Following up on this (sorry for off topic):
You mentioned also that the successor to numad was automatic numa balancing via kernel
facilities.
However I did not find any meaningful documentation how this is exactly done or how this
can be tuned, if at all.
I found the general overview here, which gives a good general introduction to numa but not
how auto placement works:
https://www.kernel.org/doc/html/latest/admin-guide/mm/numaperf.html
I found also
https://www.kernel.org/doc/html/latest/admin-guide/mm/numa_memory_policy....
which talks about possible memory policys at greath length but also doesn't go into
the topic of auto balancing.
At least numactl is mentioned which can be used to manually tweak the memory policy, but I
don't know how that would
interfere with some automagic placement?
Am I missing something or is there no documentation on how the kernel handles this?
Thanks in advance for any pointers!
