I don¹t immediately see anything in your configuration that would cause the
problem you describe. We haven¹t seen any problems running non-mpi apps as
I mentioned in another posting, we do it regularly, both threaded and
non-threaded. My best guess is that there is something preventing openmpi
from finding/running your remote executable.
As I mentioned in the other posting, I would suggest upgrading to the 1.2
release as it handles such problems better than 1.1.x. If you do and you
continue to see a problem, you could run with debug-daemons mca
odls_base_verbose 1 and send me the resulting output so we can figure out
what is going on.
