this is good news for bringing big computing iron back into the hands of regular students. this is a lot of cpu for 5 mil, considering that the 36 (iirc) Tflops Earth Simulator was a billion.

To note, the last LINPACK spec they released was putting them just over 9.5 Tflops, which is nothing to sneeze at, but nowhere near 80%. Some predictions don't show them getting much above 60% of theoretical. Of course, they're still 2nd or 3rd on the Top100 list, so that's pretty neat. Also interesting, they are running MacOS, not Linux.
