[RakeSearch] Processing of the square # 14 completed

Dear folks, processing of the square # 14 is fully completed! The square:

0 1 2 3 4 5 6 7 8 9 A B
1 2 0 4 9 8 B 6 A 3 5 7
5 8 A 6 B 1 4 3 2 7 0 9
8 A 5 B 7 2 9 4 0 6 1 3
A 5 8 7 6 0 3 9 1 B 2 4
9 3 4 2 0 7 A 8 6 1 B 5
6 B 7 5 8 4 1 0 9 A 3 2
4 9 3 1 2 B 8 5 7 0 6 A
B 7 6 8 A 9 2 1 3 5 4 0
2 0 1 9 3 A 7 B 5 4 8 6
7 6 B A 5 3 0 2 4 8 9 1
3 4 9 0 1 6 5 A B 2 7 8

have 800173600 orthogonal mates which puts it on the 11th place of the rating. This square close to square # 11 and square # 10 and together these square create a "bridge" between the squares with ~ 1 billion orthogonal mates and 300 millions orthogonal mates.

Thank you for participation and donation of CPU Time!

[PrimeGrid] Another 321 Mega Prime!

On 24 March 2022, 17:27:33 UTC, PrimeGrid’s 321 Prime Search found the Mega Prime: 3*2^18924988-1 The prime is 5,696,990 digits long and enters Chris Caldwell's “The Largest Known Primes Database” ranked 18th overall. The discovery was made by Frank Matillek (boss) of Germany using an Intel CPU with 1GB RAM, running Ubuntu Linux. This computer took about 1 day, 1 hour, 39 minutes to complete the primality test using LLR2. Frank Matillek is a member of the SETI.Germany team. For more details, please see the official announcement.

[NumberFields@home] BOINC Pentathlon



Welcome BOINC Pentathlon participants!

I would have posted earlier, but it was hard to reach the server after the initial onslaught. Things seem to be stabilized, at least for the time being...

[MLC@Home] DS3 Dataset of 1 million trained neural networks is available for download!

Hello volunteers!

Just a quick note that Dataset 3 is finally posted for download at our site https://www.mlcathome.org/mlds.html! Dataset 3 was completed a few months ago, but due to its massive size (2.25TB in all), and us emphasizing our own analysis over packaging the results for download, its taken us until now to make it available.

As a reminder, DS3 contains over 1 million trained neural networks (10,000/ea modelling 100 different automata), with a goal of analyzing how networks of the same size and shape encode similar-but-not-exact training data. Expect an updated paper soon!

We've always held that if the public is doing work for this project, then the results of that work should be made available back to the public to further science. As of right now, all of DS1, DS2, and DS3 are available to the public under a CC-BY-SA 4.0 license. We will do the same with DS4 when it completes.

DS3 is released via torrents due to its size. A few volunteers have already downloaded and seeded these (very large) files, so hopefully new downloads should be a bit quicker than us just serving from our singular server. The torrent files are listed on our website, and we're using the Academic Torrents tracker (see: https://academictorrents.com/browse.php?search=mlds.

Thanks again to all our volunteers! DS3 is quite an accomplishment!
