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(const stream& astream, const std::unordered_map<int, memory>& args)
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.
