Hi Dominik,
If your openmpi is properly compiled and your modules program works fine but
the openmpi test fails because of the switcher issue, then here is my simple
therapy.
1. First of all, check to see if openmpi was compile with the "tm" support
module load openmpi
ompi_info | grep tm # if you see any output about tm here, that is good
2. Chroot to image and then setup switcher manually.
chroot /var/lib/systemimager/images/oscarimage
cd /opt/env-switcher/share/env-switcher/mpi
ls # check to see what mpi switcher is configured.
# OSCAR is supposed to configure three mpi names (lam, mpich, and
openmpi) by default
# If there is anything missing, the corresponding test would fail.
cp /opt/openmpi-switcher-modulefile-1.2.4/share/openmpi/openmpi-1.2.4 . #
Assuming openmpi name is missing.
3. Once the image is updated, reimage your client nodes with the new image
4. Or not recommend but cpush the missing mpi names to the client nodes.
cd /opt/env-switcher/share/env-switcher/mpi
cpush openmpi-1.2.4
BTW, what kind of error did you get when you compiled modules-oscar? What did
you change on the modules-oscar.spec file?
