Folding@Home is beta testing a new GPU folding core which supports both CUDA and OpenCL. It gives a speed boost on all Nvidia GPUs, especially on the lower core count GPUs: 1660 Super:31%, 1080Ti:25%, 2080Ti:20% or 3080:14%. Due to the quick return bonus, even though the relative speedup is higher on the lower tier cards, the actual points boost will be higher on the bigger cards. Looking forward to this going live so my 1660 Super folds faster than the RX 5600 XT.

Unfortunately, low atom count work units still under-utilize the bigger cards, but they're working on segmenting GPUs better in the future, so they'll get work units more suited to their core count.

Edit: I tried running BOINC on a couple of Android devices, but while I did return some valid results in the WCG Covid-19 project, I got a lot of work units that failed due to segfaults, so I gave up. It was a cheap phone and a cheap Asus pad, so they might have had instability in anything from Android to the storage.

Folding@Home has released the CUDA folding core. There are also some bug fixes for AMD cards, but with this the Nvidia cards have an even bigger advantage for folding.

Yeah it's super dumb (in a good way!). I went from 540k PPD to over 1.05m overnight. Absolutely silly.
1660 Ti owners got a 270% improvement or something. My 1660 Super is now faster than the best AMD card.

AMD's engineers better get working on those ROCm drivers and see if they can optimize them for folding without hurting the more memory intensive compute tasks.

Is there any reason why I *shouldn't* run Folding@Home on my CPU?
If you have a low core count CPU without AVX support, you probably shouldn't CPU fold. Also, if your CPU clocks down too much, it starts to bottleneck the GPU folding - at least it used to under OpenCL. So if you are GPU folding with an old CPU you might want to see if your toal system PPD rises with or without CPU folding enabled.

CPU folding is less energy efficient than GPU folding, so if you need to run your air conditioner, then you should probably pause CPU folding until the weather gets colder.

Even so, Folding@Home needs CPU folders, so CPU folding isn't dead.

If you have a fairly modern Ryzen or Threadripper CPU with SMT, the most efficient number of threads appears to be 2 below the CPU's thread count, and subtract 2 threads per GPU. So if you're only CPU folding on a 32 thread Ryzen 9 3950X, the most efficient setup is folding on 30 threads. If you have one GPU as well, then 28 or 26 CPU threads is better. A Ryzen 5 3600 running a GPU is best run with 8 threads. CUDA might have changed this, so we might to check. The CUDA core still shows 100% CPU utilization, but this is just an active wait state, so real testing is needed to see if you can now fold with more CPU threads together with the GPU.

If you check the logs, you'll probably see many instances of the folding core automatically dropping down to 8 folding threads because it doesn't like a number of threads which is divisible by 5, 7 or other large primes.

Edit: Your CPU has AVX2, which means it should be pretty good for folding.

That's weird, which OS?

If you're already maxed out doing BOINC, it might not be worth the time to set up Folding as well, but I've never heard of hibernation being interrupted by folding. I do know that the "on idle" setting has very mixed results, especially with GPU folding, and that sometimes manually pausing the GPU folding or making a script for it works better than idle detection.

Folding is actually a bit time sensitive, especially the current "Moonshot" project sprints, which only gives you like 24 hours to complete a work unit. So if you don't use your computer most every day, folding might not be suited for it.

You might try to set the "disable-sleep-when-active" to "false" in the Expert tab in your client configuration. That would allow you to use Sleep, but you should check if the GPU core correctly resumes from checkpoint when it wakes up again, or if it just abandons the work unit.

