Very interesting.
If feasible it could also be applicable to the linux playstation 2 powerful
GPU.

Just wondering if any of you Linux wizards are aware of any successful
work in writing drivers that effectively turn a graphics card into a
processor, parallel to the CPU. The ideal would be drivers that let the
parallel co-processing be done "transparently" to the end user, so the
graphics card is turned into virtual CPU without further intervention
by the user.
I do some rather heavy numerical calculations on my PCs and would
really appreciate the FLOP boost parallel processing on GPUs can offer.
I've read some articles from gpgpu.org about splitting the single
precision tasks on the GPU (all GPUs AFAIK are SP) and double precision
on the CPU, but no "transparent" user level drivers were mentioned.
I don't think it can be done transparently. You'd have to re-implement
your software to take advantage of the GPU. In addition to the site you
mentioned, there's also http://libsh.org/
