Cuda debugging using Single GPU with visual studio

Question

I am working on Windows 7, Visual studio 2010.

Can we debug cuda code using single GPU which also providing display to the monitor in the same PC? What tools are available ? NSIGHT seems to be working with two GPUs.

Answer 1

Windows 7 support has been dropped in newer versions of Nsight, (see here) basically anything that was released in 2020 or newer. So you're stuck with older versions. Older versions will also have a support chart like the one I previously linked which explains the supported debug scenarios. Generally speaking, single GPU debug as you describe should be possible with a "newer" GPU like Kepler or newer.

The last Nsight version that supported Win 7 is 2019.4 and the associated documentation indicates support for single GPU debugging.

Note that in the 2019.x timeframe, the Nsight tools had both a "legacy" and "next gen" debugger, and the one you should use will depend on which GPU you are using (and possibly driver model WDDM/TCC), see here.

Also note that the last CUDA toolkit that had official support for VS 2010 was in the CUDA 9.x generation.
