I think it's normal for AMD opteron having 8/16 cores such as magny cours or interlagos. Because it usually has 2 numa nodes in a cpu(socket), numa-node can not include a socket. This type of hierarchy would be natural.
(node03 is Dell PowerEdge R815 and maybe quite common, I guess) By the way, I think this inversion should affect rmaps_lama mapping. Tetsuya Mishima > Ick - yeah, that would be a problem.
