Please, remind me again. Which type gets filled first of your quota after an outage? I always thought it was CPU first then GPU. Am I wrong? That is what I see on my Windows 7 computers. But to be different ... it is the reverse on my Windows 10 computer. Confused. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

I believe it was said it was the fastest processor first. For my computers it is GPU then CPU, even on downloads CPU is last. |

Well then, that makes no sense at all on my computers. It should always be GPU first then. But I am seeing the CPU's fill first on the Windows 7 computers but the Windows 10 computer always fills the GPU's first, then the CPU.

Wasn't it Win7 you have download issues with as well? Who said the scheduler made sense anyways :P |

Yes, I see the no work sent issue the most on the Windows 7 computers. The Windows 10 computer is mostly immune it seems. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

No problems here filling up once my rigs connect. 1 rig connected while I was mowing the lawn and I manually connected the other a half hour later when I ran out of fuel and that happily filled up in no time too, both are Win7 (1 Home Premium, the other Pro). Cheers. |

Did you use the same Lunatics installer on all them? Edit app_info versions after? Same apps for MB/AP on CPU/GPU? Just curious if apps listed in a different order might be an indicator. |

Yes, both have identical everything, BOINC (6.10.60), Lunatics (Beta 6 installer), app_ info.xml's, cmdlines, etc,... In fact, other than the different Win7 versions and wallpapers, everything software is identical on both of them, hardware wise, other than their CPU's and motherboards they could be identical twins. ;-) Cheers. |

Yes the same Lunatics Beta-06 installer. However, I have since hand edited in the r3584 SoG app to replace the stock r3557 SoG app. But I have never compared the ordering of the app sections between the machines. That is an interesting idea to investigate. Good suggestion. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

My Windows 7 machines ARE identical twins. Exact same hardware and setup for the most part. At least I built them that way in the first place.... as twins. There has been a change in motherboard and CPU on this daily driver compared to Pipsqueek though since they were built. The Windows 10 machine was a completely different beast. My first experiment with Windows 10 and just recently it had a brain transplant to AMD Ryzen 1700X.

Although the simple logic of fastest first would say the GPU sometimes I have noticed that my CPUs get refilled first. I can but assume that this is based on the availability of tasks suitable for the GPUs combined with luck.

That's the only part of the equation that is unknown at request fill time. It may just be coincidence on the Windows 10 machine. But I have my suspicion that the CPU change has caused the best part of the noticed effect recently. I don't remember that machine being any different than the other machines in the past. I wonder if BOINC thinks that the CPU on that machine finishes tasks slower than it did in the past. It is of course, just the opposite. I finish CPU tasks twice as fast now on that machine.

The mechanism is fastest device first. Exception is if your GPU is out of work it will fill the CPU first because Boinc reports the GPU as inactive. With each crime and every kindness we birth our future. |

This latest outage was a good time to see just how my three computers respond to being completely out of work on both CPU and GPU. The Windows 10 machine with the fast CPU responded exactly opposite how the mechanism is described by Mike. It downloaded nothing but GPU work until my 200 task quota was filled. It then started downloading work for my CPU. The Windows 7 machines however did not respond as the mechanism is described. Both machines downloaded both GPU and CPU work in dribs and drabs at the same time. Majority of the download request went into the GPU cache but every download put a few into the CPU cache also. So the BOINC mechanism to fill the fastest processor first did not work correctly on my Windows 7 machines.

since last outage i got cpu and gpu-tasks for the Nvidia-adapter but none still for the ATI ... the ATI is about 10x faster than the Nvidia. should i reinstall the client ? Message says request tasks for Nvidia and ATI but WU´s send are allways only for Nvidia. Cant find the error. Drivers ect are all up to date. |

Post ~30 lines of your BOINC startup log where it is detecting the GPUs |

since last outage i got cpu and gpu-tasks for the Nvidia-adapter but none still for the ATI ... the ATI is about 10x faster than the Nvidia. should i reinstall the client ? Someone had an issue some time ago. When they had no GPU tasks their CPU cache would fill to the limit and then they would get the "This computer has reached a limit on tasks in progress" message. They had to disable requesting CPU until GPU tasks started to download. Then they could reenable requesting CPU tasks.

killed all tasks not running, disabled nvidia gpu and rerun. no Tasks for the ATI only some for the CPU. Activated Nvidia gpu and rerun. Again some tasks for CPU and tasks for Nvidia, still none for ATI. The ap splitters are all off under serverstatus, anyone knows if they produce tasks for ATI cards ? Anyone knows a project i can add under boinc that supports ATI graphics computation to see if all is fine ? |
