Aw, but I'd claim all that fancy 3-D graphics stuff is real
computation :-)
But yeah, GPU abuse for general purpose computation is just plain
scary. I thank my lucky stars that there is plenty of FLOPS to go
around in the Cell's SPUs.
Eh, nvidia's working on making the GPUs more accessible (via
compilers, kind of like Cell) for more general purpose computation.
The problem with FPGA, GPU, and "non-local" coprocessing cores is
usually the moving of data to them fast enough. Cell shouldn't have
this problem and with the new hypertransport stuff coming out, it
looks like one can easilly do NUMA like things inter-chassis too.
I don't know if this is cost effective, but streaming parallelism to
special coprocessors can be a big win in HPC.
