Lunatics MB opt apps limited to counting 16 CPUs?

Claggy:
My Atom N450 also reports on r246 as only having one core (it should be one core plus one hyper-threaded core):

Raistmer:
yes, this feature looks broken and better to remove it in new rebuild.

both new and old builds disagree with x64 one

Most of my v6 results show 8 x 3400 MHz, but one shows Speed: 8 x 3421 MHz and another shows Speed: 8 x 3394 MHz , so what is reported swings around a bit.

Josef W. Segur:
Feature detection in the Lunatics builds is mostly based on Microsoft example code for using the intrinsic __cpuid() function, see e.g. http://msdn.microsoft.com/en-us/library/hskdteyh(v=VS.80).aspx. Speed detection is added using rdtsc, IIRC.

As has been noted, that's basically cosmetic for now. If we ever get around to using some of that information to choose paths within the processing, it will be necessary to try to make it accurate and keep it up to date.

V8 only seeing 1 core with correct speed.
