OK, so I have to do something like:
bsub -n ${CPUS} mpirun myapplication

Is it what I think?

I've enclosed the configure output as well as the config.log. The
problem is that my LSF (I didn't install it) 7.0.3 need libbat to be
linked against llsbstream (I modified the configure script to add
-llsbstream, and it compiled).

I can't use the official way of launching a batch job, LSF doesn't
pickup the correct LSF script wrapper (due to a bogus installation).

Thank you for all the answers! (I will have others, as I'm trying to
use the InfiniPath support as well)
