Application falls, but debug goes well


I have a problem with a well working code. When I run it with
certain parametres it falls down with the message:

The nvidia openGL driver detected a problem with the display driver and is unable to continue. The application must close.
Error code:3

but in NSight debug mode all is ok and the result is perfect as expected.

I use the GeForce GTX 680 and last versions of drivers and SDK.

What could it be and what can I do to check it?

Thank you.

Falke, It’s unclear if this is a CUDA or OpenGL issue. Can you provide more detail regarding your application, what version of Nsight you are using, and how you are using Nsight.

Thank you for the concern, Greg.

So, I use Nsight VS Edition 2.2 with just an option from Nsight tools list “Start CUDA Debugging”.
Regarding my application: in general it’s kind of image processing, where a 2D float texture is used to store the information. OpenGl is used only for output of the final picture. Therefore I don’t think that problem is there - result is shown in debug mode the same way.

I have found the problem.

It was just a watchdog restriction, I didn’t know about it.
