thanks
I know that. 
MPI_irecv() ;
do other works;
MPI_wait();
But, my message receiver is much slower than sender. 
when the receiver is doing its local  works, the sender has sent out their messages. but at this time, the receiver is very busy doing its local work and cannot post MPI_irecv to get the messages from senders. 
Any help is appreciated.
