T.C. Sottek, The Verge:

The supercomputer is built with more than 235 Cray XE6 cabinets, using AMD Opteron 6200 processors, and will also utilize more than 30 cabinets of an upcoming Cray XK6 computer with Nvidia Tesla GPUs. Blue Waters will take about nine months to install, and its creators hope that it will allow researchers to create breakthroughs in multiple fields of science - the university says that it will help study things like the formation of the cosmos, the behavior of hurricanes and tornadoes, and other highly complex systems.

I’m imagining a very big computational domain for a large eddy simulation - or even better, a direct numerical simulation - with very small grid spacing. Unfortunately, while the possibilities are limitless, I’m sure project budgets are not.
