MPI_Bcast - Broadcasts a message from the process with a
       specified rank (called a root) to all other processes of
       the group


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Bcast ( buffer, count, datatype, root, comm )
            void             *buffer;
            int               count;
            MPI_Datatype      datatype;
            int               root;
            MPI_Comm          comm;

       C++:

            #include <mpi.h>

            void Intracomm::Bcast(
            void*             buffer,
            int               count,
            const Datatype&   datatype,
            int               root) const

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            <type> BUFFER(*)
            INTEGER count, datatype, root, comm,
            ierror

            CALL MPI_BCAST(buffer, count, datatype, root,
            comm, ierror)


STANDARDS

       This release implements the MPI 1.2 standard, as
       documented by the MPI Forum in the spring 1997 release of
       MPI:  A Message Passing Interface Standard.


DESCRIPTION

       The MPI_Bcast routine broadcasts a message from the
       process with a specified rank (called a root) to all other
       processes of the group.  This routine accepts the
       following parameters:

       buffer         Specifies the starting address of the
                      buffer (choice)

                      buffer (integer)

       datatype       Specifies the data type of the buffer
                      (handle)

       root           Specifies the rank of the broadcast root
                      (integer)

       comm           Specifies the communicator (handle)

       ierror         Specifies the return code value for
                      successful completion, which is in
                      MPI_SUCCESS.  MPI_SUCCESS is defined in the
                      mpif.h file.
