[Solved] How to find the number of CPUs as reported by Task Manager


Recommended Posts

Hi I'm looking for a function that will return the number of cores present on a PC and if the processor has Hyperthreading the number of CPUs as displayed in Task Manager.

For example:

2 core processor without hyperthreading would return 2

4 core processor without hyperthreading would return 4

6 core processor with hyperthreading would return 12

8 core processor with hyperthreading would return 16

I've been searching the forum and example scripts and not found what I'm looking for so far.

If someone knows of such a function Id be greatful for a pointer to it.

Thanks

Something like this perhaps?

The scriptomatic tool makes it easy to come up with this kind of script, all I needed to do was to eliminate all the other crap that's known about the processor to get to this. :)

Thanks Guys

"NumberOfLogicalProcessors" was the name I could not remember. Now that I know what I was supposed to be looking for I found a function similar to the one given by BrewManH on my PC in a script I wrote 3 years ago.

I think I need to get a new search function for my ageing brain.

Remark: NumberOfLogicalProcessors is only available on Vista+ operating systems.

Br,

Please don't send me any personal message and ask for support! I will not reply!

Here's some follow-up information in regards to what UEZ mentions:

Windows Server 2003, Windows XP, and Windows 2000: Because the NumberOfLogicalProcessors property is not available, NumberOfProcessors indicates the number of logical processors available in the system. In the case of a computer system that has two physical processors each containing two logical processors, the value of NumberOfProcessors is 4.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

The NumberOfLogicalProcessors property is available on some versions of XP. I just used it on several PCs at work (XP profesional SP3) and the expected values are returned without any errors. I believe Microsoft made this available to XP in SP3
