Hello Mentors and Org Admins,

We are pleased to announceGoogle Summer of Code 2020 ,
the 16th consecutive year of the program.

The programannouncement
,timeline
,marketing
materials
(slide
deck, flyers),FAQs ,
andshort videos
with tips for
mentors and students are all available. You'll also notice the 2019
program has now beenarchived
.

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.

We are looking forward to another exciting year of GSoC!

For any questions about the programs please email us at

Subject: [hpx-users] Request for Experience

 

Dear Colleagues,

 

my name is Martin Ohlerich. I'm working at the Leibniz Super-Computing
Center near Munich (LRZ), and test currently the capabilities of HPX. On our
Linux cluster with infinitband network, the tests were so far successful. On
SuperMUC-NG, we've an Intel OPA network, which seems to have some
peculiarities (that we also observed when trying to employ GPI (GASPI)). Is
there any experience with such a network type for HPX in the community?

I welcome any hint on where to find about the startup mechanism, and
debugging possibilities. I tried so far the easy approach to install HPX via
Spack. On SNG that might be not the correct way to go.

 

Many thanks in advance! Also in the name of our users!

Best regards,

Martin Ohlerich

In order to collect and write the OTF2 trace, please set the environment 
variable APEX_OTF2=1.  For example:

export APEX_OTF2=1
./apex_fibonacci

or 

APEX_OTF2=1 ./apex_fibonacci

Thanks -
Kevin

Re: [hpx-users] HPX 1.4.0 release candidate 2

[Simberg Mikael]

Hi Kor,


You'll also want to export APEX_OTF2=1 to actually generate the OTF2 files. It 
should end up in OTF2_archive/APEX.otf2 in the directory that you run the 
executable. Let us know if that doesn't work. Also keep in mind that to get 
meaningful names for your tasks you'll want to annotate them with e.g. 
hpx::util::annotated_function (wrap your functions at hpx::async/apply 
callsites).


Mikael

I am interested in generating traces in OTF2 format to load into Vampir.
For that I am testing 1.4.0-rc2 with support for APEX and OTF2.

Building HPX with support for APEX works fine, great! I have also built
OTF2 (version 2.2) and passed in the APEX_WITH_OTF2 flag. I noticed that
otf2_listener.cpp.o was being built. I have no reason to believe the
resulting HPX does not have support for APEX+OTF2. Also:

./fibonacci --hpx:info | grep APEX
   HPX_WITH_APEX=ON
   HPX_WITH_APEX_NO_UPDATE=OFF

When I try this, no trace is printed, though:

APEX_SCREEN_OUTPUT=1 ./fibonacci

When I try this, a trace is printed:

APEX_SCREEN_OUTPUT=1 ./apex_fibonacci

I expected the first command to also print a trace. Is automatic
instrumentation of HPX with APEX maybe not working yet in 1.4.0-rc2?

otf2_listener.cpp.o was being built. I have no reason to believe the

When I try this, a trace is printed:

APEX_SCREEN_OUTPUT=1 ./apex_fibonacci

I expected the first command to also print a trace. Is automatic
