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.

Server Maintenance 12:00 PM ET (16:00 UTC) 9/23/2022
We've been noticing some occasional long loading times and brief connection disruptions with the server, so I'm going to take things down at noon ET tomorrow (4PM UTC) and reboot the server. It should be back up pretty quickly. Hopefully this fixes the issues we're having.

New MilkyWay@home Scientist
My name is Kevin Roux and I will be working with Dr. Newberg for my Ph.D thesis. I look forward to working on this project and working with you all for the next couple of years.

Hi, my name is Hiroka. I am a PhD student working with Prof. Newberg. As part of my theses, I am working on the nbody project.

Nbody WU Flush
I'm going to turn the project off for a little while to cancel a bunch of WUs. There's no easy way to cancel only Nbody WUs (unless I want to sit and cancel them 999 at a time, because of how BOINC servers are set up), so I'm just going to cancel ~75% of the currently available jobs. This will reduce the enormous Nbody backlog and hopefully get things flowing more smoothly.

Server Downtime March 28, 2022 (12 hours starting 00:00 UTC)
I will be turning off the mysql DB for the server at midnight UTC (8PM EDT) for 12 hours. Last time I kept some processes running, but turned off the WU generators in order to give things time to catch up from the drive failure (they are currently still off). I don't think that the server finished rebuilding then, so I will be turning all MW processes completely off for 12 hours, and then hopefully by the time I turn things back on again, the drive will have rebuilt.
If you only tune in to the BOINC notices, apologies for the massive drops in RAC lately. These are related to a hard drive failure that we are still in the process of recovering from.
Thanks for your patience. I know that this has been very frustrating for all of you, and it has been frustrating for me as well.
