A good quite quite https://developer.apple.com/news/?id=vk3m204o > Statically pre-assigning pieces of a parallel workload to worker threads will leave threads idle before the end of the execution. This is because not all cores are equal and so worker threads will not make identical progress. Instead, subdivide parallel problems into a large number of pieces and use a work-stealing algorithm to balance these pieces across threads to keep all workers busy. -- This is an automated message from the Apache Git Service.
