Subject: Lazy NUMA sorting?
Date: Thu, 15 Apr 2004 17:12:11 -0400 [thread overview]
Message-ID: <407EFAAB.7060307@techsource.com> (raw)
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.)
