Thank you. Theme. Light Dark High contrast Previous The send buffer specified by the MPI_SEND operation consists of count successive entries of the type indicated by datatype, starting with the entry at address buf. Note that we specify the message length in terms of number of elements, not number of bytes. The former is machine independent and closer to the application level. 2013-02-13 · MPI_Send: send data to another process MPI_Send(buf, count, data_type, dest, tag, comm) 15 Arguments Meanings buf starting address of send buffer count # of elements data_type data type of each send buffer element dest processor ID (rank) destination tag message tag comm communicator C/C++:MPI_Send(&x,1,MPI_INT,5,0,MPI_COMM_WORLD); 2008-12-01 · I am using IT++ for some of my code and I tried to parallelize it.

At first, it might seem that MPI_Bcast is just a simple wrapper around MPI_Send and MPI_Recv. In fact, we can make this wrapper function right now. Our function, called my_bcast is located in bcast.c.
