I set up ompi before I configured Torque. Do I need to recompile
ompi
with appropriate torque configure options to get better integration?
If libtorque wasn't present on the machine at configure then yes, you
need to run:
./configure --with-tm=<path>
You don't *have* to do this, of course. If you've got it working
with ssh, that's fine. But the integration with torque can be better:
- you can disable ssh for non-root accounts (assuming no other
services need rsh/ssh)
- users don't have to setup ssh keys to run MPI jobs (a small thing,
but sometimes nice when the users aren't computer scientists)
- torque knows about all processes on all nodes (not just the mother
superior) and can therefore both track and kill them if necessary
Just my $0.02...
