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.
None.
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.
