Hash Map Consistency Across Configurations

Hash maps are consistent across configurations that have the same number of hash buckets. Any two systems having the same number of AMPs and hash buckets also have identical primary hash maps. Fallback hash maps often differ somewhat from system to system depending on how their AMPs are clustered and on their development across time.
