16600 consistently crashing on AMD Radeon VII

[UofM.MartinK]

OK, now I have the data of the last 85 WUs processed by my RX580.
TL;DR: there is no "two states" of the card. It's all intrinsic to the WUs as other posters already mentioned, and driver & clock speeds have no significant effect.

My original suspicion - card has a "working" and a "non-working" state - was a typical case of "data artifact" caused by too small N numbers, and some clusters, with p16600 at the "fringes" of a string of working p13421 made it appear like some randomly successful p16600 might have had the same GPU "fingerprint" (Power/Temp/Vdd/Clocks) condition as the p13421, but when actually matching times precisely, this turned out to be false.

Still, the clusters are very unlikely to have happened randomly, but the round-robin behavior of assignments (and re-assignments for faulty units) can be blamed for that.

Here the basic breakdown:

p16600: 38 WUs, 4 completed, the other 34 failed. All 38 had NaN exceptions (statistically distributed over processing time), median time to fail: 3489 seconds. The 4 completed - just by probability ("luck") - after 4-5 hours without hitting the project-internal retry limit, but again, also had at least twice NaN exceptions and resumed from a checkpoint.

p13421: 37 WUs, 7 completed, the other 30 of them discarded after 9-17 seconds, due to '0x22:ERROR:NaNs detected in forces. 0 0'.

p13423: 9 WUs, 1 completed. The other 8 of them discarded as above, after 9-17 seconds, due to '0x22:ERROR:NaNs detected in forces. 0 0'.

p16920: 1 WU, successfully completed.

Summary: In the last 48 hours alone, my RX580 (and most similar AMD cards, I assume) spent ~14 hours for useful computations, or ~18 hours if the one "completed" p16600 in this time window is actually useful (which I doubt, it might actually weaken the project results). That's 60-70% wasted time and energy. And this is going on since at least August 3rd.

Update: I now run a script which tracks the log in real-time, and if a "0x22:An exception occurred at step XXX: Particle coordinate is nan" is found, it dumps that WU. (Since FAHClient --dump doesn't seem to be able to communicate to a running client, the script is instead: pausing the slot, deleting the corresponding work folder, and then un-pausing the slot)

[bruce]

I'm surprised that the --dump <n> doesn't work but I don't use it. You have to know which WU needs to be dumped (if you run more than one slot). Please explain how you have tested it and what happens along with the client version number.

[UofM.MartinK]

I couldn't figure out how to give a running client the --dump command, with 7.6.13 under linux. It doesn't behave like --send-pause and --send-unpause etc, and preceding it with --send-command didn't help either. Using "help" while directly connected to the client via "nc localhost 36330" didn't reveal any dump command either.

It only seems to work if the client is stopped, then FAHClient --dump <WU> is run exclusively, and then the client re-started.

This disturbs the other slots, and re-starts the log file etc, so I chose the other solution for now.

I would prefer a variant which properly communicates back to the server that the WU was dumped, though.

A related feature request: https://github.com/FoldingAtHome/fah-issues/issues/1547

Although, reading the "sibling" bug report: https://github.com/FoldingAtHome/fah-issues/issues/1549

It seems that whichever way I currently dump, it's a problem - either it wrongly counts as a "faulty" WU (which it would become an hour later anyway, so it would still the better way if it was available as command to a running client), or the WU has to wait for it's timeout to be reassigned. A classic loose-loose situation

[UofM.MartinK]

I just noticed that the latest WU, project:16600 run:0 clone:1430 gen:235, allows more than 3 restarts, it did 8 so far and is about to complete the WU on my RX580!

I gather that this means a WU finished this way is still useful, after all?

I that can be confirmed, I will not dump 16600 anymore

[bruce]

If the WU is crashing because of an overclocked GPU, there's nothing FAH can do about it except to ask folks not to overclock. If it's crashing because of defective hardware, we can admonish you to RMA the hardware. If it's crashing because of a defect in the driver, we can ask you to convince the manufacturer to build good drivers.

If there's a defect in the FAHCore or in the construction of the WU, there's an ongoing project to collect the error reports returned from errors like yours and fix the associated problem(s). FAH does pay attention to those error reports and through them, science can do a better job in the future although I can't promise the fix will be rolled out soon enough to satisfy the folks making the reports.

[UofM.MartinK]

Bruce, I appreciate your very valuable contributions, but in this case, it's clear that many AMD models trash 16600 WUs - nothing to do with of overclocking or individual hardware issues, and not even the driver (version) might be at fault - it happens across all drivers and operating systems.

It's actually confirmed that there is something like an "incompatibility" of this project with many AMD models. According to SlinkyDolphinClock on discord the day before yesterday, it might have slipped Beta & Advanced testing because it was tested on an old FAH core - that's at least one hypothesis very actively discussed on slack with the lead developers, and some patch is in the works.

