Thanks in advance! > Nearly overcommitted means that the required time fractions for all of the results in the queue sum to > 0.8. The required time fraction for a result = Fraction of wall time spent processing * remaining processing time / remaining wall time till the deadline. In this case, the scheduler deems that it is better not to dig the hole any deeper and possibly get into the state of over committed. When over committed the CPU is in danger of not meeting some deadline.   BOINC WIKI |

Meet all of the deadlines (you do want to finish by the deadlines, right?). Honor the resource shares that you set up. BOINC WIKI |

Honor the resource shares that you set up. ========= @ John McLeod ... hahahaha really, well In my opinion it does a piss poor job of it ... I have the LHC Project set to 10,000 Resource & CPDN set to 1, so why does the 2 CPDN WU's I have one each computer continue to run endlessly even though I have LHC WU's waiting to run. The only way I can get the LHC WU's to run is to manually Suspend 1 of the CPDN WU's so the LHC WU's will start to run ... And don't give me that jargon about bring in debt to the CPDN Project. I don't owe any of the Projects anything, they'll get what I give them & nothing more ... All the Projects I run I set to 1 except for the LHC Project which I set to 10,000 because thats what I want running if I have any WU's available, I keep on top of my Computers and the WU's I have from the other Projects & I'll worry about the Deadlines of the other Projects...I don't need some manager forcing me to run what I don't want to run at the moment... |

My point of view is as simple as I am, just let me crunch! Just let get the clients the work, so far nearly never had any problems with dealined works. ========== @ Ric, exactly, just let me crunch & don't back me into a corner with some Manager thats overly restrictive & demanding on what, when, & which WU's I crunch ... |

Heck, I'm not sure the design goal of the manager for the most recent builds. I've thought to myself on more than one occasion wouldn't it be nifty if the BOINC client had a graphical method of making it easy to allocate time to specific projects? Then build on the idea by being able to apply those settings to the project servers. BOINC client could figure in the estimated completion time of each project's WUs to make sure sufficient time is allocated for such units to complete before their deadline. This implies the client will intelligently request a specific # of workunits (or # seconds) and warn the user if their settings would interfere with the completion of a given WU based on user (in)activity, project participation, estimate WU completion, WU deadline, and anything else I've forgotten that would be a factor. Should I post this feature request to boinc_dev? :)

One feature I would like to see implemented is to be able to select more than 1 WU at a time to Suspend or Abort ... I know you can just Suspend the whole Project which will Suspend all the WU's for that Project you have at that time but what I'm talking about is say you have 30 LHC WU's on 1 computer & want to just Suspend 10 or 15 of them at 1 time instead of having to Suspend each one individually ... |

I like the new v4.44 version even better than the v4.43, my computers will get lot's of rest as I see it. For 1 you can't get any work because it won't Request any & 2 if the Manager happens to screw up and actually give you a little work it just freezes up after a bit anyway & stops running the WU's... I went out to my Pole Barn for a few hours after I installed v4.44 on all my Computers & when I came back in the Manager on every one of my PC's was Froze up & wasn't running anything according to the Task Manager ... But I guess I can look at the Bright Side, my Computers will last forever at this rate ... :/ |

I also upgraded to 4.44 and it froze everything... CPDN was frozen at the very start running at 0.00% Downgraded to 4.25 again and now it's crunching at 48.61%... WinXP Home, P4 3.2GHz HT, 512Mb RAM./Win2K, P4 1.8GHz, 512MB RAM Join World Wide S.E.T.I.

Nice client version ... D'oh ... I finally just went back to v4.25 myself in order to restore some sanity to myself ... hehe |

I haven't had 4.44 lock me up yet, (knock on wood) but 4.43 (the recommended version!!!) did it all the time. Always a bummer to find you've been doing nothing for 10 hours. (assuming the CC will give you any work...)
