Howto test if the Code is really running on the GPU?

Discussion created by Peterp on Feb 6, 2009


how can i test if the code i wrote is really running on the GPU? I downloaded the SDK set up everything correct. I wrote a very simple Program and compiled is with brcc, then i wrote a little C++ program with VC++2008 and put all things together.  But if i execute the program the Catalyst Control Center(ATI Overdrive) shows no GPU-Activity to me? Of course the program calculates the right thing but i'm not sure if on the CPU or GPU.
