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.html 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! -- Mit freundlichen Grüßen / Regards Sven Kieske Systementwickler Mittwald CM Service GmbH & Co.
