I disconnected and reconnected to the project ant it downloaded a new work unit I will have to see if it continues to download new ones after this one is finished. | |

It did the same thing! Downloaded one and when finished it stopped and did not get more work! Would really like to have this working if anyone is actually monitoring this! | |

If the drivers installed properly Boinc may be starting before the drivers are ready. Add a delay or restart boinc from a terminal. | |

That's a CUDA 6.0 driver, but it should suffice for now. | |

Not downloading task, but in profile one in progress.The first thing is not the consequence of the second. How delete it from prof, to get a new task?You can't delete it, but it doesn't matter, as the reason for not downloading new work is that there is no work to download at the moment. Wait to deadline 12 jan?Yes. If there will be work available in the meantime, your PC will download new work. | |

the deadline 2016-Jan-12 is over and the problem of getting no new tasks ist still not solved!!!Everyone else is getting work, so this problem is *not* the project's fault. Fr 29 Jan 2016 21:02:09 CET | GPUGRID | Not requesting tasks: don't need (CPU: job cache full; NVIDIA GPU: not highest priority project)This line explicitly says that your BOINC manager does not request work. The project can't send work to a host which does not request it. "NVIDIA GPU: not highest priority project" is definitely WRONG!!!This is a very good observation, so there's no point in clicking on that button without changing some settings. GET THAT PROBLEM FIXED!!!Sure, but you've forgotten to say the magic word. Otherwise GPUGRID will be dispunged!Perhaps you've learned from Shakespeare to threaten the forum, but tell me how much loss would be a not working host for the project? Your threatening is exactly that much serious. To solve your problem: I think your work buffer cache settings are inappropriate for the number of projects your host are attached to. I would increase the work buffer, or reduce the number of CPU projects on that host. | |

So 31 Jan 2016 22:56:29 CET | | [work_fetch] target work buffer: 864000.00 + 864000.00 sec10+10 days is a very long buffer, as GPUGrid has a 5 days deadline, a 1 day +50% bonus and a 2 days +25% bonus. GPUGrid gives at most 2 WU per GPU for a host, so there's no point in setting longer work buffer than the time it takes for your host to process 2 GPUGrid tasks. So 31 Jan 2016 22:56:29 CET | | [work_fetch] --- project states ---REC stands for Recent Estimated Credit. By default the BOINC manager takes a period of 10 days as a base for this estimation. You can set a shorter period in the cc_config.xml file by using <rec_half_life_days>X</rec_half_life_days> I recommend to you to set the REC half life for 1 day, and check if it results in the desired behavior.If not, then you should try a lager number, or a multiply of 10. prio stands for "task requesting priority" (not the same as the "resource share" you set in the BOINC manager) It is clear from the above list, that GPUGrid is not the highest priority according to the BOINC manager's calculation. The reason for that is GPUGrid gives very high credits for it's (long) tasks compared to other (GPU) projects which have to process much more workunits to achieve the same amount of credits (hence their larger priority). If you want to focus on GPUGrid, it is advisable to have less GPU projects on the same host, or set the other project's resource share to 0. In this case the BOINC manager will request work from these projects when there's no work available from all of the non-0 resource share projects. You can try to disable GPU tasks in your profile on other project's webpages in a venue created specially for GPUGrid hosts. This "task requesting priority" calculation is not well documented, but it can mess up when there are many mixed (GPU-CPU) projects in the BOINC manager. | |

So ... now that you can read a little bit about the numbers BOINC has calculated (see below) ... now you can figure out why it chooses to ask a particular project for work, and how much it asks it, and also why it doesn't ask for work. So 31 Jan 2016 22:56:29 CET | | [work_fetch] target work buffer: 864000.00 + 864000.00 sec ... 864000 = 10 days ... So you're asking "Always maintain at least 10 days of work, but if you're going to ask a project for work, ask to fill the buffer to 20 days." Watch your CPU buffers: So 31 Jan 2016 22:56:29 CET | | [work_fetch] --- state for CPU --- ... We need 2450042.84 instance-seconds (28.3 instance-days) to completely fill the 20-day buffer for all CPUs ... There are 0 idle CPUs ... We are saturated with work for all CPUs, for 1104595.60 seconds (12.8 days) ... So, because 12.8 > 10, and no CPUs are idle, we don't need to ask for work. Watch your NVIDIA buffers: So 31 Jan 2016 22:56:29 CET | | [work_fetch] --- state for NVIDIA GPU --- ... We need 747556.56 instance-seconds (8.65 instance-days) to completely fill the 20-day buffer for all NVIDIA GPUs ... There are 0 idle NVIDIA GPUs ... We are saturated with work for all NVIDIA GPUs, for 980443.44 seconds (11.34 days) ... So, because 11.34 > 10, and no NVIDIA GPUs are idle, we don't need to ask for work. End result: So 31 Jan 2016 22:56:29 CET | | [work_fetch] ------- end work fetch state ------- ... as expected. If you find something misbehaving (note: not likely), then please send this type of Work Fetch debug, either to this thread, or privately to me. I basically helped David A optimize BOINC work fetch a while back, and I'd be highly interested in any misbehaving :) Good luck! Jacob | |

Hello! After a long hiatus, and a move, I am back. We can't see the characteristics of your GPU when we click on the characteristics of your computer. Are you sure that your GPU is well recognized by your BOINC Manager?  ____________ [CSF] Thomas H.V. Dupont Founder of the team CRUNCHERS SANS FRONTIERES 2.0 www.crunchersansfrontieres | |

In fact I got a newer computer, also crunching WorldCommunityGrid.Are these tasks using your GPU? In any case with the 1060 GTX 3 GB and an I7-7700. I should be able to do much better than with the GTX 770.That's true, but your GPU doesn't show in the connfiguration of your host. I haven't crunched in a while and settings have not changed that I know of...so why am I not getting new work? Server status shows WUs available.Most probably you've installed BOINC manager as a service. In this case it can't detect and use your GPU. Check the event log of your BOINC manager after startup. If you see a message like "executing as a daemon" or "running as a daemon" then you should uninstall and reinstall BOINC (without checking the "service install" option) to fix this. Every time I try update in BOINC I get "communication deferred."That's only the end of the story, the reason why it's deferred can be found in the event log. You should see messages like "GPUGRID | Requesting new tasks for CPU and NVIDIA GPU". You should also check if you see your GPU listed in the first ~20 lines of the BOINC event log (after startup). | |
