## 4.4.1. Example using MPI_BCAST

Up: Broadcast Next: Gather Previous: Broadcast

Example

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.
