NAME

       MPI_Comm_remote_size  - Determines the size of the remote group associ-
       ated with an intercommunicator.

SYNTAX


C Syntax

       #include <mpi.h>
       int MPI_Comm_remote_size(MPI_Comm comm, int size)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_COMM_REMOTE_SIZE(COMM, SIZE, IERROR)
            INTEGER   COMM, SIZE, IERROR

C++ Syntax

       #include <mpi.h>
       int Intercomm::Get_remote_size() const

INPUT PARAMETER

       comm      Communicator (handle).

OUTPUT PARAMETERS

       size      Number of processes in the remote group of comm (integer).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_Comm_remote_size determines the size of 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++  func-
       tions  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.
