Jack Dongarra's "Linear Equations" Benchmarks put an IBM 6000 model
550 (41 MHz) doing Linpack at 27 Mflops (not hand-optimized), which is
equivalent to a Convex, Cray-1S, etc. Of course, hand-optimized it is
"only" 62 MFlops and can't compete with the vector machines.

Does anyone have anything bad to say about it's Flop performance? Is
this benchmark representative of its performance on other benchmarks?
Granted the 6000 is a different animal than the vector machines, but
does anyone buy it anyway for heavy Flop applications because of it's
cost or because its less essential to hand-optimize your code in order
to get decent performance out of it?
