Non-Blocking Communication
[Point-to-Point Communication]
|
Detailed Description
Internals about non-blocking communication.The SPUs are very limited in usage, e.g. only one thread per SPU is supported, and so it is hard to make communication non-blocking. In fact only synchronous send and receive provide possibilities for non-blocking communication. Because we think that the advantages of a non-blocking receive aren't worth the effort, only non-blocking send is implemented at the moment. The picture below illustrates a non-blocking synchronous communication call.
