Re: OpenPandemics GPU Beta Test - March 5 2021 [ Issues Thread ]

G'day uplinger, thanks for the update/switching on validator. All of my work was marked as valid :)

Looking forward to the next run when it's ready.

When the application goes into production will we be able to choose to opt out of GPU work as soon as it's available or will the only way to do this be not to have this project ticked? I am aware that I could disable GPU in my preferences but as I understand this would stop us from receiving any beta work

I opted out of NVIDIA tasks because it threw too many errors, still got Intel jobs.

Re: OpenPandemics GPU Beta Test - March 5 2021 [ Issues Thread ]

@Uplinger, I am aware you have several things on the go at present, curious to know if you know when you will be turning the validator on from the run on 3/5/21 and 3/721 (dates written same as in tasks sent column).


Hey Speedy,

I'm capturing some stats right now from the beta and collect a list of cards that have issues. Also, I have adjusted the estimated computational power needed to help with points on the next beta test. Which does not have an ETA at the moment as we are still working towards getting results back in Alpha test on them.

Long story short: I plan on turning it on today.

Thanks,
-Uplinger
Well, looks like the validator run, but to grant all the validated WUs a mere 0.4 credits across the board is certainly not helping to make this very attractive to all those GPU enthusiasts... ;-)

Re: OpenPandemics GPU Beta Test - March 5 2021 [ Issues Thread ]

Could I throw out a suggestion for consideration. I'm not entirely sure how difficult it would be to do, but would it be possible to create a GPU validation WU that would actually test in turn each function of Open CL v1, v1.1, and v1.2 and then in the output report print the result of each function test?

Just because the card is reporting that it is capable of CL 1.2 after driver updates doesn't necessarily mean the underlying silicon chips are. My car has a speedo that goes up to about 160mph, but but nothing else on the car will.

In BOINC Manager Tools/Event Log it should show what the card is capable of, though you may have to reboot to see it. And what BOINC thinks it sees is what you get I believe.

Re: OpenPandemics GPU Beta Test - March 5 2021 [ Issues Thread ]

Just wanted to say, that some WUs seemed to be stuck on my end as well. The timer continued counting up, but GPU util was at 0 percent. Suspending and unspuspending did the trick most of the time if a WU ever got stuck. Just curious and a bit annoying that I just found out after a couple hours of running beta tasks and some tasks already recorded ~ 2h runtime on a 1660 Super, just to apparently jump back to the last checkpoint and then finish within minutes.

Re: OpenPandemics GPU Beta Test - March 5 2021 [ Issues Thread ]

Hu:
Thank you to all who contributed to the issue with my Geforce 660M V.C. in my Alienware laptop.
Here's the output from rebooting Bonic:
2021-03-10 4:12:46 PM | | CUDA: NVIDIA GPU 0: GeForce GTX 660M (driver version 425.31, CUDA version 10.1, compute capability 3.0, 2048MB, 1691MB available, 730 GFLOPS peak)
2021-03-10 4:12:46 PM | | OpenCL: NVIDIA GPU 0: GeForce GTX 660M (driver version 425.31, device version OpenCL 1.2 CUDA, 2048MB, 1691MB available, 730 GFLOPS peak)
2021-03-10 4:12:46 PM | | OpenCL: Intel GPU 0: Intel(R) HD Graphics 4000 (driver version 10.18.10.5161, device version OpenCL 1.2, 1400MB, 1400MB available, 166 GFLOPS peak)
2021-03-10 4:12:46 PM | | OpenCL CPU: Intel(R) Core(TM) i7-3740QM CPU @ 2.70GHz (OpenCL driver vendor: Intel(R) Corporation, driver version 3.0.1.10891, device version OpenCL 1.2 (Build 76427))

When I checked TechPower Up GPU-Z and placed my cursor over OpenCL it indicates ver. 1.2 CUDA

Yet the GPU fails the Beta tests. So go figure.............

All except 1 of my Beta tasks validated now.

This one, still waiting for a wingman to finish it (or fail):

Re: OpenPandemics GPU Beta Test - March 5 2021 [ Issues Thread ]

Good evening,

As for the question on our GPU cards to test, it is very limited but they mostly mid range cards. We don't have any of the cards that are causing issues on the grid. However, as mentioned before we do have a code fix to the opencl code that may fix the double precision issue. I'm guessing that some of these cards that are failing don't have double precision capabilities and aren't throwing an error to indicate it. The researchers found 2 locations in the code that might leave ambiguity in the definition of the float.

We have received the first production batches from the researchers a few hours ago and are working to get them downloaded, built, and loaded using all the automation steps on the servers to be ready for full launch. We will be testing these on alpha first and then moving them to beta. As a plus, one of the main developers of AutoDock has started to explore the points issue :)

Another issue that was diagnosed with the latest beta results is that the validator did have a bug in it that was causing some invalid results being marked as valid. This has been updated and will be tested in the next Beta test as well.

I'm sure I'm forgetting something, but again, thank you for all your help!

Thanks,
-Uplinger
