Actually I got 1 (my brain is stuck in base 3). Firstly, different processors
rarely give exactly the same answer for floating point arithmatic, but thats
not my point. My point is that when _you_ compile code, I assume there is
some level of optimization. I have a Athlon64 at home, my laptop is a P3, my
work desktop is a P4, and our cluster is madse up of dual Opteron boxes.
What's optimized for one isn't necessarily good for the others, which I
believe is one of the arguments for Gentoo. This does however mean that
optimized binaries will be different for each.
