Re: [hpx-users] [GSoC 2017] Proposal for re-implementing hpx::util::unwrapped

[#SESHADRI MADHAVAN#]

Hi Zahra,

I have proposed the idea for working on HPXCL with Patrick, hence I shall not 
be proposing this as my GSoC project, but I would love to jump into "Applying 
machine learning techniques on HPX algorithms". The project seems interesting 
and I have had some background implementing Machine Learning algorithms on 
Hadoop, predominantly in Java. But I have been through the process of designing 
and optimizing algorithms for execution in parallel which I believe will be 
useful for this. Let me know how I can get started.

Best Regards,
Madhavan

Hi Denis,

I am so glad that you are interested in HPX GSOC.
I have looked at your github and your projects seems so interesting for me. 
Feel free to write your proposal and submit it before April 3rd. I would be 
happy to be your mentor, as I have found your background match with my current 
projects as well. If you go through

https://github.com/STEllAR-GROUP/hpx/wiki/GSoC-2017-Project-Ideas#re-implement-hpxutilunwrapped

You will find a project "Applying machine learning techniques on HPX 
algorithms", which I think it could be a good fit for you too. Our team has 
been working on it since 2-3 months ago and so far we have got interesting 
results, which are going to be prepared for a conference paper. In this project 
we are using LLVM and Clang LibTooling to implement a machine learning 
techniques on an HPX parallel algorithm, and we have applied and tested them on 
an hpx loop.
So as another option, you could look at this GSOC project idea and write a 
brief proposal about how you can implement it.

Hi Denis,

the ides sounds good, for GSoC, you should submit your proposal at their
official website. You can use this template [0] and our guidelines [1]

We are looking forward to review your proposal.
