MPI_Comm_remote_group(3OpenMPI)                                              MPI_Comm_remote_group(3OpenMPI)



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.
