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.

Continued NBody Runs (07/29/2020)
The last set of NBody runs have just converged beautifully. We are currently working on writing the paper to publish these results. In the meantime, we will be replacing these runs with another set:
Thank you all so much for your support. We would not be able to write this paper without your continued assistance.

New Runs for MilkyWay@home Nbody Simulations (07/29/2020)
I just wanted to let everyone know that new Nbody runs have been put up on MW@home. The last set of runs started converging nicely, so we are confident this next set of runs will converge as well. The names of these runs are:
Please let us know if you have any trouble with these runs. Thank you all for your continued support.

Scheduled Internet Outage July 28th,2020
On July 28th, our server will be temporarily inaccessible due to a scheduled campus-wide internet outage. As such, job queues may not update for the day. However, everything should return to working order by the next day. We apologize for any inconvenience this may cause.

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.
