So, I understand that the 2.6 SMP balancer redistributes workload on a periodic basis. Once every second or something, it migrates processes.
A NUMA system would have to do something similar, where if there is a page which is referenced by only one process, and the page is located on the "wrong" node, it could be migrated. This could be done gradually by a periodic background process. Is this already how it works?
Also, if a page is being referenced by multiple nodes, the same background process could make mirror copies. (Age of page would be an important consideration here so moves don't happen for short-lived pages.)
