<ms[m]> srinivasyadav227: any chance you've had time to look at the datapar build failures on circleci: https://app.circleci.com/pipelines/github/STEllAR-GROUP/hpx/8871/workflows/9f63859c-78aa-42ed-bc33-836a9549aa89/jobs/267395?
<srinivasyadav227> ms: yeah, still trying to find the issue :) just got back to working on adapting simd algorithms and fixing this last week. I will try to fix it and push ASAP.
<ms[m]> srinivasyadav227: ok, no worries
<ms[m]> thanks for looking into it!
<dkaratza[m]> ms: luckily you saw the missing file..phew
<dkaratza[m]> i fixed it, so i think now its fine if you'd like to check it
<ms[m]> thanks dkaratza! possibly one more thing missing, commented on the PR
<dkaratza[m]> <ms[m]> "thanks dkaratza! possibly one..." <- which one are you talking about? how to install HPX with various package managers?
<dkaratza[m]> i think this is in the quickstart
<ms[m]> dkaratza: no, linking from that section to the build instructions https://github.com/STEllAR-GROUP/hpx/pull/5534#discussion_r712042094
<dkaratza[m]> <ms[m]> "dkaratza: no, linking from..." <- i messed up with the versions, sorry for the inconvenience
<dkaratza[m]> i updated it, hope it's fine now :)
<ms[m]> after that I think it's good
<dkaratza[m]> <ms[m]> "after that I think it's good" <- done!

<jedi18[m]> hkaiser: I had a doubt regarding ranges
<jedi18[m]> I was under the impression that views make use of the already existing algorithms, but they actually have seperate implementations.
<jedi18[m]> So this means we can't directly use our parallel algorithms with views and so can't pipe/make use of loop fusion right?
<jedi18[m]> So will we have to implement our own parallel view algorithm implementations if we wish to make it work with views?
<hkaiser> jedi18[m]: yes, they hav etheir own (sequential) implementations
<hkaiser> but that's fine
<hkaiser> the point is to be able to do something like: auto v = generate(rand) | transform(...); hpx::for_each(par, v);
<jedi18[m]> Oh ok understood, so we never intended to have view algorithms that were parallel?
<hkaiser> no
<jedi18[m]> Ok thanks
<hkaiser> jedi18[m]: that's probably not possible anyways
<jedi18[m]> Yeah

<hkaiser> gonidelis[m]: you did ask for ranges in c++23 yesterday - this might shed some light: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2214r1.html
<hkaiser> gnikunj[m]: will you be available tomorrow for the gsoc/snl meetings?
<gnikunj[m]> hkaiser I think I can. Not much progress though :/
<gnikunj[m]> I'll work on it today
<hkaiser> gnikunj[m]: it's the last meeting, so let's wrap things up
diehlpk has quit [Quit: Leaving.]
<hkaiser> right down our alley
