    We previously discussed the matter on GitHub, and after conducting further tests on profiling the SSB-SF100 query using a single plate number for video and computing, we observed that the GPU usage is causing instability.

    Our suggestions are as follows:

    1. Use the 535 Driver at a minimum. In the 7.1 release we changed the way the memory is allocated in the GPU, so using a driver version older than 535 can cause performance issues.

    2. Check whether the system has enough memory to accommodate the GPU memory dump during profiling. If there is a memory shortage, close memory-intensive programs such as VSCode, retry, or cut the SF of the benchmark.

    3. Run the profiling and switch to text mode. On Ubuntu, switch to a text virtual terminal by pressing Ctrl + Alt + F3 (you can use other virtual terminals by changing the F3 to F1, F2, etc.).
