Folding Forum

I don't think that limiting the number of cores will fix the problem, at least not on a permanent basis. But as Joe_H points out, there is a performance "knee" beyond which more cores do not do much good. But occasionally they do. My Ryzen 5950X will normally get only slightly more PPD tha...

I undervolt all of my big Ryzens (3900X, 3950X, 5900X, 5950X) in the BIOS to keep them cool. When you boot up, go into the BIOS and look for a setting for the CPU frequency and voltage. For my 3900X for example, I run Frequency: 3800 MHz CPU Voltage: 1.17500 volts If the voltage is too low or the fr...

I would like that, if you don't mind. On this Ubuntu 20.04 LTS install I've not gotten the Python 3 to work at all. I'm currently on: Python 2.7.18 This is a bit of a kludge, but I have it installed on 10 Ubuntu 20.04.4 machines, and it works reliably for Nvidia, and AMD also. See: https://github.c...

Hahaha - never mind I found Folding@Home in Ubuntu Software App as a snap app which installs everything - the client, the controller, & the viewer all at the same time. Nice! I find that running the SNAP version fails after a few weeks on Ubuntu 20.04, for some unknown reason. I thought at firs...

I was just wondering if the lack of cancer units meant they'd found something. No, I don't think there is a magic bullet. There are a lot of different types of cancer, and treatments for it. But I am very impressed with their science. It is the most advanced distributed computing project on the Int...

On my CPU work units on five machines, I am running one cancer and one Alzheimers at the moment. https://stats.foldingathome.org/project/16983 https://stats.foldingathome.org/project/18210 Two others are for improving antibiotic therapies https://stats.foldingathome.org/project/18417 https://stats.f...

There has been considerable progress with identifying the right compounds recently. And the NIH funding looks especially important.

But it was announced on Twitter. I hope they fill us in here more often.

On the flip side, I have a couple of Ryzen 5700G machines that do CPU folding well (Ubuntu 20.04.4). They have 8 real cores and 16 virtual cores also (the same as the 5800X), but only 16 MB of L3 cache, half of the 5800X. I am seeing around 350 kPPD on average, though at the moment 380 kPPD on P1695...

Thanks. I have tried it on 22 and 20 cores with about the same result. But this is a new machine, and I am using Precision Boost Overdrive (PBO) with a negative offset to cool the CPU a bit. Normally, it sets the voltage and clock automatically without problems, but I expect it has introduced a bit ...

It will run for a few minutes with low output (initially 3,3800 PPD, then rising to 200 kPPD, and then falling back to low), and then start over. This is on Unbuntu 20.04.4. 17:07:54:WU01:FS00:0xa8:*********************** Log Started 2022-03-16T17:07:54Z *********************** 17:07:54:WU01:FS00:0x...

NNP/MM is a hybrid simulation method combining neural network potentials (NNP) and molecular mechanics (MM). NNP can model the molecular interactions more accurately than the conventional force fields in MM, but it still is not as fast as MM. Thus, only the important part of a molecular system is s...

Thanks for the heads up. I am delighted to see it. I will put another GTX 1650 Super on it.

They certainly can look at compounds in a very fundamental way with Folding that is not possible with other techniques.

This is why we need anti-virals, and not just vaccines. Covid will be with us for a long time, and we need to hit it now.

You're still as fast with that 105W CPU (150W with PBO enabled equals about 200W system power draw), as a 1060 6GB, 1650 Super, or a mobile RTX 3050, which is probably the absolute lowest you can buy nowadays on GPUs. For the price of the AMD CPU system, you can buy a cheap Celeron system with one ...

Somewhat OT, but I have been adding Ryzen 5000 series machines to do the FAH CPU work for several months. I like the science, though I have a bunch of GPUs (GTX 1070 on average) on FAH too. But the peptides (similar to small proteins) do well on the CPUs, and they can accomplish a lot of interesting...
