12:37 <Arnav-Negi> I had a doubt regarding service_executors, I'm working on an old hpx program that usesthem and it uses a method "add"

12:37 <Arnav-Negi> building the program fails and the error says that io_pool_executor has no member add

12:38 <Arnav-Negi> So how do I run a function on an executor now, I'm assuming the interface has since changed

13:13 <zao> Arnav-Negi: Squinting at examples, it seems like you might want the `post`, `sync_execute` or `async_execute` free functions.

13:13 <zao> f.ex. <https://github.com/STEllAR-GROUP/hpx-kokkos/blob/master/tests/executors.cpp>

13:13 <zao> Not sure where the relevant HPX guide-level docs are, if any.

13:14 <zao> Many things in HPX are not member functions but rather free functions as those tend to be more generally customizable and reusable.

13:28 <Arnav-Negi> Ahh yeah I can see some

13:28 <Arnav-Negi> Okay the service executor class has similar friend functions I will look into them thanks

13:30 <hkaiser> Arnav-Negi: the executor interface has to be exposed through tag_invoke overloads for sync_execute_t, etc.

13:32 <hkaiser> Arnav-Negi: see for instance https://github.com/STEllAR-GROUP/hpx/blob/master/libs/core/executors/include/hpx/executors/parallel_executor.hpp#L323-L339

13:33 <Arnav-Negi> Okay so I pass the function in parameter f and arguments in ts with some executor exec

13:34 <hkaiser> look at related tests, that usually tells you the whole story
