Research Computing

Julia is free and open-source software distributed under the MIT licence. No UCL licence or activation key is required.

• Official Julia installation instructions
• Julia downloads
• Julia licence

Windows

The Julia project recommends Juliaup, which installs Julia, manages versions, and configures the command line.

1. Open Microsoft Store and install Julia, or open a terminal and run:

winget install --name Julia --id 9NJNWW8PVKMN -e -s msstore

1. Open a new terminal and start Julia:

julia

1. Check the version inside Julia:

versioninfo()

macOS

Install Juliaup from Terminal:

curl -fsSL https://install.julialang.org | sh

Open a new Terminal window and start Julia:

julia

The official macOS disk image is an alternative if Juliaup is unsuitable.

Myriad

Do not install a separate system copy of Julia. Check whether an appropriate module is already available:

module avail julia

Load one of the versions shown, replacing the example module name with an available version:

module load julia
julia --version

Use the login node only to inspect modules, prepare files, and submit jobs. Run substantial Julia calculations on compute nodes through Sun Grid Engine. A minimal job script is:

#!/bin/bash -l
#$ -l h_rt=0:10:0
#$ -l mem=2G
#$ -l tmpfs=10G
#$ -pe smp 1
#$ -N julia_example
#$ -cwd

module load julia
julia analysis.jl

Submit it from a directory in Scratch with qsub julia-job.sh. Confirm the current module name on Myriad before using this example.

Condenser

First ask the VM administrator whether Julia is already installed. For a personal user-space installation on a suitable VM, Juliaup is the recommended upstream method and does not require a UCL licence. For a shared installation, the VM administrator should choose and maintain the version.

Licence

Julia's MIT licence permits academic and commercial use. Individual Julia packages have their own licences, so check package terms when redistribution or commercial use matters.
