I'm not getting enough WU Tasks downloaded to keep my GPUs crunching? I've set my preferences to 10 days minimum, and 10 days additional work buffer. is it something todo with the CPU, I've got enough for the CPU to be busy, with 10 threads, but my 2 x GTX590s, crunch 8 WUs in no time at all, and all the WUs downloaded are then set to ready to report. e.g. currently got to 5 x Ready To Report: Local Setiathome_enhanced 6.03 20 x Ready To Report: Setiathome_enhanced 6.10 (cuda_femi) 67 x Ready to Start Local Setiathome_enhanced 6.03 Some Astropulse ones running at present and a few to report. It seems, I'm often stuck in Ready to Report modes, or have I got the Balance wrong, and should turn OFF CPU! Any advice? |

Just now there are limits on the number of tasks "in progress", I think they are one hundred per processor. Now this may be 100 per processor type, so you are hard on that limit. If it is 100 per processor it would be reasonable to expect your big machine to report 500 "in progress". There are quite a few reports of upload & download problems, so don't panic as everyone is probably in the same situation with tasks not being transferred or reported as smoothly as one would expect/desire. ("In progress" means not actually being worked on, but have been assigned to, but not reported by, a particular machine) Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Firstly, Setiathome at present has a limit of 100 CPU and 100 GPU tasks, so setting 10 + 10 days won't get you extra work, and will likely get you less work because the High AR work only has a deadline of 14 days so won't be sent, Secondly, Boinc 7 has a new Scheduler that operates differently to the scheduler in Boinc 6, setting 10 days Minimum and 10 days Additional will make Boinc 7 try and fill up to 20 days work, then it won't ask for work again until it gets below 10 days work, a Cache setting of 3 days minimum and 0.01 days additional is more appropiate, Boinc will fill to 3.01 days work, and every time it goes below 3 days work it'll ask for more, BOINC 7.0 In finer detail Claggy |

okay, I'll adjust to 3 min and 0.01 days. I did wonder, if it was just home desktop computers, had got too fast for Seti WU/s! |

Mine keeps about 100 wu cache for the cpu 8 at a time and 100 wu for the 2 gpu 2 at a time that is 4 wu at a time total for gpu. BOINC keeps it around 100 all the time for the cpu and the gpus. |
