Our architecture has blades with two Nehalems on them, and the blades
are connected together in a CC-NUMA fashion. Each Nehalem shows up as a
Node and the blades show up as Miscs. I plan to use hwloc to facilitate
different patterns for striding the placement of processes.
In one pattern I might want to place processes on all the Cores in a
Misc and then move to the next Misc. A topology tree that looks like
System -> Misc -> Core makes that easy. Having Nodes in there just adds
unneeded complexity.
Feel free to come up with a cleaner patch. :)
