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.

New Runs for MilkyWay@home Nbody Simulations (07/07/2020)
The last set of N-body runs we set up started converging to compact progenitors due to an overly restrictive data histogram. We have fixed the data histogram and placed new runs up on the server:
Please let us know if these runs cause any problems, and thank you all for your support.

New Separation Runs 6/19/2020
I have put up the following separation runs:
And I have taken down the following separation runs:
The new runs are copies of the previous bgset_2 runs, in order to verify our results. Since the stripe 84 and 85 runs in the last set went a bit wonky after a couple weeks, I expect the same to happen here. I will keep a close watch on these forums, and when people begin to report errors from the runs on those stripes, I will promptly take them down. The errors that people are reporting on the bgset_2 runs should stop in the next couple days as the old runs all finish trickling in.
All of the testing runs have come down (there may be more in the future).
Thank you all for your continued support with this project. Stay safe (and sane) in these strange times.

New Runs for MilkyWay@home Nbody Simulations (06/08/2020)
We realized that the comparison histogram in the last set of runs contained incorrect data. As such we have replaced the last set of runs on 05/30/2020 with the following runs in their place:
We apologize for any inconvenience,

New Runs for MilkyWay@home N-Body (5/30/2020)
We are really close to releasing a new version of NBody. Hopefully, after the next two sets of optimizations, we'll have all the bugs in the newer version fixed. So for the time being, here are the new runs:
Thank you all for your continued support,

New Runs for MilkyWay@home N-Body (3/20/2020)
I am writing to let you all know that we have just put some new runs up:
Thank you all for your support,
