Message 1720390 - Posted: 30 Aug 2015, 20:55:59 UTC
Last modified: 30 Aug 2015, 21:00:08 UTC

Finally upgraded the BIOS so I was able to install 2X750TI in this computer: 7226971. I started it up and upgraded my optimized app. When the update of the WUs happened I got one AP along with this message: Bill8PC [error] Missing coprocessor for task ap_26ap11ac_B4_P0_00032_20150830_15154.wu_1; aborting

What do I need to do to prevent this from happening in the future?

/edit seems I got 3 AP tasks and they all failed with Aborted by User. I did nothing to cause that that I know of and I had not been running APs on this computer before this as I was having problems with the video cards that were in it. /edit

I'd suggest trying the same version video driver as you've got on your other system (which I assume is working OK).

What Grant said with the additional suggestion you choose "Clean Install" under "Custom" in the NVIDIA driver installation package.

Thanks, but I did that already. What seems to be happening is that OpenCL is not loading for some reason. Error states: Bill8PC8/31/2015 17:19:17 App version needs OpenCL but GPU doesn't support it. How can that be as I am running OpenCL on the other two identical cards.

I think the two errors are related. I just upgraded this computers BIOS as the previous BIOS told me it could not run these video cards. The upgrade of the BIOS worked like a charm. I suppose I could do the upgrade again and see if anything changes.

When in doubt, post the first 40-50 lines of the BOINC Start Up messages from the Event Log (CTRL+SHIFT+E).

Are you running open-cl CPU tasks?

In your log is no reference even for that.

EDIT: never mind--i was looking at the the wrong thing.

It's only temporary until you load a driver. When no specific driver has been loaded, a standard VGA driver is used by the OS until you install one.

And at least in Windows 8 and probably 10 as well, that's at a reasonable 1024x768, much better than the previous 640x480 (XP) and 800x600 (7).

OK I will have to do that in the computer room as I normally work remotely to the computer.
I will give it a try after I get something to eat.

Ah, in that case it would technically be XGA instead of VGA.

maybe i should backtrack on that. windows 10 has a tendency to want to install its own drivers over anything you've put on before. there might be some fix for that, but there's always the fear that some future update would break the fix. i haven't used nvidia in a while, so i don't know what the appropriate driver is for a 750Ti under windows 10.

in my case i feel that somewhere along the line ati broke its drivers with regard to running multiple wu per gpu (espcially in a multi-gpu setup) so i decided that last year's catalyst 14.4 driver was worth a shot. rather than try to force old drivers on windows 10, i wiped out two computers and put them back on windows 8.1

What is this about?

"43 Einstein@Home 8/31/2015 17:19:17 Found app_config.xml
44 Einstein@Home 8/31/2015 17:19:17 Missing <app_config> in app_config.xml
45 SETI@home 8/31/2015 17:19:17 Found app_config.xml "

What "<app_config>" is missing?

In other words, some line in the app_config is messed-up and the line should be "<app_config>" itself, or you might have gotten an indent wrong.

This probably has NOTHING to do with your problem, but it's worth dealing-with.

Second, BOINC is obviously "seeing" the card. Obviously OpenCL IS supported by the card.

Solution: Reinstall the drivers to a new subdirectory and use the "clean install" option under "custom" in the installation package.

If it were ME, I'd uninstall the old drivers first, run Driver Sweeper, run CCleaner's registry cleaner, reboot and wait half-an-hour for Windows to load a compatible driver, then reinstall the drivers from NVIDIA's website into a new subdirectory using the "Custom" option of "Clean Install" during the installation.

Then before I believed anything I read, I'd reboot.

And then, because I'm me, I'd re-re-rerun CCleaner and get rid of all of the installation remnants.

...and compute happily ever after.

HOWEVER - I have an ASRock Extreme 3 motherboard and two dissimilar cards on it (a 970 and a 560Ti) and it refused, no matter what I did, to load both cards. I had to remove one card, load the driver. Then put that card back, remove the other card and load the driver. THEN, bizarrely, I had to reboot using the output from the 560Ti which was in the second slot in order to make the machine see it (it wasn't showing up in device manager). Once I did all that everything worked and from that point forward I could boot the computer with either card connected to the monitor and both cards would work.

Yes, it took a very long time to go through all of that to get both cards to work and took even longer to get to the point of trying the above in desperation.

I'd go through all this stuff for you if I were there.

Want me to remote-in? :-)

Nvidia did have an issue when win 10 first came out, but they fixed that pretty rapidly. It looks as though you are using the MS supplid drivers which are cut down from the Nvidia ones, MS remove chunks of the "unwanted" computation drivers (well unwanted by MS). You will have to get the Nvidia supplied drivers, from the Nvidia site and do a clean install. During which you will loose the display, but once the installation is complete you will have it back, but you may have to rest the resolution manually. Before getting the new driver turn off automatic driver updates as windows will attempt to install its own driver at some future time.

I edited out a bit of your post....but thanks for the offer of remote-in-ing but I think I have it.

YOU WERE RIGHT.......remnants of OLD DRIVERS were the problem. I ran Drive Sweeper, now called Display Driver Uninstaller, and the program did its job.
I rebooted into basic display(I did not check the aspect) and downloaded the latest NVIDIA driver for WIN10. Upon Reboot BOINC is running just fine.

Thank you, Thank you very much.

P.S. the Einstein app_conifg.xml error was just that there was one with incorrect data in it. Deleted the file and the error is gone.
PP.SS. never trusted CCleaner as long time ago I ran it and it made my system completely unusable. DDU has its own registry cleaner built in for what it is dealing with and as you can see that was enough.

Rob, you just have caught a look at my drivers during some of my changes. I have not had a problem with Windows installing drivers as this is a Pro version from the beginning and I was able to control that function from the start.
