[Yt-dev] Parallel Hop

[Britton Smith]

I'm not sure I have any better ideas than what's been presented.  Matt's
padding formula sounds as good as anything.  Since we don't really have a
good idea for how to define the padding that comes from first principles,
maybe it would be helpful to do a small convergence study where we run some
unigrids with varying box size and topgrid resolution, and then varying this
padding parameter.  Maybe from that we will be able to draw up some crude
formula that will help people choose the right value for this parameter.
I'm about to do a bunch of unigrid runs for my own work, so I would be
willing to do some of this.

Forgive my ignorance, is there a sample script or something somewhere on how
to use yt_hop in parallel?
