Very interesting, but perhaps a bit of an overkill. How many TFlop/Watt does

If I'm not mistaken, the Tsubame cluster was initially using
Clearspeed accelerators (in Sun X4600 fat nodes).
Therefore, they probably have appropriate programs that need little
adaptation (or less than many) to work on the GPUs.
