I have downloaded some demos and am starting to learn how they work.  I learned that to run it in parallel I need to specify the path for my firedrake version of python

/usr/local/bin/mpirun -np 4 ~/software/firedrake/bin/python burgers.py 

These run in parallel and do seem to take up the right number of cores.  I am curious to do some tests on my laptop, desktop, and cluster to see how things scale.  The actual problem doesn't matter so much but I would like it to be something like Shallow Water, Navier Stokes, or something in that line.

Are there any examples that someone can point me towards that would be good to test parallelization on different machines?
