Internal Deep Diamond API mostly relevant to programmers who write tools, extensions
and additional backend engines.

When implementing your own backend, in addition to the light documentation provided in this
namespace, please refer to the DNNL implementation and its tests. It is currently the most
complete one. Next, see the cuDNN GPU backend to see how it solves differences in general
approach to computation. There are countless small and not so small gotchas with these
complex technologies, so expect lots of debugging.
