MPI_Comm_remote_size(3OpenMPI)                                                MPI_Comm_remote_size(3OpenMPI)



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.
