I have 32 logical cores cpu nad had 2 yafu task running 8cpu + 8cpu so half of cores were not utilized. Selected to receive YAFU-16t tasks and I got one YAFU-16t waiting to run on 32 cores !
Wunderfull.
So I had to delete that task, set usage limits to 50% in boinc manager preferences and ask for task again and then set it back 100%.
Hopefully I got what I wanted and my cpu was 100% utilized (not most of time of course but sheduled to).
But I don't uderstand why yafu scheduller selects cores this way. Simillary I cannot choose in yafu project preferences cpu limit higher than 8 cores what is quite outdated and I have always got 3*8cpus tasks on 32cores cpu. And nothing more when cpu limit is set to 8cpus.

You can always choose 'no limit' but yes if decide to limit the cores 8 is the highest and yes it needs to be updated to 32, though maybe not every number in between 8 and 32

You can choose now up to 32 CPUs.

Is it possible to upgrade yafu from 1.34 to 2.10?

Yafu 2 displays estimated time to completion for gnfs in factor.log unlike 1.34
