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++ 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.
