Octave

GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable.

If you need to install a package that require Linux packages, you can send a message to the Service Desk and we will install them to the container.

Example batch jobs

Example about a serial batch script job on Puhti

#!/bin/bash
#SBATCH --account=<project>
#SBATCH --partition=small
#SBATCH --time=00:15:00
#SBATCH --nodes=1
#SBATCH --ntasks-per-node=1
#SBATCH --cpus-per-task=1
#SBATCH --mem-per-cpu=1000

module load octave
srun octave script.m

Submit the script with sbatch <script_name.sh>
