Is there any way to limit the number of units that can be run at the same time? at the moment it's downloading a load and running up to 32 at a time which is causing the machine to grind to a halt forcing me to reboot which then causes a lot of the tasks to fail. I have tried the following config but no joy <app_config> <app_version> <app_name>Theory</app_name> <plan_class>vbox64_mt_mcore_theory</plan_class> <avg_ncpus>16.0</avg_ncpus> </app_version> </app_config> |

You can testing this parameter: <max_concurrent>x</max_concurrent> |

Just an example: <app_config> <project_max_concurrent>3</project_max_concurrent> <app> <name>ATLAS</name> <max_concurrent>1</max_concurrent> </app> <app> <name>CMS</name> <max_concurrent>1</max_concurrent> </app> <app> <name>Theory</name> <max_concurrent>1</max_concurrent> </app> <app_version> <app_name>ATLAS</app_name> <plan_class>vbox64_mt_mcore_atlas</plan_class> <avg_ncpus>4</avg_ncpus> <cmdline>--memory_size_mb 4096 --nthreads 4</cmdline> </app_version> <app_version> <app_name>CMS</app_name> <plan_class>vbox64</plan_class> <cmdline>--memory_size_mb 2048 --nthreads 1</cmdline> </app_version> <app_version> <app_name>Theory</app_name> <plan_class>vbox64_theory</plan_class> <avg_ncpus>1</avg_ncpus> <cmdline>--memory_size_mb 768 --nthreads 1</cmdline> </app_version> </app_config> Be aware that app_config don't have influence how much tasks are downloaded from the server. You have to reduce that with the buffer setting with BOINC Manager. |

Cheers, that will teach me to troubleshoot before caffeine, ill see how I get along with it. Does anyone know why loading up 32 VM Theory tasks lags out the PC? I saw an old thread from 2020 about it but couldn't see a resolution. |

My system also was grinding to halt with virtualbox. I had to use vmware workstation linux vm to run lhcathome. |
