Re: [hpx-users] parallel_executor::post dominating APEX trace

Kor, I think you've just found a bug (all my fault...) at a very good time. There are indeed configuration options that affect how the scheduler steals tasks and it looks like I've set them to very inappropriate values. Stay tuned for a PR. On the second point you're probably seeing your

Re: [hpx-users] parallel_executor::post dominating APEX trace

Hi Kor, hpx::parallel::execution::parallel_executor::post is what eventually gets called if you use hpx::apply (or future::then) to create tasks. post itself should not take up much time, even in extreme cases. It's hard to say for sure without more information about your application but

Re: [hpx-users] Link error building HPX with support for APEX

I think the real problem here is that the latest HPX release actually pulls latest APEX develop, and not the tag we specify. Specifying a tag is supposed to avoid situations exactly like this but that doesn't work (master may sometimes not work until the dependencies have been updated in APEX,

Re: [hpx-users] Contributing to HPX

Hi Ahmed, One thing that you could work on is adding more (CDash) timing outputs to our benchmarks. John already started this with https://github.com/STEllAR-GROUP/hpx/pull/3421 and https://github.com/STEllAR-GROUP/hpx/issues/3422. I know this is not necessarily technically very challenging,
