This repository contains materials for the Julia/JuMP tutorial, held at the Los Alamos National Laboratory Grid Science Winter School, January 7-11, 2019.

This README will walk you through how to install Julia and IJulia.

To get started, you first need to install Julia.

• Download and install Julia v1.0.2 from https://julialang.org/downloads/.

Windows 7 Users: as instructed on the downloads page, you will need to install at least version 3.0 of the Windows Management Framework.

Next, you need to download a copy of these materials.

• If you have git installed, (after cd'ing to an appropriate directory) run

git clone https://github.com/lanl-ansi/tutorial-grid-science-2019

• If you don't have git installed (i.e., the above command fails), download this zip file. Once downloaded, unzip it to an appropriate location.

Now open Julia, either by typing julia at a terminal, or from where ever you installed it. Once open, you should be faced with the Julia REPL that looks like this:

Now we need to install Jupyter. In the Julia REPL, run the following commands (this may take a little bit of time):

import Pkg
Pkg.add("IJulia")

Okay, last step, let's launch a Jupyter notebook! Open a Julia REPL and then run:

using IJulia
IJulia.notebook(dir="/path/to/tutorial-grid-science-2019")

Note: we've had some reports that dir="~" fails on some NIX machines. Use an absolute path instead.

If all goes well, a browser window will open that looks like this:
