4.5.1 Sampled Exclusivity and Policy Selection
To determine which page migration policy should be a
applied to a certain page p, we calculate the sampled exclusivity
Exclsample of the page, as shown in Equation (3), where
NVp is the NUMA vector of page p, N is the total number of
NUMA nodes in the system, and the max function returns
the maximum value of its argument. Pages with a high exclusivity
are accessed mostly from a single NUMA node and are
therefore more suitable for locality-based mapping
