.. _cusolverMpHandle_t-label:

--------------------------
:code:`cusolverMpHandle_t`
--------------------------

   | The `cusolverMpHandle_t` structure holds the cusolverMp library context (device properties, system information, etc.).
   | The handle must be initialized and destroyed using :ref:`cusolverMpCreate() <cusolverMpCreate-label>` and :ref:`cusolverMpDestroy() <cusolverMpDestroy-label>` functions respectively.


.. _cudaLibMpGrid_t-label:

-----------------------
:code:`cudaLibMpGrid_t`
-----------------------

   | The `cudaLibMpGrid_t` structure holds information about the grid dimensions and stores the communicator associated to the grid of processes.
   | It must be initialized and destroyed using :ref:`cusolverMpCreateDeviceGrid() <cusolverMpCreateDeviceGrid-label>` and :ref:`cusolverMpDestroyGrid() <cusolverMpDestroyGrid-label>` functions respectively.

.. _cudaLibMpMatrixDesc_t-label:

-----------------------------
:code:`cudaLibMpMatrixDesc_t`
-----------------------------

   | The `cudaLibMpMatrixDesc` structure captures the shape and characteristics of a distributed matrix.
   | It must be initialized and destroyed using :ref:`cusolverMpCreateMatrixDesc() <cusolverMpCreateMatrixDesc-label>` and :ref:`cusolverMpDestroyMatrixDesc() <cusolverMpDestroyMatrixDesc-label>` functions respectively.
