Hi,
A few weeks ago I installed the new version of boinc on my two crunching computers (two athlon x2s). Both computers continued to compute WUs at their normal rate until late last week/early this week. Now boinc will only use one CPU core and in fact only finds a single cpu core when it runs benchmarks. Anyone know what I can do to solve this problem? Thanks, Josh |

Hello JoshuaBarnes,
Sounds like a puzzle. Please post the start of your Messages tab after a reboot so that we can see this for ourselves. Lawrence |

Hi lawrencehardin,
It certainly is a puzzle. Here is the message which was posted to me when my computer first encountered the problem. 27/04/2009 9:28:44 PM||General prefs: from World Community Grid (last modified 27-Apr-2009 08:12:15) 27/04/2009 9:28:44 PM||Computer location: home 27/04/2009 9:28:44 PM||General prefs: using separate prefs for home 27/04/2009 9:28:44 PM||Preferences limit memory usage when active to 1534.85MB 27/04/2009 9:28:44 PM||Preferences limit memory usage when idle to 1841.82MB 27/04/2009 9:28:44 PM||Preferences limit disk usage to 90.63GB 27/04/2009 9:28:44 PM||Number of usable CPUs has changed from 2 to 1.

I had thought that one of the cores mealy burned out from running at 100% for weeks on end with only stock cooling. However, with the re-occurrence of the problem in this PC it leads me to believe it may be a software glitch. Thanks for your hep thus far! |

Check your "home" device profile and make sure that you have
----------------------------------------On multiprocessors, use: 100 % of processors. If this is OK go to the Advanced view of BoincMgr and select Advanced->Preferences. There you will find the same parameter in the "Processor usage" tab. It must be 100 % there too. If you don't need to use Local Preferences for other reasons you may simply click the "Clear" button in the top right corner and rely exclusively on your "home" profile. Cheers. Jean. |

The last time someone had this identical problem, they had failed to note that they recently changed their WCG preferences.
This caused an issue with the latest BOINC version. The details are confusing, so I will omit them. JmBoullier has given the steps to resolve this. |
