Detailed Documentation

Threadpool interoperability namespace.
Global Functions
dnnl::stream make_stream( const dnnl::engine& aengine, threadpool_iface* threadpool )
Constructs an execution stream for the specified engine and threadpool.
Parameters:
aengine
Engine to create the stream on.
threadpool
Pointer to an instance of a C++ class that implements dnnl::threapdool_iface interface.
Returns:
An execution stream.
See also:
threadpool_iface* get_threadpool(const dnnl::stream& astream)
Returns the pointer to a threadpool that is used by an execution stream.
Parameters:
astream
An execution stream.
Returns:
Output pointer to an instance of a C++ class that implements dnnl::threapdool_iface interface or NULL if the stream was created without threadpool.
