For some reason my 2.2Ghz Xeon is detected as a 2.2GHz Pentium 4. Is there any way to fix this?

As far as I know, that's because your Xeon is a Pentium 4. The only significant difference between a P4 and a Xeon is the cache. I think.
Anyway, it makes no difference to BOINC or WCG. Don't worry about it. |

Do you use the standard (UD) client, or BOINC?
----------------------------------------BOINC uses all processors and cores available if you want. UD can only use 1 core. Further BOINC uses the benchmark score to claim a certain number of points, even if your monster-machine would be recognised as a P1 60MHz, your benchmarks would be massive and you would still claim all the points that you would expect from your Xeon.   |

Snip:if your monster-machine would be recognised as a P1 60MHz, your benchmarks would be massive and you would still claim all the points that you would expect from your Xeon. Does this type of thing actually happen? I realise this is an exaggeration but could be significant in light of the new point system See BOINC POINTS in Member News. We have been evaluating this data. There are two key observations that match what the members have found. 2) About 5% of results claim points significantly in excess of the average for their platform. So I read from this that your reported platform is now taken into account to determine outliers. Cheers. ozylynx  |

No, that's not how it works. Each work unit should get the same score whatever computer it runs on. A computer with a massive benchmark should complete the work unit in a fraction of the time, and still claim the normal amount.
The comment about platforms refers to the way work isn't shared in the same quorum between Windows, Linux and Mac. All copies of a work unit will be sent to the same platform. This means that the present correction to the points system isn't affected by the Linux/Windows benchmark discrepancy. On the other hand, it does nothing to correct that issue, either. We must wait for the next BOINC version for a solution to that. |

Cheers. ozylynx What Didactylos says (see below) is exactly what I was trying to say. Sorry for my bad way of explaining, English is not my native language you know....  No, that's not how it works.
