Ah, okay, so there really is no requirement for a newly coming up cpu to be on a specific node. > distributing the memory to several nodes in order to avoid a single huge > node. So that should be sort of ok. Sounds good to me. If that's the only purpose, we don't lose much by round-robining the possible CPUs on boot and sticking with the mapping. Thanks. -- tejun
