I do neural network research. That means I to an awful lot of
calculations of the form

x= sum(over i) w(i)*o(i)

i.e. multiplies and sums.  I don't care about savages or mandlebrot
tests, and I'm willing to write
assembly code for my inner loops. 

I just found out that I can buy an unbundled 2630 at edu discount if I
act within the next month.

EXACTLY HOW MANY FLOATING POINT OPERATIONS PER SECOND CAN A 2630 BOARD
DO, IF THEY ARE EQUAL NUMBERS OF MULTIPLYS AND ADDS (they can be short
floats, not doubles, if this helps).  I need to know whether my typical
run would be a week (acceptable) or a month (unacceptable) (and you
thought ray tracing was bad!).

Please reply with as much detail as possible  on the floating point
capabilities of the 2630, and please do
so soon.

regards. Michael

p.s. What I really desire is one of these new IBM workstations -
25MFlops, $12000. pretty hot (and I never thought I'd say that about an
IBM thing). But I haven't got $12000, so lets see what I can do with my
amiga.
