I was checking the Work tab in my BOINC Manager and saw that two WU's, an Einstein and a LHC, were running at the same time.

> Can someone tell me if they are both corrupted now? They shouldn't be. This is an elusive BOINC issue that crops up from time to time. The only harm done should be slower processing due to the science apps fighting for CPU cycles. |

It happened also to me. Results were OK, CPU time was just divided for both applications, so it took longer time to complete WUs. I restarted BOINC and everything was normal again afterwards. |

Is this a self-correcting issue? Meaning, after the 60 minutes of crunching both WU's does it then go back to crunching only 1 or does it continue to cruch 2 at a time? Jim > It happened also to me.

This is the 'normal' behaviour if you have more than one project. At Switch time all activity is suspended and the next project gets the processor. If you have 'even weighted' projects (i.e. each project with '100') then Boinc will switch the projects every hour. Udo |
