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.

MPI_Isend - Starts a standard-mode, nonblocking send.

BTW, are there any asynchronous collective operations?

Dear All:
How to do asychronous communication among nodes by openMPI or boot.MPI in cluster ?

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
