Ok, I'll forward this to the devs as this really looks strange.

Thanks for reporting this,

I just got a note from Bruce Allen, pointing out that the new CUDA app versions will perform a check of CUDA memory resources before starting, and if there isn't enough on-board memory available, the app start will be retried a couple of minutes later (earlier version would just error out in this situation).

So theoretically this could be the case. I wonder whether there is anything to this effect in the stderr.txt file (where the logging messages are started) in the respective slot directory (one of the /Library/Application\ Support/BOINC\ Data/slots/ directories).

So, is the ABP1 task never started at all (state "ready to start") or is it started but doesn't progress ? (state "waiting to run" etc) ?

You meant ABP2...?

They never started. It just says "Ready to start". They were never in a state of "Waiting to run". No error messages from BOINC. The ABP2 app was never shown active on Activity Monitor. The GT120 was only shown using 2 - 5% graphics usage from Hardware Monitor driving a 24-inch display.

Hi,
Thanks for the update.

Tasks are "ready to start" and there are no others CUDA apps running.
No entry for Einstein ABP2 in slots directories.
It looks like STSP 5.07 application units (ABP2) are never handled by the scheduler.
During that time, CPU units (S5R6) are successfully computed.

Did you try a reboot to clear graphics memory?

Can you otherwise reduce GPU menory usage (desktop resolution...)?

Hi,
Yes, computer rebooted.
Even with very low resolution (640*480) and all others projects suspended, no ABP2 unit started.
In slots directories, no trace of attempt to start ABP2 unit.
What is the amount of Graphical memory needed by 5.07 application? (GeForce 8800GT is a 512MB card)

Hi all,

EDIT: it requires around 430 MB free graphics mem or some such. So it will depend on the video mode whether this will work on a 512 MB board.

Anyway, let's try to get a bit more data on this one.

If you put the following text into a file cc_config.xml in the BOINC working directory (/Library/Application Support Data/BOINC on Macs) and restart BOINC. There should be some more log messages explaining hopefully why boinc does what it does (or fails to do).

EDIT: corrected type:

Hi Bikeman, I got this error

Blimy! The whole kitchen sink.....

You'll get masses of output with all of those set. Don't run it like that for more than ten minutes, then disable all except the first three by changing the 1 to 0 (those are ones and zeros). Then restart BOINC, and take stdoutdae.txt away into a dark corner to see if you can find a smoking gun.

If you do find something, just re-enable the single debug log that showed it, and take another 10-minutes worth (or until it shows again), and just post the essentiial snippet here. We can always ask for a longer run if the first proves inconclusive.

And if all else fails, there are even more logging flags we can show you to try - the client configuration page hasn't been updated with all the new v6.10 goodies.
