On my PC with 12 cores 24 threads, I can max out 64GB if there is too many ATLAS tasks. I have set cpu and tasks to no limit to try fix this issue I'm having... doesn't seem to be working :( |

On my PC with 12 cores 24 threads, I can max out 64GB if there is too many ATLAS tasks. removed <project_max_concurrent>1</project_max_concurrent> all fixed :) |

On my PC with 12 cores 24 threads, I can max out 64GB if there is too many ATLAS tasks. Is there a magic way to make Bionic preference the Atlas units over Sixtrack? |

dissable sixtrack in project preferences |

You got trapped in 2 pitfalls. 1. sixtrack is also a subproject of LHC and therefore affected by the <project_max_concurrent> setting although it is not mentioned in your app_config.xml But you managed it as you removed the <project_max_concurrent> entry. 2. You may check more than one subprojects in your preferences but you are not able to influence which of them sends WUs to your host. Together with the "unlimited" setting your host is now flooded with WUs. Until you have a clear picture of how many multicore ATLAS WUs you are able to run concurrently you may not check another subproject. |

You got trapped in 2 pitfalls. 1, I have never used the max_concurrent till this post. 2, Ah, that's a bit of a shame :( I can honestly say I have never had so many tasks download at once! it seems with the following I can run 4 tasks, 5th needs slightly more ran :( <app_config> <app> <name>ATLAS</name> <max_concurrent>4</max_concurrent> <fraction_done_exact/> </app> <app_version> <app_name>ATLAS</app_name> <plan_class>vbox64_mt_mcore_atlas</plan_class> <avg_ncpus>2.0</avg_ncpus> <cmdline>--memory_size_mb 4800</cmdline> </app_version> </app_config> |
