main(int argc, char **argv) 
   { 
     int me, count; 
     void *data; 
     ... 

MPI_Init(&argc, &argv); MPI_Comm_rank(MPI_COMM_WORLD, &me);

if(me == 0) { /* get input, create buffer ``data'' */ ... }

MPI_Bcast(data, count, MPI_BYTE, 0, MPI_COMM_WORLD);

...

MPI_Finalize(); }

This example illustrates the use of a collective communication.
