Notes: • A maximum of COUNT items of type DTYPE are accepted; if the message contains more, it is an error. • The sending and receiving processes must agree on the datatype; if they disagree, results are undefined (MPI does not check). • When this routine returns, the received message data have been copied into the buffer; and the tag, source, and actual count of data received are available via the status argument. Example: MPI_Recv(c,10,MPI_INT,1,10,MPI_COMM_WORLD,&stat); MPI_Recv(&d,1,MPI_DOUBLE,0,19,Comm1,&stat);