The reason for this issue seems to be that Sleep and Hibernate doesn't store the contents of the GPU's VRAM, only the state of CPU processes, so FAH "solves" it by blocking the sleep function while GPU folding. It's apparently hard to program around too, because of the GPU permissions that Windows gives to applications. Same reason why you shouldn't be folding on Remote Desktop, but should be physically logged in. (You can start new GPU work units while logged into Remote Desktop, but if you log out it won't start a new one when the current WU finishes.)

now when I go to fold the CPU is running around the same but the GPUs are sitting on like, 10k each. Which is obviously not worth it for the electricity used. Does anyone have any ideas?
Does that persist across several work units and projects? Remember that the Quick Return Bonus is dependent on how quickly you return a work unit, and if you stop folding to fix a computer problem, the PPD will be low until you finish that work unit. The effect will be especially harsh if you just barely was making the Timeout before the crash, and now only is able to return the work unit within the Expiry time.

If you return a work unit after Timeout, but before Expiry, you will still get some credit but the WU will be re-issued to someone else. And if you return before Timeout, your QRB is higher the faster you return it.

COVID-19 Moonshot work units have especially short timeouts because they are so time-critical. Researchers are using the data to prioritize chemical compounds to synthesize and assay in-vitro. More traditional projects have longer timeouts on them.

Can you try pausing the CPU and see if the GPUs start working again? Two CPU threads should be dedicated to feeding the GPUs with work and sanity-chekcing their results.

If your PPD permanently dropped, then I'd suspect some kind of hardware issue. Have you asked in the foldingforum.org forums?

Folding work units are not supposed to be done by two folders. The only cases where a work unit is issued to more than one folder is if it passes timeout, it crashes, gets dumped or there's something wrong with the work server.

The servers validate the work on their own, because it takes relatively little computation to validate the folding work once it has been done.

Folding@home has quietly released a new client version (7.6.20), and there is now an ARM Linux / Raspberry Pi version as well: https://foldingathome.org/alternative-downloads/

e: Also they posted some science news: https://foldingathome.org/2020/10/20/covid-moonshot-sprint-4/

quote:

Just as we were doing this, something extremely unexpected happened: The chirally-separated version of the compound we started with turned out be 100 nM! That’s 25 times more potent (meaning you need 25x less drug to get the same effect in shutting down the protease) than what we thought we started from!

The exciting aspect of this is that we have apparently been working on an extremely potent compound series all along in Sprint 4, thinking it was “just” a backup series. All of the work we did has suddenly become much more important.

The starting materials we ordered from Sprint 4 have already arrived at the Weizmann, and the London lab is already hard at work synthesizing new compounds based on Sprint 4 designs. We’re excited to be able to share the results with you once they start trickling in.

There is a security vulnerability that affects those who use the Folding@Home GUI prior to version 7.6.20 to control remote folding instances over insecure networks: https://foldingathome.org/2020/11/23/update-for-those-using-advanced-remote-client-management-configurations/

Basically, the folding client or an attacker on the folding client's network could trick the GUI into running arbitrary code. This doesn't matter to those who fold on their own computers, but maybe if you're running folding on your webserver or something and just opened it up to the world.

In Folding@home, we are still #68 in rankings. Its compute power is now about 240 petaFLOPS, a shadow of the 2.62 exaFLOPS it was back towards the end of April.
They over-estimated the exaFLOP count for F@h, because they were counting a lot of institutional or company contributors who spawned a new instance for every work unit computed. Additionally, it took into account a too large time interval. If you look at the amount of points, the compute power has only dropped from about 1.2 billion per month at the April peak to about 0.9 billion per month now.

John Chodera from Folding@Home posted a status update about the Covid Moonshot:

quote:

To very quickly update where we are:
  • We have very potent lead compounds that show great antiviral activity against all SARS-CoV-2 variants of concern
  • The compounds appear to be very good in standard in vitro safety panels
  • We're working through an issue with pharmacokinetics with rodents, which have very rapid metabolisms. This is critical for drug approvals because preclinical work to identify appropriate safe doses for humans typically use rat and dog, and if you can't use rodents, you're generally forced to use primates instead, which would significantly slow down our entry into the clinic
  • We've been working incredibly hard to identify partners and funding mechansisms that will carry us through preclinical work (which can cost millions of dollars) into clinical trials (which cost many more millions) so that as soon as we nominate a clinical candidate, we can move it into human trials as rapidly as possible
The Folding@home sprints still continue! We're up to Sprint 8, but I haven't been releasing the dashboards publicly because we're still debugging some issues with the dashboard that lead to scrambling of the compounds in data display. As soon as we get these fixed, we'll get all of these dashboards online and make more regular announcements. Here's a (sadly scrambled) preview, though!

