NUMA Distance for Heterogeneous Memory

Abstract

Experience with Intel Xeon Phi suggests that NUMA alone is inadequate for assignment of pages to devices in heterogeneous memory systems. We argue that this is because NUMA is based on a single distance metric between all domains (i.e., number of devices "in between" the domains), while relationships between heterogeneous domains can and should be… (More)
