Bad Work Unit - need good stress test?

KA1J · Post by **KA1J** » Sat May 23, 2020 9:23 pm

I've run into another bad work unit seen below at 16:33. The first bad work unit/crash was, I was told, picked up by another cruncher and was completed successfully.

I have tried to stress test the GPU and all my attempts have been successful. The two tests I have tried are FAHBench using OpenCL, single precision, WU is DHFR, NaN disabled. tested 30 minutes with no drama.
Results: Score 179.037 & 23558 atoms.

I ran Unigine Heaven with the below results:

I do find when I run benchmarks, it's a few degrees C less than when I run F@H and since I have no trouble with benchmarking and the tests not having errors, I'm stumped. Is there a test that challenges the GPU as much as F@H that will tell me if any errors are coming up?

Reviewing with search I have found reference in this forum to deal with this error, to changing: configure > Slots > GPU > Edit OpenCL-index from -1 to 1. Before I make that change, I'm asking here before I do that.

Also, a better F@H compatible stress test?

Thanks

Please note that we need to see the entire section of the log file just before the failure, during the failure and after the failure. Unfortunately, this line doesn't tell me what WU it was:
16:36:20:WARNING:WU00:FS00:FahCore returned: BAD_WORK_UNIT (114 = 0x72)

Generally speaking, most stress test and benchmarking applications are less stressful than F@H. Those software focus on rendering aspects of the GPU while folding focuses on the compute aspects of the GPU. Hence, it is tough to measure the stability of a GPU using third party applications. The current version of FAHBench doesn't support FahCore_22 but there are plans to get to it once a new version of FAHCore_22 is released (no ETA).

BTW, can you also please post the first 100 lines of the log file which will contain the details of your system and the client configuration?

That's all that's left of the info when the bad work unit appeared, I can't post any more from that one. F@H isn't delivering WU's & with that, I just closed down F@H, restarted & here's the log.

Unfortunate there's nothing easily available to properly challenge the computational end of the GPU as regards F@H. Thanks for the info.

FAH officially does not support overclocking. Maybe that's just another way of saying the FAHCore for GPUs is the de-facto benchmark for GPUs

... and all those other benchmarks are less stressful than FAH so don't depend on them for Stream Computing. (Yes, benchmarking video page rates is something different.)

If you've looking for other WUs that reported errors, you can find a number of previous log files in the "logs" subdirectory of FAH's data directory.

Heh, short of doing a Macrium backup to a new drive & recloning that backup & then running F@H freshly with the same WU & operating conditions (with internet access off) & then using F@H as a valid testing benchmark, F@H would be a tough one to use as a benchmark.

For me, I'm sure for you & most of us, this is important for science & especially defeating Covid which is killing thousands worldwide every day. I want to be able to do the maximum number of WUs possible and I don't like corrupted WUs, if that happened because of my system. If my system has good integrity and the WU crashes, so be it, that's beyond my control.

As I read of so many at F@H who are overclocking to get more WU's done, it seems like a test available to fine-tune a GPU with the current core would be a proper software for quality control.

Post by **bruce** » Sun May 24, 2020 2:45 am

If FAH could block assignments to overclocked machines, they'd probably do it. Unfortunately when a machine asks for a new assignment, it doesn't say "...and I'm not overclocked" so we have to give them an assignment which may run without error on a cool day and may fail on a hot day (or whatever). FAH's design goal is to make use of ALL of the available resources you choose to donate ... and that has to be based on hardware that meets the original hardware design goals -- no more, no less.

On the other hand, when new code is being developed, it's supposed to find all software QC problems during beta testing. Unfortunately the beta testing team don't happen to have representatives of all OSs and all GPUs and all other client variations so it's difficult to define how long beta testing needs to run to catch all the potential issues.

Because of the urgency of the MoonShot project, that "supposed to" was relaxed because there were many, many clients that were not well represented during beta testing. To find those other issues, a few projects like 134xx temporarily slipped through the "beta testing only" firewall.

Sorry.
