I know I've seen this somewhere but I just can't find it, so apologies in advance. I want MW@H to use no more than, say, 5 of my 12 CPU threads, and I know I have to set a value in a config file in the project's directory, but what, and which file? I don't want to apply the same restriction to all 8 of my projects. Rgds Peter. |

It is an "app_config.xml" file, placed in the project directory. This one is set up for 2 CPU cores per work unit, and a maximum of 3 work units. Also, the "fraction_done_exact" entry improves the accuracy of the estimated time. <app_config> Note that you need to read the file to activate it. One way is to restart BOINC, or reboot, or use "Read config files" in the BOINC Options menu. |

That's what I needed to know - thank you. Wouldn't it be good if there were a central place where all the config options were documented. Rgds Peter. |

Have a look at https://boinc.berkeley.edu/wiki/Client_configuration It doesn't provide lots of examples(!) but there's a lot of information there. Cheers - Al. |
