I don't know if this works but there are different venues available also for computing preferences where you set the percentage of CPU cores allowed to be used by Boinc. If you setup the host in LHC to venue Home and set the CPU percentage that matches 16 cores and on the other project you setup the same Host to School with 100% of CPU cores. That could possibly result 16 cores for LHC and the rest on other project. The other project may sometimes block the LHC completely. I don't know if this works or not, you have to try it yourself. |

I don’t think that will work. As I understand it Boinc chooses one set of preferences, either local or from one of the projects and applies that to all projects. Thus, a single host cannot be both home and school, nor can it have 67% and 100% at the same time. |

If it can be the first then it can have the second. A single instance of the Boing client can only have one active profile at any one time - yes, you can have many different profiles set up within the different projects but only one can be active. |

Peter I'm not familiar with LH, or virtualbox, but this post in Boinc memory estimate and LHC Settings seems to be talking about your question. |

Each project has separate project level parameters such as which type of tasks it is to send you - only Einstein knows about Gamma tasks and only LHC knows about Atlas tasks. Then there are the Boinc parameters such as the %CPU to use. These make up your profile and you can only have one active profile at any time. |

Ah, I only set project specific things on their websites. CPU percentage etc is done locally. Seems neater that way. Then your location is the one in you local profile and is fixed for that instance of Boinc on that machine. |

But the location is part of the computing preference that you say you have set to local rather than the project preferences that vary according to project. Regardless of the value you have set on each of the project’s websites the Boinc client will only take note of the one value in the active profile. |

Well it seems to work. So my computer is set to say school, locally. But it still obeys the home settings in say Einstein to not get gravity tasks. Because the type of task is a project level setting, not a computing preference determined by the machines location. |

Use the Combined View to see all your project setting across all venues. Helps clear up confusion about which applications are being selected for each venue. https://einsteinathome.org/account/prefs/project/combined |
