> Notes:
>     v3 -> v4:
>       - Format code with Ruff, line width 79 to avoid flake8 warnings
>         (Flake8 is by default configured with line width 79 on my system)

Please keep the default ruff/black settings. And when formatting with 
these tools, flake8 is mostly useless.

If you want to check your code for defects, you are probably best with 
`ruff check` which combines the features of multiple python linters and 
runs much faster.

>     v1 -> v2:
>       - Added commit that sorted output by NUMA node
