This Month in MLC@Home
Notes for Oct 23 2021
A monthly(-ish) summary of news and notes for MLC@Home

Summary
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!

Other News
We've also spent some time trying to port the new statically-linked client to CUDA and ROCM, neither of which have worked so far. The Windows CUDA client should be a standard recompile, but the Linux clients did not compile and link as planned and need some more work. We're starting to see SPAM in the forums. To combat this, we've disabled posting in any thread except "Issue Discussion" unless you have at least 100 credits. If you see things that look like spam in the forums, please press the report button to report it as such and we'll take care of is as soon as we can. The ARM64-specific client also isn't ready, because of a strange linker error with the size of the static binary. Honestly, we're not sure how to make it work. If you know about Linux linking with large relocations on ARM64, please get in contact with us. Until then, please run the ARMHF client (32-bit) on 64-bit ARM systems. Many thanks to Delta for his tireless work on modernizing out backend. We already have a new database access for both the BOINC database and our MLDS-specific MongoDB database thanks to his work, and soon we'll be consolidating 21 different scripts into a small handful. Reminder: the MLC client is open source, and has an issues list at gitlab. If you're a programmer or data scientist and want to help, feel free to look over the issues and submit a pull request.

2021-10-22: yoyo@home, Project progress

An update for the progress on each sub project in yoyo@home:OGR-28is 89% completed (https://stats.distributed.net/projects.php?project_id=28).
It will finish around beginning of 2023 (https://stats.distributed.net/project/ogr_status.php?project_id=28).

Siever & ECM
I see currently no end in further demands for sieving and trial factorizations.
There are many many math projects which have needs for sieving and factorizations.

M-Queens
We are currently in the 2. of 3 parts and have there 70% done. So in total we are at 56%.
We started 2 years ago. So it might take another 2 years to finish it.

2021-10-21: ODLK1, Disk up

hi,

the new disk is up and running after less than 4 hours later.

This disk is were Boinc save all past and present data (not the DB, that is in another more faster one) and the downside of a Boinc installation is that space in that area will grown day by day.

As the old one last for more than 3 years, we have at least other 3 years of data to process before fulling this one :)

2021-10-20: ODLK1, New disk

hi,

in the next days it is planned to move the Boinc data from actual disk to another big one.

The operation will be long 2 or more hours and during that time the server will be disconnected from network.

So be sure to have the WUs you need or add backup Boinc project to use in the mean time

Thanks

2021-10-20: SiDock@home, BOINC client 7.16.20 solves the certificate problem for Windows

Dear all,

If you are running BOINC on a Windows computer, please update to a new version (7.16.20) of the BOINC client. The previous version stopped working recently because of an expired SSL file that prevented it from communicating with several BOINC projects, with the BOINC server, and with Science United. You can download the new version here: https://boinc.berkeley.edu/download.php

With best wishes,
Team of SiDock@home

2021-10-14: MLC@Home, 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.

2021-10-14: TN-Grid, Storage problem

The University's storage system (that we heavily use) is having big performance issues thus everything is painfully slow. I stopped the work generator, which actually was not working because of this. No new tasks will be generated until the assimilator will be able to move the finished results to the proper place. There is nothing else to do but wait until the problem will be solved, no ETA, unfortunately.

2021-10-10: WEP-M+2 Project, P2203:190000000 wu's (of 10000 trials each equiv.) processed!

Thanks to all the users. Please keep crunching!

2021-10-10: iThena, New Task Series for iThena OONI Probe - New Settings

A new job series has been introduced for the iThena OONI Probe application.

The job tasks in the new series, are named: OONI_TESTS_1D_T...

A parameter has been set in the new series:

Max Memory Usage: 256 MB
Previously the "Max Memory Usage" value was 2048 MB which was too high (a particular problem on 32-bit platforms).

In addition, the number of credits for completing a task has been changed to 8 (previously it was 2).

Clients can still receive tasks from the old OONI_TESTS_0D_T.. series. (there are still some left in the queue).

2021-10-05: QuChemPedIA@home, New scientific publication

Dear crunchers,

We are very pleased to announce the release of our latest publication associated with the quchempedia project.

Link : https://jcheminf.biomedcentral.com/articles/10.1186/s13321-021-00554-8
The article is freely available. Feel free to have a look at it even if some parts of the article are quite technical and intended for specialists.

The most important is that the results of this article are based on the calculations of this BOINC project!
With the molecules we generated and you calculated, it was possible to probe the vast space of chemistry.
You are mentioned in the acknowledgements but we would like to renew our gratitude to you here.

We have many more projects.

Kindly,
Benoit and Thomas

2021-10-05: BOINC, Windows communication failure: temporary workaround

Recently, the Windows BOINC client stopped being able to communicate with some projects and with Science United. This is because of an expired entry in a file called the "certificate authority bundle".

To fix this problem, download a new version of the file and put it in the

C:/Program Files/BOINC

directory.

This is a temporary fix. We hope to release a new version of the client that won't have this problem in the future.

2021-10-04: SiDock@home, Certificates and project communicating

Dear folks!

If BOINC on your computer experiencing a problem during project communicating, try to replace file ca-bundle.crt in programs directory of BOINC (C:\Program Files\BOINC\ca-bundle.crt, for example) by this file: https://srbase.my-firewall.org/sr5/download/ca-bundle.crt and restart whole BOINC processes or reboot computer.

Another threads on forum:
Peer certificate cannot be authenticated with given CA certificates
Wus not uploading
Transient Error
Communication deferred
100% block still crunching

Thank you for participation!

2021-10-03: YAFU, Vacation

I'm on vacation the next 2 weeks. So there is limited support for yafu during this time.

2021-10-03: RNA World, Happy New Year!

So you want any people trying to start an account or attach another computer to have to be able to read German? I can't, and therefore can't do anything useful work the page of text I get after a failed login. I can't post this as a normal message, either.

My task in progress is on a computer that has been unable to boot for about two weeks.

Is there any way to transfer the task in progress to the computer I'm using now, if I'm able to copy files from the original computer but not able to boot that computer? If so, how? If not, another three months of computer time wasted for that workunit.

2021-10-02: iThena, OONI: News: Statistics
