Excellent. Thanks Gus. That sort of estimate is exactly what I needed.
I do have AMD Athelons.
In fact, this is super usefule for some of our oldest legacy hardware
too. We used to just use Dell Desktops clustered together. I have
easily accessible all the other info. that goes into your equation.
Except the floating point operations / cycle numbers.
Let me dig those out.
