SpaceX is doing the best work on simulation. The adaptive multiscale work is a million times more important this moving to GPU, but of course they did that too:

Looks interesting. It looks like they are creating the CFD software for their own specific application. While that's cool and all, I doubt any other companies have the resources/motivation to write complex software from scratch, let alone underfunded postdocs.

I'm wondering about all the research that goes on in all the universities where large investments have been made on CPU based clusters. The simulation in the article you linked was run on NERSC servers, which are Cray supercomputers[1], which pretty much are Intel Xeon class servers with fancy interconnects.

So looks like it is CPU based, but I'm still interested in the software they use.
