There was a bug in early Torque 2.1.x versions (I'm afraid I don't
remember which one) that -- I think -- had something to do with a faulty
poll() implementation. Whatever the problem was, it caused all TM
launchers to fail on OSX.
 
Can you see if the Torque-included tool pbsdsh works properly? It uses
the same API that Open MPI does (the "tm" api).
 
If pbsdsh fails, I suspect you're looking at a Torque bug. I know that
Garrick S. has since fixed the problem in the Torque code base; I don't
know if they've had a release since then that included the fix.
 
If pbsdsh works, let us know and we'll track this down further.

        Subject: [OMPI users] OpenMpi 1.1 and Torque 2.1.1
        
        
        I'm having trouble getting OpenMPI to execute jobs when
submitting through Torque.
        Everything works fine if I am to use the included mpirun
scripts, but this is obviously
        not a good solution for the general users on the cluster.
        
        I'm running under OS X 10.4, Darwin 8.6.0. I configured OpenMpi
with:
        export CC=/opt/ibmcmp/vac/6.0/bin/xlc
        export CXX=/opt/ibmcmp/vacpp/6.0/bin/xlc++
        export FC=/opt/ibmcmp/xlf/8.1/bin/xlf90_r
        export F77=/opt/ibmcmp/xlf/8.1/bin/xlf_r
        export LDFLAGS=-lSystemStubs
        export LIBTOOL=glibtool
        
        PREFIX=/usr/local/ompi-xl
        
        ./configure \
            --prefix=$PREFIX \
            --with-tm=/usr/local/pbs/ \
            --with-gm=/opt/gm \
            --enable-static \
            --disable-cxx
        
        I also had to employ the fix listed in:
        http://www.open-mpi.org/community/lists/users/2006/04/1007.php
        
        
        I've attached the output of ompi_info while in an interactive
job. Looking through the list,
        I can at least save a bit of trouble by listing what does work.
Anything outside of Torque
        seems fine. From within an interactive job, pbsdsh works fine,
hence the earlier problems
        with poll are fixed.
        
        Here is the error that is reported when I attemt to run hostname
on one processor:
