Hello everyone,
We are preparing to migrate MilkyWay@home to a new server on 1 November 2023 at 2 pm UTC. This new server has better hardware (specifically more memory), which we expect will improve the performance of the website and the rate at which you can get new workunits. We are forced to perform this migration at a fast pace due to RPI requiring that we update the server OS to ensure proper security.
We expect that this migration will take one day to complete. If it looks like the…
Hey Everyone,
I'll be shutting the server down for about an hour or two tomorrow at noon EDT (4 PM UTC) to take care of the loads of WUs stuck waiting for validation. They are from leftover Separation WUs trickling in after the project was shut off. Unfortunately I do not think that credit will be given out for these stuck WUs, as they were turned in after the project was shut down, and the validator is not running to give people credit.
N-body WUs will not be affected by this, and all credit…
Hello everyone,
Thanks for your discussion on the other thread (https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=5007). Based on your input we have decided to turn off Separation this Tuesday. N-body will still be running, and we appreciate anyone who wants to help crunch work for that application! I am not able to give you an exact time estimate because it's not clear exactly how long it will take to properly shut things down; however, I expect it to be sometime around noon EDT (1600…
Dear Volunteers,
We are beginning to sunset the Separation project (note that this is different from the N-Body project, which still needs your help!!!). Thanks to your computational contributions, we have completed the goals that we set out to accomplish with this the project, so we are going to shut down the Separation project in the near future. We are planning on submitting a paper containing the final results of the Separation project to an academic journal in the near future. It is…
Hello everyone,
We will be running server maintenance on June 1st, 2023 at 11:30 AM EDT.
Maintenance should be done by the end of the day.
An announcement will be made on this thread when maintenance is over.
Thanks,
Kevin
Hello everyone,
RPI is conducting their annual CII power maintenance between May 8th and May 10th. As a precaution, we will need to shutdown the server during this time.
We will have the server back up and running as soon as possible.
Thank you,
Kevin
Hello everyone,
The following are the new runs for N-Body:
de_nbody_02_27_2023_v182_pal5__data__1
de_nbody_02_27_2023_v182_pal5__data__2
de_nbody_02_27_2023_v182_pal5__data__3
These are our first runs of Palomar 5 with data from SDSS DR17.
Please let me know if there are any issues with these new runs.
Thanks,
Kevin
Hello everyone,
Looks like the server had some issues. I rebooted the server and it seems like everything should be running as it should.
Thanks,
Kevin
Hey Everyone,
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.
Best,
Tom
Hello everyone,
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.

Hey Everyone,
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.
Best,
Tom
Hey Everyone,
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…
Hey Everyone,
I'm going to be turning the project off for roughly 24 hours starting at 1 PM EST (17:00 UTC) on March 25th. This time will do three things: 1) It will allow me to clear the transitioner backlog, 2) It will temporarily stop generating new WUs, so we can work on the backlog of WUs waiting for validation, and 3) It will help the server rebuild the replacement drive that we put into the machine on Monday.
There will probably be at least 12 hours of downtime during this where you…
Hello Everyone,
We will be taking the server down at 1PM NY time to do a reboot and ensure that the replacement drive is rebuilding correctly. We plan on being out for a couple hours at most.
Best,
Tom
Hey Everyone,
The server appears to be having some connectivity issues. Additionally, one of the drives on the server appears to have failed - luckily things are mirrored so we haven't lost any data. However, I need to make a backup of things, which could take several hours. Once everything is backed up I'll try to clear out this transitioner/validator backlog and get things up to speed again.
Best,
Tom
We have measured the original shape and mass of the dwarf galaxy that was ripped apart to make the Orphan-Chenab Stream! The paper is out today: https://iopscience.iop.org/article/10.3847/1538-4357/ac498a Eric Mendelsohn was the lead author on this study.
Professor Heidi Jo Newberg has made a ~14 min video explaining the topic here: https://www.youtube.com/watch?v=ma44b8-SLcA, and a longer ~24 min video with more information here: https://www.youtube.com/watch?v=eATUWTwdOgc

Hey Everyone,
It's finally that time! The southern sky runs from before have converged, and it's time to start new ones while we dig through all that data.
I have taken down the following runs:
de_modfit_84_bundle4_4s_south4s_gapfix
de_modfit_84_bundle4_4s_south4s_gapfix_bgset2
de_modfit_84_bundle4_4s_south4s_gapfix_bgset3
de_modfit_85_bundle4_4s_south4s_gapfix
de_modfit_85_bundle4_4s_south4s_gapfix_bgset2
de_modfit_85_bundle4_4s_south4s_gapfix_bgset3
And I have put up the following…
Hey everyone,
My name is Dylan DeNicola, and I recently joined the MilkyWay@home project as a Project Developer and Project Tester, so I wanted to introduce myself. I'm currently an undergraduate sophomore at RPI, and I'm working towards a computer science major. I plan on working on the development of the BOINC software for the project, and for now, I will be working on updating the server to the latest version of BOINC, getting our GitHub repos up to date, and doing general bug fixes. It's a…
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!
