I noticed LHC assigned me a different CPID than the other three BOINC projects I work with. I've read that there is a mechanism to resolve this automatically over time. I joined LHC July 15th - so perhaps there hasn't been sufficient time elapsed to have this happen. |

You get a new CPID when you sign up for a new project. It will then be communicated to the other projects when your client gets new work from those projects. Chrulle Research Assistant & Ex-LHC@home developer Niels Bohr Institute |

To get the CPIDs for all of the projects to line up, all of the following must happen / be true. 1) The email addresses must be identical including case as they are hashed with the internal CPID to generate the external CPID without a change of case. 2) There must be a path from project server to host to project server that covers all projects. Example: Machine A crunches S@H and Machine B Crunches Einstein, these are two distinct pools, and the two CPIDs will not ever line up. However if both crunch LHC as well, then the CPIDs will eventually line up. 3) There must be a communication of the CPID from a host that has the correct CPID to every project server. 4) The project servers must have recent enough code. (Only Crash Collection does not as far as I know). 5) The projects must export the stats XML. 6) The stats site must import the stats XML. What the new CPID changes to depends on the version of the BOINC client. in 4.19 and earlier, the CPID chosen is the numerically larger. In 4.20 and later, the CPID chosen is the one from the project that has the earliest join date. BOINC WIKI |

Just to be clear, I have Machine A which participates in four projects, including LHC, and Machine B which participates in only two, and does not participate in LHC. All projects are running BOINC 4.43 or 4.45. (Seti, Einstein, Predictor and LHC). Seti was my first joined Project, LHC my last. Three projects have the CPID of e5b1086f050ab1789965c8ba1b427e79 LHC has a CPID of 4d41b680376b4ce8e5a86b4bee646f34 |

If so, is your email exaclty the same on all of the projects? I wonder if LHC is using server software that is old enough to still require fullfillment of any work request before things like updating preferences and CPIDs takes place. This is a bug that was fixed a few months ago, but may not have made it to all of the projects yet. BOINC WIKI |

The Project ID's on both machines are the same, EXCEPT for LHC LHC is not running on Machine B |

Is the email address exactly the same, including case, for LHC as for the other projects? BOINC WIKI |

I have the same problem: first i entered seti@home -> cpid 1 then i entered einstein@home -> cpid 1 then LHC@home -> cpid 2 :-( there are 3 machines running all of the 3 projects. first there were 2 doing all 3 and one that did only seti+einstein. after reading this thread i changed to similiar config on all 3 machines, but the cpid 2 does not turn magically into cpid 1... :-) is there an administrative way to change the cpid?? |
