Signal Processing on GPUs - Sony funding Nuclear Weapon Design?

The Stanford University Graphics Lab has a program called BrookGPU, which offers a high-level and C-like programing language called Brook. This may be interesting for anybody wanting to do signal processing on GPUs (Graphic Processors).

Now the other thing is, that the site names as sponsors IBM, SONY, ATI, NVIDIA, DARPA, and DOE and that the related Merrimac - Stanford Streaming Supercomputer Project has the intention to build a even faster (and cheaper) supercomputer.

Now do I hear anybody hear say "Atombomb design"? And yes a document states that "verifying nuclear weapons, performing signal intelligence" and "the design of nuclear devices" can be done better on such a machine.
