Well, lots of things are 'claimed' in marketing (and Wolfram is not
shy to claim). I think that you need lots of GPUs, as well as the
right problem.
Which makes me wonder whether R would be able to make use of this
processing power, since the figures claimed by Wolfram are very
probably for single-precision floats? (Am I right in thinking that R
only works with double precision?)
According to the nVidia Web site, the Tesla architecture is _ten
times_ slower for double-precision operations than for single-
precision, which makes it seem far less amazing than at first sight.
