Julia

The Julia programming language is a flexible dynamic language, appropriate for scientific and numerical computing, with performance comparable to traditional statically-typed languages. For more information visit: https://docs.julialang.org/en/v1/

Interactive Usage

After connecting to Stanage (see Establishing a SSH connection), start an interactive session with the following command:

srun --pty bash -i

Load a particular version of Julia with:

module load Julia/1.9.0-linux-x86_64

module load Julia/1.9.0-linux-x86_64

You can then start Julia with julia.

Batch Usage

Here, we assume that you wish to run the program example.jl on the system:

result = 0

# Prompt to enter
println("Enter 5 numbers line by line")

# Taking Input from user
for number in 1:5

num = readline()
num = parse(Int64, num)
global result+= num

end

println("The sum is :", result)

First, you need to write a batch submission file. We assume you’ll call this my_job.slurm:

#!/bin/bash
#SBATCH --ntasks=1
#SBATCH --time=10:00
#SBATCH --mem=100

#load the julia module
module load Julia/1.9.0-linux-x86_64

julia example.jl

Ensure that example.jl and my_job.slurm are both in your current working directory, then submit your job to the SLURM scheduler:

sbatch my_job.slurm

Installation notes

Julia version 1.9.0 was installed using Easybuild 4.8.1, build details can be found in $EBROOTJULIA/easybuild with the module loaded.

Testing

Testing has been conducted by running an interactive session and also submitting the above slurm job.
