Dear Tomasz,
  if you want run on 6 cores for the moment you have to submit 6 jobs.
(and you must take care of changing the random seed in the inp file)

With Flair you can already "spawn" (split it in many sub-jobs) each
with a different random seed.
The binaries of the subjobs will be automatically "belong" to the job
you spawned and can be easily be merged together.

There is a script done by (check it on the list
