CPU still works fine.

Code: Select all
04:52:41:WU02:FS01:0x21:ERROR:exception: Error downloading array interactionCount: clEnqueueReadBuffer (-5)

This error in your log for the GPU slot probably means you recently updated to one of the version 375 drivers from nVidia. They apparently managed to break part of the OpenCL implementation, these drivers do not work with Core_21 projects. The latest version of the driver reported to work is 373.06.

A blog message about this has been posted by PG, there is a topic here following the issue.

Re: GPU folding fails -- clEnqueueReadBuffer

Postby RABishop » Tue Dec 06, 2016 9:47 am

Early yesterday I saw my point totals dropping, so I checked each of my machines. The machine I call #2 had a problem, which I was hoping would workout; but it hasn't yet. There's always been something odd about that machine. There is an X99 mobo in it, and a 5930k processor, along with 3 NVIDIA graphics cards. I noticed a LONG time ago that the cards were being misidentified by the version of Mint 17.3 that I am running on that system. In the top slot, I have a 980Ti. In the middle slot, I have a 1080; and in the bottom slot, I have a 1070. I am NOT using that machine right now to report on this problem. That machine also has graphics issues which I have not been able to solve. So I have to do this from another machine. The point is that the newest of NVIDIA cards, the 1080s and 1070s aren't even identified, in LINUX, with any more than a code designation.

On the machine in question, it says I have a 980TI, in the top slot. It says I have an 1080 in the mid-slot. This is true, although they might be reversed in order from top to bottom. Either way it is, the fact that I have a 1080 in the middle is undeniable. But, what I have in the bottom slot is NOT a 1080, but a 1070. And I now suspect that a 1080 job has been dropped into that 1070, which doesn't have enough cuda cores to process the job. So, since early yesterday, that slot has been saying it's going to take 21.33 days, or something like that, to finish. It just keeps saying for a while that it is running, then reverts AGAIN to a non running state.

As I said, that system has graphical interface problems. Things like boxes sometimes show up in it (like the box I'm typing in, NOW) only partially formed, or with no borders at all. I have no idea why the 1070, in the bottom slot, was ever identified as a 1080. I'm getting graphics from the 980TI, in the top slot. But those graphics are so poor, it's nearly impossible to use the system in question for communications purposes. I know this is weird, but my memory isn't so perfect that I can go to the defective system, and memorize everything about it, in order to use it, to communicate here.

OK, well it seems there have been no replies to this. I knew it was a complicated mess when I tried to describe the problem. I guess the best thing I can do is just shut the whole thing down after uninstalling FAH, then try a reinstall, going card-by-card, and hope the machine will correctly recognize the 1070 card as a 1070 and not a 1080.

Many, many failed GPU jobs

Postby RABishop » Tue Jan 31, 2017 10:52 pm

I just checked one of my machines (this one) after having made sure, about a week ago that it was functioning properly over a couple of hours, precisely because of many previously failed GPU jobs, on this machine. Three GPUs, not in use due to failed jobs. Who knows how stinking long that was going on! ON the previous occasion, I uninstalled and reinstalled the Client using the terminal. I just did it again this time, and I managed to get 2 out of the 3 GPUs to install correctly. Although the 3rd seems to install, now it gets nothing but failed jobs again. I uninstall and reinjstall that card, and the Client just keeps giving me back the same job, over and over. I just looked at the Control Window. The last thing I did was uninstall the Card, so I can't say now what job and server might be involved. I DID copy the log file, perhaps (or not) before I uninstalled the card.

Here is that information:

It looks as though I had uninstalled the 3rd GPU before copying the log. I'm not going to make any major changes until after I hear from someone that I ought to do so. At least the thing is making contributions with two of three cards. I'm using Mint 17,3 Cinnamon as an OS. System info recognizes all three cards, and NVIDIA X Server recognizes and allows me to control each of the cards' behavior. What I CAN'T understand is why the Client would continue to try feeding a jobs that ALWAYS is, inevitably, going to fail back to the same slot. And, even less, do I have any clue as to how to stop this junk without doing a complete uninstall and reinstall. Maybe someone can help me with that.

Your post doesn't tell us which drivers are in use, nor do they tell us which projects are failing. Using FAHClient, view the log. Press "refresh" and scroll back to the beginning. Post the section before a segment like the part you just posted. Then select the slot associated with the failed WUs (slot 3?) and paste enough of that log here so we can see what's happening.

GPU folding fails - clEnqueueReadBuffer (-5)

Postby foldinghomealone » Wed Feb 01, 2017 7:28 pm

Hi there,

I'm folding since Oct. 2016 but new to this forum. For a few weeks now, approx. 10-15% of my WUs fail. Before that it basically didn't happen.
I'm using FAH 7.4.4 on Win10 64bit and a GTX 1070 with driver 372.70.

This is the log from my last WU from today morning.

Does it mean that the WU is damaged or is something wrong with my system?

Losing 10% of WUs is not really encouraging. Thank you for your help.

Re: GPU folding fails - clEnqueueReadBuffer (-5)

Postby bruce » Thu Feb 02, 2017 1:26 am

There has been an update to FAHCore_21 which fixes this problem. The new version (0.0.18 or later) is in the process of being pushed out automatically. Many projects have been adjusted to require the new version but some still accept the old version 0.0.17.

I'll speak to the owner of project:10496.

You can fix this manually or you can wait to be assigned a project that has been updated.

Unfortunately the same happened with version 0.0.18 just now:

Unfortunately I don't know what to tell you.

I did check, and you got partial credit for your efforts. It was reassigned and somebody else who completed it. I have no ideal what might be different about their system.

Then it seem (at least for me) that my system is somehow not stable.
Ok, thanks for your answer.

I think clEnqueueReadBuffer (-5) is an CL_OUT_OF_RESOURCES error. Is it possible that other activity on the system caused all memory to be exhausted?

I don't think so, right now, the GPU is used only for folding purposes.
I use CPU and iGPU for internet browsing from time to time.

Unfortunately, clEnqueueReadBuffer (-5) error happening during the processing of a WU is a sign of an error with hardware. This error usually happen when GPU crashes, and that the OS has reset the drivers to recover the issue. Usually, after this issue, the GPU will stay in safe mode (reduced clocks and voltages) until you reboot your system.

Does it happen while you're using your machine, or also when nothing but FAH is running ?

I see also from you log that you got some spurious Bad State, which could also be the sign of an unstable GPU ...

Check if everything is OK with your GPU (are fan spinning fine ?), monitor temperatures, voltages and clocks with GPUZ ...

You can also try to run FurMark on the GPU to stresstest it.
