A great example of why Xeon or Opteron and now PHI and Kepler make a whole lot more sense than Blue Gene or Origin. :) Commodity off the shelf hardware and software solutions continue to make the world go round...............

In a similar vain, I would guess that another straw on the back of Road Runner is the fact that it is a unique design with no next generation or upgrade path.
I also know that I/O rates are an important design requirement for these machines that, of course, is not addressed by HPL rank (but makes for good news stories).
