Is this in error I have been running 2 and both need 56 Days to complete. | |

Let it run - that's a BOINC "quirk" | |

Let it run - that's a BOINC "quirk" Even after 4 and 5 Hours? Even the Elapsed time is incorrect! | |

Even after 4 and 5 Hours? Yes .... think about the massive and unknown variations hardware and software throw at BOINC. BOINC has to cope with unknown hardware, unknown software and unknown program languages/protocols, just cant be done any other way. If you want a peek at whats involved - take a wonder around BOINC Trac: BOINC Trac Wiki front page: http://boinc.berkeley.edu/trac/wiki Current Job List: http://boinc.berkeley.edu/trac/query This one is rather like The Common Cold - every generation comes along and mutters "this should have been cured by now" ...... meanwhile, several generations later - they are still trying rofl. This particular time prediction is famous in BOINC - its their "common cold" - there are so many different variables and conditions, its still not been cracked, and frankly never will be. We just have to put up with the inaccurate initial predictions - they get better over time, and it disappears as a problem - until you move to the next new application rofl :) | |

I see all you have are I7 cpu's and your initial post shows 8 cpu units running AND 1 gpu unit running, try setting your pc to only run 7 cpu units at a time leaving the 8th core free to feed the gpu and see if that stabilizes and speeds up things. Your gpu could have lots of idle time waiting to be fed, and since they can produce 10 times the work in the same amount of time it can be worth a try. | |

I have 6 GPUs running and 4 CPU running on an i7-3770K, Should this not me ok? 5888176 5497884 25 Apr 2014, 21:52:55 UTC 26 Apr 2014, 17:20:16 UTC Completed and validated 63,808.63 7.96 238,583.14 Large Collatz Conjecture v6.04 (cuda55) FYI, You cannot use https for image tag. | |

My workunit said it was going to take 1733 hours to complete. The BOINC client isn't very good at estimating time. But the more workunits you run the better the estimates will be. So far I've been running it for about 6 hours and its at about 20% complete, so I'm looking at a 30 hour completion time. (I've been estimating the time since it hit 1% and it has stayed pretty consistent at 30 hours completion time, give or take an hour.) | |

My 7 first WUs are estimated to last 19H by the BOINC client, but I think they won't last more than 6 hours :) | |

Should these settings just be in plain text? | |

On my R9 290X with the correct settings in the .config file, I don't need to free a CPU core to feed the GPU :) | |

If a Collatz WU is 10% done after 10 minutes, then it will take 100 minutes to complete the WU (e.g. 0.1x = 10 minutes, so x = 100 minutes). Yep, it really is that simple to compute. | |

Mine got itself more or less sorted out after the second or third WU was completed. With default settings, it ran in about 17 hours on my GTX 670 | |

Two things to check: Thanks, I did set the file but still only see 0.01 on each 6 projects now running. I have to wait until my other CPU projects complete and then I will see if it get any better with running only GPU Projects. Somehow some collatz CPU Projects started up even though I have them turned off, as I only run collatz on my GPUs. verbose=1 items_per_kernel=21 kernels_per_reduction=9 threads=8 sleep=1 | |

I did set the file but still only see 0.01 on each 6 projects now running. The CPU setting is inside the app_config.xml inside your Project Directory. You set an app_config.xml inside each individual Project Directory - its not one size fits all. Below is mine at present for Collatz (I don't go a lot on CPU WUs, I just run four as I use the beast for other things whilst its crunching) - that uses 6 out of my 12 Cores for Collatz <app_config> <app> <name>solo_collatz</name> <max_concurrent>6</max_concurrent> <gpu_versions> <gpu_usage>1.0</gpu_usage> <cpu_usage>1.0</cpu_usage> </gpu_versions> </app> </app_config> Strictly speaking you only need a maximum of 0.5 CPU per GPU at Collatz (some will get away with less, but its not worth messing, just give it a min of 0.5). The above will run 2xGPU WUs (one per card supported by 1xCPU each GPU WU)) and 4 x CPU WUs. Change values to suit your setup/wishes. I give it 1.0 CPU per WU (which is way over the top) as I have the cores spare, you can go below 0.5 ..... but be very attentive to the resultant speed.... I just leave it at 0.5 min, 1.0 maximum and have done with it !! Keep your eye on CPU temperatures ..... you may need an app to monitor them depending on your setup, this one is as good as any as such: http://www.techpowerup.com/downloads/SysInfo/Real_Temp/ Real Temp will not work on AMD 1090T's or below, but any more modern than that, its fine. If you have not got a favourite CPU Temp util - that one will do the job. 0.01 CPU will make it feel as though there is a Tonne weight around its neck :) | |

My 2 AMD show 0.88 without adding any to the config file. | |

OK I set my app_config.xml to the below. | |

My 2 AMD show 0.88 without adding any to the config file. If that were me, I'd explicitly set the app_config file, doing that you remain in control and not The Beast working to defaults - the latter can be a "moveable" beast depending on the app :) EDIT: Cross posted .... :) re below - okie doke :) Make sure its set for what you want/need, that's for my Beast, it if fits what you want to do, that's fine, but do revue what you want to happen, and what its set for. Used "as is" on your machine that should feed GPU WUs one each to each of your Cores. | |

Show this <name>solo_collatz</name> be In theory yes .... but I have not used that config file explicitly for the Large WUs, and I am not certain what the file title will be inside <name>????</name> Be attentive to the result, because it may not be "large_collatz" as a title for the name clause. | |
