…ly associated with CPU cores.
The implementation avoids 1:1 strict mapping between work queues and working threads which is often a far greater number than the number of cores.
This implementation improves handling of cases where the number of workers needs to exceeds the number of cores and causes precipitous performance drops because:
- the cost of snooping/stealing does not grow with the number of workers.
- the local queues tend to be deeper (since there are fewer of them) and thus stealing is less frequent and less contentious with enqueuing/popping.
- reduced likelihood that the workitem will have to execute on a core different from where it was scheduled.