Back to business: My previous post was stating the observation that I now encountered at least one p16600 WU which internally has a significantly higher "Max number of attempts to resume from last checkpoint reached." (usually 3, but project:16600 run:0 clone:1430 gen:235 did resume 8 times and finally was completed). Other p16600 WUs after had the old internal restart limit of 3 again and thus were sent back "faulty" because they only made it to 15%, 32% or 42% before the "resumes" were used up.

If there's a defect in the FAHCore or in the construction of the WU, there's an ongoing project to collect the error reports returned from errors like yours and fix the associated problem(s). FAH does pay attention to those error reports and through them, science can do a better job in the future although I can't promise the fix will be rolled out soon enough to satisfy the folks making the reports.

Well, seems to apply in this case. But this is going on since August 3rd, so yes, not very satisfying - and "soon enough" is in the eye of the beholder

Now all I want to know is whether that was a deliberate change to let these "problematic" AMD GPU models complete p16600 WUs (perhaps because they serve some sort of purpose after all?) or if this was just a fluke and there is no value in processing them with an AMD card.

Another one here having issues with 16600 on an AMD GPU. I'm running a Sapphire Pulse RX 580 8 GB in my home theater PC, underclocked to RX 480 levels (-7%). Here's a tally of the WUs it's worked on in the last two weeks:

13421: 72 finished, 1 failed
13423: 13 finished, 0 failed
16600: 10 finished, 66 failed
16920: 1 finished, 0 failed

Here's the log of one that failed this afternoon:

Things I've tried so far over this last weekend - 18 failures since then:

• Update drivers from 20.7.2 to 20.8.2
  Undo my SoC undervolt (0.975v) - manually set to 1.1v, auto went to 1.25v, yikes!
  Set VDDP and VDDG voltages to auto - the former went down, the latter went up
  Stop CPU folding
  Update BIOS to latest version w/AGESA 1.0.0.6
  Run Memtest86 for 20+ hours - 0 errors

Until I looked in HFM's work unit history today and later saw this thread, I was strongly suspecting a hardware issue, hence most of the above troubleshooting steps.

My main PC's GTX 1080 Ti has had no issue processing 16600 WUs - 63 so far this month. It hasn't failed a WU since early July, even with it running slightly above 2 GHz .

[PantherX]

...Now all I want to know is whether that was a deliberate change to let these "problematic" AMD GPU models complete p16600 WUs (perhaps because they serve some sort of purpose after all?) or if this was just a fluke and there is no value in processing them with an AMD card.

Changes were made in FahCore_22 to fix the AMD issue and early testing showed promising results. Since there's a limited number of hardware that researchers have access to, they showed success. Beta testing didn't surface those issues and it only happened after being released to Full. Thus, reports like yours on this forum helps surface these issues since testing on every single GPU is not feasible so using the F@H community to identify and work together to solve it is really valuable

If the WU can fold successfully, that's counted towards science. If it can't the failures can still be seen by the researcher it isn't in vain.

Please note that I am aware that the researcher is aware of this issue on AMD GPUs and is allocating dedicated resources to further investigate this issue.

Project has been disabled on all AMD cards but Navi. Please let us know if you still receive new p16600 WU on AMD GPU

Ok so can I point out that we have one poster whose data is showing an issue with 16600 only and the other whose data is showing issues across the board including 16600 .. so there may be an issue with 16600 in some fashion but there also may be an issue with something in the setup of one on the rigs or a wider incompatibility with the current core for that rig? ... if it were simply 16600 it was failing on then yes look to the project but it isn't and so looking to the rig or core even if that is unpalatable may need to be considered - blaming one project for failures across the board seems odd?

[muziqaz]

Failure rate of 16600 is 32% which is very high

[Neil-B]

... and high rates of failure on 13421 (30 of 37 failed) and 13423 (7 of 8 failed) on the same rig ... that doesn't just feel like an issue with the 16600 project as far as that rig is concerned ... yes the 34 of 38 failures on 16600 may be down to an issue with the project but with the wider failures it feels like a rig issue or possibly an incompatible core to rig issue

[muziqaz]

This is not just this particular machine

[PantherX]

Regarding Projects 13421 and 13423, since they are highly experimental, they have a higher than normal failure rates. John is aware of the higher than normal failure rates and keeping a close eye on the failures. As long as data is successfully uploaded, that's still valuable work being done.

The next version of FahCore_22 (version 0.0.12 or higher) plans to take care of this by running some automated tests upon failure to ensure that these use cases which can't be reproduced in their labs or available hardware can be addressed.
