I'm new to this. Yesterday I finished my first long WU. Since then whenever I force an update I get no work from GPUGRID and an event log entry "5/3/2013 8:47:00 AM | GPUGRID | Not requesting tasks: don't need".
What do I have set wrong? I have the resource share set at 100 (my other two projects are set at 25 and 50). I have all tasks selected except Beta. And the other two projects are humming along as normal. Nothing is "suspended".
Thanks,
Win

Hi, fellow newbie:
Your 'maximum work buffer' in the BOINC - Preferences may be set too low. My buffer minimum and maximum are 0.10 days and 0.30 days respectively. This appears to work with the WCG SN2S tasks I also process.
Regards,
John |

Do you mean these BOINC settings? This is what I have:
Maintain enough tasks to keep busy for at least
(max 10 days). 0.5 days
... and up to an additional 1 days
I can't find any other setting "maximum work buffer".
It did take over 2 calendar days to finish the one wu I've done (my PC does not run 24/7). Should adjust these higher?

Just the opposite; reduce the cache to 0.01 and 0.01.
Your GeForce GTX650Ti is quite capable of completing a task inside 24h, if you let it run non-stop. If on the other hand you have configured Boinc so that GPU tasks don't run when you are using the system, and you switch it off a lot, then you will struggle to complete a task inside a day.

IF he uses the pc the 25% setting for the cpu usage could be getting in the way too. |

Thanks for the feedback. The only problem I was concerned about was not getting any new WUs, and that somehow resolved itself without any parameter change.
I can finish a wu in about 12 hours runtime if I temporarily suspend the other two projects I'm working.
I haven't tried all the various app_config suggestions, but since I have just one GPU with 1GB of memory I run just one GRID wu. (I've seen that one wu consume over 700MB of memory at times, so two would be problematic.) I have my app_config set for 1GPU and 1CPU. I've found that anything less than 1CPU results in lower GPU utilization. Typically the GPU utilization hovers around 90% with some spikes and dips.
Thanks again for the help.
