Home many SETI fikles can I crunch at a time using BOINC? <img src="http://boinc.mundayweb.com/one/stats.php?userID=1052&prj=1&trans=off"> <img src="http://seti.mundayweb.com/stats.php?userID=749&trans=off"> |

> Home many SETI fikles can I crunch at a time using BOINC? One per CPU. Crunching more than one is actually a little slower (due to the time it takes for the OS to do context switching). |

Right now my computer is doing 2 at a time but I did not set it to do it that way? <img src="http://boinc.mundayweb.com/one/stats.php?userID=1052&prj=1&trans=off"> <img src="http://seti.mundayweb.com/stats.php?userID=749&trans=off"> |

How can I set it to do more or less SETI files at a time? I am only running SETI on BOINC! <img src="http://boinc.mundayweb.com/one/stats.php?userID=1052&prj=1&trans=off"> <img src="http://seti.mundayweb.com/stats.php?userID=749&trans=off"> |

You need to change your Preferences on Your Account at the SETI site to tell it NOT leave the application in memory.

You have a P4 3.0G HT processor. HT processors look like 2 virtual processors, and you will run 2 simutaneously, if you leave Seti at default options. My movie https://vimeo.com/manage/videos/502242 |

> I am running Windows XP SP2 > How can I set it to do more or less files? You can specify how many processors to use under Your account - General preferences. Choose edit and the on the line "On multiprocessors, use at most" specify a number... |

As Holmis mentioned, you can go into your account settings and tell it to only use 1 CPU on multi-CPU systems. That will tell BOINC to only use one of your 2 virtual CPUs, and so only use about 50% of your hyperthreaded CPU. I hope that helps...hyperthreaded CPUs are a little confusing at first, but they are quite good at doing 2 SETI WU's at the same time--about 30% better throughput than without hyperthreading. |

Is there anyway to do more than 2 at a time? <img src="http://boinc.mundayweb.com/one/stats.php?userID=1052&prj=1&trans=off"> <img src="http://seti.mundayweb.com/stats.php?userID=749&trans=off"> |

> Is there anyway to do more than 2 at a time? Have 4 CPUs (real or virtual). Or 8, or 16, or 32, or 64 etc. Grant Darwin NT |
