Occasional overheating fix (echo "0" ... > online)

Unread post by Ronaldleess » Tue Aug 13, 2019 10:52 pm

I love my XU4, let there be no confusion about that! But occasionally it will overheat during extended Blender runs. Yes - I know blender will take every core and max it out. So I use the "echo "0" ... > online" bit to remove some processors from the mix. This works pretty well. I usually reduce the processors to all of the little ones and one or two big ones. Sometimes though - it seems the "echo "0" ... > online" bit does not take hold. Is this a known issue? Occasionally this technique does not work even if I repeat it several times before launching Blender.

You shouldn't turn cores on/off like that. They are managed by the governor.
If you want to have a process run on specific cores you need to look at taskset or cgroups with cpuset.
