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.

Server Outages
Hi Everyone,

I'll be working for the rest of the night to try to resolve the large number of workunits waiting for validation. This will involve the server going up and down for maintenance, and certain processes may be turned off for periods of time tonight. I'm hoping that things are resolved tonight, but it is definitely possible that things may not be resolved by tomorrow.

Thanks for you patience and support!

Planned Deprecation of TLS 1.0/1.1
To Sum Up: Older machines/BOINC clients may encounter issues after 12/17/2021. In order to prevent this, update your BOINC client to at least ~~7.210~~ 7.2.10 by then, as well as your OpenSSL and curl libraries if necessary.

Hey Everyone,

We recently renewed the cert for the server, and we realized that the server is still supporting TLS 1.0/1.1. These services are out of date and are security hazards. We are going to end support for these services as of Friday, December 17, 2021.

What does this mean for you as a user?

Older clients may still be using old versions of SSL that need TLS 1.0 or 1.1. Once we stop supporting these services, these older clients may encounter issues when trying to communicate and/or get work from the MilkyWay@home server. In order to prevent this, you should update to at least the ~~7.210~~ 7.2.10 BOINC client.

Additionally, some libraries rely on old versions of TLS. The most common of these are old versions of OpenSSL and curl. If you are running old versions of these libraries, it may be time to update them. Other libraries might also cause issues, so we will keep track of any problems that people run into here.

Overall these issues are relatively easy to fix and should only impact older systems, especially those that have not updated their libraries or BIONC clients in a long time.

Best,
Tom

News General
Hey Everyone,

I think that it would be useful to have a general thread in News for random problems or notices that don't relate to any other thread, or don't require their own thread. Recently we've been using the Validator Outage thread for this, but it's better to have a designated place for it.

Feel free to post comments/concerns/general project status-related thoughts on this thread.

Best,

Scheduled Outage 11/16/21 3PM EDT
Hey Everyone,

I'm going to take down the server at 3PM EDT tomorrow. The outage should only be a couple hours at most.

Temporary Outage 11/5/2021 5PM EDT
Hi Everyone,

I will be taking the server down at 5PM today in order to delete the millions(!) of spam accounts. This shouldn't take too long, but the server may be turned off for a couple of hours.

Thanks for your help, and your patience.
