Example using MPI_BCAST

 
  
 

Broadcast 100 ints from process  0 to every 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.
