[Beowulf] What happened to AMD GPU?

The one thing NVidia did right was port/support popular
applications to CUDA (Amber comes to mind). I don't see
how AMD can compete in this space if they don't do the
same thing, but do it for their APU Opteron-X processors
using HSA  (should they come out with some heftier models)

> Not as fast as a K40, but beats other cards.
