MPI_Comm_remote_group(3)           Open MPI           MPI_Comm_remote_group(3)



NAME
       MPI_Comm_remote_group  - Accesses the remote group associated with an
       intercommunicator.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Comm_remote_group(MPI_Comm comm, MPI_Group *group)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_COMM_REMOTE_GROUP(COMM, GROUP, IERROR)
            INTEGER   COMM, GROUP, IERROR


C++ Syntax
       #include <mpi.h>
       Group Intercomm::Get_remote_group() const


INPUT PARAMETER
       comm      Communicator.


OUTPUT PARAMETERS
       group     Remote group of communicator.

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_Comm_remote_group accesses the remote group associated with an
       intercommunicator.

       The intercommunicator accessors (MPI_Comm_test_inter,
       MPI_Comm_remote_size, MPI_Comm_remote_group) are all local operations.


ERRORS
       Almost all MPI routines return an error value; C routines as the value
       of the function and Fortran routines in the last argument. C++
       functions do not return errors. If the default error handler is set to
       MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI error handler is
       called. By default, this error handler aborts the MPI job, except for
       I/O function errors. The error handler may be changed with
       MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN
       may be used to cause error values to be returned. Note that MPI does
       not guarantee that an MPI program can continue past an error.
