CUDA
----
If the version of CUDA available from your distro is not adequate, manually install CUDA.

.. Tip:: The version of CUDA you use will determine compatibility with various GPU generations.
   See `CUDA compatibility <https://docs.nvidia.com/deploy/cuda-compatibility/index.html>`_ for more info.

   Select the appropriate run file based on your desired CUDA version and architecture according to
   `CUDA Toolkit Archive <https://developer.nvidia.com/cuda-toolkit-archive>`_.

.. code-block:: bash

   wget https://developer.download.nvidia.com/compute/cuda/11.4.2/local_installers/cuda_11.4.2_470.57.02_linux.run \
     --progress=bar:force:noscroll -q --show-progress -O ./cuda.run
   chmod a+x ./cuda.run
   ./cuda.run --silent --toolkit --toolkitpath=/usr --no-opengl-libs --no-man-page --no-drm
   rm ./cuda.run

npm dependencies
----------------
Install npm dependencies.
   .. code-block:: bash

      npm install

Build
-----
.. Attention:: Ensure you are in the build directory created during the clone step earlier before continuing.

.. code-block:: bash

   cmake ..
   make -j ${nproc}

   cpack -G DEB  # optionally, create a deb package
   cpack -G RPM  # optionally, create a rpm package
