PETSc/ridgeSim 3D scaling on BG/L

[Matthew Knepley]

Thats awesome. 80% true efficiency for 1K nodes on under
1 million unknowns. Thats only 1,000 unknowns per proc. If
we were cranking the problems size, I am sure you'd be up
in the 90s. Hopefully this summer we can deliver you much
improved serial performance as well. BTW, I want to talk
sometime about the subduction benchmark. Van Keken talked
about it at Purdue, so I got a diametrically opposed viewpoint
from a sympathetic person. It was eye opening.
