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 !

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%?

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.
