I'm confused by the scheduling order.
(Message 51532)
Posted 25 Nov 2013 by John McLeod VII Post: There are a few ways out of the situation: 1) For extended vacations: Set all projects for No New Tasks. This tells BOINC to finish off the current work, return it all, report it, and then when you get back, you allow new tasks for all projects and it will start up again. 2) For vacation times less than 2 weeks: Set the work buffer using "Maintain enough work for X days" to a value slightly larger than the vacation time. This setting also pulls the completion and report deadlines back by the value of the buffer time. Do NOT use the Extra Work as that setting does not affect the deadline. 3) Somewhat less friendly, but will work is to just leave the settings alone and have some abandoned and late work when you get back from vacation. The science project will send replacements to someone else. |

Switch between applications between every
(Message 30917)
Posted 8 Feb 2010 by John McLeod VII Post: More correctly, it is an opportunity to switch between tasks. It is not always a switch between projects, but sometimes it will merely be a switch between tasks in the same project. This will occur if one task starts or stops needing extra CPU time because of deadline trouble. |

BOINC marked SETI as "overworked" and doesnt fulfill queue cache requirements
(Message 27183)
Posted 8 Sep 2009 by John McLeod VII Post: The basic calculation of STD has not changed - ifyour computer does not use a GPU. (More on that later). The major difference is that all STD values are non-positive. If something changes the STD of a project to be positive, all of the STD values for active projects are shifted so tat the maximum STD is 0. Active projects do not include NNW with no tasks, suspended, or projects at max deferral - unless it has been too long since the project was asked for work. Projects that are not active and not overworked will not have their STDs change. ** I am not certain of the state of STD versus GPUs. I do know that there was a problem with STD values for projects with GPU usage would go to negative infinity. |

Posted 29 Sep 2008 by John McLeod VII Post: New values from today Yes, there is a link beteen shortfall and work request, however, that is NOT how the work requests are ordered. The project with the highest LTD that is contactable gets first chance. The reason that projects with negative LTD values get a shortfall requested is to avoid having a dry CPU if there is no contactable project with a higher LTD. Calculating the shortfall does not affect which project is contacted for work. |

Posted 26 Sep 2008 by John McLeod VII Post: New values from today Since projects that are in communications deferral are already removed from these calculations, you are potentially double removing them which could lead to a negative total resource share. |

(Message 20441)
Posted 23 Sep 2008 by John McLeod VII Post: Ok, so you didn't unsterdand, sorry about it. It is already the case that if a project is being constantly asked for work and not providing any that the LTD does not increase. Your proposal is much more drastic in that in not only stops the increase, but drops the LTD to 0. The time before the LTD drops to 0 is completely random in that under some circumstances a project can be asked for work every minute or two, and under others it can be days between requests. Setting up for the days between requests could mean that the standard S@H outage is enough to trigger the reduction to 0. |

(Message 20424)
Posted 23 Sep 2008 by John McLeod VII Post:
What I understood. If a project is running long term in EDF, no other project would ge asked for work. Those projects that are not asked for work will get their loong term debts set to zero. Since all long term debts are shifted such that the mean long term debt is zero, the long term debt of the project that is hogging all of the CPU time will quickly become zero. Thus effectively removing long term debt and resource shares from the program when ooe project ends up hogging the CPU for a while. You have the same problem if your host is attached to many projects. The host cannot handle work from all projects at once, and starts zerroing out the LTD of projects for which work cannot be downloaded at the moment. Another thing that happens in that situation is that some projects end up with very large negative LTD values and aren't asked for work for a very long time. You r modification would reset these projects back to 0 LTD long before their resource share indicates that it is their time. |

Posted 23 Sep 2008 by John McLeod VII Post:
But you still have the problem where one task uses extra CPU time - the entire point of long term debt and resource shares is to share the CPU over time. With your modification, you might as well do away with these concepts entirely - leaving absoloutely no method of specifying how the projects should share resources. |

Posted 22 Sep 2008 by John McLeod VII Post: Hi, Really bad idea. Suppose that CPDN takes over for a year (yes, I have had this happen to some of my computers). Do you REALLY want CPDN to take over for ANOTHER year when it gets the first task downloaded (after a day or less of processing the other project)? What about your resource shares? |

Long term debt doesn't run down
(Message 20051)
Posted 9 Sep 2008 by John McLeod VII Post: I have a couple of projects where the long term debt doesn't seem to run down, even though work is available. Close. The lower the resource share compared to other projects, the faster the LTD drops when the project is actually crunching. The amount of work requested is based ont the projects that are eligable to get work requests or already have work on the system. Projects have a minimum LTD below which they normally do not get work requests. The exception is insufficient work on the computer and no candidates above the threshold that are allowed to havork requests. If SIMAP is the only project allowed to request work, and the only project with work on the system, it will fill the queue. The obvious question: What are your queue settings? If they are too large, the projects that have large negative LTD values will still be getting work requests because the ones with higher LTDs can't keep the queue full enough. |

Boinc v6.2.x requires reboot
(Message 19736)
Posted 24 Aug 2008 by John McLeod VII Post: It'll only happen when you update or install for the first time. Afterwards never again. Yes. The code was put in place in 6.2.16. So the 6.2.14 client did not not know not to do the uninstall as 6.2.18 requested (ouch that is a lot of negatives). The installer for 6.2.16 and later tell the uninstaller for the old version not to do the migrate back to the old location. 6.2.16 and later also honor this setting. 6.2.15 and earlier do neither. |

iPod Touch 2.0 app?
(Message 19624)
Posted 19 Aug 2008 by John McLeod VII Post: I tried to compile BOINC for the iPod touch 1.0. Gave up after a while, not because it was hard, but because I was running out of battery and the iPod was getting hotter than I like. (it was compiling on the iPod itself, not cross-compiling from my computer!) And as you discovered, running a CPU intensive project is going do run through battery in a huge hurry. Handheld devices are all about battery conservation. If you defeat this, you end up with a hot brick (literaly hot, and if it gets too hot, it will become a brick). If you don't defeat this, your benchmarks will look even worse (replace MIPS with KIPS and you will have it about right). |

There are three ways to make BOINC work. 1) (Best) Install 6.2.18. 2) (Second Best) Install 5.x as a service. 3) (Worst) Disable UAC (it is possible to do for a single application - at least I think I read a doc on how to do that.) |

(Message 19619)
Posted 19 Aug 2008 by John McLeod VII Post: Recently I started thinking whether some organization somehow is checking these projects. When I can be sure, whether somebody didn't create the fictional BOINC project, for example in order to break safety barriers and the like? There actually have been a couple of questionable projects. Anybody remember shoft? Caution on the part of users is the watchword. |