https://fah-public-data-covid19-moo...ined/index.html

The continued sprints will be vital for both aiding in the final replacement of problematic parts of the compound for improving rodent metabolism and for the further efforts to ensure second-generation compounds are active against multiple coronavirus variants.

An update from an Alzheimer related folding project at Folding@Home

One more note on this project. We've finished a first pass analysis on the data we collected for p18202 and have written a paper detailing this analysis and findings. While this paper is still in peer review for official publication, we've made the paper available via the biology preprinting server, Biorxiv. You may find the paper here: https://www.biorxiv.org/content/10.1101/2022.02.02.478828v1.Here are the highlights-

This project highlights the strongest genetic risk factor for Alzheimer's disease, ApoE. People with two copies of ApoE4 are ~12-15x more likely to develop Alzheimer's disease than people who have the more common variant, ApoE3. Our hope is that by understanding how ApoE isoforms adopt different conformations, and how those conformations lead to disease, we may be able to develop drugs that change or fix the conformations of bad-acting ApoE variants. While ApoE has been studied for many years, "seeing" ApoE has had a lot of challenges. For the first time, we present ApoE in atomistic detail. We find several interesting findings, including that parts of ApoE are highly dynamic, an underappreciated fact before now. We also find that many other parts of the protein adopt not one, but several stable conformations. We will continue to explore other ApoE variants (p18201 for GPU, 18210 for CPU), as well as explore this dataset in much more depth in future work.

A huge thank you to everyone who has contributed their time and energy to this project.

Since AMD is turning away from OpenCL support, and their recent drivers have been performing worse in OpenCL compute than older drivers, it's good news that OpenMM, which is used as the GPU compute core in Folding@Home seems to be getting support for HIP, AMD's own compute API. I don't yet know if this will also be integrated into Folding@Home, but I see no reason why it shouldn't. It's still a bit sad that AMD, unlike Nvidia, haven't provided any development support for making Folding@Home run efficiently on their GPUs, but I guess they have too much work to do elsewhere for paying customers.

Yes, it used to be that AMD had the best driver support on Linux, right? I'm not sure they're so bad at graphics, but if you're using AMD for compute, even in Windows, you'd better be using an old driver. I would have thought that AMD's interest in HPC would cause them to be more on the ball regarding compute driver support, but here we are.

My understanding is that Nvidia's OpenCL driver also sucks, though perhaps not quite as much as AMD's.
My only experience is with Folding@Home, and while the CUDA code is more efficient than the OpenCL code, Nvidia's drivers haven't regressed in OpenCL performance like the AMD drivers have. You can still force the client to use OpenCL and it will be reasonably efficient on an Nvidia card, but CUDA is better - especially on smaller cards.

While AMD haven't dropped OpenCL completely from their drivers, support for OpenCL has been dropped from Radeon Rays and Blender Cycles X, so they might no longer be validating OpenCL performance. It's likely that they'll drop OpenCL support eventually.

I've never heard of one. The problem is going to be bandwidth. If she wants to do a community service she could sign up as a Bittorrent mirror for some obscure scientific content, open source distributions, etc. - in other words legal content. She could even earn "torrent-coins" for hosting, with some clients.

For example, some of the content on The Internet Archive has torrent downloads, and you might want to seed those files to help other people download them faster.

Another thing she might do is digitize movies and other cultural artefacts which aren't in the public domain for preservation for the future, but she can't legally open that up for other people.
