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.

Problems with Receiving Email for Resetting Passwords
Hello all,

It has come to my attention that there are some people who are having trouble resetting their passwords. More specifically when requesting a link to reset their password, the email with the link to change their password never arrives in their inbox or spam. At the moment, I have been able to reproduce this problem with gmail accounts and some temporary email accounts. So far, I've only been able to get my university email account to receive a password reset link. While I will continue to troubleshoot this issue, I humbly request help in this matter. If you could request a password change and tell me whether or not you receive an email with the password reset link, as well as what email type you are using (gmail, hotmail, yahoo, edu, etc.), it will help me immensely with identifying the root of this problem. I am not asking for you to change your password; I only need to know if the email arrives.
Thank you in advance for your assistance in this matter.

Leaving MilkyWay@home
Hey Everyone,

I want to thank you all for your support and encouragement over the last 7 or so years that I have been a developer and scientist on this project. Unfortunately, it has come time for me to move on to the next phase in my life and career. Tuesday, April 30th will be my last day working in an official capacity on the MilkyWay@home project and for RPI.

Over the last several months, I have been doing my best to document and pass my knowledge down to the current MilkyWay@home scientists and developers, so I am confident you all will be in good hands.

I wish you all the best, and thank you all again.

Best,

Jake

New runs of MilkyWay Nbody out
Hello all,
I just wanted to let you know that new runs for the newest version of the MilkyWay@home Nbody program have just been released. The names of these new runs are:
-de_nbody_04_23_2019_v176_40k__data__1
-de_nbody_04_23_2019_v176_40k__data__2
-de_nbody_04_23_2019_v176_40k__data__3
I apologize for any inconveniences over the last few days. If you have any issues with these runs, please let me know on this thread and I will try to sort them out as quickly as I can.
Just so you know, some of the changes we made for this nbody version take runs that would've taken extremely long times to compute and return success immediately. As such, credit for nbody may be a little strange until the server recognizes the new average runtime. Also note that there is no longer support for multi-threaded.
Again, thank you all for your continued support.

New version of MilkyWay Nbody
Hello all,
We have just released a new version of the MilkyWay@home Nbody application. We have not put up new runs for this yet. We will be putting up new runs next week or the following week. Thank you for your support!

New Separation Runs
Hey everyone,

There was a problem with the previous separation runs that was causing some command lines to overflow. I have changed the bundle size of the new runs, so that shouldn't be a problem anymore. The previous runs have been taken down.

The names of the new runs are:

de_modfit_80_bundle4_4s_south4s_0
de_modfit_81_bundle4_4s_south4s_0
de_modfit_82_bundle4_4s_south4s_0
de_modfit_83_bundle4_4s_south4s_0
de_modfit_84_bundle4_4s_south4s_0
de_modfit_85_bundle4_4s_south4s_0
de_modfit_86_bundle4_4s_south4s_0

These new workunits will crunch a little faster than the previous versions, and credits are assigned accordingly.

Thank you all for your patience during this transition period!
