And an unknown list of future projects that might be distributed from that server.

The other thing that's probably worth investigating is alternate drivers. AMD has not been particularly good at providing reliable drivers for many of their past GPUs.

C'mon :e) , I hope we have no kids here and everybody understand prolonged effect of this ban. Just remove it after 1 month or so. Its not the first time when we getting projects with problems. I always do this way.

As far as I see this discussion we already checked a few versions of drivers and few generations of cards and got the same result. Makes no sence to waste time to play with it. Looks like Nvidia cards have no issues so let them do this job and we do something else.

The project owner could easily reconfigure things to block AMD GPU from it.
Doesn't fix the fact that there is something broken either in the core or the project.

Nah, project owner needs to reply to my request, and then we can bring that project back to testing stage to see what is going on. Unfortunately owner is missing in action for a moment :)
No one is gonna ban anything without investigation ;) project ran fine with older fahcore versions and since initial testing we had 7 new revisions to the fahcore.
We have a lot of things going on at the same time which might improve the constraint system. Might

So the project owner didn't reply to you in one week? Oh, what a rush... ))

Guys, I'd say its not smart to waste machine time like this. If you see 70-90%% failure rate on AMD and no failure on Nvidia so its obvious that this job is for Nvidia cards and AMD cards shouldn't receive it. Testing, investigating and other internal kitchen stuff is on testers, not for our eyes. Its not our business. We do calculations and we'd like to get math what we can do. We found a problem, we reported it, thats it. Its enough to make quick desision to shift calculations to platform that able to do it sucsessfully.

First off, there is no 70-90% failure rate on AMD, period. We have couple of people reporting this on couple of models. For certain people it is high failure rate, not for all. OP had issues with 16448, yet we ran this project on 3 different AMD cards (including one which OP has) and we did not encounter a single failure.
Second of all, when WU fails, it sends it back to collection server with partial credit given. That WU is straight away put back into queue for another folder. If a WU fails certain amount of times, it will be blacklisted for further inspection.
Yes, it is unfortunate, that project owner is on holiday (you know UNIs have holidays during the summer) or maybe is tied up with other stuff (some of the scientists are in the season of defending their thesis), but it is not end of the world, so calm your horses, guys, everything will be OK

Perhaps another valuable data point:

Since August 3rd, my RX580 didn't manage to return ANY assigned WU successfully.
Before that date, it was already processing project 13421 exclusively for days. Usually successfully, with some odd streaks of faulting several WUs in a row with things like:

'Force RMSE error of 22.695 with threshold of 5'
'Potential energy error of 46.9965, threshold of 10'
'An exception occurred at step 224142: Particle coordinate is nan'
'NaNs detected in forces. 0 0'
'Discrepancy: Forces are blowing up! 0 0'

And on August 3rd, coincidentally(?) when project 16600 joined the mix, not a single RX580 WU completed anymore on that rig, same mix of error messages as above, but just for every single WU (which all happen to be of either project 13421 or 16600)

Code: Select all

No hardware or software changes, rig is active 24/7, restart didn't change behavior.

Advice? Anything a folder can do to make this GPU doing something productive, or just disabling the GPU for a couple of days and see if things get fixed?

(It still burns an extra 150 W, but is it worth it just for handing in a "FAULTY" WU every 30 minutes which other GPUs, according to muziqaz, have no problem returning properly?)

Based on https://apps.foldingathome.org/wu#proje ... e=21&gen=0, your GPU had an error and so did somebody else so I can't tell if the WU is really bad or there's a problem in your system and somebody else's.

project:16600 run:0 clone:112 gen:402 is no help, either.

I don't know much about project:16600

Keep it running! If everyone starts to blacklist WS and thus WUs, no one will notice the problem. So there will be no improvement in the future and it may even get worse.
For amd owners it's even worse, our failed WUs get diluted I think the mass of Nvidia cards (OS stats Page is giving me an error right now so can't give you the actual numbers...).

I know it's annoying to see all this failed WUs, but keep folding!

FAH has a team who are collecting failure reports like that one. They've been fixing the high-probability errors but the list is long and isolating a fix for each one often takes additional testing.

P134yy is a replacement for p134xx but with a shorter list.

We see multiple reports of the problem with good description in this topic and we made our reports - it's enough to escalate the investigation and bring the problem to attention of scientists admins and testers. And thats it! All other tests/analitics/improvements are on them.
Thousands of other users who don't monitor their clients and dont read this forum will generate more faulty returns. But for us: this project is done and we shouldn't waste our calculation powers on this anymore. Hundreds of our faulty returns is not important, cos its all the same. It doesnt matter how many faulty returns we do: 20 or 200. If we are the only people with faults it means that its just a local problem (software/hardware/combo) and it makes not much sence to investigate it and no sence for us to waste our resources if all other projects are running with no issues.
Its much more important IF faults happening on many OTHER machines. Its an indicator that its not just a local problem. Testers/admins/scientists should investigate it. We give them the signal and now its their turn to check and do the job if necessary.

As I said above, the error reports are prioritized by their frequency. "Forces are blowing up" has been reported by you and by others, and they represent a small fraction of all errors reported by p1342* Yes, Testers/admins/scientists should investigate it and they will when they've finished working on the problems that are occurring at a higher rate.

I do not believe it's a local problem, but it might be. Some percentage of WUs crash spontaneously but they also crash because of bad drivers or because of unstable overclocking and for other reasons. If there's enough information in your error report(s) to figure out which is applicable, thank you for the report(s). ... except if it's a spontaneous case.

I wasn't thinking of blacklisting the WS, I am considering pausing the RX580 slot to save the energy.

It only gets WUs from project:13421 and project:16600 for 10+ straight days now, and never completed a single one, always sends them back as "faulty" after working on them from somewhere between 0 seconds and 2 hours.

I wonder if these projects trigger some very specific problems/properties of certain (individual) cards - think race condition or even "rowhammer" and the like - because when and how each of these WUs fails, at least on my system, seems very statistically distributed over time, and retries bail out at very different step counts, and it's more the norm (and not the exception) that the WU might reach the next checkpoint on retry.

That being said, one WU just made it to 73% after two "restart from last good checkpoint" messages before "ERROR:114: Max number of attempts to resume from last checkpoint reached." and being sent back as Faulty.

I can't find a setting to increase the numbers of retries, it doesn't seem to be max-unit-errors which defaults to 5 instead of 2 or 3.

If I could configure 10 retries instead of 2, it might actually complete about half of the assigned WUs.

That setting is set on the Project level and is present in the WU itself. By default, the value is 2 but that can be changed by the Project Owner. From observation, it is a setting that is rarely changed.

I'm seeing an RX580 on Windows which is returning plenty of valid results on project 13421 without any restarts. Is it possible to get FAHBench to work on a chosen good work unit? (project:13421 run:3765 clone:27 gen:1 works on the RX580 under Windows here.) Or I could test one of the 16600 WUs which is NaN'ing on UofM.MartinK's RX580.
