Constellation is presently by invitation only, it does not yet have a public project.


Orbit has had no tasks for some time - it is very intermittant.

Einstein is an Astrophysics project, not an Astronomy project.

None of the multiple application projects run Astronomy apps.

Message 45547 - Posted: 13 Jan 2011, 15:12:36 UTC - in response to Message 45519.  

the real point is to find a model for the Milkyway's potential


By potential I take it you mean mass and velocity,
and MVmilkyway - SumMiVi = dark matter mass X V (i for individual stars, dust, planets, moons...)?
No, I mean the gravitational potential.

Is this new update to separation 0.50 going to break all of us with the optimized applications? I'm running Fedora Linux x86_64.

Lately, tasks continue to run and finish, but there are a a lot of "validation inconclusive" results.

My current applications are:
milkyway_0.18_sse4.2_x86_64-pc-linux-gnu
milkyway_nbody_0.07_x86_64-pc-linux-gnu

Those are really old. That nbody I don't think should never validate; something changed after that.

Hi,

a lot of MilkyWay@Home v0.50 (cuda_opencl) de_separation
ending with computing errors! I have updated the NVIDIA Geforce GTX 285 from 260.99 to 266.58, running two cards on INTEL i7-965 3.2GHz quad, 8 processors, MS Vista 64 bit, SP2.

The computing errors are still there.

Kind regards,
Ronald

Hi,

tasks MilkyWay@Home v0.50 (cuda_opencl) de_separation with ....fix_1 ending on my NVIDIA Geforce GTX 285 cards with comuting error, ....fix_2 is always running fine on these cards.

I saw, that ... fix_1 is running fine on ATI-Graphic cards.

Hi,

if you need some more infos about our Constellation platform, just ask me. But perhaps not in this thread, because I think it's offtipoic then.

And yes, we're not public yet, but we work on it.

I think I know what the problem is. My formula fell apart for those size workunits with those GPUs.

I'm aware. I'll fix it as soon as I can. My main development machines are all sort of ripped apart right now.

Message 45766 - Posted: 25 Jan 2011, 15:54:30 UTC - in response to Message 45567.  

My current applications are:
milkyway_0.18_sse4.2_x86_64-pc-linux-gnu
milkyway_nbody_0.07_x86_64-pc-linux-gnu

Those are really old. That nbody I don't think should never validate; something changed after that.


OK, I updated to:
milkyway_0.50_x86_64-pc-linux-gnu__sse2
milkyway_nbody_0.21_i686-pc-linux-gnu__sse2

For some reason, if I let BOINC go back to stock, it doesn't use the sse2 app for NBody. So, I'm forcing the i686 SSE2 app with my app_info.xml file.

As long as someone posts a thread such as "Updated MW to version 0.50" in the News forum, my RSS reader will alert me so I can update my applications.

There aren't any non-SSE2 N-body applications.

I wasn't sure because it's not listed as such on the applications page.
http://milkyway.cs.rpi.edu/milkyway/apps.php

If everything requires SSE2, then simplier to just leave off the "(see2)". In 2011, I'd bet 99.9% of the CPUs attached to this project support SSE2.

Thanks a lot for your explanation... It gave me a clearer picture... and hope our efforts are well put then!

Good luck to us all.

Any plans to suport GPU work on OSX? I have a GPU I would love to put to work on this project.

Apple's OpenCL implementation seems to not support doubles for GPUs (at least for ATI) so for now it can't work.
