RHEL 7.2 LE
===========
xCAT provides a sample package list files for CUDA. You can find them:
* Diskful: ``/opt/xcat/share/xcat/instal/rh/cuda*``
* Diskless: ``/opt/xcat/share/xcat/instal/rh/cuda*``
Diskful images
---------------
The following examples will create diskful images for ``cudafull`` and ``cudaruntime``. The osimage definitions will be created from the base ``rhels7.2-ppc64le-install-compute`` osimage.

* ``/opt/xcat/share/xcat/instal/rh/cudaruntime.rhels7.ppc64le.pkglist``
**[diskful note]**: There is a requirement to reboot the machine after the CUDA drivers are installed. To satisfy this requirement, the CUDA software is installed in the ``pkglist`` attribute of the osimage definition where the reboot happens after the Operating System is installed.

The following examples will create diskless images for ``cudafull`` and ``cudaruntime``. The osimage definitions will be created from the base ``rhels7.2-ppc64le-netboot-compute`` osimage.
**[diskless note]**: For diskless images, the requirement for rebooting the machine is not applicable because the images is loaded on each reboot. The install of the CUDA packages is required to be done in the ``otherpkglist`` **NOT** the ``pkglist``.
**[Note]**: For diskless, the install of the CUDA packages MUST be done in the ``otherpkglist`` and **NOT** the ``pkglist`` as with diskful. The requirement for rebooting the machine is not applicable in diskless nodes because the image is loaded on each reboot.
