[Beowulf] Nvidia FERMI/gt300 GPU

[Bill Broadley]

Impressive:
* IEEE floating point, doubles 1/2 as fast as single precision (6 times or
  so faster than the gt200).
* ECC
* 512 cores (gt200 has 240)
* 384 bit bus gddr5 (twice as fast per pin, gt200 has 512 bits)
* 3 billion transistors
* 64KB of L1 cache per SM, 768KB L2, cache coherent across the chip.

No time line or price, but it sounds like a rather interesting GPU for CUDA
and OpenCL.
