Folding client fails on GPU [Handbrake conflict?]

[Euphonium]

Hello.

I run FAH on my GPU only, usually when I'm running Handbrake on my CPU. Recently it has started to fail repeatedly somewhere between 3% and 10% of the way through a work unit, and sometimes crash altogether.
I have tried reinstalling FAH from scratch and updating my graphics drivers to no avail. CoreTemp and GPU-Z tell me that I don't have any overheating issues. I have tried running FAH on my GPU with the PC otherwise idle, and get the same results.
I've searched the forums, but can't find anything that seems to apply. My search-fu is weak, so I apologise if I've missed an obvious answer.

My system:
i7-3770k, 16GB RAM, nVidia GT980Ti, running Windows 7 Ultimate 64-bit

I've attached the logfile from my latest run. I've read through it, but don't understand what it's telling me.
Can anyone offer a solution, or a suggestion for further investigation, please?

I don't see any indication that the WU runs for more than a few minutes before getting an unknown error. ... nothing like 10% in that run.

THe first time the WU started, it got an "Unknown Enum Error" about 9 seconds after starting leaving no checkpoint.
The second time, it ran for slightly more than 2 minutes before crashing.
The third time, it ran for about 3 minutes.
The fourth time, it ran for almost 4 minutes.
FAH passed it's limit for the number of unsuccessful retries and aborted the WU.

It's not clear what's happening, but it does look like your GPU is unstable.

Likely possibilities:
* The GPU may be overheating. Check the fans and monitor its temperature.
* The GPU may be overclocked too munch.
* There may be a problem with the drivers. Which driver version are you running?

Knowing what other WUs you've tried and whether you got more or less the same results would help. Previous log files can be found in
C:/Users/Euphonium/AppData/Roaming/FAHClient/logs listed by date and time.

That run failed particularly quickly. I've seen runs make it to 8%+ before failing

My GPU is not overclocked.
The manufactured-supplied monitoring software and GPU-Z both show it holding steady at 70'C
Diver versions:
I originally noticed this problem under 358, I don't know the subversion.
I updated to 385.41 but that hasn't made a difference.

Do you want full logs, or are there key parts I can cut from them rather than provide a huge wall of text? I've got about 1.3MB of logs from the past week.

[bruce]

The most useful information would be the list of failed WU, though I'm not sure what that might show. The lines will look like this:

...Project: 9415 (Run 1255, Clone 1, Gen 120)

[Euphonium]

I've done a bit more experimenting, and the problem appears to be linked to me running Handbrake at the same time, even though AFAIK Handbrake doesn't use the GPU for encoding.
I ran the FAH client with Handbrake loaded but not encoding, and the WU completed successful with no error as per the log below:

I let the FAH client download a new WU, then started Handbrake. The log shows an immediate unknown error, and the client reaching 7% a series of unknown errors forced it to abort:

My Handbrake client is v1.0.7 (2017040900) - 64bit
I noticed that when Handbrake was running, my GPU load changed from a steady ~100% to jumping rapidly between ~100% and ~40%
I can try to capture a screenshot of my GPU monitor showing the change in behaviour if that would be useful.

I'll have a dig through the logs later this evening if you think a list of WUs that gave errors will be useful

[bruce]

AFAIK Handbrake doesn't use the GPU for encoding.

With folding on your GPU suspended, doesn't handbrake cause 100% GPU usage?

GPUs have [n]none{/u] of the essential process management routines found in your OS that organize the workload for your CPUs. Thus it's not surprising that one of those two apps that are contending for the use of your GPU might see a problem. [I'm not pointing fingers specifically at either FAHCore_21 or Handbrake, but at the unknown conflict that you're reporting]

I do see other reports that handbrake conflicts with other programs, which suggests it might be at fault ... such as
https://www.tenforums.com/bsod-crashes- ... flict.html

I'll pass this problem on to FAH's technical people who might be able to diagnose it.

[Euphonium]

With folding paused, Handbrake places no load on the GPU

Thank you for passing this on. I'm not blaming either piece of software either. In the past I've run both of them together without noticing any problems. Most of the 300 or so WU I've processed have been done when my PC was doing overnight encode with Handbrake.

edit: Added screenshot showing CPU & GPU usage with Handbrake running and FAH paused

Does handbrake have any advanced settings that might enable/disable the use of a GPU for encoding?

I see some reports mentioning a conflict with certain Linux library routines. I have no idea if that might also be true on Windows.

Since it sometimes works and sometimes doesn't perhaps you can evaluate whether the failures are related to:
> The particular video encoding standard
> Particular WUs from FAH.
Hopefully that might help guide the debugging of the conflict.

I'm going to assume that you have an igpu which can be used to display video if you don't happen to have a GPU -- AND that you're wiling to help dig into this problem. (Don't feel bad if you choose to say no, since debugging such a problem can lead to unexpected issues that can take time to resolve.)

If you remove or disable your GPU entirely, you should be able to get Windows to use the iGPU -- though you may need to change settings in your BIOS. Will handbrake still run, and if so at essentially the same speed? When you do that, FAH will discard any WU that has been downloaded to be processed by the GPU, so be sure to FINISH the active GPU WU. (Right-click on the GPU slot in FAHControl)

[Euphonium]

I'm willing to have a look and see what I can find out.

I run four monitors, three 1080p monitors off my GTX980Ti and one 900p off my iGPU. I'll have a look at seeing if I can disable my GTX980 without messing things up too much. I'm not willing to physically remove it at the moment.

I have recently updated Handbrake and switched from encoding with x264 to using x265.
I cannot find anything in Handbrake's settings that mentions using my GPU, but my GPU monitoring software says my GPU usage is 0% when Handbrake is running.

Once my current encoding cue is empty, I'll find a smaller file and try using x264 and x265 to see if the problem appears to be link to a specific setting in Handbrake.

[foldy]

If the x265 encoder has a setting using CUDA or OpenCL that would be in conflict with FAH while QuickSync is fine.

[Euphonium]

As far as I can tell, Handbrake does not support openCL or CUDA.
I can't find any mention of CUDA support in the documentation, and openCLis only available as an experimental option for scaling - I'm not using it.

[Euphonium]

I've done a couple of tests with my hardware unchanged.

A manual log of what Handbrake was doing and how that affected F@H:

Found this screenshot, you want to disable DXVA and enable quicksync:

The "disable quicksync decoding" box is already unchecked - that's the default setting for Handbrake v1.0.7
I use x265 for encoding because quicksync gives noticeably poorer quality output.
