<pansysk75[m]> i want to examine the behavior of scan_partitioner... (full message at https://libera.ems.host/_matrix/media/r0/download/libera.chat/de39f879dca33e1adf78b73b98c92260182f97e4)
<hkaiser> std::cout should output as expected
<hkaiser> to make iostreams available you need to add hpx_iostreams_component as a dependency
<hkaiser> pansysk75[m]: i.e. the HPX::iostreams_component target
<hkaiser> pansysk75[m]: for the instrumentation - you probably want to look at the scheduled threads, you can see an example on how to do that here: https://github.com/STEllAR-GROUP/hpx/blob/master/examples/quickstart/executor_with_thread_hooks.cpp
<pansysk75[m]> <hkaiser> "to make iostreams available..." <- Aha, I'm familiar doing this when I'm building a project that is using HPX.
<pansysk75[m]> Now the difference is I was trying to add hpx/iostream in existing HPX source code.
<hkaiser> pansysk75[m]: ahh, that would create circular dependencies
<pansysk75[m]> Ok, I guess that's not the way to go then
<pansysk75[m]> <hkaiser> "pansysk75: for the instrumentati..." <- Giannis sent me this, a few things are still unclear about how to use this to output relevant information
<pansysk75[m]> Will come back with questions on this soon
<hkaiser> pansysk75[m]: that example allows you to specify two functions: one that gets called whenever a (relevant) thread starts executing and one before it exits
<hkaiser> you can use those to do timing/annotation/etc.
