MultiThreading and Dual Core

[arunairs]

Hi,
In a multi-threaded app on a dual core machine, is it possible to
know on which cpu a particular thread is currently executing on?

thanks,

Arun

You can PInvoke some Win32 functions to get that information; but why would
you want to?

No, because it can change at any time, including during the call to the
function that would find out.

I am comparing the performance of my code ( multi threaded, cpu
intensive) in a single core and dual-core systems and only see a
performance gain of around 15%. This led me to wonder if the runtime
was actually using the dual core. Hence I was wondering if there was
any way I could find this out.

Alternatively, is there any way to get the usage statistics of both
the cores within my program?

thanks,

Arun
