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_Comm_connect  - Establishes communication with a server.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Comm_connect(char *port_name, MPI_Info info, int root,
	    MPI_Comm comm, MPI_Comm *newcomm)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_COMM_CONNECT(PORT_NAME, INFO, ROOT, COMM, NEWCOMM, IERROR)
	    CHARACTER*(*)  PORT_NAME
	    INTEGER	   INFO, ROOT, COMM, NEWCOMM, IERROR

C++ Syntax
       #include <mpi.h>
       MPI::Intercomm MPI::Intracomm::Connect(const char* port_name,
	    const MPI::Info& info, int root) const

INPUT PARAMETERS

       port_name Port name (string, used only on root).

       info	 Options given by root for the connect (handle, used only on root). No options currently supported.

       root	 Rank in comm of root node (integer).

       comm	 Intracommunicator over which call is collective (handle).

OUTPUT PARAMETERS

       newcomm	 Intercommunicator with client as remote group (handle)

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_Comm_connect establishes communication with a server specified by port_name. It is collective over the calling communicator and returns
       an intercommunicator in which the remote group participated in an MPI_Comm_accept. The MPI_Comm_connect call must only be called after  the
       MPI_Comm_accept call has been made by the MPI job acting as the server.

       If the named port does not exist (or has been closed), MPI_Comm_connect raises an error of class MPI_ERR_PORT.

       MPI  provides  no guarantee of fairness in servicing connection attempts. That is, connection attempts are not necessarily satisfied in the
       order in which they were initiated, and competition from other connection attempts may prevent a particular connection attempt  from  being
       satisfied.

       The port_name parameter is the address of the server. It must be the same as the name returned by MPI_Open_port on the server.

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.
