Upgrade NVIDIA Driver
Update NVIDIA Driver
=====================
If the user wants to update the newer NVIDIA driver on the system, need to :doc:`create New CUDA software reposity </advanced/gpu/nvidia/repo/index>` . Assume the newer driver is in the ``/install/cuda-7.5/ppc64le/nvidia_new`` for the following processes.
If the user wants to update the newer NVIDIA driver on the system, follow the :doc:`Create CUDA software repository </advanced/gpu/nvidia/repo/index>` document to create another repository for the new driver.
The following example assumes the new driver is in ``/install/cuda-7.5/ppc64le/nvidia_new``.

Diskless
--------
For update new NVIDIA driver on the diskless compute node, the easy and simple way is re-generate the osimage with New NIVIDIA driver reposity and re-provision the node with this osimage because node needs to be reboot in order for NIVIDIA driver to load. Please follow :doc:`this doc </advanced/gpu/nvidia/osimage/index>` to create osimage definitions and deploy CUDA nodes.
To update a new NVIDIA driver on diskless compute nodes, re-generate the osimage pointing to the new NVIDIA driver repository and reboot the node to load the diskless image.
Refer to :doc:`Create osimage definitions </advanced/gpu/nvidia/osimage/index>` for specific instructions.
