This primitive is typically used to change the way the data is laid out in memory.

Global Functions

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.

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.
