<heller> hkaiser: master should turn green again
<heller> and good morning
<hkaiser> great, thanks
<hkaiser> g'morming
<heller> stupid problems
<hkaiser> I need to fix those two tests I disabled, though
<heller> did you create a ticket for those so we don't forget?
<hkaiser> I have not done that
<github> [hpx] hkaiser deleted fixing_2846 at 77fe2e1: https://git.io/v5nvW
<hkaiser> heller: the plan was to first merge Agustin's atomic-lite branhc
<hkaiser> this was the oldest ready-to-go PR
<heller> ok
<heller> we need to adapt some of the new RP stuff which uses boost::atomic
<hkaiser> but thanks for taking care of the others
<hkaiser> heller: I think he did that in his PR already
<heller> also the new stuff?
<hkaiser> yes, that was the idea, at least
<heller> ok
<heller> there are conflicts now
<heller> I might have introduced those
<heller> let me check
<heller> done
<github> [hpx] sithhell pushed 1 new commit to std-atomic-lite: https://git.io/v5nvo
<github> hpx/std-atomic-lite 6fd6dba Thomas Heller: Merge branch 'master' into std-atomic-lite
<heller> ok, next step: fixing CUDA
<heller> in preps for the hackathon
<hkaiser> heller: yah, that's important - we have 3 or 4 tickets for that
<heller> I know
<heller> installing latest CUDA now
<heller> should we care about cuda8 still?
<heller> probably, I guess
<hkaiser> cuda 9 not released yet
<heller> right, only the RC
<heller> and the boost people are messing it up
<hkaiser> well, it's a cuda bug
<heller> yeah
<heller> need to update my CUDA install first
<taeguk> hkaiser: Excuse me, Could I use Rostam cluster continuosly even after GSoC is over?
<taeguk> I continue to need the Rostam for testing and benchmarking parallel algorithms that I will implement more.
bikineev has joined #ste||ar
<hkaiser> taeguk: absolutely
<hkaiser> you're welcome to use it
<taeguk> Thanks a lot :)
<heller> hkaiser: were you guys affected by the hurricane as well?
<hkaiser> heller: rain started overnight only - it just begins for us
<hkaiser> heller: https://goo.gl/eMkhrw
<heller> good luck!
<hkaiser> thanks, we should be fine, even if we get as much rain as predicted
<hkaiser> they say we might see as much as ~50cm rain over the next 2 days
<heller> ok
<heller> sounds like a lot
<hkaiser> heh, it is
<hkaiser> lot'sa flooding ahead
<heller> hkaiser: cuda8 + gcc 5.3 is fine
<heller> at least core + examples compiles ;)
<hkaiser> interesting
<hkaiser> so what are the problems, then?
<heller> people using gcc 4.9 with cuda 8 as it seems
<heller> ah no, stream benchmark fails to compile here as well
<heller> buildbot should be updated to use a newer gcc for CUDA though
<heller> gcc 5.4
<heller> i'll see what I can do after we got green again
<hkaiser> heller: pls send an email to Alireza
<heller> I can do that as well
<hkaiser> k
<hkaiser> good

<hkaiser> heller: we'll probably need to replace the decltype() with c++03-style return type calculations
<heller> yes, that's what I am trying to do right now
<heller> maybe i'll just start at the top of the file ;)
<hkaiser> there was just not sufficient time for Denis to do that
<hkaiser> heller: yah
<hkaiser> shouldn't be too much, actually
<hkaiser> just annoying
<heller> yup
<hkaiser> K-ballo: hey
<heller> I'll figure it out
<hkaiser> is there a std::variant compatible implementation you could suggest using?
<K-ballo> mpark/variant is the best
<K-ballo> and boost licensed too IIRC

<mbremer> hi, I'm running into some weird behaviour on the latest branch of hpx. I used to be able to use the following HPX_REGISTER_CHANNEL_DECLARATION(double), but now I seem to get a lot of compiler errors
<hkaiser_> uhh ohh
<mbremer> Additionally, if I just do using my_type = double; The code seems to compile and run
<hkaiser_> mbremer: our tests compile ;)
<hkaiser_> can you show me the code which fails compiling?
<hkaiser_> is that in your repo for me to try?
<mbremer> It's actually quite a small bit of code. There's a matching register in partition.cpp
<hkaiser_> looks like it
<hkaiser_> what's the compilation error?
<mbremer> I'm happy to play around with it more myself
<hkaiser_> well, so far I have no idea what's wrong
<mbremer> install_Release/include/hpx/lcos/base_lco_with_value\ .hpp:259:20: error: conflicting declaration ‘typedef class hpx::lcos::base_lco_with_value<double\ , double, hpx::traits::detail::component_tag> base_lco_with_value_double’
<mbremer> I can send the full error as well, I just have to pull it off stampede. Let me also double check my build configuration with buildbot
jbjnr_ has joined #ste||ar
<hkaiser_> mbremer: could be a problem in our code, let me have a look
<mbremer> Hmmm. I am building with gcc/7.1.0 and boost/1.64
<zao> Hrm, I wonder if I have 7.1.0 on this box.
<zao> Is this master or a branch?
<mbremer> yup
<mbremer> commit 19030f9e45dabc7e0bb40ff50a8413af857dab36
<mbremer> freshly pulled :)
<hkaiser_> mbremer: I think I know what's wrong
<hkaiser_> zao: tell heller;)
jbjnr_ has quit [Quit: Konversation terminated!]
<hkaiser_> mbremer: ok, I know what to do, your workaround using my_type = double; is the best you can do right now
<hkaiser_> mbremer: may I ask you to create a ticket, I'll take car of this asap
<mbremer> Sure.
<hkaiser_> care* even
<mbremer> Is the problem just the macro isn't right? Or how should I title the ticket?
<jbjnr> Who the heck is Matthew Anderson - and what's he doing above me in the list!

<hkaiser_> thanks
<hkaiser_> heller: you broke K-ballo's aomic-lite branch, btw
<hkaiser_> atomic-lite
<K-ballo> yeah, by merging broken stuff into it no less
<hkaiser_> right
<hkaiser_> merging again should do the trick, though
<K-ballo> broken master stuff, no less
<hkaiser_> nod
<hkaiser_> fixidifix
<hkaiser_> heller's back !
<hkaiser_> K-ballo: does std::variant has some support for recursive variants?
<hkaiser_> or do I have to do that myself?
<K-ballo> yourself, that requires dynamic memory allocation
<hkaiser_> nod
<hkaiser_> unique_ptr<> etc.
<heller> I did fix it, didn't I?
<hkaiser_> yah, just after merging the broken stuff into K-ballo's branch

<hkaiser_> heller: 'should have been fixed' or 'will have to be fixed'?
<heller> It should be fixed
<hkaiser_> doesn't answer my question
<heller> The fix is committed to master
<hkaiser_> 'it should be fixed' has two meanings
<hkaiser_> two possible meanings that is
<heller> Circle-ci is still running.
<heller> Oh no, it's already complete and fixed.
<hkaiser_> heller: pls fix it on K-ballo's branch as well
<heller> Merging the atomic-lite branch is fine
