credit difference
(Message 1892)
Posted 18 Dec 2025 by mikey Post: I still don't understand why projects keep using CreditNew, it's been a pain since it has been created ... Because it's the default meaning it's built-in into the Server side version of Boinc. to change it one Admin, not from here, said there were like 3 places in the software to change it. He said it was not as easy as it sounds!! |

why does it aslways say there are no 128 or 64 tasks
(Message 1872)
Posted 1 Oct 2025 by mikey Post: To be honest, I have no idea. I figured it out, I had less than 100% of the available cpu's scheduled to be used to keep the heat down and it was less than 128 cpu cores, I now have BOTH a 64t and a 128t task ready to run. mikey |

Posted 30 Sep 2025 by mikey Post: To be honest, I have no idea. Yes those assumptions are correct about my pc's, well I use a cc_config.xml file to make it think it has enough cpu cores available. And overnight I am getting lots of 64t tasks but still no 128t tasks. Here is the line where I do it: <ncpus>140</ncpus> mikey |

Posted 29 Sep 2025 by mikey Post: Why does it always say there are no 64 or 128 tasks when the Server Status always says a few hundred are ready to be sent out? I know it's behind but THAT much? |

YAFU version 212.02 for Linux
(Message 1823)
Posted 29 Jan 2025 by mikey Post: New version 212.02 for Linux. I am using Linux Mint and when I try to reset the Project it doesn't seem to do anything, most of my Linux pc's get tasks just fine, as do my Windows pc's but this one just won't. It's running Boinc version 7.18.1 so isn't that old. Never mind on the above I had it set to No New Tasks and once I clicked 'resume' everything worked just fine!! I have new tasks running on the pc now. Your message above says "resume should also work" but I don't know what that means, can you explain that please. mikey |

GPU support
(Message 1797)
Posted 11 Nov 2024 by mikey Post: Please add GPU support to the project. I don't want to discourage the Project from doing it but Boinc gpu programmers are not a dime a dozen and the projects don't share people like that between them. I wish alot of things would happen to Boinc, sharing people between them would help alot but each project just seems to do their own thing and even only rarely ask in the Admin Boards for help when they are having problems. |

What do YAFU credits do?
(Message 1742)
Posted 16 Dec 2023 by mikey Post: Why not whitelisted? That's weird IMO. The Project has to agree to be whitelisted and some projects think it will increase the cheating, it already did at Collatz just so people could get more GC's, so more than a couple of Admins don't want the problems. Credits themselves are worth nothing physically but do show your progress here at Yafu compared to other users here at Yafu. Credits should NOT be used to compare yourself, or anyone else either, and the credits at other projects. Each Project decides how to give out credits, some use this formula, some use that formula and still others give out fixed credits. |

Yafu threads
(Message 1657)
Posted 19 Nov 2022 by mikey Post: I have 32 logical cores cpu nad had 2 yafu task running 8cpu + 8cpu so half of cores were not utilized. Selected to receive YAFU-16t tasks and I got one YAFU-16t waiting to run on 32 cores ! You can always choose 'no limit' but yes if decide to limit the cores 8 is the highest and yes it needs to be updated to 32, though maybe not every number in between 8 and 32 |

Wrong Core Parameter on 8t WUs?
(Message 1631)
Posted 19 Jul 2022 by mikey Post: Yes, 4t now meams, that you need at least 4 cores. The wu uses all cores. So what does that mean when I choose to do the 8t tasks and choose this in the settings? Max # jobs 8 Max # CPUs 4 Does it mean it won't work or just take longer to run them? |

is there a secret to getting 16T and 32T tasks?
(Message 1597)
Posted 16 Apr 2022 by mikey Post: I have both windows and Linux pc's asking for 16T and 32T tasks and the Server Status says there are some but I never get any of them..is there a secret to getting them? I do have my pc's limited to 99% of the cpu cores meaning only 15 cores available...is that a problem getting these tasks? |

What's the Difference
(Message 1552)
Posted 19 Jan 2021 by mikey Post: I think the answer is "yes" Mikey. I figured that but am wondering if I NEED a 32 thread machine to crunch them? Can I for example fudge the numbers and use a 24 thread to make it THINK I have a 32 thread pc or do I even need too. The short answer is I can't seem to get any of the 32 thread tasks and me not having a 32 thread machine seems to mean I will never run them. |

YAFU running with GPU's
(Message 1547)
Posted 23 Dec 2020 by mikey Post: I'm running 4 GPU's Maybe, it depends on your machine and how the Collatz and Einstein apps deal with your 480's, some gpu's require a cpu core free for each gpu so they can run at their max of they are limited while others do not. The best thing to do is run a few cpu units using all the cpu cores and track the time used to crunch the gpu tasks, then suspend all the cpu tasks and track the time to run some gpu tasks again...which way is it faster. Since gpu tasks do over 10 times the work cpu's do it's better to optimize them and limit the cpu tasks. And THAT is why people end up with muplitple pc's, people hate to slow down so you get more pc's spread the gpu's out into separate machines and bang out a bunch of both. |

What's the Difference

Posted 23 Dec 2020 by mikey Post: The big ones use every core they can find if not constrained. So are you saying I need a 16 or 32 core machine to run the 16 and 32 core workunits? I know how to constrain them thru the settings but am asking as I do not own a 32 core machine. |

Credit reduced
(Message 1502)
Posted 12 Apr 2020 by mikey Post: Here is another example of incorrect CPU time -vs- run time: It seems your dual core pc's only have 2GB to 3GB of ram, I wonder if the task is spinning it's wheels due to not enough ram? Have you tried going into the Boinc Manager to see how much each task is using? Click on a running task and then to the left click on properties and near the bottom it will show something like this: Virtual memory size 33.12 MB Working set size 22.60 MB That's the number for a NON Yafu task as I don't have one running on this pc right now but you get the idea. |

How do I get YAFU to stop sending me tasks that use up 100% of my cores?
(Message 1405)
Posted 17 Jul 2019 by mikey Post: Hi YoYo, When you define your own class plans (<plan_class>16t</plan_class> & <plan_class>32t</plan_class>) don't you have to pass the client your plan_class_spec.xml file??? This is the app_config.xml file I use at another project to run 1 workunit at a time and use 4 cpu cores per workunit. It is a 6 core machine so only 1 unit can run at a time. Obviously you will need to change the "llrsr5" line to the app used here and put it in the project folder for Yafu. <app_config> <app> <name>llrSR5</name> <fraction_done_exact/> <max_concurrent>1</max_concurrent> </app> <app_version> <app_name>llrSR5</app_name> <cmdline>-t 6</cmdline> <avg_ncpus>4</avg_ncpus> </app_version> </app_config> |

Too many WUs!
(Message 1244)
Posted 25 Aug 2018 by mikey Post: That cache setting relies on BOINC calculating an accurate completion time. Yafu jobs run much longer than BOINC calculates. The only way would be to limit actual number of jobs retrieved and I don't see a setting for that in BOINC or in cc_config.xml options. <fetch_minimal_work> comes close, but it only restricts the number of jobs to the number of CPUs. They could use this setting under 'Preferences' "Max # of jobs for this project". I also use the setting "Max # of CPUs for this project" and set it to 2 so only 2 cpu cores are used per workunit. |

If you use a zero resource share it will only get one workunit per cpu that you allowed to get work in Boinc. For instance I have a 6 core cpu but am only allowing to use 99% of the cpu's so it gets 5 workunits. I reserve one cpu core to keep the gpu fed for the gpu workunits, from another project, I also do. |
