[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!

[MLC@Home] MLC@Home inconsistent work generation for the next few months

TL;DR: MLC is entering an analysis phase, and new work will be bursty and inconsistent for at least the next few months. Please adjust your BOINC contributions accordingly!

Over the past several months we (MLC@Home admins) have turned our attention to the analysis of the results our volunteers have contributed. With the completion of DS1/2/3, and the partial results of DS4, we're really excited to polish up some papers and publish some results. (Along those lines, look for an announcement of availability of all 5 tiers of DS3 datasets later today or tomorrow, just need to set up a torrent for 1.3TB DS3-10000 dataset).

In addition, DS4 results are larger than we anticipated and also don't require as much computation time to complete. So when we release DS4 WUs our volunteers churn through them in only a few days time while also filling up the disk space on the server. This is a great problem to have, but also forces us to be judicious about sending out work to make sure we've archived enough old results off the server to handle the influx of new results.

The upshot of all this is that we don't have the resources to both do the analysis and prepare/maintain consistent meaningful work units. So rather that just keep pushing out work that'll keep WUs flowing but has less scientific meaning (such as creating more DS3 networks just to create a bigger dataset), we'd rather just announce that MLC@Home WUs work will be inconsistent for at least the next several months. We expect to release batches of DS4 WUs every few weeks, but it won't be the constant work availability you're used to from the project over the past two years.

We realize this will cause us to lose some volunteers, but that's why we're trying to be upfront about this now so that everyone can decide if and how to allocate their BOINC contributions accordingly. We hope that you'll consider leaving MLC in your projects list and help us crunch WUs when we have them, but understand if choose not to.

A few key things to note:



We hope this announcement reassures you that we're trying to be good stewards of the trust and resources you provide us as BOINC volunteers. We're really excited by the science and humbled by your support since we started in July 2020, and we hope you understand as we move into the next phases of our work. As things change we'll make more announcements here and on our Discord.

[Milkyway@home] Nbody WU Flush

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

[MLC@Home] Spring 2022 MLC Project Update: DS2 Complete edition!

It's been a while since we've posted an update, but that doesn't mean the project has been idle! If you've been following on our Discord server you'll know we've continued to make progress, and thanks to our volunteers, today is a day of celebration!

Here's a summary of the current project status:

Summary



Please note that there are still DS2 WUs in the work queue, we ask that you please continue to crunch them, as it's always better to have more samples as spares. However, we don't plan to queue up any more DS1/2/3 WUs, and all new WUs added will be DS4 or later. This applies to the GPU queue as well.

We're really excited for DS4 WUs going forward, and it should help show our theory that similar networks cluster in parameter space in both feed forward and CNN-based networks as well as the RNNs used in DS1/2/3. Beyond DS4, we have some ideas but have nothing concrete at the moment. We'll keep you updated as we move forward.

Thanks again to all our volunteers for supporting the project and helping science.

[QuChemPedIA@home] Presensation of our work

Hello everybody.

In the context of the Molecular Modeling and Drug Discovery (M2D2) talks, organized by the Valence Discovery lab, Thomas Cauchy made a presentation of our work. This video is intended for researchers but Thomas makes, as always, an important effort to popularize the subject. I hope you will enjoy it !

[Milkyway@home] Server Downtime March 28, 2022 (12 hours starting 00:00 UTC)

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 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.

Best,
Tom

Thanks again for all your support.

[NFS@home] New record penultimate prime factor

NFS@Home has found a new record penultimate prime factor! 7,889M, which is a portion of the number 7^889+1, splits into 151-digit and 160-digit prime factors. This 151-digit prime factor beats the old record, a 147-digit prime factor of 12^293+1. Congrats to all contributors who helped set this new Cunningham project record!
