for years, were probably tremendously confused by this typo -- trying to code their applications by catching MPI:Exception instances, but failing to compile them. "Why, cruel world, why?!" Now we have fixed the error; all is right with the world again. This commit was SVN r23469.

.SH DESCRIPTION
|
|
.ft R
|
|
This routine removes the pair (\fIservice_name, port_name\fP) so that
|
|
applications may no longer retrieve \fIport_name\fP by calling
|
|
MPI_Lookup_name. It is an error to unpublish a \fIservice_name\fP
|
|
that was not published via MPI_Publish_name. Both the \fIservice_name\fP
|
|
and \fIport_name\fP arguments to MPI_Unpublish_name must be identical
|
|
to the arguments to the previous call to MPI_Publish_name.
|
|
|
|
.SH INFO ARGUMENTS
|
|
The following keys for \fIinfo\fP are recognized:

Key Type Description
|
|
--- ---- -----------
|
|
|
|
ompi_global_scope bool If set to true, unpublish the name from
|
|
the global scope. Unpublish from the local
|
|
scope otherwise. See the NAME SCOPE
|
|
section for more details.

|
|
\fIbool\fP info keys are actually strings but are evaluated as
|
|
follows: if the string value is a number, it is converted to an
|
|
integer and cast to a boolean (meaning that zero integers are false
|
|
and non-zero values are true). If the string value is
|
|
(case-insensitive) "yes" or "true", the boolean is true. If the
|
|
string value is (case-insensitive) "no" or "false", the boolean is
|
|
false. All other string values are unrecognized, and therefore false.
|
|
.PP
|
|
If no info key is provided, the function will first check to see if a
|
|
global server has been specified and is available. If so, then the
|
|
unpublish function will default to global scope first, followed by local. Otherwise,
|
|
the data will default to unpublish with local scope.
|
|
|
|
.SH NAME SCOPE
|
|
Open MPI supports two name scopes: \fIglobal\fP and \fIlocal\fP. Local scope
|
|
values are placed in a data store located on the mpirun of the calling
|
|
process' job, while global scope values reside on a central server. Calls
|
|
to MPI_Unpublish_name must correctly specify the scope to be used in
|
|
finding the value to be removed. The function will return an error if
|
|
the specified service name is not found on the indicated location.
|
|
.sp
|
|
For a more detailed description of scoping rules, please see the MPI_Publish_name
|
|
man page.
|
|
|
|
.SH ERRORS
|
|
.ft R
|
|
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.
|
|
