MPI_Bcast(3)

NAME
     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)

     count          Specifies the number of entries in the 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.
