1.5 GFlops/proc is the theoretical peak of the power3 chips used in ASCI
White. That is not 15x faster than the theoretical peak of a 500 Mhz PIII.
The actual performance of both is lower than their theoretical peak.

As far as real computations go, remember that the fastest machine in the
world on the Linpack benchmark, ASCI Red, is #3 in theoretical peak. Cough.

Of course -- it's hard to build a cluster that costs that much for list
price. The FSL system was cheaper than that.
