The same thing happened 663 times, wasting 12h of time that could have been used for actual folding.

No overclocking. I've manually removed the WU from the folder, but kept the files in case they are needed.

Your cpu has 16 threads and is using 15 of them. (You do not include the configuration portion of the log, so I can't be sure, but the latest version, 7.5.1 should avoid this) Your Work Unit won't divide 15 ways. You can configure your cpu slot to use 16 or 12 CPUs.

AMD Ryzen 7 3700X, so 16 core with hyper threading.
The new version hasn't made it down gentoo yet, so the update will have to wait until that happens.

It might be nice to consider having the WU handle it and go down automatically to the nearest workable number of threads...

The client is written by a Computer Programmer, the WUs are written by Biochemists.
I am sorry you have not decided to install the latest client. https://packages.gentoo.org/packages/sc ... dingathome
I would set your CPUs to 12 or 16.

I would try comparing PPD and power consumption, between running with HT disabled (7 threads), and HT enabled (13-14 threads).
You'll need at least 2 cores (if not 3) reserved for non-fah things.
You'll notice, if you run 14, 15 or 16 threads, that your CPU will run at 100% load anyway (probably 13 to 14 cores will get you 95-98% load).
Chances are you'll see only very little improvement between running on 7 cores, vs running on 13-14 threads, as the CPU will run cooler, but if your CPU supports it, also at higher boost frequencies.

@Nuitari

First let me clear up what may be confusing from the above answers:

The current version of the folding client is 7.5.1
The cpu core will not run when using large prime numbers. Some projects will have trouble with a prime number as low as 5.

So 7, 13 or 14 will not work. You can, as Jimbo suggested, use 12 or 16.

Linux has a command called ldd which will list the dependencies needed to run the core. Open files and navigate to the FAHCore_a7 location where you should be able to right-click and select open a terminal and type or copy/paste the following:

Code: Select all

ldd FAHCore_a7
That will show you what, if anything, is missing and if you post the results here we can help solve any problems.

See the following post for usage of ldd & strings (your location will be different because you've used a non-default install):
viewtopic.php?p=309712#p309712

Your location may look something like the following but those are only guesses because your log doesn't show enough info:
/opt/foldingathome/cores/cores.foldingathome.org/v7/lin/64bit/avx/Core_a7.fah/FahCore_a7
OR
/opt/foldingathome/work/cores/cores.foldingathome.org/v7/lin/64bit/avx/Core_a7.fah/FahCore_a7

In this case, the WU is being partioned into 3x5x1 segments (-nt 15) so in this case, the factor 5 is essentially a "large prime" as far as GROMACS is concerned. Having the software use 12 of your 15 cores might be considered but there are a lot of WUs that successfully use the factor 5. Dumping the WU after this type of failure can also be considered, as opposed to retrying it.

Did the software retry Project: 14246 (Run 0, Clone 69, Gen 68) 663 times or did the same failure process that many different WUs? If it was the latter, what other projects were involved?

I recommend that you avoid the problem entirely by manually creating a CPU slot with 12 threads and another with 3 threads (or, if you don't have a GPU, a single slot with 16 CPUs).

I'm not enough of a GROMACS user to know what -rcon or -dds or the LINCS settings can do, but I'll alert the project owner and let him/her research that possibility. (and whether changing those settings can be applied to projects that can be assigned to an unknown number of threads.

I do run folding at home 7.5.1 (your post original version had 7.5.5.1)

It was the same unit that failed 663 times. The client should probably have dumped it on its own.

I've checked through the historical logs files and none of the project's WU ever successfully completed, but the client automatically sent it back to FAULTY

This is an example with a different WU:

So please report what happens when you try to run those same WUs with fewer CPUs? ... especially with even numbers of CPUs.

Project 14245 is also having the problem at 16CPUs. It works with 8.
Is there a guide somewhere for the syntax in config.xml ?

If you have more than one CPU slot, you can configure it like this
-<slot type="CPU" id="0">
<cpus v="6"/>
</slot>

If you want all the slots same (or you only have one), the <cpus v=N/> can go in the general section before the slots are defined.

I'm getting this issue as well though I figured it would be kind of a waste to only allocate 12 threads to a 128 thread dual EPYC system. I can't image what it's like for people with EPYC Rome servers with twice as many cores. For jobs that cannot handle many threads, is it possible to run multiples of them independently and concurrently? I am using a docker image of FAHClient v7.5.1.

Yes, you can run multiple CPU folding slots, each set to use some fraction of the threads you have available. Just don't have the total add up to more CPU threads than you have.

In the past there have been large WU's for CPU processing, and the CPU core would scale to over 100 CPU threads. But few people have large servers like an EPYC, and many have mid to higher end GPUs. So the largest projects in terms of number of atoms being simulated are targeted towards GPU processing these days.

Re: WU crashing infinitely

So 12cores -1for GPU makes 11 … Client tries to get out of the large by down sizing core count - unfortunately to a multiple of 5 which is unfortunate :( … some projects don't have issues with 5 -this seems to try setting the CPU slot as 9 which may resolve this issue and avoid problems in the future
