Is this normal? 0.26 claimed credit, 20K+ CPU time?

I was just checking on my results, when I noticed that I received low granted credits on a few of my WUs because another PC is claiming very low credits (0.26) on every single WUs. Is this normal? Thanks! |

Sounds like a benchmarking problem. You'll notice that the computer in question is listed as having 64 CPUs. But the quorum of results should take care of the credit issue as the low value in the quorum for any one WU should be thrown out and not used in the calculation of granted credit (like here). Could you provide a link to the WUs you're talking about? Help and BOINC documentation is available here. |

Dont know anything of SGI machines but I saw your core client is v. 4.58 and the only place where I found something about it is here. And that post is from 1 Jan 2005. Maybe it's time to compile a new version of Boinc for these boxes. |

It does lower the granted credit a bit, but it isn't a big deal... Although, I whish there was a way to let this user know of the problem. Thanks! |

Undoubtedly that user would be fully aware of the problem. Until BOINC has a better scheme for benchmarking (which is on the design boards now) there is nothing the user can do about it. He's probably not too worried as his 64 cpus are churning through a *lot* of work and each 0.26 claim is being dragged up to a very respectable score in most cases. He's probably quite chuffed :). |

When you have as many credits(555,224.77) as this guy, maybe a little benchmarking problem doesn't really seem like much of a problem at all. Top Computers |
