Really?
"I was a bit surprised by this. I figured that the liquid cooling would yield a better flop/watt ratio vs. the air cooled systems.
However, my analysis could be flawed. I don't have figures for exactly how much power each team was using for the LINPACK run they submitted. All I know is that they were using an amount that was less than the 3,000 watt power cap."
So you assumed 3kW for all of them and are surprised that the GFlops delta is mirrored in the GFlops/3kW delta?
