CUDA Parallel NSight Debugging host and device simultaneously

Question

Does anyone know if its possible to Debug CUDA using parallel NSight on a remote machine? I am able to step into CUDA code but not my host code. It says CUDA has the capability

Answer 1

Simultaneous GPU/CPU debugging from a single IDE instance is unfortunately not possible with the current releases of Nsight and Visual Studio.

As a workaround, you can start GPU debugging from one copy of Visual Studio, then open a second IDE instance and attach its CPU debugger. They won't have unified stepping, but you can at least set breakpoints independently.

Answer 2

It should now be possible to attach both the Visual Studio default debugger and NSight in the same VS instance. Then this should work.
