Older GPUS in this url(https://developer.nvidia.com/cuda-legacy-gpus)

61  Pascal              GTX10

53                      Jetson Nano

### CMAKE toolkit

In case cmake extention cannot find cuda toolkits, add following lines to $HOME/.local/share/CMakeTools/cmake-tools-kits.json, then restart vscode

```
[
  ...
  {
    "name": "CUDA Compiler",
    "compilers": {
      "C": "/usr/local/bin/nvcc",
      "CXX": "/usr/local/bin/nvcc"
    },
    "isTrusted": true
  }
  ...
]
```

## HOW TO DEBUG


### COMPILER ARGS

Remember to add "-G -g" in nvcc commmand line args, or add following line CMakelists.txt

```
set(CMAKE_CUDA_FLAGS_DEBUG "-g -G")
```

### GPUs

Debug on a multi-gpu server to avoid share GPU with X-window, or use follow commands to start in CLI mode:

```
sudo systemctl set-default multi-user.target
sudo reboot
```

If want to change to GUI, run:

```
sudo systemctl set-default graphical.target
sudo reboot
```

### Permission

User must be in debug group, use id command to check, if not, add current user to the group:

```
sudo usermod -a -G debug $USER
```

### DEBUG IN WSL

Use WSL2.0 in Windows 11, install NVIDIA driver in Windows, and check nvidia-smi works OK:

```
/usr/lib/wsl/lib/nvidia-smi
```

And install WSL version CUDA toolkit in WSL from this URL(https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=WSL-Ubuntu&target_version=2.0&target_type=runfile_local)

Add register settings in windows(from https://docs.nvidia.com/cuda/cuda-gdb/index.html#supported-platforms), make sure this capability is enabled via the registry key >HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\GPUDebugger\EnableInterface set to (DWORD) 1. If there is no GPUDebugger entry, create it.
