Re: [hpx-users] Prospective Student for GSoC 2020 for project in Stellar under your guidance

[Patrick Diehl]

Hi Ronni,

one first step we recommend to all of the GSoC applications is to build
HPX and run some of the examples.

Please join our irc channel #ste||ar on the freenode server and start to
talk with your mentors.

Best,

Patrick

Re: [hpx-users] Enquiry regarding GSOC 2020

[Patrick Diehl]

Hi Indranil,

have you seen the project list on GitHub?

You could see if one of these projects are interesting to you.

Also building HPX and running some examples could be a good idea.

Feel free to join the irc channel ste||ar on the freenode server to start a
discussion.

Organizations-- If you would like to apply for the 2020 program please
start thinking about the projects you would like students to work on and
also reach out to your community members to ask if they would like to be
mentors for the program. Having a thorough and well thought out list of
Project Ideas is the most important part of your application.

Encourage other open source orgs to apply-- Please also consider
encouraging other open source projects to apply and be a first time GSoC
org - we’re hoping to accept more orgs in 2020 than ever before with a
good number of them being first time orgs. When orgs apply they can put
your org down as a reference.

Please note that Org applications will open on January 14th. 

This year we have shortened the community bonding period to 3 weeks per
feedback in the 2019 surveys from students and mentors.

Dear Madam or Sir / Sehr geehrte Damen und Herren,

Strong scaling is still a real problem in HPC.

Therefore, we provide the second time this course on HPX, which
implements a lightweight threading model that allows both concurrent,
asynchronous, parallel and distributed programming constructs.

Please, can you pass this HPX course announcement also to interested
colleagues.  / Es waere schoen, wenn Sie diese Ankuendigung

https://nam04.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.hlrs.de%2Ftraining%2F2019%2FHPXdata=02%7C01%7Cpatrickdiehl%40lsu.edu%7C9499bfcc76c64728275c08d6d9eb5998%7C2d4dad3f50ae47d983a09ae2b1f466f8%7C0%7C0%7C636936002185280144sdata=JXt1A%2BTg2StZoUOvgj%2BTuE07bEK4yqLQfO73WcgjRcM%3Dreserved=0

The aim of this course is to introduce participants to the HPX library
and demonstrate how it can be used to write task based programs.
The HPX library implements a lightweight threading model that allows
both concurrent, asynchronous, parallel and distributed programming
constructs to coexist within the same application with a consistent API
based on C++ standards and using futures to synchronize between tasks.

The course is aimed at participants with a good understanding of C++.
The material covered will include
 - an introduction to the HPX programming model,
 - asynchronous programming concepts, execution policies and executors,
 - parallel algorithms using tasks (including the parallel STL),
 - writing distributed applications with HPX,
 - profiling and debugging, and
 - a final section introducing heterogeneous programming
   using targets for GPU devices.

Objective: The attendee will gain an understanding of the
   HPX library and task based programming in general.

Lectures will be given by
 - Thomas Heller, FAU Erlangen-Nuremberg,
 - John Biddiscombe, CSCS,
 - Mikael Simberg, CSCS.

Registration deadline: June 9, 2019.

The course language is English.
All slides and handouts are also in English.

Kind regards
Rolf Rabenseifner, Lucienne Dettki and Jose Gracia (HLRS)

Re: [hpx-users] [GSoC 19] Providing a pip package for Phylanx

[Patrick Diehl]

Hi,

I do not think that you will need much knowledge of C++ and CMake. I
think you will need some knowledge how the pip packages work and good
knowledge about compilation of hpx and phylanx.

I would recommend to start to read the pic docs and generate a package
for some hello world example.

Best,

Patrick

Hi,

a good entry point is to compile HPX and run the examples. In addition,
you should look into the quickstart examples to learn more about HPX.

Joining our irc channel is very helpful to get into contact with the HPX

[hpx-users] PGP key for signing hpx releases

[Patrick Diehl]

Hi,

since we intent to release HPX 1.2 soon, we generated a pgp key [0] to
sign our releases from this release on.

Please be so kind and sign the release key with your key to improve its
credibility.

Thanks,

Patrick

Hi,

you could start to compile HPX and play around with the examples. In
addition, you could look into our issues and pick one easy one and start to
work on solving this issue.

Re: [hpx-users] [STE||AR Gsoc] GSoC 2nd evaluation summary

[Patrick Diehl]

I have to add that we told Jakub to first have a proof of concept of the
integration of HPX. And he should not focus too much on optimization in the
first phase. I assume we have to play around with execution policy and
chunk size as for BLAZE to get better performance. First, HPX was much
slower as openmp with default settings and after adjusting it was
comparable to openmp.

