Means that the project is not relevant? It's quite sadly to hear, why in that 
case it was placed in GSoC ideas list? I spent a lot of time discovering it... 
Also, mentors who was watching my draft didn't notified me.

I think the libgeocomp project must have been deprecated by now. The
chap who was in charge of it has since left the HPX group and is no
longer involved.

I'm not sure it's a good idea to pursue this one - any other mentors
disagree?

The Newtonian Physics Sandbox project is available until someone

I haven't seen any proposal this year yet. In my experience they
usually come in hours before the deadline. That said, acceptance is,
as with probably all GSoC projects, conditional to a vote from all
mentors. So having no competition doesn't mean a free ticket. The
proposal still needs to be good. Let me know if I can answer any
questions on it.

Thanks
-Andi

interesting. Was that an event-based algorithm or was it force-based?

Yes, I'd still like to mentor such a project. Ultimately we'll do a
vote on all projects (we usually get way more applications than slots
for students), so your proposal would also need the support from other
mentors from the Ste||ar Group.

A good starting point, as Patrick has already pointed out, is to check
out the trunk of LibGeoDecomp, get it compiled and run the tests.

Thanks
-Andi

Cool, that sounds like a background that would make you a good fit for
this project.

Correct, no such toolbox has been written. LibGeoDecomp has been used
in similar settings, e.g. for smoothed particle hydrodynamics or for
simulations of granular gasses, but these were always rather
specialized codes and nothing generic or really reusable.

I thing the first step, as it is so often, is actually to check out
the trunk from https://github.com/STEllAR-GROUP/libgeodecomp and see
if you can compile the library and run the tests.

Cheers

I didn't work on LibGeoDecomp while I was ramping up at Google. It's
not deprecated though. ATM I'm working on getting it to work with HPX
trunk again.

Yeah, I'm rarely on IRC these days, sorry about that. Documentation is
sparse, I believe the best source for that is usually the unit tests.
How can I help you, what do you need to know?

I think the libgeocomp project must have been deprecated by now. The
