===========================
GPU-enabled MPAS-Atmosphere
===========================

|

This documentation describes a special branch of the MPAS-Model code with modifications to enable the MPAS-Atmosphere model to run on heterogeneous compute nodes through the use of OpenACC directives.

|

.. note::
   The use of the GPU-enabled MPAS-Atmosphere code assumes a thorough understanding of the standard MPAS-Atmosphere model. If you are new to MPAS-Atmosphere, please begin with the `CPU-only, v7.0 release`_ of the model.

|

The remaining sections of this documentation provide details on how to obtain, compile, and run the code on supported platforms.


.. _`CPU-only, v7.0 release`: https://github.com/MPAS-Dev/MPAS-Model/releases/tag/v7.0
