MPI_Irecv and MPI_Recv are nonblocking and blocking functions for receiving messages regardless of mode.   

Besides receive and send functions MPI offers a number of more useful functions for communications. A number of them are being introduced here.

MPI_Buffer_attach used to offer buffer space for buffered mode. Nonblocking functions comprise request argument used subsequently to conclude whether requested operation has finished.

MPI_Wait and MPI_Test test or wait for completion of nonblocking communication. 

MPI_Probe and MPI_Iprobe search for incoming message without really receiving it. Information regarding message concluded by probing can be used to determine how to receive it.

MPI_Cancel withdraws outstanding message request useful for cleanup at end of a program or after major stage of computation.