[hpx-users] Fwd: [SIAM-CSE] Call for Submissions to SC18 Doctoral Showcase

[Patrick Diehl]

Hi,

could be interesting for our PhD candidates.

Best,

Patrick

 Forwarded Message

Date:   Mon, 11 Jun 2018 19:20:47 +
From:   Sanjukta Bhowmick 
To: siam-...@siam.org 



Dear Colleagues,


We invite submissions for the Doctoral Showcase program for
Supercomputing 2018. Unlike papers and poster presentations, a Doctoral
Showcase poster (called a /thesis canvas/) highlights the entire
contents of a dissertation, including previously published results, to
allow for a broad perspective of the work. The Doctoral Showcase
provides a unique opportunity for students nearing completion of their
PhD to present a summary of their dissertation research in the form of
talks and posters, and network with prospective employers.

Please see
https://sc18.supercomputing.org/submit/showcases-submissions/#section1

for details on submissions.

*Submissions Close*
July 31, 2018

[hpx-users] Fwd: [STE||AR Gsoc] Evgeny Dedov Newtonian Physics Sandbox report

Subject: [STE||AR Gsoc] Evgeny Dedov Newtonian Physics Sandbox report
To: 


Hello STE||AR GSoC community

Most of the reporting can be seen in my correspondence with Andreas which
was also held in this mailing list, so here I'll write in a nutshell.

In proposed milestones by 10th of June I written:

   - Bodies classes. Spheres case.
   - Initializers
   - Writer.
   - Collision detection.
   - collision resolving.


Completed:

   - Physical body interface class, implementation for body composed form
   spheres.
   - Collision detection, including bounding objects and tree of bounding
   objects and bounding sphere implementation of them
   - Collision resolving
   - Initializer
   - Writer


left unfinished / troubles:
when we create body composed from spheres it'd be good to calculate and
store tree bounding spheres or at least one bounding sphere. Now it works
only if body is a sphere.
Simulation must have the only type of physical body.
Some problems with SerialSimulator

All welcome to take a look at source:
https://github.com/V3RGANz/Newtonian-Physics-Sandbox
I also had a blog there, but had no time to post in it.

P.S. As I noted in the proposal, I had tests and exams at the university at
this stage, so I worked inconstantly, but in the following month I will
have more free time.

Sincerely,
Evgeny Dedov

[hpx-users] Fwd: [STE||AR GSoC-students] HPX Backend for OpenCV - First Phase Report

[Patrick Diehl]

-- Forwarded message -
From: Jakub Golinowski 
Date: Sun, Jun 10, 2018, 10:47 AM
Subject: [STE||AR GSoC-students] HPX Backend for OpenCV - First Phase Report
To: 


Dear Ste||ar GSoC community,

I would like to submit short report of my progress during the first phase
of GSoC.

The main achievement of this moth is a working HPX backend for OpenCV.

During the development it was discovered that the parallel_for_ loop which
is the base for all parallel execution of OpenCV's jobs is not only exposed
to the user but is also used indirectly by some OpenCV filters. In the
latter case there is a workload based partitioning introduced based on the
domain-specific knowledge of the particular computer vision operation.
Because of that the simple backend version with partitioning done fully by
HPX was extended to the version supporting partitioning propsed by OpenCV.

What is more there is a question of when to start the HPX runtime. For now
there are to versions developed:

   - simple backend that assumes that HPX runtime is on,
   - start-stop backend that is starting and stopping the runtime for each
   parallel_for call.

After the benchmarking experiments it is decided that the final version of
the backend will be a "smart start-stop". It will perform all the necessary
checks to determine if the backend is running and then based on that either
start the runtime (and of course stop it later) or directly proceed to hpx
calls.

The backend itself is developed in two branches of my fork of OpenCV
repository (hpx_backend
 and
hpx_backend_eval
). The
eval branch is more up-to-date and has additional cmake options which
enable to choose between versions of the backend:

   - with or without support for OpenCV partitioning,
   - simple mode (assume HPX runs) or start-stop mode.

Small example applications using HPX, application used for benchmarking
(opencv_mandelbrot) and necessary bash and python scripts can be found in
this repository: https://github.com/Jakub-Golinowski/opencv_hpx_backend

In the next 2 months the backend will be developed in its final version
(most probably smart start-stop) and the efforts to merge it to OpenCV
repository will be started. Apart from that, the example application
combining OpenCV with freshly developed HPX backend, access to webcam and
QT GUI will be developed.

Best regards,

Jakub Golinowski

I would recommend you to look into the code and find the places where
GIDs are used ad start to ask questions.

