I just noticed my sieving box has gone from around 8 minutes to roughly 26 minutes doing cullen/woodall sieve. have they gotten bigger or has my computer glitched? i run it 24/7 dedicated. just wondering when i get time ill reboot and see if it changes back to normal.
Thanks

I have been seeing my CW CUDA Sieve WU silently dying and then ending in maximum work time elapsed error message if I don't cache them in time. The CPU part of the application keeps running but no further progress is made on the GPU and the progress bar stops. If I suspend the WU and the unsuspend the WU resumes at the last checkpoint some times losing 12+ hours of fake crunch time.
http://www.primegrid.com/result.php?resultid=375541639 This one I did not catch in time before the clock ran out.
My system in a Mac Mini 2010 model with an Nvidia 320M GPU OS X 10.6.8 8GB ram.
The error message when I restart the WU is something about missing shared memory or something like that and a warning to watch and see if it keeps happening. I looked for the exact wording but is not in the message log since the last time I restarted BOINC in the last 5 days since I last restarted boinc. It happens at least once a week.

Look at here: http://www.primegrid.com/forum_thread.php?id=2557#23939

This error occured a time ago. Maybe the app also need some optimization.

This is what the PrimeGrid errors look like. I just got the same set of errors in Collatz. I'm copying the Collatz message here for informational purposes and will also post them in Collatz.

Thu Apr 26 19:04:39 2012 | Collatz Conjecture | Task collatz_2375033642863672666472_824633720832_1: no shared memory segment
Thu Apr 26 19:04:39 2012 | Collatz Conjecture | Task collatz_2375033642863672666472_824633720832_1 exited with zero status but no 'finished' file
Thu Apr 26 19:04:39 2012 | Collatz Conjecture | If this happens repeatedly you may need to reset the project.

I think it may represent the GPU ran out of memory and silently stopped working until it was told to suspend and then BOINC notices it has stopped and posts the error.
