I see mine says: 1165.64 million ops/sec So, that means I'm doing 1.16 giga FLOPS? Thats wild! How do they measure FLOPS for supercomputers. Cause I thought the Cray II only did 1 GFLOP? Is there a good benchmarking program out there to give you a good FLOP estimate? And is 1.165 GFLOPS good for a laptop 1.4ghz Pentium M? Blackhole forums - technology, politics, computers |

> I see mine says: 1165.64 million ops/sec Mine is 1301 Double precision, 1766 integer ... so, you are in the same ballpark > So, that means I'm doing 1.16 giga FLOPS? Thats wild!

Well, there has been a good deal of discussion as to what Giga means ... As far as benchmarking goes, the short answer is NO. There are lies, darn lies, and benchmarks. > And is 1.165 GFLOPS good for a laptop 1.4ghz Pentium M? 3.9 would be better don't you think? :) But it sounds ok to me, for what that is worth. |

Sorry to chime in after a day and change, but gigaflops are now at the consumer level. Apple had a huge ad campaign when the G4 towers came out - Something on the order of "the Pentagon has declared the G4 a weapon because it can process a billion instructions a second. Pentiums are still harmless." Your numbers are fine. Keep crunching. :-) |

As a side note, all of todays chips are operating in the microwave S-band (typical microwave oven operates at 2450MHz). Over 4GHz it will be the into the C-band. I'm not sure why I found that interesting, or why I wasted your time with it. Still looking for something profound or inspirational to place here. |
