Sticking my neck out even more, but maybe that problem can be solved
by using the actual Teraflops as opposed to peak-teraflops? I'm
curious, how good are these GPU based systems when solving something
like the Linpack or the SPEC benchmarks? Of course, I'm not saying
either of these benchmarks are representative of a "real-world" load.
But perhaps they are closer than a peak-teraflops metric.
