<srinivasyadav227> Would it be useful to provide an example for Pascal Triangle Matrix filling?
<srinivasyadav227> a very beginner friendly example for hpx::futures
<srinivasyadav227> I could provide 3 variations (plain serial, openmp version, hpx futures)

<diehlpk_work> srinivasyadav227, Sure, that could be interesting
<srinivasyadav227> diehlpk_work: thanks, cool! 🙂
<diehlpk_work> You could put them into a repo on Github and share your code with us
<srinivasyadav227> diehlpk_work: okay, not a PR?
<hkaiser> let's keep it separate for now
<srinivasyadav227> okay
<diehlpk_work> We can provide you feedback using issues
<srinivasyadav227> sure 😀

<K-ballo> anyone has an example algorithm to compute variance in parallel?
<gnikunj[m]> a naive implementation could be done with 2 reductions. First reduction to compute the average and second to compute (x - xavg)^2.
<gnikunj[m]> I can write that for you if you want.
<K-ballo> no, I need single pass.. I have an implementation (based on wikipedia) but the numbers I'm getting are waaaaaay off
<rori> hkaiser: the hip github action now works, but my exclude regex for the testing does not work (see [error](https://github.com/STEllAR-GROUP/hpx/pull/5217/checks?check_run_id=2032122327), see [exclude_regex](https://github.com/aurianer/hpx/blob/add_hip_github_action/.github/workflows/linux_hip.yml#L43-L44)), any ideas what I might do wrong?
<hkaiser> rori: let me have a look (have to run in a sec, but will look later, though)
<rori> yes it's not urgent, thansk
<K-ballo> based on wikipedia :P
<hkaiser> yes
<K-ballo> actually that one is fine
<K-ballo> I'm having trouble with the one merging chunks
<hkaiser> nod, parallel is more tricky
<K-ballo> my second moments were all wrong :/

<bita> hkaiser, I found that Zoom setting: it's in their webpage, https://lsu.zoom.us/ -> setting -> screen sharing to all participant
<hkaiser> bita: ahh, thanks - I'll try that
<hkaiser> found it
