16Description:	Directory with details of a specific memory tier
17
18		This is the directory containing information about a particular
19		memory tier, memtierN, where N is derived based on abstract distance.
20
21		A smaller value of N implies a higher (faster) memory tier in the
22		hierarchy.
23
24		nodes: NUMA nodes that are part of this memory tier.
