enum class thread_priority

Description

This enumeration lists all possible thread-priorities for pika threads.

Name	Value	Comment
unknown	-1
default_	0	Will assign the priority of the task to the default (normal) priority.
low	1	Task goes onto a special low priority queue and will not be executed until all high/normal priority tasks are done, even if they are added after the low priority task.
normal	2	Task will be executed when it is taken from the normal priority queue, this is usually a first in-first-out ordering of tasks (depending on scheduler choice). This is the default priority.
high_recursive	3	The task is a high priority task and any child tasks spawned by this task will be made high priority as well - unless they are specifically flagged as non default priority.
boost	4	Same as \aexcept that the thread will fall back to \aif resumed after being suspended.
high	5	Task goes onto a special high priority queue and will be executed before normal/low priority tasks are taken (some schedulers modify the behavior slightly and the documentation for those should be consulted).
bound	6	Task goes onto a special high priority queue and will never be stolen by another thread after initial assignment. This should be used for thread placement tasks such as OpenMP type for loops.
