Windows Server 2003

Does that OS support Hyper-Threading Technology?

Thanks

I hope I'm not showing my igorance here, but I was under the impression that Hyper-Threading is "black-box" technology contained within the CPU itself and is not something an OS or App must be written to use. I am also thinking that "threading" in an OS (executing seperate functions within a process "simultaneously") is not the same as CPU threading (managing several instruction queues).

As always...if I'm wrong I'll disavow any knowledge of this post. Good luck Mr. Phelps! 😀

Technically a HT CPU will show up as 2 CPUs to non-HT aware OS so it will work in a fashion, but since the OS think there's 2 physical CPUs it schedules process as if it was running on a 2 CPU machine, but that's not true and the processes usually end up fighting over resources.

 

I think my question is does Server 2003 support HT as XP SP1 does? Another words, is it (2003) optimized for HT?

Yes.
