When the CPU/OS version display? Are you planning to do it as well?

[hutch--]

The CPUID string and related info is not that important for this particular task, what I am inteested in is the timing of the 4 algos.

Same question again, what OS verion are you running, your display is excluding the later common control manifest.

Same OS as I said before.

Hi,

Cheers,

gratsie all,

I think the algo that Paul Dixon wrote clearly has the legs so the strategy of adding two different algos to the library makes sense. I have verified both Ray's shorter algo and Paul's long one and they produce valid results for the entire DWORD range.

That's great  :U

I have found an unusual effect with the last algo that is in MSVCRT, there seems to be a reasonably large timing difference from one version of MSVCRT to another. Its at its fastest on my XP sp3 box, on the same box with a VM running Win2000 its noticably slower against the others and on my win7 box its slower on an i7 quad.

may be due to added security to prevent buffer over-run
