Driver Problem?
Try 497.09 released Dec 1st ....
Maybe that is the solution!
Please remember that O3AS WUs usually need a GPU with more than 2GB but less than 4GB.
Not always - depends on the WU.
Have a nice day
Thanks for the info on that

Thanks for the info on that NVIDIA update; I'd missed that. Unfortunately, it doesn't seem to have helped. Even after installing the 1Dec21 drivers and rebooting (multiple times now), Einstein isn't working. Same error message
(from https://einsteinathome.org/task/1198531885).
I don't think it's lack of memory; if it was I'd expect the error message to be the one about: Can't allocate memory. But maybe something's changed.
Milkyway does work sometimes after a reboot. Not always.
Have you tried uninstalling

Have you tried uninstalling the graphics driver completely and rebooting?

When graphics driver problems crop up, it is usually best to clean them out completely with the DDU uninstaller to get rid of any lingering remnants that will continue to foul up new reinstallations.

Your graphics card only has 2gb of memory on it don't the O3AS tasks require a gpu with at least 4gb?

Good info to know. I was unaware that a program existed to wipe clean the video driver for a fresh install of a new one. Does this also work for Linux? The website doesn't say anything about Linux, so I expect not.

No, the DDU uninstaller is for Windows only. For Linux you need to use apt purge.

Many times they used to (earlier this year)... but not anymore. Nvidia 2GB works well these days.

Thanks that should help alot of people, and the constant questions as to why it didn't work as well.
As a followup, NVIDIA did

As a followup, NVIDIA did release an update to their driver (on 20Dec21, but I just learned about it today). Probably doesn't really fix the problem, but I did learn something.
I did a clean install with the new driver, uninstalling the old one first (didn't use the Wagnard uninstaller yet, just NVIDIA's own installer software). Then changed the BOINC client computing preferences so that I wouldn't suddenly get 24 Einstein jobs that all fail immediately, causing Einstein to not send any more workunits for any configuration for a day.
The first couple of NVIDIA tasks were GRPB, and they actually finished without problems. (Haven't got credit yet, but I'm hopeful, once it's validated.) However, then I got a GWO3AS task, which got a computation error in about 3 minutes, similar to previous experiences. However, at least I see now that the error was a memory allocation error:
(from https://einsteinathome.org/task/1212200757)
After that, all jobs trying to use the NVIDIA driver failed, not just Einstein jobs, but anything else as well, until I rebooted. The other GWO3AS jobs that tried to run had a different error, not memory allocation:
So I currently suspect that 1) I don't have enough memory to run (some) GWO3AS jobs, but 2) the bad part is that when this happens, it leave the laptop in a bad state, essentially unusable for any job. So I'm holding off on running Einstein jobs on NVIDIA for now (Still running on the Intel driver, though). Might exclude the GW03AS in the future, as one possible alternative.
