I have some elaborate perl scripts that control a PBS job by iteratively
running a secondary script (which needn't be MD, of course), querying
the PBS API about how progress of the time allocation is going, and
keeping iterating that secondary script so long as there's enough time
available from PBS for the next iterate to finish. You need something
like the script Dallas Warren posted to actually do your MD sensibly,
and you handle the final iterative job re-submission at the higher level
of scripting in my approach. The advantages are that you should never
waste time because your PBS allocation runs out before mdrun returns,
and you get the chaining effect of never not being in the PBS queue.
My scripts require some installation of CPAN modules and require you to
have some moderate knowledge of perl to adapt them to your needs, but
they're available if you email me.
