might be useful to other users. I've detailed my workflow for getting started with Julia below:

1. Install the Julia extension for VS Code, and set the executable path to CURC's Julia installation.
   Notes: The extension ID is: julialang.language-julia. To set the path, go to the installed extension and select "Extension settings". Under the Remote [ondemand.rc.colorado.edu] user profile, edit the entry for "Julia: Executable Path". Several versions of Julia are stored in /curc/sw/julia, and you can set the executable path as /curc/sw/julia/<version>/bin/julia.

2. Activate the Julia REPL in the bash terminal using the same executable path (/curc/sw/julia/<version>/bin/julia)

3. Store Julia environments (or Projects) in the /projects/<user>/software/julia directory
   Notes: Julia installations can take up a lot of space, and exceed the limits in your /home/<user> directory. To create a new Julia environment or activate an existing one, activate the Julia REPL, enter package manager mode using the ] symbol, and type activate /projects/<user>/software/julia/<project name>.

4. Relocate .julia directory to /projects directory and update depot path with

mv ~/.julia /projects/<user>/.julia
echo 'export JULIA_DEPOT_PATH=/projects/<user>/.julia' >> ~/.bashrc
source ~/.bashrc

This prevents your Julia cache from filling up your home directory

@ecooper-cu thank you so much for submitting this issue! We will address this when time allows.

Note for our internal team: We had another user interested in a documentation section for Julia. Specifically on creating environments. We may want to consider this when time allows.
