Microsoft said Thursday the next upgrade of its Windows Server operating system will scale up to 256 logical processors. Microsoft defines a logical processor as the number of physical processors multiplied by the number of cores as well as the number of threads, said corporate vice president for Windows Server and solutions, Bill Laing, during a keynote speech at the company's Windows Hardware Engineering Conference (WinHEC).

Thus, Windows Server 2008 R2 will be able to, for example, support a system with 64 physical processors each with 2 cores, each supporting 2 threads (64 x 2 x 2 = 256), said Laing. Windows Server 2008 today supports up to 64 logical processors.

So that's what this is all about then!

"Microsoft defines a logical processor as the number of physical processors multiplied by the number of cores as well as the number of threads"

Um, no. Learn how to do basic math, please.

A board that has two quad core Xeons has [4+4=8] eight logical processors, not [2x8=16] sixteen.
(And for those of you who don't know, Xeons are not hyperthreaded... yet.)
If you want to know how many logical processors you have, total up the core(s). {If the core(s) are hyperthreaded) multiply by 2}. That's all you need to do. This is not rocket science.

it should be the number of logical cores not the threads

btw
to hit the limittion

you only have to own

upcoming intel 16Xbeckon(8 core processor which is capable of 16 logical core )

proc 16X logical cores 16 = logical 256 cores
