I've notices the CPU is not getting any work at all. | |

And what do you see in message log? Does BOINC client asks for CPU work and doesn't get it or it doesn't ask for CPU work [What number of request in seconds]? | |

And what do you see in message log? Does BOINC client asks for CPU work and doesn't get it or it doesn't ask for CPU work? As you can see, it asks for CPU work only. I was building an additional in BoincTasks. If GPU work > 2 day and CPU work < 0.5 day set buffer to 2 days. That's when I noticed the buffer staying on 2 days for a couple of days and no CPU work except for some AP work. ____________ TThrottle Control your temperatures BoincTasks The best way to view BOINC Anza Borrego Desert hiking | |

But I think I see what's going wrong. | |

After correction that problem in BoincTasks, the results are still the same. | |

Go to preferences, network connections, click 'clear' | |

And set at least the <sched_op_debug> logging flag in cc_config.xml so that you can see exactly what's going on when work is requested/received. | |

Done: 68079 SETI@home 17-10-2012 12:19 [sched_op] estimated total NVIDIA task duration: 7555 seconds 68078 SETI@home 17-10-2012 12:19 [sched_op] estimated total CPU task duration: 0 seconds 68077 SETI@home 17-10-2012 12:19 Project requested delay of 303 seconds 68076 SETI@home 17-10-2012 12:19 [sched_op] Server version 701 68075 SETI@home 17-10-2012 12:19 Scheduler request completed: got 22 new tasks 68074 SETI@home 17-10-2012 12:18 [sched_op] NVIDIA work request: 6868.66 seconds; 0.00 devices 68073 SETI@home 17-10-2012 12:18 [sched_op] CPU work request: 2080512.00 seconds; 8.00 devices BOINC request work and gets GPU work just above the value needed. Gets 7555 needed 6868. But there I expect it goes wrong. 687 is 76 for GPU to handle. So it gets just about the GPU it needs and hoovers just below the threshold. Is should get at least number of GPU * scheduler interval. + something extra. 9 * 6 * 60 = 3240 it gets 687. I see this line: 68074 SETI@home 17-10-2012 12:18 [sched_op] NVIDIA work request: 6868.66 seconds; 0.00 devices Does it know how many GPU tasks are running ????? ____________ TThrottle Control your temperatures BoincTasks The best way to view BOINC Anza Borrego Desert hiking | |

I've noticed that 7.0.28 will keep asking for GPU work until it gets to about 1.25 days more than my min + additional setting, and even at that level it will ask for a few thousand seconds of GPU work. I use local preferences of 6 and .01. I don't get much CPU work until it gets to 7.25 days of GPU work per BOINCTasks' sum of estimated times. You can intervene and temporarily turn off GPU fetch in the SETI@Home project preferences (website). I have do this about once a week to rebalance the cache. Of course, that would affect all of your hosts unless you are using venues (home, school, etc). Does it know how many GPU tasks are running ?????It seems to respond when I change my count setting. ____________ Another Fred Support SETI@home when you search the Web or shop online with GoodSearch and GoodShop | |

But I expect you get no problems if you have one GPU. ____________ TThrottle Control your temperatures BoincTasks The best way to view BOINC Anza Borrego Desert hiking | |

Of course, that would affect all of your hosts unless you are using venues (home, school, etc). Agree my situation is simple with one host and one gpu. The project preference "use NVIDIA (or ATIa) gpu" only tells BOINC to not ask for gpu work. Turning it off will cause BOINC to only ask for cpu work. Definately not an automated approach - hope you find a better way. ____________ Another Fred Support SETI@home when you search the Web or shop online with GoodSearch and GoodShop | |

Turning it off will cause BOINC to only ask for cpu work. Definately not an automated approach - hope you find a better way. I tried to automate something like that. But even though the computer asks for CPU work it gets noting. Another computer that request in the same period, gets work ever single time. But just enough to keep the GPU buffer filled..... Probably there is something wrong with the BOINC scheduler. At least for computers with more GPU's ____________ TThrottle Control your temperatures BoincTasks The best way to view BOINC Anza Borrego Desert hiking | |
