Re: [ptp-dev] Orte jobs do not stop

[wspear <wspear@xxxxxxxxxxxxxx>]

I've got a little more information on this issue now.  It occurs when
OpenMPI has been configured with:

--enable-mpi-threads
--with-devel-headers
--enable-orterun-prefix-by-default
 --with-tm=/opt/torque

Apparently for any version of OpenMPI (tested with 1.2.3 and 1.2.6).
It does not occur when --enable-mpi-threads and
--enable-orterun-prefix-by-default are omitted.

I guess the focus now is on getting the new launch manager together,
but if any of this suggests a work-around for the current release,
please let me know.
