MPI_Bcast

MPI_Bcast. Bcast stands for broadcast, and is used to send data from one process to all other processes. The format for this function is: MPI_Bcast(&msg_address,#_elements,MPI_Type, ID, Communicator). MPI_Bcast (&k, 1, MPI_INT, 0, MPI_COMM_WORLD) Process 0 sends k to all other processes.
