I have cut out a huge chunk of our project to try to reproduce this problem, but it doesn’t.
On a full project it reproduces every time.
Like I’ve written before - it started happening after introducing a small change that uses cub.h.
Code works, our unit tests pass, cuda_memcheck does not report any problems. But debugger is showing “Could not resolve name” for all variables.
After reverting the change - debugger starts to work again.
After many days of work I have managed to create a minimal (still big!) reproduction case for this problem.
It is available in this archive:
Please see README.md inside the archive for details.

I can repro your issue on my local with your app attached ,thanks zbychs, we will look into this.
Hi cybernoid and zbychs ,
We tried both your project for repro . We can see the "Could not resolve name… "issue in Legacy debug. But we tried that they all should be working in Next-gen debug. And we fixed the demangled types of variables to make them more readable. Thus it can be a quick workaround for both of you.
for cybernoid ,
Win7 64bit, GTX1080Ti & GTX1080, VS2017 15.8.1 (And earlier), NSight 5.6, Driver 398.82
Suggestion is update to R400+ driver (if can be Latest , better), Nsight 2019.3 , win7+ pascal need to turn your pascal into TCC to run Next-gen debug. If you don’t have a spare dispaly for it , I am afraid you have to get a win10 RS4+ that supports both pascal wddm and Tcc for Next-gen debug.
for zbychs ,
Legacy debugger on GeForce 940MX, CUDA 10.1 Update 1, driver 425.25, VS 2017 and 2019.
I am afraid a maxwell can’t do nextgen debug .But I tried your mini projcet (thanks for that) , I can see the varibles you care in Watch (maxPValu/matchingYsForValu/shared_storage_union) display the values except the types are not readable which we will fix in next version. I also tried modify the source/ add another kernel/remane kernel …they can be read anyway .
see the shots what it will look like in next version. Hope this can help you ,thanks.
Hello yni. Thanks for the info.
However you have written that: “I can see the varibles […] display the values except the types are not readable”.
This is not the behavior I see on my side.
The values of the variables are not displayed. Instead of their values I get one of the messages:
See this picture:
If the values were displayed it wouldn’t be a big problem. But since there are no values it makes debugging impossible.
If you don’t reproduce this problem on your side you can either try the exact version of tools I used (I have listed them in README.md), or you can give me versions of tools I should prepare reproduction for. I will try to do this.
Sorry zbychs, your app on my side even in Legacy can show the variables, I tried same config as you on 2019.2.
So I really don’t know how to help you then since you are with Maxwell + legacy can’t do next-gen debug.
My config is
2019.3(2019.2) + Latest Driver + pascal
maybe you can try our latest version 2019.3 + R435 .Good luck to you.
I have updated to newest versions of tools, and the reproduction case doesn’t reproduce any more.
But the bug still does reproduce on the original, non-minified project.
This is not surprising, considering that this bug is very sensitive to practically everything in the universe. It appears and disappears with tiniest changes.
Last time I’ve spent around 30-40 hours trying to get minimal reproduction case for the then-newest tools. That’s almost a week of work. I’m not sure I can afford to do that again.
HELLO,
I have similar anomalous Next Gen debugger behavior when trying to watch local and parameter variables. As I execute the code through breakpoints in VS 2019 sometimes some variables show expected values, sometimes not at all, or sometimes the wrong values, even when they are in scope. Sometimes breakpoints are hit twice when the next one should be hit? Even some if statement comparisons are failing even when I verify the values being tested, but I am unsure because of the debug misbehavior. Just wanted to see if anyone else has found other things to try…
Here are the GPU specs on the WIN 10 box…
