The examples in this section use intra-communicators.
Example
Broadcast 100 ints from MPI process 0 to every MPI process in the group.
MPI_Comm comm; int array[100]; int root=0; ... MPI_Bcast(array, 100, MPI_INT, root, comm);As in many of our example code fragments, we assume that some of the variables (such as comm in the above) have been assigned appropriate values.
