cuda setup scripts

==================
|
||||
|
||||
This section documented NVIDIA CUDA Toolkit v11 installation on the power9 rhels8.1 system.
|
||||
This sample documents installation of the NVIDIA CUDA Toolkit v11 on IBM POWER9 servers as part of xCAT diskful provisioning of Red Hat Enterprise Linux 8.1.
|
||||
For ``CUDA11``, there is a known issue that prevents successful installion of the nvidia-drivers module as part of the operating system kickstart install process used by diskful provisioning.
|
||||
Diskless provisioning can still be performed using the traditional osimage method; these instructions apply to diskful provisioning only.

Postscripts
|
||||
^^^^^^^^^^^
|
||||
|
||||
xCAT provides ``cuda_power9_setup`` postscripts to setup additional configuration to install NVIDIA POWER9 CUDA driver. For ``CUDA11``, it has issue to installing nvidia-drivers modules with kickstart. To workaround this problem, xCAT provides another postscripts ``cuda11_power9_setup``, the CUDA packages will be installed from this postscripts instead from package list and this is only apply to the diskfull installation.
|
||||
For ``CUDA11``, there is a known issue that prevents successful installion of the nvidia-drivers module as part of the Red Hat kickstart install process used by diskful provisioning. As an example method to work around this problem, refer to the postscript named ``cuda11_power9_setup``. This postscript will install the NVIDIA CUDA packages directly instead of relying on the osimage package list mechanism. ``cuda11_power9_setup`` is only needed for diskful provisioning.
