 +==== Run job using a GPU ====
 +Currently there is only one compute node with GPU capabilities. As of February 2026, compute06 has an NVIDIA Tesla v100 with 32GB of RAM. In order to use this you will need to add an extra "gres" line to your SLURM sbatch job specification.
 +
 +For example, ''beast-gpu.sbatch'':
 +
 +<code>#!/usr/bin/bash
 +#SBATCH -p batch
 +#SBATCH -w compute06
 +#SBATCH --gres=gpu:v100:1
 +#SBATCH -n 8
 +#SBATCH -J beast-GPU
 +
 +# load module(s)
 +module load beagle/3.1.2
 +module load beast/1.10.4
