In AscendCL Stream(AscendStream) is a task queue. Stream is used to manage the parallelism of tasks. The tasks inside a Stream are executed sequentially, that is, the Stream executes sequentially according to the sent tasks; the tasks in different Streams are executed in parallel.
All Non-blocking functions should pass parameter stream, These function returns immediately after the task is submitted. Caller should wait stream until completion.
Blocking functions implicityly use the default stream, and synchronize stream before function return.
