I confirm that now they are not limited to 1 thread, however now the behavior of the 4t task is the opposite : they are actually using 8 threads ! WTH ? |

Yes, 4t now meams, that you need at least 4 cores. The wu uses all cores. . |

Oh OK, so it changed then : I think that before I could have 2 parallel 4t tasks running on my i5 / 8 threads. Good to know this is normal :) |

Does that mean this app_config is no longer needed? <app_config> <app> <name>yafu-4t</name> </app> <app_version> <app_name>yafu-4t</app_name> <plan_class>4t</plan_class> <avg_ncpus>8</avg_ncpus> <cmdline>--nthreads 8</cmdline> </app_version> </app_config> Also why does show graphics always display 100%? |

Yes, 4t now meams, that you need at least 4 cores. The wu uses all cores. So what does that mean when I choose to do the 8t tasks and choose this in the settings? Max # jobs 8 Max # CPUs 4 Does it mean it won't work or just take longer to run them? |

I think it 8 cores is minimum for 8ttasks. This means that if you set 4 cores in settings you will not get 8t tasks. |
