Actually there is more work, has been the last week. Not enough to result in a backed up queue on the server status page - But my machines are set for a two-day queue and haven't run out of work yet. Big back-ed up queue on sever status page is not equal to "no new work" Might take a day or two to get a new model - but they are there. |

I think it is luck of the draw. I have work buffer set for three days but since I fixed my fresh install of Ubuntu by adding the 32bit libs, i haven't had any work. Not sure but I think I trashed my ssd on netbook by crunching so either no crunching when I replace it or I go back to the old fashioned mechanical disk! |

Luck of the draw is the word. No work is false. Keep crunching! |

My work buffer is as the default. How do I increase it? I assume you modify the <work_buf_min_days>0.100000</work_buf_min_days> <work_buf_additional_days>0.250000</work_buf_additional_days> in Global Prefs, but to what values? Thanks |

I ususally increase mine to the maximum allowed 10 days but as I am crunching WCG till I can get some CPDN work I have set it to three days at the moment. If using BOINC manager you can use tools>computing preferences>network preferences to do it through the GUI. |

ed2353 Or it can be changed on the projects web site. There's a button in the Projects tab that takes you to your account page. Note that for BOINC version 6.*, the values are 10 (days) + 2 or 3 (extra days), but for version 7.*, it's the other way around. The first value is the "high water mark", and the second figure is the "low water mark". And the work cache starts at "high", decreases to "low", then refills. |

Eirik, Misty There has been NO big batch of new work loaded to the queue, or announced, (privately or publicly). If there IS work, then it's resends from failed/abandoned work, and/or auto-regens from returned, completed, models. |

Thanks Les and Dave. I don't know how I did not see those options when I looked originally. I'll blame it on my age I guess! |

Interesting Les, I hadn't noticed the change when I went on to 7.x. Just checked however and I have filled it in the correct way around. :) |

Hi Dave Yes, it's a bit obscure; depends on how much people read the BOINC/dev site messages, or the Release Notes, or the FAQ: BOINC 7.0. In the Notes it's near the top under Scheduler changes; in the FAQ, near the bottom under In finer detail. |

Eirik, Misty Yes I�ve noticed that the WU�s that I have been getting lately all seem to have final numbers that are 3 or 4 indicating that these are reissues. One thing that I have been wondering is, is it possible to set different work buffer settings on the same machine for different projects. When I am running only CPDN (most of the time) I keep the work buffer set at 10 days so that the machines starts to beg for new work as early as possible. I feel that this helps keep all my cores full when work is scarce (which is most of the time now). When I do have an empty core or 2 because CPDN has no work I allow it to run other projects. The problem is that I have to remember to change the work buffer setting (usually to 0.5 days. I don�t want to download 10 days worth of work from MaleriaControl or WCG!), then change it back to 10 days to troll for CPDN work. Is it possible to set different work buffer settings for each project, such as by telling one project that the computer is at home and another project that the computer is at work? |

I don�t want to download 10 days worth of work from MaleriaControl ...:) Yes, been there! And the solution IS, as you say, to use different venues. |

I've not extended buffer time, staying at 2 days - have several idle cores and want them ready when work arrives to get fast turnaround. (And doing statistics on per-core and ht-core productivity) Fill in a bit with other fave projects -give their tiny wu-s low buffer time. Trying to keep my mini-server farm upgraded, stable, and ready for the next big batch to hit the fan, when and if :) Keep on crunching. e |

Finally got a task, though it has a, "4" at the end of it. I preesume that means it hasn't completed for three other people. The others in the work unit have either errored out or timed out with no response. will see how it goes. |

Looks like another batch of 3CNs have been pulled. Only just over half way through mine so they would have gone by the time I was ready for more anyway. |

I got three of these. I aborted them and now someone else is running them... |

Just to confirm. WU�s that start Hadcm3n_7o0n, Hadcm3n_7kqc, Hadcm3n_79ze, Hadcm3n_7dj7 and Hadcm3n_7dj8 all for the year 1980 are the escapees and should be aborted? |

Right, but aborting them seems of little use as long as they are picked up by someone else immediately. |
