NVIDIA CUDA
===========

CUDA (Compute Unified Device Architecture) is a parallel computing platform and programming model created by NVIDIA.  It can be used to increase computing performance by leveraging the Graphics Processing Units (GPUs).

xCAT supports CUDA installation for both diskful and diskless nodes using the ``otherpkgs`` mechanism.  The following OS and architecture combinations are supported by NVIDIA's CUDA repository:

Within the NVIDIA CUDA Toolkit, installing the ``cuda`` package will install both the ``cuda-runtime`` and the ``cuda-toolkit``.  The ``cuda-toolkit`` is intended for developing CUDA programs and monitoring CUDA jobs.  If your particular installation requires only running GPU jobs, it's recommended to install only the ``cuda-runtime-<major>-<minor>`` package (e.g., ``cuda-runtime-13-2``).
