MLC@Home is a distributed computing project dedicated to understanding and interpreting complex machine learning models, with an emphasis on neural networks. It uses the BOINC distributed computing platform. You can find more information on our main website here: https://www.mlcathome.org.
Neural Networks have fuelled a machine learning revolution over the past decade that has led to machines accomplishing amazingly complex tasks. However, these models are largly black boxes: we know they work, but they are so complex (up to hundreds of millions of parameters!) that we struggle to understand the limits of such systems. Yet understanding networks becomes extremely important as networks are deployed in safety critical fields, like medicine and autonomous vehicles.
MLC@Home provides an open, collaborative platform for researchers studying machine learning comprehension. It allows us to train thousands of networks in parallel, with tightly controlled inputs, hyperparameters, and network structures. We use this to gain insights into these complex models.
We ask for volunteers to donate some of their background computing time to help us continue our research. We use the time-tested BOINC distributed computing infrastructure — the same infrastructure that powers SETI@home's search for alien life, and Rosetta@home's search for effective medications. BOINC is fun — you get credit for each bit of compute that you do, with leaderboards and milestones. All while helping further open research. Please follow the link below to join, and happy crunching!

Testing updates to backend services again
We're going to be testing some new backend server updates again this weekend. Last time this lead to some instability, but we've learned quite a bit from that and have taken steps to make sure it doesn't happen again, with an easy and quick revert path if necessary. There may be some small interruptions, but nothing serious,. There is also nothing you need to do on the client side, this is all on the backend.
Wish us luck, and we'll be watching the results like a hawk for any new issues.

Lab network maintenance Nov 9
Overnight Nov 8 to 9 we'll be performing some brief preventative network maintenance. The server and site will be inaccessible for an hour or two, but shouldn't last longer than that. No action is required by the end user, and we'll be back soon!

This Month in MLC@Home
Notes for Oct 23 2021
A monthly(-ish) summary of news and notes for MLC@Home
It's been a while since the last update! But there's been a lot going on. From DS2 slowly working through its backlog, to backend updates for maintainability that went a little awry, DS4 backend work, and DS3 analysis.
First, two weeks ago we had a mishap with the WU generation, and "continuation" WUs were sent with the wrong parameters leading to computation failures. It took us a few days to fix and clear up, but no data was lost. We've been updating and modernizing our backend scripts to consolidate them and make them less fragile (this is a good thing for maintainability!), and one of our updates went awry. Thank you for your patience while we worked it out. We've had a pretty good track record until now, so I hope you'll continue to support us in the future despite this setback. We're looking for new ways to test these further to avoid similar issues in the future.
The majority of the work over the past few months has been analyzing DS3 data. We've been updating the existing paper with the full DS3 analysis. It is disk, bandwidth, and memory intensive on our backend, and sadly isn't quite as easy to break up into WUs to distribute over BOINC. In fact, just tar/gzip-ing the entrie DS3 dataset (2.6TB) takes over 24 hours, since it's over 4 million small files. We will be making all of DS3 this available as a torrent soon. I've been posting updates on this on our Discord server if you're interested.
Since we've been focesed on DS3 and modernizing our backend/management scripts, DS4 has suffered. I wish I could say that DS4 WUs are flowing but they aren't yet. Everything is in place, we just need to start the tests.
Thanks again for your continued support, and know that while these updates have been coming slower, that doesn't mean work isn't being happening behind the scenes!

Current WU issues, working on a fix
A short note that we're aware of the issue with WUs coming from the CPU and TEST work queues (the GPU queue appears fine at the moment). This is due to a server-side issue related to some cleanup and upgrades I've been doing behind the scenes that appears to have gone haywire, and since it initially seemed to be working I didn't catch it immediately, leading to compounding the issues.
This is unacceptable and I apologize. While this had been tested, this failure mode was unforeseen. You rely on us to keep things running smoothly, and I failed you.
Over the next 24 hours we'll be sending out cancellations for the corrupted WUs, and may stop/start the service a few times while we try to clean things up. Please bear with us and thanks for your patience.
I stress : no data was lost, and the nature of the failure is to fail-fast on the client, so there is little to no wasted computer cycles.
Thanks again, and we'll do better in the future.
