NAME

       MPI_Comm_remote_size   -  Determines  the  size  of  the  remote  group
       associated 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++
       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.
