I have a list of CPU-bound tasks I need to perform. I'll list two of
them here:
a) compute first zillion digits of pi (low priority)
b) add two plus two (high priority)
I co_spawn (a). Later, while (a) is running, I co_spawn (b). (a) will
be suspended at a "co_suspension_point" so that (b) can take over. Of
course when (b) completes, (a) will resume.
For bonus points, it will support multiple threads (probably easy) and a
task's priority can change over time (probably hard).
Scheduling coroutines is in Boost.Fiber's wheelhouse. I don't think it
provides a priority-based scheduler out of the box, but it does discuss
it as a customisation point at:
