Hi - I recently added SETI to my BOINC manager. Unfortunately, when SETI starts to run, including the GPU tasks, a kernel_task in my system goes crazy, using all the CPUs and leaving SETI with next to nothing. I also run Asteroids and it does not do the same thing - it uses over 90% of the CPUs. Any ideas out there? Thank you, in advance. |

By default BOINC (and thus SETI) will attempt to use all your CPU cores and GPUs. You can restrict the number of CPU cores BOINC uses fairly simply: In the manager go to "advanced" view, then select "computing preferences" and reduce the % to give a whole number of cores used - for example if you have a 4 core CPU and only want BOINC to use 2 of them set to 50%. This can get a bit tricky when trying to drop say 1 core on a 12 core CPU - a bit "guess and tune" may be required to work out exactly what the rounding is doing (we all know what it should be doing but....) By default a single GPU task will attempt to use 100% of a GPU's compute capability. It is much harder (almost impossible) to effectively reduce this from the user interface but it can be controlled using various configuration files - not for the "novice". In my experience Asteroids is not as demanding on processors as SETI, so your observations don't come as a surprise.

Hey Bob - Thank you for that. I don't use my computer much, so I like to let BOINC use as much as possible, and when when I want to use the computer, I suspend the projects. But that doesn't seem to help. Seeing as how I want to let the projects use as much of the CPUs as possible, do you have an recommendation on settings? Btw - I am on Mac 10.11.6. I just changed my Preferences to "Suspend when computer is in use" but that doesn't seem to have much effect. |

After you changed the preference setting, did you go to the Activity menu and select the "Use X based on preferences" setting for the CPU and GPU? ... and still I fear, and still I dare not laugh at the Mad Man!

I had them both set to "run always." Made the change you suggested and that seems to do the trick! Thank you. I see that you're Queen fan - go to www.MichaelMastro.com and go to the Music Photography Gallery. There might be somethings there you enjoy. Thanks, again. |

:) Looks to be photos from the "Day at the Races" tour. Thanks |
