Returning immediately with whatever state the long-running computation
is in currently seems indeed to be a good solution.  I think I will
setup something similar.  Would you share your experience on the
following issues?

- How do you interface such jobs from orgmode?  With org-babel, do
  you execute Python code, or do you run shell commands?

- Do you run your Emacs on the master node of the cluster?  Or does your
  setup involve running emacs on the machine you are working on and
  talking to the cluster over the network?

Cheers,
Christoph