Please keep in midn that the deadline for submitting the proposal is soon.

Hi Kunal,

welcome to the community. A good start would be to compile hpx and run
the examples and understand some of them. For your project, it would be
helpful to start to use the performance counters in one of the examples.
The stencil example could be a good start to play around with the
performance counters.

You have to run the code with x_1,x_2,...,x_n and measure the y values
for those input values.

Re: [hpx-users] Machine learning applied to HPX smart executors

[Patrick Diehl]

Hi Gabriel,

I am not sure if it is possible with one regression, but maybe with a
more sophisticated model. But it is up to you what you want to propose
in your proposal. I think one task of this project would be to find out
which model is suitable to do this.

You can either propose a different approach or a combination of
regression models.

Patrick

Hi Ray Kim,

No, the project's solution should be independent on any library. One
requirement would be, that it works independent on the compiler. HPX
itself provide performance counters [0]. These ones could be used for
acquisition of data. Or just data you could measure during run time.

>> And I guess part of a machine learning framework -such as xgboost,

>> 
>>  will also need to be included in the distribution.

No, I think this would be not needed. It really depends on your
approach. If you collect data and try to generate a model and use the
trained model without any machine learning during run time, I would
recommend to use scikit-learn [1]. It is easy to use and you can easily
play around with different models.

For the case when you want to use machine learning during run time, I
would recommend to use scikit-learn to find a suitable model. Once, you
found this model, you should have a look into the model and implement
these algorithms by yourself. I think that we do not need a very
sophisticated model and it would be easy to implement this model.

In addition, I recommend to read the previous mentioned paper to get
some more details.

Best,

Patrick

Re: [hpx-users] GSoC 2018, on "applying machine learning technques ..." project

[Patrick Diehl]

Hi Ray,

welcome to the community. A good starting point for this project would
be to read this publication [0]:

Zahra Khatami, Lukas Troska, Hartmut Kaiser, J. Ramanujan and Adrian
Serio, “HPX Smart Executors”, In Proceedings of ESPM2’17: Third
International Workshop on Extreme Scale Programming Models and
Middleware (ESPM2’17), 2017. doi: 10.1145/3152041.3152084,

>> Then is the goal to analyze data? or also implement the algorithms?

The goal is to provide a new execution policy [1], which utilizes
machine learning techniques to optimize the computational time.

So the first step would be to analyze the data.

In my opinion there are two different ways, one can integrate machine
learning.

1) You could collect the data and train a model to obtain parameters for
your function f(x,y,z) -> chunk size. In this case you could use any
existing machine learning library to get these parameters for your function.

Here, you will implement this function in the execution policy to
estimate e.g. the "best" chunk size for given x,y,z.

2) You could train your model at run time to obtain e.g. the "best"
chunk size. In this case you have to implement your chosen machine
learning algorithm for the integration in hpx.

Best,

Patrick

Hi Nikunj,

We can not assign this issues to you right now, you have to apply for
GSoC and after you got selected, we can assign you this issue.

Please find attached here some hints for writing a successful proposal [0].

Re: [hpx-users] Open source contribution

[Patrick Diehl]

Hi,

you could have a look at our GSoC proposals [0] or at our issues [1] and
see if you are interested in one of this projects.

>> I m willing to contribute as much as i can after my college hours.

Google Summer of Code is a full-time commitment and you can not do this
next after your college hours.

This statement is taken from the GSoC guide lines for students.

[hpx-users] Combine HPX and openmp-based library

[Patrick Diehl]

Hi,

as you may know I am working on an computational mechanics code based on
HPX. Now I finished the basic implementation in C++ and now started to
use HPX for the parallelism. One big issue is that application is based
on linear algebra including solving a large equation system which of
course is the bottle net of the application.

Is there any way to use a library which uses openmp inside of HPX? I am
know using libeigen for the linear algebra part and what I like to use
its parallel solver inside a future.

What is the best way to combine HPX with openmp?

I think finding a solution for the integration of parallel linear
algebra libraries would be an huge improvement for HPX in application in
computational engineering.


Best,

Patrick

Hi Akshay,

you could start to read the documentation [0] and compile HPX on your
machine [1]. Also joining our irc channel #ste||ar at freenode would be
a great opportunity to get in contact with the community.

Re: [hpx-users] Your interest in HPX

[Patrick Diehl]

Hi,

we have a bachelor thesis for the validation of HPX for a two
dimensional fluid dynamics solver. The student is evaluating how HPX is
feasible for this numerical task. A large part of the computational
effort is the solving of a linear equation system and matric vector
operations.

Best,

Patrick
