Matrix multiplication is the critical operation, and we could probably live
with 2 25Mflop boards, as long as we could effectively use them in parallel.
We'll be feeding them with a Sun-3/280 or SparcServer 330, so they need
to be 6UVME (preferred) or 9U boards that could coexist with the Sun memory
bus compatible.
I'm famimiliar with a Weitek-based board from Mercury, and there seem
to be several DSP-based solutions out there (are 96000-boards avilable
yet?) single precision and maybe even fixed point seem to be OK.
Is such a beast obtainable for around $50K? I expect that the VMEbus
performance of the Sun may be the limiting factor.
