Recently, the following message has been logged each day (the amount of days overdue changes): 1/24/2008 1:28:40 PM|climateprediction.net|Task hadcm3iozn_cpm4_2000_80_45898965_7 is 1.65 days overdue. 1/24/2008 1:28:40 PM|climateprediction.net|You may not get credit for it. Consider aborting it. The actual elapsed time when that message first appeared was 846 hr. 48 min., with time remaining as 939 hr. 37 min., and the work unit 36.7% complete. However, in my experience the \"time remaining\" has constantly increased and has never been accurate. I have estimated the total time needed to complete the model as follows: elapsed time / percent complete = time to complete 846.75 hr. / 0.367 = 2,307 hr. That total amount of time required to complete the term of the simulation has remained constant since I began calculating it that way when the percentage complete was only 5%. I don\'t know whether \"credit\" matters, but I would prefer to run the model for the complete intended length of the simulation. It sends a \"trickle\" about once every 10 days, and uploads some large .ZIP files about every 8 to 12 weeks. That said, given the cost of electricity in the area where I live, I cannot financially afford to run the computer 24 hrs. per day, seven days per week. At most, I usually run it about 6 to 10 hrs. per day on most days, and run it about 4 to 6 hrs. on one or two days each week. So the completion of the work may be \"too slow\" to suit the project manager(s), and if that is the case, then I will abort the simulation and detach from the project. Note: the computer has an AMD Athlon XP 2400+ CPU, running at 2.0 GHz but comparable to an Intel CPU running 2.4 GHz. It can use as much as 1031 MB of RAM when the computer is inactive, or 768 MB when other applications are being executed. Should I abandon the model?? | | --- Stardance | | nil carborundum illegitimi |

There are lots of people on the BBC project still, who are in the same \"slow boat\" as you. And your model seems to have a very short deadline; it\'s suposed to be one year, not 5 months. Keeping it going at your current rate is OK, but if power costs are a problem, then Detsaching from the project may be best, once that model has finished. (Although there ARE some shorter models available, from an option in prefs in your account.) |

Keep plugging away at it. As far as I know, the result files are always accepted even if the Web site is complaining that the model is overdue or errored in some other way. On this project the credits will always be allocated if the trickles are submitted - there\'s no quorum or deadline. |

I have a similar circumstance and a near-identical message. Should I let it run or abandon? N.B. I have restricted the preferences to run one model at a time but it won\'t use me than 50% CPU.

You have a P4 CPU -- Hyperthreading, not Dual Core. Hyperthreading adds ~18% to throughput, at cost in total wall time. On the other hand, Windoze thinks it has two CPUs and reports a max of 50% usage if only one job is running. In fact, it\'s 80+%. To my knowledge there\'s nothing you can do to push something down the pipe faster, short of overclocking the machine. (Edit: there is one other thing that might help the machine, overall, and that is another 512 Meg of memory. Memory is VERY reasonably priced lately.) If you allow the Model to run, it will be accepted and used, regardless of boinc messages to the contrary.

Just to make it clear for future readers of this thread: There is no deadline in this project!!! Don\'t abort models because they\'re taking a long time to finish!!! If they ARE taking a long time, then allow a greater percentage of \"BOINC time\" for the model. |

Thank you. Point taken! Incidentally is there away to allow more \'BOINC time\' if I only have the one model running and very little else running on the machine? |

I\'d suggest the following settings: Your account / General preferences * Work when in use = YES * Leave in memory = YES * Use at most: 100% of cpu time Make sure that you don\'t have unnecessary software running (i.e., in the \'startup\' folder, or in the system tray). Uninstall anything you don\'t want anymore (control panel / add/remove programmes). Defragment the PC once in a while (every couple of weeks or so) - shut down Boinc just before doing that. See the READMEs for some more tips :-) (link in my signature). I'm a volunteer and my views are my own. News and Announcements and FAQ |

Austin In your case, not much, as you\'re NOT running other projects as well. Some things: 1) Add more memory. This will mean that not as much disk swapping occurs. It also makes the computer run better when using it for other programs. 1 gig is enough for your computer. 2) Wait until after a save point is reached before shutting down BOINC. That way, less model time will need to be re-run next time. (There\'s a count down timer visible in \"Show graphics\" - Press Z to get rid of the overlay on the left, and 8 to activate the timer. Wait until after it reaches a high number again. {The HD light will flash for a while.}) 3) Update your graphics card driver. This is the most common cause of the \"107.....\" errors you keep getting. 4) Run the computer 24/7. This is not an option / not wanted by some people. |

Thank you. Point taken! You could disable hyperthreading in the BIOS. That\'ll boost the processing power up to the full 100%. "The ultimate test of a moral society is the kind of world that it leaves to its children." - Dietrich Bonhoeffer |
