dnnl_sum_primitive_desc_create()

dnnl_status_t DNNL_API dnnl_sum_primitive_desc_create	(	dnnl_primitive_desc_t *	sum_primitive_desc,
		const dnnl_memory_desc_t *	dst_mds,
		int	n,
		const float *	scales,
		const dnnl_memory_desc_t *	src_mds,
		const_dnnl_primitive_attr_t	attr,
		dnnl_engine_t	engine
	)

Creates out-of-place sum_primitive_desc for sum of n inputs multiplied by scale with resulting output_desc memory descriptor.

output_desc can be NULL or specified with the dnnl_format_kind_any format kind – in this case, the appropriate memory format would be chosen automatically.

Inputs:

• src 0 (dnnl_query_src_md, 0)
• src 1 (dnnl_query_src_md, 1)
• ...
• src n - 1 (dnnl_query_src_md, n - 1)

Outputs:

• output (dnnl_query_dst_md, 0)
