Yesterday I had to reboot my Linux computer, and when I restarted Boinc, the software downloaded a new model and started working on it, even though the previous one (with more than 85000 TS calculated) was not finished. Is this normal? Will the software alternate between both models (not until now)? Pablo |

I'm not sure why you had to reboot your Linux PC (hung? or other reason), but if CPDN/BOINC was not cleanly shut down, it can corrupt files and cause it to download a new model. Are you running two CPUs or just one? |

Hi Pablo, It's a problem with the way BOINC handles empty or corrupt client_state.xml files when it starts up. BOINC 4.10 will include a fix I submitted to the development team :) In the meantime it's best to close BOINC before doing a reboot. Unfortunately your previous model is now history (but will get reallocated when the server spots it hasn't trickled for a few days). Best thing you can do with it is recover some disk space by deleting its directory, xml file and zip file from the climateprediction.net directory.

Thanks Ian, In fact, I closed BOINC before doing the reboot by killing the boinc_4.09_i686 process. Is that the reason of the files getting corrupted? Is there any "cleaner" way to close the program? Pablo |

Hi, What is the correct way to close BOINC? And yes, I am running boinc in a 2 CPU box, but CPDN seems to use only one (Seti@Home used both when it was the only project running). |

This is what I do. If you are not running it that way, killing the process is about the only way to do it. That shouldn't result in file corruption. You can do a search for "klll" plus "linux" on these boards and see what others are doing in this regard. As for the 2 processor thing, if your General Preferences are set to "use at most" 2 processors, then perhaps your settings for disk space aren't allow enough storage for 2 models? |
