Mixed AMD/nVidia system - FINISHED_UNIT == UNKNOWN_ENUM??

Posted: Fri Mar 27, 2020 7:03 pm
by FalconFour
I've got a laptop with an Intel integrated GPU, nVidia discrete GPU, and an AMD GPU over Thunderbolt 3. I spent a good chunk of time last night trying to get the two to co-exist: saga and logs etc here: https://www.reddit.com/r/foldingathome/ ... _now_with/ - old thread revived due to Reddit missing its moderators.

After getting it working, I set off to bed. Woke up this morning to some VERY strange log messages. This is from the AMD slot:

For some reason it seems to be taking the FINISHED_UNIT return value and somehow, by inexplicable miracle of nonsense, interpreting that as UNKNOWN_ENUM and asking the core to start work again... which of course fails... but it doesn't do anything with the result. Nothing at all. It seems to just throw it all away, not even sending a result of failure or success to the server.

?Que?

Obligatory system info:

FWIW, it had previously been working (using AMD external GPU only), before fighting with getting the nVidia and AMD to both work under the same umbrella. Reinstalled the nVidia driver to get it up and running, then reinstalled the AMD driver second once nVidia was working. This is because AMD and nVidia seem to share an "opencl.dll" file in \windows\system32, which causes a conflict of who "owns" the OpenCL platform. But now that both seem to be working (both have high activity and crunch WUs), the only problem seems to be in how F@H handles it.

I guess that is the problem:
13:48:01:ERROR:WU01:FS01:Exception: 10002: Received short response, expected 512 bytes, got 0

It means the connection to upload server was truncated. Maybe a firewall is in place somehow interrupting the upload?

(On the other hand this seems also a bug in the FAHclient, as it does not retry the failed upload later again...)

Pretty sure that's a red herring - it happens all throughout the log and is most likely a log message from the WU downloader (which is running as the WU nears completion), not the uploader. There's definitely no firewall at play here.

CPU slot finished up just fine seconds ago:

Nothing at all. It seems to just throw it all away, not even sending a result of failure or success to the server.
The FINISHED_UNIT is the red herring, the real cause is shown in the next two lines:

The client is reporting a Windows error code passed to it as the folding core crashed. This is during a post completion phase where the WU is being packed up with some essential other files to be sent back to the WS. The log shows those files being read just before the crash.

Someone with a deeper understanding of Windows error codes would have to look at this, I just recognize it for being that.

Depending on what exact files are left in the directory after such a crash, the client will attempt to restart the WU. It may start over at the very beginning, at the last checkpoint, or dump it as a corrupted WU.
