Corresponding Receive Routine of MPI_Bcast

Question

What would be the corresponding MPI receive routine of the broadcast routine, MPI_Bcast.

Namely, one processor broadcasts a message to a group, let\'s say all world,

Answer 1

MPI_Bcast is both the sender and the receiver call.

Consider the prototype for it.

int MPI_Bcast ( void *buffer, int count, MPI_Datatype datatype, int root, MPI_Comm comm )

All machines except for the machine with id = root are receivers. The machine that has the id = root is the sender.
