.SH DESCRIPTION
|
|
.ft R
|
|
MPI_Open_port establishes a network address, encoded in the \fIport_name\fP string, at which the server will be able to accept connections from clients. \fIport_name\fP is supplied by the system.
|
|
.sp
|
|
MPI copies a system-supplied port name into \fIport_name\fP. \fIport_name\fP 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.
|
|
|
|
.SH SUPPORTED INFO KEYS
|
|
None.
|
|
|
|
.SH 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.
|
|
.sp
|
|
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.
