Detecting number of CPUs

[Clairvoyant1332]

I've searched through the VB.NET documentation, but couldn't find any way of detecting the number of CPUs (logical or physical) on a system. Anyone know how to do this?

A little off topic but I would look at the threadpool class. This discusses it in very basic terms:

I didn't look at all of this, butthere looks like there may be some info here that will help you:

Some interesting reading on thread classes, but it doesn't mention anything about processors. I've alredy written a program using the Thread class, but I currently hardcode the number of threads I'm using, and would prefer to optimize that number based on available hardware.

Hi,

This should work on windows NT and higher (It works on my xp machine anyway):
-----------------------------------------------
MessageBox.Show(System.Environment.GetEnvironmentVariable("NUMBER_OF_PROCESSORS&quot)
-----------------------------------------------
