I have two nVIDIA display cards on my VISTA computer “Quadro FX 1700” and “GeForce GTX 260”.
I want to use “Quadro FX 1700” for display only and “GeForce GTX 260” for CUDA only.
I made “Quadro FX 1700” my primary display and “GeForce GTX 260” my secondary display. I set the device using “cudaSetDevice(1);”. But again my computer hangs if the kernel takes more than 5 seconds to execute. Why is this happening as the kernel should run on the secondary device and primary device should keep working without any problem.
Any help/suggestion would be greatly appreciated.
