Hello! Thank you very much for the reporting this issue.

Could you provide some additional information:

  • cuda-gdb version you are using (output of cuda-gdb --version command).
  • nvidia-smi command output
  • deviceQuery sample output

Also if you are not using the latest CUDA-GDB version, could you check whether this issue is still reproducible with the latest CUDA-GDB: CUDA-GDB | NVIDIA Developer
