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 an address that can be used to establish  connections between groups of MPI processes

SYNOPSIS

       int MPI_Open_port(MPI_Info info, char *port_name)

INPUT PARAMETER

       info   - implementation-specific information on how to establish a port for MPI_Comm_accept (handle)

OUTPUT PARAMETER

       port_name
	      - newly established port (string)

NOTES

       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 .

RESERVED INFO KEY VALUES

       ip_port
	      - Value contains IP port number at which to establish a port.
       ip_address
	      - Value contains IP address at which to establish a port.  If the address is not a valid	IP  address  of  the  host  on	which  the
	      MPI_OPEN_PORT call is made, the results are undefined.

THREAD AND INTERRUPT SAFETY

       This  routine  is  thread-safe.	This means that this routine may be safely used by multiple threads without the need for any user-provided
       thread locks.  However, the routine is not interrupt safe.  Typically, this is due to the use of memory allocation routines such as  malloc
       or other non-MPICH runtime routines that are themselves not interrupt-safe.

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_Comm_set_errhandler  (for  communicators), MPI_File_set_errhandler (for files), and
       MPI_Win_set_errhandler (for RMA windows).  The MPI-1 routine MPI_Errhandler_set may be used but its  use  is  deprecated.   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; however, MPI implementations will attempt to continue whenever possible.

       MPI_SUCCESS
	      - No error; MPI routine completed successfully.
