<bering[m]> Are there user-defined literals for std::size_t in HPX?
<Deepak1411[m]> Hey, there I was trying to build hpx on my windows but, when you go for installing boost x64 it throws access denied . Can someone please help me out. I have given the images regarding issue
<srinivasyadav227> idk if this helps, but can you try with cmd as admin?
<Deepak1411[m]> I tried it in cmd only
<srinivasyadav227> Deepak1411: no i mean run cmd as "Run as administrator"
<Deepak1411[m]> I'll try and let you know, thanks
<Deepak1411[m]> srinivasyadav227: hey still showing that
<srinivasyadav227> Deepak1411: okay, firstly did you install vcpkg application ? this might help https://www.programmersought.com/article/1669209319?
<Deepak1411[m]> srinivasyadav227: yes installed it
<srinivasyadav227> Deepak1411: ok, sorry, i am not sure what might be the actual program, hkasier might be right person to help you with this :), anyways assuming yours is 64bit windows machine and have latest Visual studio, you may try installing vcpkg cleanly again from the above link , and try again, as this was working for me.
<Deepak1411[m]> ok fine, I'll try once again and yes using a 64bit machine
<Deepak1411[m]> thanks for responding 🙂
<srinivasyadav227> :)

<zao> Deepak1411[m]: You may be running into antivirus or other protection like SmartScreen preventing access to things. Also make sure that the Windows installation is 64-bit (easiest seen in the Win+Break About screen).

<gonidelis[m]> hkaiser: do you have 20 minutes within the day?
<hkaiser> gonidelis[m]: I could meet at 10am CDT
<gonidelis[m]> cool
<gonidelis[m]> thanks!
<Deepak1411[m]> zao: Yes finally it is done, it was the antivirus protection stoping it , 🙂
<zao> Sweet.

<diehlpk_work> ms[m], gdaiss[m] Could you please add some content to 7.5. Kokkos vs CUDA and add the HIPS results there?

<hkaiser> gonidelis[m]: I'm available now
<gonidelis[m]> hkaiser: i am having lunch, would you be available in 15?
<diehlpk_work> ms[m], Please add your affiliation to the paper
<hkaiser> gonidelis[m]: sure, np
<gnikunj[m]> hkaiser: sent you the email. Let me know if you want me to add/delete anything.
<gonidelis[m]> hkaiser: link

<bering[m]> There is a ~300% performance regression for the callback mode of the CUDA executor, using its performance test.
<bering[m]> The regression is introduced by commit
<bering[m]> b5a7913aad (Fix check in unregister_thread and add register bool, 2020-10-14)

<hkaiser> bering[m]: could you please create a ticket for this?
<bering[m]> Alright.
<rori> Thanks for noticing, this is on me, when I did the hip support, will have a closer look!
<ms[m]> bering: that's specifically that commit, correct? the immediately preceding commit works perfectly fine (and performs better) for you?
<bering[m]> Yes.
<ms[m]> also thanks for finding the commit!
<ms[m]> all right, we'll see what we can do
<ms[m]> how critical is the callback version for you? do events work well for you?
<bering[m]> It is not critical at all. So, no worries. I use it only for comparison and can simply use the results from the good version.
<ms[m]> diehlpk_work: will do
<bering[m]> I was not quite on current master while testing, though. So, I will double-check on master and create a ticket then. Probably it went away since then.
<bering[m]> The event mode does not seem to be affected.
<ms[m]> bering: most likely it won't have been fixed on master, unless there's some spooky action at a distance... the changes from that commit are still on latest master
<gonidelis[m]> hkaiser: without optimizations all threads are active 99% for a cilk app. with the optimizations all threads are active 50%...

<hkaiser> gonidelis[m]: ok, so at least mutliple cores are activated ;-)
<gonidelis[m]> Could it be that clang++ calculates the loop on compile time ??
<hkaiser> look at the assembly, that will tell you
<hkaiser> gonidelis[m]: or do a relwithdebinfo build (i.e. with optimization and debug symbols) and use a debugger
<Deepak1411[m]> hello all , I was stuck at the last step of building the source in Visual studio. After building it shows as follow
<Deepak1411[m]> I could not get this, just see for reference **Compiler Error C2182** https://docs.microsoft.com/en-us/cpp/error-messages/compiler-errors-1/compiler-error-c2182?f1url=%3FappId%3DDev16IDEF1%26l%3DEN-US%26k%3Dk(C2182)%26rd%3Dtrue&view=msvc-160
<zao> Deepak1411[m]: There's way more information in the Output pane.
<zao> Output -> Build, that is.
<hkaiser> Deepak1411[m]: what version of VC do you use?
<hkaiser> VStudio, that is
<zao> hkaiser: For reference, I just did an x64 RelWithDebInfo build of hpx master examples+tools with VS 16.10.0, Boost 1.76.0, hwloc 2.4.1; deps from upstream binaries.
<zao> (successfully, I might add)
<gonidelis[m]> zao: now try doing one on Cilk ;p
<zao> Blissfully unaware what Cilk is :D
<gonidelis[m]> the best parallel runtime on the world
<Deepak1411[m]> <hkaiser "Deepak1411: what version of VC d"> VS 2019
<gnikunj[m]> hkaiser: am I on the wrong zoom, or is there no meeting today?
<zao> Deepak1411[m]: What particular minor version, there's a lot of them :)
<zao> (you can see it in the installer or the About window)
<Deepak1411[m]> zao: Microsoft Visual Studio Community 2019
<Deepak1411[m]> Version 16.9.5
<gonidelis[m]> * the best parallel runtime in the world
<zao> I'm on 16.10.0, not sure how far back we are supposed to support.
<zao> hkaiser: ^
<hkaiser> that's fairly recent
<hkaiser> Deepak1411[m]: we'll need more information to be able to help
<zao> Deepak1411[m]: I recommend taking the text from the Output pane's "Build Order" listing to get the actual warnings, errors and notes; and put it in a GitHub Gist and link that here.
<zao> The errors listing is a bit too short-worded and skips most of the context needed to understand an error.
