What's the best way, very specifically, to transfer un-crunched WU from one machine to another? Thanks, Russ Proud member of the half bill club! |

I think BOINC is specifically designed against that. I know you can't easily transfer work between machines. |

The easiest way is probably: 1. Install BOINC on the new machine. 2. Close/exit BOINC on the new machine. 3. Close/exit BOINC on the old machine. 4. Copy the contents of the data folder from the old machine to the new one. Note: The location of your data folder can very depending on the OS. 5. Start BOINC on the new machine. 6. Crunch...

The easiest way is probably: Even easier than that. Since BOINC's uninstaller is non-destructive, you can do it like this: 1. Uninstall BOINC on old machine. This leaves behind the data directory where all workunits are stored. 2. Move data directory to the new machine. 3. Install BOINC on the new machine and make sure the installer points to the correct data directory (if it isn't the default) BOINC will automatically pick up where it left off. Note that if you were using optimized apps, you may want to look into re-installing if your new machine supports a newer/better instruction set. |

What's the best way, very specifically, to transfer un-crunched WU from one machine to another? You can transfer the identity of a machine to a different machine, including un-crunched work. If you have a slow machine with tons of work, and a fast machine that is empty, you could actually swap identities. What you can't do is take some work on machine "A" and give it to machine "B." One form of widespread cheating in SETI Classic was to have one machine download work, crunch it on multiple machines offline, and then give it back to the original machine to return -- making that original machine seem mind-bogglingly fast. |

Thanks for the feedback. Half wrong, half right. Can't get WU's to be used in new directory. BOINC tasks doesn't see them. How do I change the identity? Thanks! Proud member of the half bill club! |

What's the best way, very specifically, to transfer un-crunched WU from one machine to another? I used to do this, not to cheat but because machine "A" (at work) had internet access and machine "B" (at home) didn't. I never realised it was considered cheating or that anyone was looking at the performance of machine "A". Brian. |

sharing WU's is no longer viable since your machine will eventually want to return the work and you can't have 2 machines with the same ID In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

I never realised it was considered cheating or that anyone was looking at the performance of machine "A". I don't think this was ever considered as cheating. What I can remember is that some people ran a task on one pc up to 99%, than distribute that task to multiple machines and let those machines finish the last % and return the result. And that was cheating... Seti@Netherlands website |

Wouldn't the machine just realize it can't use the old WU's an abandon them? You know clientID and all. Maybe if you did the merger clients thing BEFORE you load them up. Traveling through space at ~67,000mph! |

Thanks for the feedback. Depending on what state BOINC is in now you can either do a project detach/attach or just remove BOINC and reinstall it. Then attach to the project. If you still have the data from the old machine intact you might be able to try again. If BOINC aborted the tasks on the new machine then you are out of luck.
