MPI_Comm_create - Creates a new communicator


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Comm_create ( comm, group, comm_out )
            MPI_Comm  comm;
            MPI_Group group;
            MPI_Comm *comm_out;

       C++:

            #include <mpi.h>

            Intracomm Intracomm::Create(
            const Group&      group) const

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER comm, group, newcomm, ierror,

            CALL MPI_COMM_CREATE(comm, group, newcomm,
            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_Comm_create routine creates a new communicator.
       This routine accepts the following parameters:

       comm      Specifies a communicator (handle)

       group     Specifies the group, which is a subset of the
                 group of comm (handle)

       comm_out  Returns a new 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.
