I used to live about a wavelength from a commercial 10kW AM band radio transmitter. Everything was hot! Of course powerline likes to get into everything too. Sometimes it is easier to shield the powerlines or move them away from the equipment or orient them at right angles to the data cables. I also remember something recent about the power being redone near the lab building. Check on the timeframe of when the problem started and when that work was done. Perhaps some powerline got moved too close to the data cable maybe even on another floor of the building. New construction might be ENT rather than EMT. Or they could have induced a ground loop in the construction or worse not tied something to ground that should be. Finally, despite the name Fibre Channel, not all Fibre Channel is carried on fibre optic cables. Copper cable alternatives are available on short runs by some vendors. I suppose if the 2 interconnected pieces of equipment were not on the same ground bus there could be some differential between them thus inducing some current flow from one to the other. |

Something is still messed up From the log of one of my machines 10/7/2007 1:07:03 AM|SETI@home|Scheduler RPC succeeded [server version 511] 10/7/2007 1:07:03 AM|SETI@home|Message from server: No work sent 10/7/2007 1:07:03 AM|SETI@home|Message from server: (won't finish in time) Computer on 85.4% of time, BOINC on 100.0% of that, this project gets 100.0% of that Say What ?? the machine is on 24/7 and only runs seti@home The closest deadline is 0ct 30 for 6 less than 5.5hr chunks everything else is not due till Nov. Unless the scheduler is messed up and is ignoring deadlines the oct deadlines should be completed early monday. So WHY the won't finish in time and computer on errors ??? |

Hi, Something is still messed up Your WUs will finish in time. But Berkeley thinks that the new WUs Berkeley wants to send to you won't be reported in time. At the moment, VHAR workunits with a deadline of about 8 days are sent out. Some of your machines have average turnaround times of 8 to 10 days, which are too long to report the WUs in time. That's the reason why Boinc blocks you from getting new work. Regards, Carsten |

Something is still messed up Have you recently (within the last 2 months) shut that machine down for any reason? (maintenance, a reboot, anything?) That would cause the "Computer on" stat to fall below 100%... . Hello, from Albany, CA!... |

08/10/2007 13:49:01||Access to reference site succeeded - project servers may be temporarily down. arr25b, does the estimated time to finish a WU match with the real time? It can happen that the client_state.xml file gets corrupted. SETI@Home calculates the need for new WUs on basis of the estimated time to finish your backlog. You can repair this by editing the client_state.xml file. Open it in any Text Editor and search for "duration_correction_factor" This will give results like this: <duration_correction_factor>0.368199</duration_correction_factor> Make sure it is the one for SETI! If estimated times are longer than real crunch time then reduce the correction factor. Make sure you use the exact same number of decimal places!!! Safe it and restart BOINC. |

08/10/2007 13:49:01||Access to reference site succeeded - project servers may be temporarily down. I'll give that a try,I have also altered my days buffering from 10 to 7,still can't d/l any wu's even on a fresh install |

No. We're talking about converting electrical signals to light, running them through the fiber optics, and then converting from light back to electrical signals. The signal is referenced to local ground at the converter at each end. That's one of the best things about fiber optics, all of the yucky "what is ground" questions go away. The light is light at each end of the cable. |

I suppose if the 2 interconnected pieces of equipment were not on the same ground bus there could be some differential between them thus inducing some current flow from one to the other. ... and this is the other reason you use optical fiber -- it's a great way to break up ground loops (earth loops) caused by the cable ground lines. |

Hi, That was from a machine that returns a result in about 8 hours The whole queue would be returned in 8-10 days |

The seti@home - Server actual very unstable! SETI@Home runs on old, hand-me-down hardware. That's why BOINC is designed to tolerate outages. You can:
