Do tasks performed on the GPU adversely affect graphics performance?

Question

I never programmed a GPU, but finally got an Nvidia card for experimentation. However, the indicated card also controls my monitor. My question is whether working on general general purpose tasks on a map will negatively affect graphics performance. Can such tasks knock out a card? If this is not the case, does this mean that the card has an OS or some other artist on it?

Answer 1

The long-term computing tasks of the GPU may not cause the card to crash, but (Windows Vista / 7), if it works for too long, a system will crash. Windows (at least with Vista) detects a timeout and recovers by resetting the GPU and some state in the graphics stack.

Bing for "gpu timeout" or see this article for example. http://www.microsoft.com/whdc/device/display/wddm_timeout.mspx
