Welcome to MilkyWay@home

What is MilkyWay@home?

Milkyway@Home uses the BOINC platform to harness volunteered computing resources, creating a highly accurate three dimensional model of the Milky Way galaxy using data gathered by the Sloan Digital Sky Survey. This project enables research in both astroinformatics and computer science.

In computer science, the project is investigating different optimization methods which are resilient to the fault-prone, heterogeneous and asynchronous nature of Internet computing; such as evolutionary and genetic algorithms, as well as asynchronous newton methods. While in astroinformatics, Milkyway@Home is generating highly accurate three dimensional models of the Sagittarius stream, which provides knowledge about how the Milky Way galaxy was formed and how tidal tails are created when galaxies merge.

Milkyway@Home is a joint effort between Rensselaer Polytechnic Institute's departments of Computer Science and Physics, Applied Physics and Astronomy. Feel free to contact us via our forums, or email astro[at]cs.lists.rpi[dot]edu.

Planned Server Maintenance
Hi Everyone,

The MilkyWay@home server will be shut down at noon tomorrow (6/20). We plan on bringing it back online shortly after. If there are any problems, we will post to our social media accounts.

Thank you for your support!

NewER runs for Milkyway_nbody
Hey all,

Sorry, there was a problem with the newest runs for nbody. I've taken them down and replaced them with these runs:
-de_nbody_06_06_2019_v176_40k__sim__1
-de_nbody_06_06_2019_v176_40k__sim__2
-de_nbody_06_06_2019_v176_40k__sim__3

I apologize for any inconvenience. Thank you once again for your support.

New runs for Milkyway_nbody
Hello all,

Just wanted to let you know that a new batch of runs for milkyway_nbody were just put on the server. The names of the runs are as follows:
-de_nbody_06_05_2019_v176_40k__sim__1
-de_nbody_06_05_2019_v176_40k__sim__2
-de_nbody_06_05_2019_v176_40k__sim__3

If you have any issues or questions about these runs, please let me know. Thank you all for your support.

New Separation Runs
Hi everyone,

I put up some new separation runs so that we wouldn't be wasting GPU cycles while I am analysing the results from the last runs. The names of these runs are:

de_modfit_80_bundle4_4s_south4s_1
de_modfit_81_bundle4_4s_south4s_1
de_modfit_82_bundle4_4s_south4s_1
de_modfit_83_bundle4_4s_south4s_1
de_modfit_84_bundle4_4s_south4s_1
de_modfit_85_bundle4_4s_south4s_1
de_modfit_86_bundle4_4s_south4s_1

NOTE that these are very similar to the names of the previous runs, demarcated by only a "1" at the end instead of a "0". These runs have slightly different parameters, so it will be interesting to see whether or not they result in the same problems we were having at the end of the last runs.

If you have any issues with these runs please don't hesitate to post about it here. There are lots of great people on these forums who try their hardest to help solve these problems.

Thank you all for your continued support!
