Global Functions
dnnl_status_t DNNL_API dnnl_stream_create( dnnl_stream_t* stream, dnnl_engine_t engine, unsigned flags )
Creates an execution stream.
Parameters:
stream |
Output execution stream. |
engine |
Engine to create the execution stream on. |
flags |
Stream behavior flags ( |
Returns:
dnnl_success on success and a status describing the error otherwise.
See also:
dnnl_status_t DNNL_API dnnl_stream_get_engine( const_dnnl_stream_t stream, dnnl_engine_t* engine )
Returns the engine of a stream object.
Parameters:
stream |
Stream object. |
engine |
Output engine on which the stream is created. |
Returns:
dnnl_success on success and a status describing the error otherwise.
dnnl_status_t DNNL_API dnnl_stream_wait(dnnl_stream_t stream)
Waits for all primitives in the execution stream to finish computations.
Parameters:
stream |
Execution stream. |
Returns:
dnnl_success on success and a status describing the error otherwise.
dnnl_status_t DNNL_API dnnl_stream_destroy(dnnl_stream_t stream)
Destroys an execution stream.
Parameters:
stream |
Execution stream to destroy. |
Returns:
dnnl_success on success and a status describing the error otherwise.
