Creates a primitive descriptor for a reduction primitive.
Destination memory descriptor is allowed to be initialized with dnnl_format_tag_any or with format_kind set to dnnl_format_kind_any.
Parameters:
primitive_desc
Output primitive descriptor.
engine
Engine to use.
alg_kind
p
Algorithm specific parameter.
eps
Algorithm specific parameter.
src_desc
Source memory descriptor.
dst_desc
Destination memory descriptor.
attr
Primitive attributes (can be NULL).
Returns:
dnnl_success on success and a status describing the error otherwise.
