kernel exec timeout

Hi, is it possible to disable the kernel exec timeout and set a longer kernel exec timeout value?

When I increase the number of loops running on the kernel, a message will popup from windows task area saying the Display Driver has no response and has been restarted. It seems to do with the kernel execuation timeout value.

Thanks

Yes, you can set it via a registry setting (search the forums for “watchdog timer” or “TDR”). Keep in mind that if the card in question is driving your display, it’ll freeze (and the machine will be totally unresponsive) until the kernel is finished running. For obvious reasons, changing this registry value isn’t something you should rely on (can you break your kernel into smaller chunks and call them individually?)

Thanks for the reply.

The card we use is GeForce GTX 296 and is on Windows Server 2008 R2 box. It does not seem to have the registry key mentioned in the msdn.

If we choose to unselect this card as the display adapter, will it avoid the time out problem?

Hi I think I’m having this kind of trouble here.
What can I do to avoid driver reinicialization?
My kernel code need a lot of time do run…
