Response to: Flop calculations are off
Yes, but those are single-precision calculations. As such they probably won't be that useful to most people doing high-performance computing.

  Its a matter of algorithm design, if you can split an algorithm into two single precisions streams, and then just do the final combine in double precision you can get some mighty mighty mighty impressive performance from a G5
  
  Often double precision is only necessary because two inputs have massively different scales. If you are working with similarly scaled numbers then you can get away single precision... and then just use the double precision for recombining the various scales.
