Good day all. I've been running Seti for year on several machines, all of a sudden on one of them I get this message every day: "Suspicious spike results, host needs reboot or maintenance" ... with no helpful information as to what is causing the problem - rebooting does seem to make it go away, but I shouldn't have to do it every day. Thoughts anyway? Thanks in advance for any help. drc :) |

I'm assuming by "host" it mean the pc the message is appearing on, according to Seti compyters info page on my account it's... ID: 7833758 CPU GenuineIntel Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz [Family 6 Model 158 Stepping 10] (12 processors) GPU INTEL Intel(R) UHD Graphics 630 (3137MB) OpenCL: 2.1 OS Microsoft Windows 10 Professional x64 Edition, (10.00.16299.00) ... does that help? drc :) |

That`s what i imagined. It`s well known that the application for IGPU you are using in that PC is having issues under some circumstances. Also i guess you are utilizing all CPU cores on your CPU which means hyper threading is active. You should either disable HT or reserving 2 - 3 cores to provide enough resources to feed the GPU properly. With each crime and every kindness we birth our future. |

Can you clarify your abbreviations such as IGPU and HT? And how would I "reserve" cores for use by the GPU? drc :) |

Can you clarify your abbreviations such as IGPU and HT? IGPU = integrated graphics processing unit. So this device is integrated in your CPU. HT = Hyper threading. Your CPU has 6 physical cores but shows 12. This means if you are running 12 instances on CPU there are no resources left to feed the GPU. You can reserve cores by just going to Boinc manager advanced view clicking options and choose on multi processors use at most 50%. First of all your processing times will be faster and you have enough resources left for other things. That means your PC will do almost the same amount of work.

IGPU - Intel GPU. The GPU that sits within your CPU and shares a number of resources with it. HT - Hyper Threading Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

I don't see anything labled "Advanced". Under options there's Computing Preferences and on that dialog is a tab labled "Computing" which has 2 edit boxes for setting a percentage - one for number of cpu's and one for cpu time... ... is this the right place? And if so should I set both or 50% or just one of them and if so which one? drc :) |

Set the "Use at most - % of the CPU's" to 50% Leave the" CPU Time" at 100% PS if you can see these values you are already in "advanced view" |

Done. Do I need to restart boinc or reboot the pc to get these changes to take effect? drc :) |

No. You should see in tasks tab that only 7 instances are running. 6 on CPU and 1 on GPU. With each crime and every kindness we birth our future. |
