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?

Mine is 1301 Double precision, 1766 integer ... so, you are in the same ballpark

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.

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. :-)

If you had the brains to make a worthwhile cluster out of them, you'd just build your own chips, it would work better. 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.

Well, how about this? My microwave opens up the automatic Dog door in my kitchen ...
