How to debug CUDA kernels in Visual Studio 2010 without monitor halting

Question

I have CUDA 6.5 SDK with Parallel Nsight 4.2 installed on Win7 x64. I want to debug my CUDA kernels, but my monitor halts at break points.

In my Nsigt montior options under CUDA menu I have

Desktop GPU must use SW preemption: true

Headless GPU must use SW preemption: true

TCC GPU must use SW preemption: true

And in my VS 2010 Nsight Cuda options I have

Preemption preference: Prefer NO SW preeption

I tried SW preemption in VS 2010 Nsight settings but same thing the monitor halts.

It's not related with code because I was able to debug in Linux using nsight eclipse using the beta feature to be able to debug using 1 GPU.But I prefer to work in Windows.

Answer 1

In Nsight Monitor settings in Geenral tab I changed

WDDM TDR enabled to false and now it seems to be working.

I am using NVIDIA GTX 970 GPU and NVidia Driver 344.75.
