CPU usage bounces on the interval [140%, 380%], resulting in idle cpu resource above 60%

Is there a command line argument for specifying degree of parallelism?

Some feedback, maybe got fixed by some other changes.

Running the code from Jun 27th, 2024, I have seen this with an m2:

It's still running and it's always 600%+ so far.
