MPI_Open_port(3OpenMPI) 												   MPI_Open_port(3OpenMPI)

NAME

       MPI_Open_port - Establishes a network address for a server to accept connections from clients.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Open_port(MPI_Info info, char *port_name)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_OPEN_PORT(INFO, PORT_NAME, IERROR)
	    CHARACTER*(*)  PORT_NAME
	    INTEGER	   INFO, IERROR

C++ Syntax
       #include <mpi.h>
       void MPI::Open_port(const MPI::Info& info, char* port_name)

INPUT PARAMETER

       info	 Options on how to establish an address (handle). No options currently supported.

OUTPUT PARAMETERS

       port_name Newly established port (string).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Open_port  establishes  a network address, encoded in the port_name string, at which the server will be able to accept connections from
       clients. port_name is supplied by the system.

       MPI copies a system-supplied port name into port_name. port_name identifies the newly opened port and can be used by a  client  to  contact
       the server. The maximum size string that may be supplied by the system is MPI_MAX_PORT_NAME.

SUPPORTED INFO KEYS

       None.

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.

NAME

       MPI_Open_port -	Establish a server port for client MPI connections

SYNOPSIS

       #include <mpi.h>
       int
       MPI_Open_port(MPI_Info info, char* port_name)

INPUT PARAMETERS

       info   - extra information handle
       port_name
	      - newly established port

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.

USAGE WITH IMPI EXTENSIONS

       The IMPI standard only supports MPI-1 functions.  Hence, this function is currently not designed to operate within an IMPI job.

ERRORS

       If an error occurs in an MPI function, the current MPI error handler is called to handle it.  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  (in  C and Fortran; this error handler is less useful in with the C++ MPI bindings.  The predefined error handler
       MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the error value needs to be recovered).  Note that MPI does not guarantee that an MPI
       program can continue past an error.

       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.  The C++ bindings for MPI do not return error values; instead, error values are communicated by throwing  exceptions	of
       type MPI::Exception (but not by default).  Exceptions are only thrown if the error value is not MPI::SUCCESS
	.

       Note  that  if the MPI::ERRORS_RETURN handler is set in C++, while MPI functions will return upon an error, there will be no way to recover
       what the actual error value was.
       MPI_ERR_OTHER
	      - Other error; use MPI_Error_string to get more information about this error code.
       MPI_ERR_INTERN
	      - An internal error has been detected.  This is fatal.  Please send a bug report	to  the  LAM  mailing  list  (see  http://www.lam-
	      mpi.org/contact.php ).
