I have set@home and climateprediction running, prefs say 60 minutes appl switch, 25% climate 75% seti@home but once climateprediction gets control it never relinquishes. Also climate prediction has a reduced Projects menu - no Preferences button. I am running 5.8.11 |

I am running 5.8.11 CP has a time frame of a year in some cases, this means that your computer needs to get busy crunching or it will not be able to get them done on time. This will lead to what is called LTD or Long Term Debt. It will even out in the end, the end just being a while down the road. |

Actually, since he is running 5.8.8, there is another distinct possibility. That may be that BOINC is going to wait for a checkpoint before switching - and CPDN does not checkpoint very often. But it is also true that CPDN may be running into deadline trouble, and may need extra CPU time to complete on time. Yes, I know that the deadline for CPDN is a bit on the loose side, but that is not true of most projects, and the BOINC daemon does not have any way of distinguishing whether the deadlines are strict for that project or not. With the information given, I cannot tell which case is happening. BOINC WIKI |

I'm running 5.8.11 as I said in the initial post, and the CP deadline is 4/2/2008, so I doubt that's a factor. |

I have exactly the same problem. I haven't done any SETI work for months. |

The current CPDN 'coupled' models tell BOINC to do 1 full WU - that's 160 model years - in just under one calendar year. That would earn you 41,472 credits in 348 days, or just about 120 credits per day (taking the figures from my current CPDN WUs). If you haven't got a machine which can sustain a steady RAC of 120 or more on CPDN, BOINC will always think you're in deadline trouble. Darren's computer has a RAC of 48, and squeak's is around 50, so it doesn't surprise me that neither machine is switching projects. CPDN doesn't enforce the deadlines, and will accept whatever work you can do, but BOINC doesn't know that. I suggest that both of you decide which project is of most interest to you, and concentrate your energies on that one. By all means attach to a second project as a backup, because there are times when no work is available from the main project - but I would suggest that CPDN isn't really suitable as a backup. |

I'm (hopefully) building a new system next week based on the Intel E6300 CPU. I'm hoping I'll go above 120 with that? |

Should have absolutely no trouble at all, provided you have it switched on a reasonable proportion of the time, and don't spend too long looking at the pretty pictures (a.k.a. screensaver). |

I've built my new system now and it appears to be doing climateprediction and seti at the same time. Is it doing one in each core? |

If it is a dual core machine, then yes, this is quite possible (don't be surprised if occasionally the machine runs two of one of the projects and none of the other for a while). BOINC WIKI |

Well, after 3,408,813.34 seconds of CPU time the climate prediction client gave an error after crunching 20% of it. I'm fed up because it was doing this since August. Don't think I'm going to bother with that project any more. I think I've only managed to finish one unit in all the time on it. Time to look around for another project that is worthy for my dual core to crunch on. |

In regards to my post above; both the seti unit I was working on and the cpdn model gave errors. see: http://setiathome.berkeley.edu/result.php?resultid=488249762 and http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=5695358 I think this might have happened after I rebooted after I installed some drivers for my new mobo. Any ideas what caused this? |

In regards to my post above; both the seti unit I was working on and the cpdn model gave errors. On the Seti unit this message came up "<![CDATA[ <message> The system cannot find the path specified. (0x3) - exit code 3 (0x3)" Seems like you either shut down without stopping the unit and it crashed or you did more than just load new drivers. The climate unit has the same error. |

In regards to my post above; both the seti unit I was working on and the cpdn model gave errors. I never stop BOINC before shutting down. Didn't know you were supposed to. Anyway, that cpdn model is duff now. I wasted a lot of CPU time on it. |

In regards to my post above; both the seti unit I was working on and the cpdn model gave errors. It's should not be necessary to shut down Boinc before resetting your computer. This would seem to be just some random glitch probably associated with the update of the driver. I wouldn't worry about it unless it occurs again. Your CPDN crunching in not wasted. The trickle reporting at CPDN assures that what data you did provide will be useful and that you get the credit for the work you did. Because for their extremely long crunch time and the odds of something going wrong over months of crunching, I've come to the conclusion that a relatively small number of people actually complete a full WU for that project, unless they devote all their computer resources to it. I've yet to finish one myself, but I still crunch for the project on my faster computer which is only slightly faster than yours. My CPDN is at 29% with 1400 hr to go. This is the first one on my C2D and I'm still hoping to finally complete a WU for this project. As you can see from my signature I crunch for a lot of projects and feel I contribute in a small way to all of them. Boinc V7.2.42 Win7 i5 3.33G 4GB, GTX470 |
