Completes #3003.

Proposed Changes

  • Add a section to the manual on how to suspend and resume the runtime, and a short motivation on why one might want to do this
  • Move thread_pool_base out of the detail namespace as it's part of the public API
  • Document member functions in thread_pool_base related to suspension
  • Update docs CMakeLists.txt and hpx.idx to include new documentation

Note: all non-suspension related functions in thread_pool_base are still hidden in the documentation as I'm not sure how many of them should/would be used by a normal user. Most of them will need to be documented eventually though, but that's independent of this PR.

Just a minor comment, looks good otherwise!


In some applications it is required to combine __hpx__ with other runtimes. To
support this use case __hpx__ provides two functions: [funcref hpx::suspend
`hpx::suspend`] and [funcref hpx::resume `hpx::resume`]. [funcref hpx::resume

This looks like a typo. Did you mean to write [funcref hpx::suspend at the end of this line?

Line 193? Yes, that's intentional. Maybe the linebreak looks odd in the middle of the funcref thing but boostbook handles that well.

No, I'm pretty sure you meant suspend and not resume at the end of this line. Suspend blocks, resume doesn't.

Essentially, what's written is this:

[funcref hpx::resume hpx::suspend] is a blocking call which will wait for all scheduled tasks to finish executing and then put the thread pool OS threads to sleep.

@sithhell you're very much right, I was blind. Thanks for spotting that!
