  • 2K and hyper threading.

    I know XP supports Intel's hyper threading and supposedly 2K does not, but can it work anyway?

    No?!

    I thought that hyperthreading is "transparent" to OS, wchich means that any OS that can make use of dual cpu's can take advantage of HT.
    Was I wrong?

      I meant not officially supported on 2K but does it work anyway?

        No. Win2k will show the 2nd processor, but it cannot distinguish between a physical and a logical processor. You must use WinXP or greater...

              So on a dual CPU win2k server it shows 4 CPUs, but what does it really do with the 'CPUs'

                From what i understand, Nowhere is right...it just sees them as 2 CPUs, and does it's thing.

                  It treats them like they have their own cache, and like they don't need special treatment when they stall.

                  HT is not really two CPUs, and it can act slower than a pure UP if not handled correctly.
