                                       {
 
  // Create the stream object.
  m_stream = std::make_unique<const Details::Stream>();
 
  // Tell the user what happened.
  ATH_MSG_INFO("Initialized HIP stream on device: " << m_stream->name());
 
  // Return gracefully.
  return StatusCode::SUCCESS;
}

◆ stream()

hipStream_t AthHIP::SingleStreamSvc::stream ( const EventContext & ctx ) const

overridevirtual

Get the HIP stream to use.

Parameters

ctx	The event context for which the stream is requested

Returns: The HIP stream to use for the current event context
