<Nikunj_> Hey! So I've added a pull request for issue #3124. Here is what I've done
<Nikunj_> 1) Created CMakeLists.txt in examples/hello_world_component. This will not be ran while running cmake for hpx
<Nikunj_> 2) Inside of circle I am creating another folder named test_component and running cmake script for hello_world_component inside it. This will generate the makefiles.
<Nikunj_> 3) I am then running make inside of that folder. This will run the make and build the component inside of test_component.
<Nikunj_> NOTE: I am not testing the hello_world_client so formed since I feel that we are more interested in integrating the build into CI rather than testing it as well.
quaz0r has quit [*.net *.split]
<Nikunj_> In the CMakeLists.txt I did not provide any license headers since I was not sure which ones I had to include.
quaz0r has joined #ste||ar
<Nikunj_> Also, I did not update the respective readme.rst for hello_world_component since I felt that I'd need help in documenting it

<K-ballo> Nikunj_: Boost license, anything and everything must have a boost license disclaimer
CaptainRubik has joined #ste||ar
<Nikunj_> @K-ballo: Ok, I will add a Boost license for CMakeLists.txt and commit the same
<K-ballo> check the other cmakelist files for inspiration
<Nikunj_> I have added Boost licence
<Nikunj_> as for copyright, I found this: Copyright (c) 2011 Bryce Lelbach in readme.rst for hello_world_component. Should the copyright be same for CMakeLists.txt as well?
<hkaiser> Nikunj_: add yourself in the copyright
<hkaiser> that's the whole point of it ;)
<Nikunj_> Ok :)
<Nikunj_> License headers have been added :)
<hkaiser> Nikunj_: however, the cmake file you propose does not use the script to build the example, it builds it directly instead
<Nikunj_> @hkaiser: I did'nt get you. Can you please elaborate.
<hkaiser> Nikunj_: the cmake script does not generate a build system that invokes the build.sh script
<Nikunj_> @hkaiser: Oh yes, I have directly integrated it to the build.
<hkaiser> Nikunj_: didn't we discuss the other day that building the example using the build.sh script was the whole point ?
<Nikunj_> @hkaiser: The other day, while talking to @heller and he asked me to integrate according to the docs provided at https://stellar-group.github.io/hpx/docs/html/hpx/manual/build_system/using_hpx.html
CaptainRubik has quit [Ping timeout: 260 seconds]
<Nikunj_> That's why I switched from creating a build.sh to directly integrating it.
<hkaiser> Nikunj_: ok
<hkaiser> heller_: what's your rationale to switch away from the script?
<hkaiser> Nikunj_: if this is really supposed to directly invoke cmake (instead of the script) then there is no need to restrict things to linux
<Nikunj_> @hkaiser: The broken example showed itself broken with both pkg-config and cmake. That's why I felt it to integrate directly.
<hkaiser> understand
<K-ballo> I don't, was the script itself wrong?
<hkaiser> K-ballo: I think heller_ wanted to make sure that at least the code compiles (as this was the initial issue)
<Nikunj_> @hkaiser: As for linux only, I can edit the script to make it work for every operating system.
<hkaiser> but I hoped for testing the whole thing, frankly
<Nikunj_> @hkaiser: What should I do now?
<hkaiser> Nikunj_: let's wait for heller_ to respond, I'd like to hear his side of things
<Nikunj_> @hkaiser: Ok
mcopik has quit [Ping timeout: 256 seconds]
<Nikunj_> @hkaiser: Should I work on creating build.sh as a side-work in case we decide to switch to creating build.sh instead?
<hkaiser> Nikunj_: sure, if you would like to do that?
<Nikunj_> @hkaiser: Ok, in that case I'll start working on that as well. However, one thing to note, I have mid-semester exams from 19th feb so I won't be able to actively participate from 19-21st feb.
<Nikunj_> @hkaiser: I will, however, try my best to incorporate the pull request before 19th.

<galabc> I have a question about the HPX smart executors from the article https://arxiv.org/pdf/1711.01519.pdf
<galabc> I know that the smart executors use logistic regressions to find the best parralelization parameters
<galabc> But do the weights that are used in the regression depend on the type of task?
<galabc> For example if I want to optimize matrix mutiplication or Matrix inversion
<galabc> will the smart executors use the same weights for both tasks?
<hkaiser> galabc: the parameters are extracted by the compiler
<galabc> ok but the regressions help find the optimal chuck size and prefetching distance if I understood correctly
<galabc> And I wonder if the weights and biases used in the regression will vary will the type of task
<galabc> with the type of task**
<hkaiser> we have not adapted the weights to the task types yet
<galabc> Ok I see
<galabc> So the regression works for many type of tasks
<galabc> That is very interesting
<hkaiser> yah, that's a cool project
<galabc> Do you think this would be a good direction for a GSoC project?
<galabc> maybe its too advanced
<hkaiser> direction - in what sense?
<galabc> well if it would be possible in the time allowed
<galabc> Or if it would be better to work on others models
<galabc> Maybe it would be interesting to develop another model (like neural networks or Nearest-Neigbour) as a summer project
<hkaiser> galabc: even the existing topic needs more work
<galabc> I see
