thanks I know this. but, what if sender can send a lot of messages to receivers faster than what receiver can receive ? it means that sender works faster than receiver. Any help is appreciated. jack

I need to set up a kind of asychronous communication protocol such that message senders and receivers can communicate asychronously without losing anymessages between them. I do not want to use blocking MPI routines because the processors can do otheroperations when they wait for new messages coming. I donot find this kind of MPI routines that support this asychronous communication. Any help is appreciated. thanks Jack June 27 2010 The New Busy think 9 to 5 is a cute idea.
