Hi everyone,

thanks,
cheers,

With CUDA 2.1 you can find out if device is connected to monitor by calling cudaGetDeviceProperties() and checking kernelExecTimeoutEnabled field of cudaDeviceProp structure. If it is 1 then watchdog timer is active and device is connected to display.

AFAIK there’s no way to achieve this before CUDA 2.1

thanks,

I have installed CUDA2.1, but I can’t find kernelExecTimeoutEnabled field of cudaDeviceProp structure.

It is there, at least in Programming Reference Manual :)
