Add instructions on setting up GPU nodes on AWS

 This will start a VM inside your cloud account, build the image and then shut down the VM.
 From that point on, any newly-started nodes will use the new image.

+We need to adapt the default packer image as out of the box it does not
+contain any of the nvidia software necessary to interact with the GPU.
+
+The first step is to change the ``compute_image_extra.sh`` script to
+install the nvidia driver and CUDA toolchain:
+
+.. code-block:: shell-session
+
+   [citc@mgmt ~]$ cat >> compute_image_extra.sh <<EOF
+   sudo dnf config-manager --add-repo https://developer.download.nvidia.com/compute/cuda/repos/rhel8/x86_64/cuda-rhel8.repo
+   sudo dnf clean all
+   sudo dnf -y install kernel-devel
+   sudo dnf -y module install nvidia-driver:latest-dkms
+   sudo dkms autoinstall
+   EOF
+
+We can now re-build the image used to provision compute nodes:
+
+.. code-block:: shell-session
+
+   [citc@mgmt ~]$ sudo /usr/local/bin/run-packer
+
+Once this has succesfully completed you will be able to launch jobs on compute
+nodes with nvidia GPUs.
