Detailed Documentation

Reorder primitive.

Construction

reorder()

Default constructor. Produces an empty object.

reorder(const primitive_desc& pd)

Constructs a reorder primitive.

Parameters:

pd	Primitive descriptor for reorder primitive.

reorder(const primitive_desc& pd, const std::vector<uint8_t>& cache_blob)

Constructs a reorder primitive from a cache blob.

Parameters:

pd	Primitive descriptor for reorder primitive.
cache_blob	Cache blob.

reorder(
    const memory& src,
    const memory& dst,
    const primitive_attr& attr = primitive_attr()
    )

Constructs a reorder primitive that would reorder data between memory objects having the same memory descriptors as memory objects src and dst.

Parameters:

src	Source memory object.
dst	Destination memory object.
attr	Primitive attributes to use (optional).

Methods

void execute(const stream& astream, memory& src, memory& dst) const

Executes the reorder primitive.

Parameters:

astream	Stream object. The stream must belong to the same engine as the primitive.
src	Source memory object.
dst	Destination memory object.

void execute()

Executes computations specified by the primitive in a specified stream.

Arguments are passed via an arguments map containing <index, memory object> pairs. The index must be one of the DNNL_ARG_* values such as DNNL_ARG_SRC, and the memory must have a memory descriptor matching the one returned by primitive_desc::query_md (query::exec_arg_md, index) unless using dynamic shapes (see DNNL_RUNTIME_DIM_VAL).

Parameters:

astream	Stream object. The stream must belong to the same engine as the primitive.
args	Arguments map.
