Memory

There are two levels of abstraction for memory in oneDNN.

1. *Memory descriptor* -- engine-agnostic logical description of data (number
   of dimensions, dimension sizes, :ref:`data type <data_types-label>`, and
   :ref:`format <memory_formats-label>`.

2. *Memory object* -- an engine-specific object combines memory descriptor
   with storage.

oneDNN defines the following convenience aliases to denote tensor dimensions

.. doxygentypedef:: dnnl::memory::dim
   :project: oneDNN

.. doxygentypedef:: dnnl::memory::dims
   :project: oneDNN

.. toctree::
   :maxdepth: 2
