Mathematica 
------------

Overview
^^^^^^^^^

Mathematica is available on the HPC cluster via the `Environment Modules` system. The software is installed centrally in:

::

    /opt/mathematica

Loading the Module
^^^^^^^^^

Before using Mathematica, load the environment module:

::

    module load mathematica

You can verify it is working by checking the version:

::

    math -version

Using Mathematica with SLURM
^^^^^^^^^

You can use Mathematica either interactively or via batch jobs.

Interactive Job Example (srun)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To launch an interactive Mathematica session on a compute node:

::

    srun --pty --ntasks=1 --cpus-per-task=1 --mem=2G --time=00:30:00 bash
    module load mathematica
    math

This starts an interactive kernel on an allocated node.

Batch Job Example (sbatch)
~~~~~~~~~~~~~~~~~~~~~~~~~~

To run a Mathematica script (`script.m`) in batch mode:

.. code-block:: bash

    #!/bin/bash
    #SBATCH --job-name=math_batch
    #SBATCH --ntasks=1
    #SBATCH --cpus-per-task=1
    #SBATCH --mem=4G
    #SBATCH --time=01:00:00
    #SBATCH --output=math_output.log

    module load mathematica/14.2.1

    math -script script.m

Replace `script.m` with your actual Mathematica file.

Using WolframScript
^^^^^^^^^

WolframScript allows inline evaluation or execution of `.wls` scripts:

Run code directly:

::

    wolframscript -code 'FactorInteger[123456]'

Or execute a script:

::

    wolframscript -file myanalysis.wls

Submitting as a batch job:

.. code-block:: bash

    #!/bin/bash
    #SBATCH --job-name=wolframscript_job
    #SBATCH --ntasks=1
    #SBATCH --mem=2G
    #SBATCH --time=00:10:00

    module load mathematica

    wolframscript -file myanalysis.wls
