CPU pinning GUI has no effect

[golli53]

If I try to select new pinning options or deselect old ones and hit APPLY or DONE, nothing seems to happen. No errors come up and nothing new in the log, so it appears to be successful. But the settings are the same as the old ones when I go back to the page.

 

I'm using version 6.8.3

Is there a way to change these settings from the shell?

 

Still not working through GUI. Restarted and still have the same issues. I also tried disabling VMs as my interest is changing the docker pinning, but still no cigar.

Thanks! I played around with this and am getting another problem unfortunately. If I set 10 containers all to "3,4,10,11", I get 100% usage on CPU 3 and 0% on 4,10,11. Those 4 CPUs are all isolated.

Expected behaviour.  Once you isolate cores you are isolating them from the OS, so effective the task context switcher won't operate on those cores. 

 

What this means is that if you pin a container to multiple isolated cores, it will only execute on a single core.  Isolated cores are really for VM use
