When I argue that many other computational electromagnetics programs such as
FEKO <http://www.feko.info> can run in batch mode without any X output and
can be sheduled directly by external job queueing system, engineer from CST
declares that kind of program not starting a GUI is old-fashioned...
Are they telling the truth, or just lying?
normally, it's the solver that uses MPI, not the gui. so the gui
will set up jobs, and submit them to the cluster's queue, but itself
really only runs on a "login" node. this is mainly motivated by a
concern for the user's workflow, as far as I can tell - desire to make
it as IDE or "studio"-like as possible.
in the several similar packages I've integrated, there are usually
some sort of hooks available for determining the exact commandline
for submitting a job. after all, even if assuming LSF, a particular
site will often have idiosyncratic parameters and switches. normally
these hooks can be transformed into using completely different
submission commands (though in the worst case, you could just write
a quick "bsub" emulator that did the right thing for your cluster.)
