Enum Values
-----------

.. index:: pair: enumvalue; dnnl_accumulation_mode_strict
.. _doxid-group__dnnl__api__accumulation__mode_1ggaaafa6b3dae454d4bacc298046a748f7fafb83d4725f8c96479cd558a23cd60b6d:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dnnl_accumulation_mode_strict

Default behavior, f32/f64 for floating point computation, s32 for integer.

.. index:: pair: enumvalue; dnnl_accumulation_mode_relaxed
.. _doxid-group__dnnl__api__accumulation__mode_1ggaaafa6b3dae454d4bacc298046a748f7fa9d1932f25fb8115758987627620d0c7d:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dnnl_accumulation_mode_relaxed

Same as strict but allows some partial accumulators to be rounded to src/dst datatype in memory.

.. index:: pair: enumvalue; dnnl_accumulation_mode_any
.. _doxid-group__dnnl__api__accumulation__mode_1ggaaafa6b3dae454d4bacc298046a748f7fab49ca983cbe38a75a1ff0948c55f74bb:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dnnl_accumulation_mode_any

uses fastest implementation, could use src/dst datatype or wider datatype for accumulators
