I have search alot all the thing about CUDA...
On nvidia's forum about CUDA is said that if you have one gpu cuda enabled you can only run a task of CUDA code for about 5 secs due to a background windows process called Watchdog...
That means that windows and all the graphic stuff need the gpu for their own reasons and you cant have unlimited access to the computing sources of your card.
But SETI@HOME manages to run all the time the CUDA code without any limitation...
Any ideas on that?

Thank you

Watchdog is a program that comes with Supermicro brand motherboards and servers (it may come with others, I'm not sure). Most standard workstations and home computers do not come with Watchdog installed. Watchdog is not a program that is packaged with Windows.
