Posted 27 Jun 2011 by GlennG Post: Removing the planclass item didn't solve it. I am still getting the following errors for some WUs and not others. If you have any other ideas, I don't want to keep rejecting any WUs, because I know that that puts strain on the Milky Database. My only other option would be to put my Linux boxes to other projects.

Is the problem with the client, my app_info, or the WUs themselves? I know the client is old, but it has never given me problems before, and I don't have the ability to update all of the libraries on my three systems to those required for newer clients. Any Ideas? |

No New Work

Posted 24 Jun 2010 by GlennG Post: Using 6.10.18 and 6.10.19, no problems getting work everytime boinc reports finished tasks automatically or manually. The problem is with machines that lost contact with MW enough times during yesterday's outage to cause BOINC to recheck the master file. One of my machines is fine, because it didn't timeout yesterday. All of the rest got into the "Fetching" state, and cannot get out because the <scheduler> </scheduler> information does not appear to be in the new project page. |

(Message 9576)
Posted 2 Feb 2009 by GlennG Post: Travis, Logan is right. The real problems for those of us with fast machines are twofold. 1. The estimated duration for a WU, when it is published by the project is way too long (ex. the older WUs show up at around 22 hours after a reset on my machine) After several dozen wus have completed, the DCF has been reduced to the correct amount, but it is considered too low for BOINC to allow more work. 2. The new set of WUs started last week (I38 & I39) had estimated durations out of line with the other WUs. They were about 25% longer to crunch, but the published duration was about 2x. People weren't seeing problem #1 because we were just above the theshold of the problem until the new WUs drove our DCFs down even lower. My suggestion is that the published duration for each WU be cut by a factor of 10. That way the fast machines will still have reasonable DCF, and older, slower machines can have DCFs greater than 1.0. Also, try to make sure that each new set of WUs have duration estimates in line with other outstanding sets. Glenn |

Posted 14 Jan 2009 by GlennG Post: Petros & Speedimic, The newly released windows apps are causing the following question: What are we doing wrong on the Linux side??? ;-) The windows apps appear to be approx 3x the performance of your best Linux releases. Is the windows compiler that much better? Or were there changes to the source code involved? (Inquiring minds and crunchers want to know!!) Cheers, Glenn |
