<adityaRakhecha_> simbergm, I followed this tutorial https://stellar-group.github.io/hpx/docs/sphinx/latest/html/quickstart.html, but in this directory there was no fibonacci_local(hpx.examples.quickStart)
<adityaRakhecha_> I just checked our hpx repo and it has the fibonacci_local script.
<adityaRakhecha_> Should I rebuild again by cloning the repo from there or I am wrong somewhere ?
<simbergm> adityaRakhecha_: yes please, just try from scratch with the master branch and a fresh build directory
<adityaRakhecha_> okay.

<hello> zao: lol
<zao> beep boop
<hello> I found the reason about problem yesterday.
<zao> Oh?
<hello> when I use 128 core, then the program run rightly.
<hello> so how many core do you use yesterday?
<K-ballo> proposed std::function_ref looks dangerous:
<K-ballo> void fun() {}
<K-ballo> function_ref<void()> r1 = fun; // refers to fun
<K-ballo> function_ref<void()> r2 = &fun; // refers to pointer temporary (dangling)
<K-ballo> I think I'm going to change that for our implementation

<adityaRakhecha> simbergm, same results. :(
<zao> hello: 64 tasks, like you.
<zao> 16 or 32 per node.
<zao> K-ballo: Oh boy.
<simbergm> adityaRakhecha: uhh, that's strange
<simbergm> you have HPX_WITH_EXAMPLES=ON?
<simbergm> (you can check with ccmake)
<adityaRakhecha> simbergm, I think there is something wrong I did during building hpx, I followed this thread https://github.com/STEllAR-GROUP/hpx/issues/2524 and used `cmake -DHPX_WITH_MALLOC=system ..`
<adityaRakhecha> How to know and check that?
<simbergm> is it successful?
<simbergm> you can do ccmake .
<simbergm> `ccmake .` that is
<simbergm> in the build directory
<adityaRakhecha> Yes, it was successful. The hello world program was running smooth.
<simbergm> and `git rev-parse HEAD` gives you what?
<adityaRakhecha> Yes I have HPX_WITH_EXAMPLES=ON
<adityaRakhecha> `git rev-parse HEAD` gives `3a95a3cd5f00d7b957b06b3d8047387a7d775bd4`
<simbergm> adityaRakhecha: you're one release behind, but it's not your fault
<simbergm> do `git checkout 1.2.0` and you should be good to go
<adityaRakhecha> Done. Same message(error). I did earlier too as the tutorial says.
<simbergm> adityaRakhecha: and `git checkout master`? please wipe the build directory in between, or at least do `cmake my_build_dir`

<simbergm> K-ballo: @chinz07:matrix.org was, I think
<K-ballo> chinz07[m]: are you working on modernizing our cmake scripts?
<chinz07[m]> K-ballo: Yes, slowly but steadily.
<K-ballo> chinz07[m]: I have a request, see if we can specify `CONFIGURE_DEPENDS` for globbing when using a recent enough cmake version
<K-ballo> I'm switching between branches with different sources, and each time I do I forget to re-configure before build,
<chinz07[m]> K-ballo: I'll take a look at it after finishing my current PR, which should be ready within the next few days. Since `CONFIGURE_DEPENDS` is not guaranteed to work (reliably) for all generators, we should only provide it as an optional feature IHMO.
<K-ballo> we already suck and do globbing, so as long as it is doable adding the flag only makes it less worse
<chinz07[m]> Fair enough.
<heller_> hkaiser: do we talk today?
<hkaiser> heller_: if you want to, sure
<heller_> hkaiser: sure
<heller_> hkaiser: ready whenever you are
<hkaiser> sec
<diehlpk_work> We need a Wikipedia article about HPX. so we could reference HPX on other articles :)

bibek has joined #ste||ar
hkaiser has joined #ste||ar
<heller_> diehlpk_work: we already have one :P
<heller_> we might want to update it...
<diehlpk_work> Yes, we should do that
<diehlpk_work> Add octotiger and some new applications
<diehlpk_work> Add some references
<heller_> sure
<diehlpk_work> I will update the version
<heller_> I think self promotion is frowned upon though
<heller_> so be careful
<diehlpk_work> I think we could at least update the version and provide some basic references to HPX
<diehlpk_work> And add recent applications or?
<heller_> try it
<heller_> I never did a wikipedia entry
<diehlpk_work> I just updated some
<diehlpk_work> And added some references and links to software
<diehlpk_work> I think we should not advertise too much, but keep it updated
<diehlpk_work> hkaiser, Did you or wash[m] started this wiki entry https://en.wikipedia.org/wiki/High_Performance_Parallex ?
<diehlpk_work> At least I updated the latest release to 1.2
<hkaiser> diehlpk_work: I don't remember who created that, isn't there a edit history ?
<zao> Neither, I'd reckon, considering that it's strongly frowned upon.
<diehlpk_work> hkaiser, 19:25, 30 July 2012‎ Ared38 (talk
<diehlpk_work> This person did some changes in 2012
<diehlpk_work> And only 2018 one person and bots did changes
<diehlpk_work> I updated the version of HPX and release date and remove unstable from our github repo
<diehlpk_work> simbergm, Can we add update the HPX release in the wiki entry to our release notes?
<hkaiser> diehlpk_work: good thinking
<diehlpk_work> We had 0.99 there
<heller_> diehlpk_work: this is the 7th year of gsoc, right?
<diehlpk_work> hkaiser, Would you mind if I update the wiki entry little bit?
<heller_> 6th
<heller_> diehlpk_work: btw, be prepared that we aren't accepted this year ... I really wonder when we'll be hitting the decline rotation they keep doing for the last years
<diehlpk_work> heller_, I am be prepared, but we still should try to apply
<heller_> sure we should
<heller_> just saying ... 6 times in a row ... that would be massive
<diehlpk_work> really? I think some orgs have more or?
<heller_> in a row?
<heller_> well, maybe umbrella ones
<hkaiser> diehlpk_work: not at all
<heller_> simbergm: cancelable action still fails :(
<diehlpk_work> heller_, I do not know how we can get this number, but I meet people at the mentor summit attending 10 year or so
<heller_> alright!
<heller_> no idea how to get this number either...
<heller_> maybe ask the gsoc admins about stats ;)
<diehlpk_work> We will see soon, but I agree 6th years in a row would be cool
<diehlpk_work> At least students started to look into our projects
<heller_> he
<heller_> right
<heller_> diehlpk_work: "Mentors who have participated in GSoC for 10 or more years: 46"
<heller_> diehlpk_work: "Mentors who have been a part of GSoC for 5 years or more: 272"
<diehlpk_work> Ok, we might be one of these 271
<diehlpk_work> or even become one of these 46
<heller_> so me and hartmut are in the top 1%
<diehlpk_work> Congrats
<heller_> lol
<heller_> doesn't say in a row though!
<diehlpk_work> I think we have good chances to be selected again. Our success rate was not too bad
<heller_> the success rate is irrelevant
<diehlpk_work> Ok, so we will see beginning of Feb if we are in or not
<heller_> yes ;)
