hyper-threading

Hyper-Threading Technology makes a single physical processor appear as two logical processors; the physical execution resources are shared and the architecture state is duplicated for the two logical processors.

So, this means that there are two sets of basic registers such as Next Instruction Pointer, processor registers like AX, BX, CX etc physically embedded in the micro-processor chip,

OR they(arch. state) are made to look two sets by some low level duplication by software/OS.

There is a number of ways to catch mouse or keyboard under Windows. So I tried some of them, but every of them has some advantages and drawbacks. I want to ask you: Which method do use? I've tried these: WM_KEYDOWN/WM_KEYUP - Main disadvantage is that, I can't distinguish between left and right-handed… >>> More

There seems to be significant confusion about Hyper-Threading. Part of the problem is that vendors like to tout every new feature as the greatest invention since the six-pack, and its follow-on the 12-pack. I used to think the 4-pack was a travesty, but now that I am older and can nolonger finish… >>> More
C/C++/Assembly Programatically detect if hyper-threading is active on Windows, Mac and Linux

I can already correctly detect the number of logical processors correctly on all three of these platforms. To be able to detect the number of physical processors/cores correctly I'll have to detect if hyperthreading is supported AND active (or enabled if you prefer) and if so divide the number of… >>> More

Hey all, With the new Xeon CPUs supporting Hyper-threading, what is the current wisdom with regard to using it (or not) on a Hyper-V host machine? I was originally under the impression that turning it on in a virtual host environment could be detrimental as the 'extra' CPUs were not true cores.… >>> More
