NAME

       MPI_Comm_remote_size -  Determines the size of the remote group  associated with an inter-
       communictor

SYNOPSIS

       #include "mpi.h"
       int MPI_Comm_remote_size ( MPI_Comm comm, int *size )

INPUT PARAMETER

       comm   - communicator (handle)

OUTPUT PARAMETER

       size   - number of processes in the group of comm (integer)

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME  and  MPI_WTICK  )  have  an  additional
       argument  ierr  at  the  end  of  the  argument list.  ierr is an integer and has the same
       meaning as the  return  value  of  the  routine  in  C.   In  Fortran,  MPI  routines  are
       subroutines, and are invoked with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All  MPI  routines  (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as
       the value of the function and Fortran routines in the last argument.  Before the value  is
       returned,  the current MPI error handler is called.  By default, this error handler aborts
       the MPI job.  The error handler may be changed with MPI_Errhandler_set  ;  the  predefined
       error  handler  MPI_ERRORS_RETURN  may be used to cause error values to be returned.  Note
       that MPI does not guarentee that an MPI program can continue past an error.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_COMM
              - Invalid communicator.  A common error is to use a null  communicator  in  a  call
              (not even allowed in MPI_Comm_rank ).
       MPI_ERR_ARG
              -  Invalid  argument.  Some argument is invalid and is not identified by a specific
              error class (e.g., MPI_ERR_RANK ).
