My laptop has 14 physical cores, confirmed by feature('numCores'), and doing pool = parpool() starts a pool with 14 workers on R2023b. However, on R2024a on the same machine it starts a pool with only 6 workers, and feature('numCores') still says there are 14 cores.

The documentation I can find still says that the default number of workers is equal to the number of physical cores. I can't find any settings anywhere that are not set to the default values (or blank).

Is this an undocumented change in behavior? Or am I missing something?
