Posted 21 Jun 2011 by Bill Walker Post: Interesting thread. I have been using Norton for about 11 years now, on all my machines running BOINC. I've never had any BOINC files flagged, and I never set anything in Norton to allow this. I wonder what the difference is? |

Posted 20 Jun 2011 by Bill Walker Post: As to data traffic..we're streaming HD movies these days..are you seriously gonna tell me data traffic of this nature is still an issue? LOL Server load? come ON If this project had Netflix' or Youtube's hardware budget I expect things would be smoother. Don't hold your breath though. ;) ..computing power is so dirt cheap these days it's pretty much made BOINC obsolete altogether. I really don't follow that one. BOINC exists because little projects like MW can't afford computing power. They solicit it from us. |

Still have probelms with n-body WUs
(Message 49182)
Posted 8 Jun 2011 by Bill Walker Post: Every time the n-body task restarts in BOINC I get a Windows error message, "Task ended in error". I sometimes get 30 or 40 of these before the WU gives up with about 10 or 20 minutes of actual CPU time (compared to 300+ hours estimated run time when it downloads). BOINC task list shows "computation error" for the task at that time. All my n-body WUs have had this behaviour for several weeks now. Just an observation: the BOINC message list shows the task restarting, but doesn't ever show it stopping. It appears to be Windows that kills it. Also note that no other tasks are show starting in between the MW restarts (this machine has 2 CPUs, and usually runs 3 or 4 different projects). I've tried reloaded the C++ library, as suggested in another thread. Just got another n-body WU, waiting to see what happens with this one. |

How are you guys able to run so many diff project at once effectively?
(Message 47531)
Posted 11 Apr 2011 by Bill Walker Post: This has been discussed several times before here and over at S@H, but when you add a new project the BOINC scheduler appears to go bananas for a few days. I think it is trying to bring the new project up to its assigned percentage, and it will not run other projects that are closer to their assigned share than the new projects (which starts out with a history of zero % actual share). When you add a new project without adjusting the numeric value of the resource share of existing projects their % share goes down, so the scheduler thinks they are all over done at the moment (actual % will be over the new target %). Emergency mode keeps you from timing out on anything (at least in my experience), and it will all settle out in a few weeks. Added in edit: you will also see this if a project goes down for a long time, and then comes back. Historical share has dropped, but target % remains, and the scheduler gives preference to whatever project is most out of whack. |

Posted 7 Apr 2011 by Bill Walker Post: Since my GPU machine went wonky, I'm only running a dual core laptop, with 4 projects (MW, S@H, WCG and Rosetta). Partly because I'm interested in lots of different projects, partly because I've seen two or even three projects run out of work at the same time. RAC per project is low, total RAC is relatively low (WCG and Rosetta aren't as good as MW in credits/hour), but who cares? |

Failing workunits
(Message 43414)
Posted 2 Nov 2010 by Bill Walker Post: Ski King, it can takes weeks for BOINC to even out the work history of all projects when you add a new project. In effect, BOINC is looking at the long term average CPU useage of all your projects, and trying to even them out. If you just added MW, its long term average is very low, and probably much lower than the projects you have been running. Right now, BOINC is using all your CPUs on MW, so its average goes up some every day, while the long term averages of the other projects goes down some every day. Once the averages are roughly equal, BOINC will start sharing the CPUs between all the projects. |
