Function Documentation

dnnl_reorder_primitive_desc_create()

dnnl_status_t DNNL_API dnnl_reorder_primitive_desc_create	(	dnnl_primitive_desc_t *	reorder_primitive_desc,
		const dnnl_memory_desc_t *	src_desc,
		dnnl_engine_t	src_engine,
		const dnnl_memory_desc_t *	dst_desc,
		dnnl_engine_t	dst_engine,
		const_dnnl_primitive_attr_t	attr
	)

Creates a primitive descriptor for a reorder primitive.

Inputs:

• src (dnnl_query_src_md, 0)

Outputs:

• dst (dnnl_query_dst_md, 0)

Parameters

reorder_primitive_desc	Output primitive descriptor.
src_desc	Source memory descriptor.
src_engine	Engine on which the source memory object will be located.
dst_desc	Destination memory descriptor.
dst_engine	Engine on which the destination memory object will be located.
attr	Primitive attributes to use (can be NULL).

Returns

dnnl_success on success and a status describing the error otherwise.

Examples:

cnn_inference_f32.c, cpu_cnn_training_f32.c, and cross_engine_reorder.c.
