The researchers at the University of Antwerp's Vision Lab
caused quite a stir last
year when they built a supercomputer with four high-end NVIDIA graphics
cards, but it looks like they've truly stepped up their game for their
followup: a supercomputer that packs no less than thirteen GPUs. That, as you
might have guessed, presented a few new challenges, but after wrangling some
flexible PCI cables into a specially-made case and loading up a custom BIOS
courtesy of ASUS, they were apparently able to get six dual-GPU NVIDIA GTX295
cards and one single-GPU GTX275 card up and running with only a few hiccups. As
before, the big advantage with this approach is that you get an enormous amount
of computing power for a relatively small cost -- twelve teraflops for less
than €6,000, to be specific.
