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

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?
<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 :)

<pree>
But I hope it is not always the case
<pree>
size of vector matters
<pree>
AFAIK
<pree>

zbyerly: well I know HPX has a 1/2 day tutorial (not sure I'll be able to go to that)
Rodario has quit [Ping timeout: 240 seconds]
<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
