sigh. Apple bought a benchmark. does this make Apple products better?
> BigMac G5 (aka "X") (2200 CPUs) - 10.3 TFlops
OK, so we already know that their pricing disclosures are ah,
"optimistic". (nodes probably cost >6k apiece, not half that)
and their yield is around 59%. not to mention the little bit
of missing ECC...
actually, I'd love to know what their yield is if they had only
4GB per node - almost certainly lower.
> Lightning (LANL Opteron) (2816 CPUs) - 8.1 TFlops
yield is 72%.
> Apple BigMac is number 3, while the Opteron cluster is
> number 6.
for the billionth time: rmax is just a matter of how much money
you have. rmax/rpeak is the only part of top500 that matters.
I'd like very much to know the actual prices and discounts for Big Mac.
it's a shame this isn't required for Top500...
