Hello, Set your "use at most xx % of processors" to 75%. Under preferences and ditch the <ncpus> in cc_config. ____________ BOINC blog | |

This won't work tho, because when I'll suspend GPUgrid, BOINC will only use 3 CPU for WCG. | |

When did you run these tests? 3+1 was indeed better than 4+1 with reasonably fast GPUs.. with the old clients <6.60. I think it was in Jan 09 when we got the new clients with massively reduced cpu usage under windows and for these the was almost no performance drop going from 3+1 to 4+1. Differences of a few % are difficult to measure anyway due to the natural fluctuation in runtimes and due to the different WUs. | |

your system should be able to run 5 wu's.... | |

His point was that at 4+1 the gpu gets slower than at 3+1, which quickly offsets any gains from the additional core. However, as I said above, this information may be outdated.. so please, noone panic right now ;) | |

I did tests at the end on january yeah, so they might be a bit outdated. Well I'll retry 3+1 vs 4+1 and see if anything changed :) Thanks :p | |
