IA migration §5: new Julia page (P2.11) (via create-page on MediaWiki MCP Server)

New page

[https://julialang.org/ Julia] is a high-level, high-performance language for technical computing. This page covers using Julia on Anunna.

== Loading Julia ==

Julia is provided through the module system. Load a [[Environment Modules|bucket]] first, then Julia:

<syntaxhighlight lang="bash">
module load 2024
module load Julia
</syntaxhighlight>

To see which versions are available, use <code>module spider Julia</code> (see [[Environment Modules]]).



== Packages ==

Julia manages its own packages with the built-in package manager (<code>Pkg</code>). By default packages install into your home directory under <code>~/.julia</code>. Because [[Home Directory|home]] is small and not meant for heavy I/O, point Julia's depot at a larger [[Compute Storage|Lustre]] location by setting <code>JULIA_DEPOT_PATH</code> before starting Julia:

<syntaxhighlight lang="bash">
export JULIA_DEPOT_PATH=/lustre/nobackup/<group>/<user>/julia_depot
</syntaxhighlight>

Then add packages from the Julia REPL:

<syntaxhighlight lang="julia">
import Pkg
Pkg.add("DataFrames")
</syntaxhighlight>

== Running Julia in a job ==

Run Julia scripts as batch jobs through the scheduler — see [[Batch Jobs]]. For interactive work, start an [[Interactive Jobs|interactive job]] first.

To use multiple cores, start Julia with the <code>-t</code> (threads) option, or use Julia's distributed/parallel facilities — see [[Performance Optimization/Multiple CPUs]]:

<syntaxhighlight lang="bash">
julia -t $SLURM_CPUS_PER_TASK myscript.jl
</syntaxhighlight>
