Function Documentation

dnnl_binary_desc_init()

dnnl_status_t DNNL_API dnnl_binary_desc_init	(	dnnl_binary_desc_t *	binary_desc,
		dnnl_alg_kind_t	alg_kind,
		const dnnl_memory_desc_t *	src0_desc,
		const dnnl_memory_desc_t *	src1_desc,
		const dnnl_memory_desc_t *	dst_desc
	)

Initializes a descriptor for a binary primitive.

Note

Memory descriptor dst_desc is allowed to be initialized with dnnl_format_tag_any or with format_kind set to dnnl_format_kind_any.

Both memory descriptors must have the same number of dimensions. Element broadcasting is supported for memory descriptor src1_desc and are applied to @ src1_desc dimensions that have size equal to 1.

Inputs:

• src0 (dnnl_query_src_md, 0)
• src1 (dnnl_query_src_md, 1)

Outputs:

• dst (dnnl_query_dst_md, 0)

Parameters

binary_desc	Output descriptor for a binary primitive.
alg_kind	Algorithm kind. Valid values are dnnl_binary_add and dnnl_binary_mul.
src0_desc	Source 0 memory descriptor.
src1_desc	Source 1 memory descriptor.
dst_desc	Destination memory descriptor.

Returns

dnnl_success on success and a status describing the error otherwise.
