<jbjnr> taeguk- not that I'm aware of.
<jbjnr> There is the return type from the parallel algo's that does something similar in terms of type checking, either a future<T> or a T depending on asyn/sync launch

<pree> why pure virtual's cannot be actioned ?
<pree> If there is any reason ?
<pree> I don't any on both sides.
<pree> thanks

<pree> clientA(client to A) instance of B what does it mean ?
<pree> something specific to HPX as dealing with components
<pree> ??

<pree> whether Actions are inherited alike functions in components ?

<mbremer> Hi, I had a question regarding HPX stack overflows: I am writing a stencil based stepper code, so the messages get processed as futures. When I try to declare the receive futures vector outside of the main loop ( see line 6 in https://gist.github.com/bremerm31/e91581b3248b15a686f9b0d722855c33 ) I seem to be getting stack overflows. If I just keep the receive futures within the scope of the continuation (like so https://gist.github.c
<mbremer> I don't seem to be having any issues. Does anyone know why this is?
<mbremer> (Sorry the second link doesn't seem to work, maybe try this one https://gist.github.com/bremerm31/797f42e2c20c7b9a4371c1393ff28070 )

<jbjnr> mbremer_: in your second snippet, remember that line 12 is a continuation, so it is executed at some unknown time in the future - putting the vector inside the continuation guarantees that it existss in scope. in snippet #1 the vector is a variable local to the function and is destroyed when the function returns the "big future" on line 26. the vector is destroyed before the continuation is...
<jbjnr> ...actually run.
<mbremer_> @jbjnr So if I understand correctly, your saying that the master thread will have left run and the receive_futures will have descoped in snippet 1?
hkaiser has quit [Quit: bye]
<jbjnr> mbremer_: correct
<mbremer_> Great, thanks!
<pree> mbremer_ : sec
<pree> where the big future is returning ?
aserio has quit [Ping timeout: 246 seconds]
<mbremer_> @pree: It's some partition type component that's getting invoked through a client.
<pree> But I hope in snippet 1 you are passing receive_futures as reference .
<pree> How it is descoped
<pree> as jbjnr said
<mbremer_> Because it's just declared in Run, so once Run returns I imagine receive_futures would descope
<pree> run returns before the continuation ?
<pree> In this case
<pree> If yes means I'm done
<mbremer_> Yes :)
EverYoung has joined #ste||ar
<pree> But I hope it is not always the case
<pree> size of vector matters
<pree> AFAIK
<pree> mbremer_ , jbjnr : thanks

<zbyerly> patg[[w]], yeah that's true. I am submitting a paper to a workshop
<zbyerly> patg[[w]], i can't say which workshop, because it's a secret
<patg[[w]]> zbyerly: good luck
<zbyerly> patg[[w]], for me, just writing a paper will be a big accomplishment
<zbyerly> getting it published would be a huge bonus though
<patg[[w]]> zbyerly: get to work!!!! I wondered what happened since we talked about that one paper
<zbyerly> patg[[w]], i will definitely cite your paper
<patg[[w]]> zbyerly: I'd appreciate that let me know if you want me to look at it when you get close
<patg[[w]]> To done
