Amicable Numbers has slowed down
(Message 1012)
Posted 9 Dec 2018 by Brent Post: OK. I've had enough! In the past, and for several months, I was processing 14-15 CPU work units per day at 6836.19 credits per unit. Then, around the 20 Oct, my performance dropped to 6-7 units per day. Then, around 19 Nov, my performance jumped back to 14-15 units per day. Then, a couple of days later, it dropped back to 5-6 units per day. Then, about Dec 6, it jumped back to 14-15 units per day for a few hours, then drop down to 1-2 units per day where it has remained. My repeated requested for assistance have come and gone and I am no longer going to donate my computer time and electricity for 1-2 units per day at 6836.19 credits per unit! Since all of this has occurred with no changes to my system hardware or software, I have to wonder if Amicable Numbers is suffering hacker attacks from idiots that are trying to get rich quick by gaming the crypto coin systems and creating issues for everyone else? But until I get word this issue is resolved, I am forced to abandon this project. |

Posted 28 Nov 2018 by Brent Post: Then why am I experiencing the slowdown if only the Open CL tasks should be affected. I am spending almost the same computer time and electricity to process almost half the workunits. And others are reporting the same issue which began about Oct. 20. Guess I angered the Gods, as now my processing has slowed back down to where it was. |

I am spending almost the same computer time and electricity to process almost half the workunits. And others are reporting the same issue which began about Oct. 20. I am reminded of the old Farside cartoon where the scientist in a white lab-coat is standing in front of a chalk board filled with complex mathematical equations and in the bottom right hand corner appears the words "and then a miracle occurs" Because suddenly, a few hours after this post, and with no action on my part, my workunit processing speed is back to what it used to be. |

Posted 17 Nov 2018 by Brent Post: Ok, so how do I avoid OpenCL so I am not wasting my computer time and electricity for less work?

Posted 15 Nov 2018 by Brent Post: All CPU tasks should be balanced to roughly the same execution time, they were generated with primesieve performance taken into account. it's only OpenCL version that will slowdown eventually. Ok, so how do I avoid OpenCL so I am not wasting my computer time and electricity for less work? |

Posted 2 Nov 2018 by Brent Post: Gee! If the numbers growing larger is causing the slowdown, way aren't the credits also growing larger. If it is taking twice as long to process a unit, shouldn't the credits be twice as much? |

Posted 31 Oct 2018 by Brent Post: I should add, the slowdown began around 10/20/2018 |

Posted 31 Oct 2018 by Brent Post: Same here. I am running Amicable Numbers CPU mode with 7 CPUs selected. This is on a Dell XPS 8900 PC with INTEL Core i7-6700 @ 3.40GHz, Windows 10 Home on 1 PC. I was processing 13-15 units a day but am now down to 7-10 per day. The main change was a recent upgrade to the latest Boinc software, but the slowdown started before this upgrade. |

Posted 13 Apr 2018 by Brent Post: I desperation, I reset the project and now it is working. I have 14 CPU units at expire in 2 days. |

Posted 13 Apr 2018 by Brent Post: Well I didn't change anything on my side recently either. Here are my settings Amicable Numbers preferences Resource share 100 Use CPU Use NVIDIA GPU Run test applications? No Is it OK for Amicable Numbers and your team (if any) to email you? Emails will be sent from Amicable Numbers BOINC project ; make sure your spam filter accepts this address. Should Amicable Numbers show your computers on its web site? Should Amicable Numbers show amicable pairs discovered by you? Default computer location --- Run only the selected applications (all applications) If no work for selected applications is available, accept work from other applications? yes Max # jobs No limit Max # CPUs You need to select at least 2 CPUs to get CPU tasks 7 Kernel size for AMD/ATI GPUs [?] 21 Kernel size for NVIDIA GPUs [?] 21 |

Posted 12 Apr 2018 by Brent Post: In early April, I signed up for the CPU work-units for my Dell XPS8900 running Windows 10 64 bit. Initially I was getting plenty of CPU work, but none currently. I do continue to get my NVIDIA GPU tasks. Is the problem something on your end or my end? Brent |
