Just in case people are curious - I think this is a really powerful feature of

openlane2

- the python

multiprocessing

module works fine when deploying a classic sequential flow. It means you can generate hundreds of chip variations pretty fast with a large machine which was more complex to do before! I'm also thinking of other distributed computing speedups that the Python environment might enable if you have any tips. I've done a little demo here integrating openlane2 within a larger design flow, and am excited by the results! https://piel.readthedocs.io/en/latest/examples/02a_large_scale_digital_layout/02a_large_scale_digital_layout.html
