[rescue] high memory bandwidth machine?

[nate]

I figure you guys probably know more about this off the top of your
heads than I can find searching product datasheets all day. Didn't find
any nice comparisons of memory bandwidths searching google :( My Dad is
asking me for suggestions for what sort of computer would be best for
running his wonderful Fortran program on. Currently he uses X86 boxen (a
P-IV at work because that's what they gave him, and Athlon with 200mhz
ddr at home...). The bottleneck on every machine he's used since a 486
has been the memory bandwidth - the only speed improvement since the 486
has been exactly the same factor as the increase in memory bandwidth
(no, the dataset doesn't come close to fitting in cache). I looked at
the current RS/6's, but they only claim 100mhz x 128bit memory bus which
by my calculations is half what 200mhz DDR in the Athlon does? Are there
any fairly cheep (try $10-20k at the most) workstations that have
significantly higher memory bandwidth than a current PC? Video is
irrelevant to his app :)

Thanks for any suggestions,
Nate Grady
