Recently I've been reading about General-Purpose Computation Using
Graphics Hardware - http://www.gpgpu.org - and it seems that GPUs can
bring quite a good performance when compared to the CPUs.


In other words, a graphics chip on the graphics card can make really
heavy computations, and it's easier and cheaper to buy a couple of
top-performance graphisc cards than to buy a multi-CPU machine (which
are quite expensive).


Do you think - theoretically - that a compiler could help compiling
software, which would in turn use the power of the GPU to make some of
the computations?


Like now we have compiler options like "-mmmx -msse -msse2 -msse3
-m3dnow" - would it be possible to optimize the code of the binary to
use the GPU with "-with-nvidia-gpu" or "-with-ati-gpu"?


I would like to hear some theoretical discussion about that.
