I have a situation than my Boinc cross prject identifier has changed. It happend during WCG servers were gone offline from 30 or 31 of August 2012. So now my Boinc combined projects is separately and as I see another NEW boinc USER withe the same name axists but with only WCG project running.
----------------------------------------I have no idea what happend. How to solve this problem and get the OLD Project ID??  [Edit 1 times, last edit by gio777 at Oct 11, 2012 11:56:04 AM] |

The only thing ever to change the CPID is changing your email address. It has to be *absolutely* identical on all your active project accounts, ideally all in small, but best if using case/lower case made same on all your projects. If it is, there's no reason. You're btw the only that has made a correlation with the August30/31 out [was there?]
----------------------------------------If you want to make double sure and have multiple devices, make sure that one has all your projects attached, active or not. Then select them one by one and in the projects tab of BOINC manager and hit update. If things don't align, repeat 48 hours later (which is how long it can take). edit: Yes there was an outage August 31 [Edit 1 times, last edit by Former Member at Sep 26, 2012 3:10:23 PM] |

You're btw the only that has made a correlation with the August30/31 out [was there?] The email-address is converted to lower-case before saved in the database, so this shouldn't be a problem. But, since WCG isn't using standard web-code it's a possibility this isn't done as it should, so verifying WCG is all lower-case can be important. If you want to make double sure and have multiple devices, make sure that one has all your projects attached, active or not. Then select them one by one and in the projects tab of BOINC manager and hit update. If things don't align, repeat 48 hours later (which is how long it can take). It's important all computers is attached to the project has the oldest account in, since otherwise there's a possibility will have one CPID if computer-A was connected last, while another CPID if computer-B was connected last. Having a single computer attached to all projects wasn't enough for me atleast during the Pentathlon earlier this year...  "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |

"oldest account" is arbitrary as it might not have the "oldest" email address registration in the account info. In principle it's the project that had the first registration with the commonly used email address who's CPID prevails, so if you happen to enter it first on a later project you joined, it's the CPID that got generated at the newer account but with oldest CPID timestamp. In case someone changes email address, not really an outlandish event.
As it stands WCG is older than BOINC world, so WCG rulez ;P |

I have an old boinc node and it was impossiable to connect from this node to connect to the wcg project. I was looking in log files and http file was not found. after that I just detached from this project and connected again from the node again and after that it is running ok. I have several nodes running this project and the problem really occured in 1st of september. Here is the newly created boinc account: http://boincstats.com/en/stats/-1/user/detail/2514011/lastDays
----------------------------------------and thus is my old working boinc acount id: http://boincstats.com/en/stats/-1/user/detail/675 in this links you can see that the "BOINC Cross Project IDentifier" are different. |

BOINCstats does a CPID consolidation across multiple projects, so if you have 2, you're likely to show up as 2 separate records over there. If your node is attached to the same account at WCG, but not to the others projects, then your node will not be merged to the oldest CPID you have, which apparently is not at WCG.
Anyway, refer to previous replies. Your WCG clients must at the very least also be attached to the [oldest] project account you have where you first used the email address as that will be the prevailing one. That oldest project does not have to be active [can be set to no work fetch], but has to connect a few times to said oldest project and WCG to establish who's got the oldest CPID generated for that email address. Ones that's done WCG will pick up and be merged back at BOINCstats. |

It's really a case of getting any client you still have running [with your oldest account/email registration] to also be attached to WCG, so the client can figure out which preferred CPID needs to be assigned to WCG.
You'll find your CPID on My Grid > My Profile. Not aware how you could manually change this as it's computed from the email address, with some encoding to prevent people finding out what your email address is from the CPID. If the email address is correct per the checks we gave you in previous replies, than there's no manual way to change it... the CPIDs should align automatically. That said, send mail to support what your CPID should be, guess it being 1ddb228b93d6ec749b45fc0e9a546770 Maybe they can force it in, but it to me not right to do that. The clients should organize that on their own. |

In principle it's the project that had the first registration with the commonly used email address who's CPID prevails, so if you happen to enter it first on a later project you joined, it's the CPID that got generated at the newer account but with oldest CPID timestamp. In case someone changes email address, not really an outlandish event. Users changing email-addresses isn't uncommon. But, the problem with your logic is this: 1: <cross_project_id> has both an "internal" and an "external" part, where "internal" is used by BOINC-client while "external" is shown on projects web-page and is included in stats-exports. 2: The external is generated based on "internal" + email-address. 3: The "internal" <cross_project_id> is independent of email-address. 4: If you looks through client_state.xml you'll quickly see the <cpid_time> for a project is exactly equal to <user_create_time> for this project and this again equals the time you made this account on the project. Changing the email-address does not change the <cpid_time>. #3 can easily be verified by checking your scheduler-replies. While the <email_hash> changes every time you changes your email-address, the <cross_project_id> is the same. "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |
