Why isn't the project GPU-only by default?
(Message 1401)
Posted 13 May 2020 by JohnMD Post: I am new here, so please be kind if I am totally off on this, and I apologize if I am. Uncheck the CPU box in Amicable preferences if you don't want to use your CPU. The project just wants to get as many WU's done as possible ! |

Um, Got a Couple of Whoppers?

Posted 19 Apr 2020 by JohnMD Post: I returned the following task yesterday https://sech.me/boinc/Amicable/result.php?resultid=30879313 it ran for just over 52 minutes. It took the other person over 4 hours on an AMD card. I am just wondering why this took such a long time to run and whether or not it was related to the tasks quite some time ago that got granted more credit? Unfortunately I am unable to find that thread Don't you know that - 1) Some people don't have as good equipment as you. 2) Some 'wingmen's tasks terminate without a result, and have to be resent to a another cruncher. 3) Some cruncher-wingmen accumulate a task queue with up to 10 days' work - you need to wait those days before your work can be confirmed. We are all volunteers - some more voluntary than others ! Have patience - your efforts are not in vain. |

Posted 25 Mar 2020 by JohnMD Post: A reboot of my laptop seems to work. Note that the start phase of these WU's requires 3GB RAM - you'd be hard pushed to start 2 at a time, and certainly not 3. |

Posted 31 Oct 2019 by JohnMD Post: In my experience, IBM's OS2 was the ONLY PC system that could efficiently handle virtual storage. Forget upping swap-file. Buy some more RAM ! |

Posted 28 Oct 2019 by JohnMD Post: Note that system memory requirements are higher now because all prime numbers < 1011 need to be stored in memory for the search. Resources per CPU WU are doubled - both memory and CPU-cycles. Shouldn't credit follow suit ? Can't the allocated cores share a single copy of primes in memory ? |

Posted 20 Oct 2019 by JohnMD Post: What would the RAM requirement be for the search to 10^21? I would guess that it wouldn't quite be a 10x jump to 15GB, but it could still be quite substantial. 1400MB seems to be about right for 2 cpus. Up to 1000MB is released and re-allocated every minute. While 'used memory' is reasonably stable, allocated memory gradually increases. This might be Windows' fault - but it might also be forgetfulness by Amicable. Answers please - on a postcard - to - boinc'ers with small machines ! |

Computation error
(Message 1102)
Posted 13 Mar 2019 by JohnMD Post: I get the same "-58" in 2 situations with Nvidia 930M (I also have Intel 520 for display) 1. When I close BOINC and restart. The GPU app CAN'T restart, even though it has created a checkpoint file. 2. When I switch to another user, the GPU app gets suspended. When I switch back it CAN'T resume, even though suspended tasks are 'kept in storage'. Sounds to me like something's been forgotten and the program not properly tested. |

Posted 22 Apr 2018 by JohnMD Post: Most of my NVIDIA graphics cards are larger than 1G, and it seems that the device has not been able to get the task changed just a few days ago. Your hardware is hidden, so it is not possible to help you. |

GPU version requirements for the search up to 10^20
(Message 792)
Posted 18 Apr 2018 by JohnMD Post: Current GPU version's requirements: any AMD (HD 5xxx or newer) or NVIDIA (GTX 4xx or newer) GPU with OpenCL support and at least 2 GB of video memory Now that WU's allocate less than 900MB, is it possible to relax the GPU memory requirement to 1GB ? |
