Design and implementation of bandwidth-aware memory placement and migration policies for heterogeneous memory systems
Seongdae Yu, Seongbeom Park, Woongki Baek · 2017
Heterogeneous memory systems that comprise memory nodes based on widely-different device technologies (e.g., DRAM and nonvolatile memory (NVM)) are emerging in various computing domains ranging from high-performance to embedded computing. Despite the extensive prior work on architectural and system software support for heterogeneous memory systems, relatively little work has been done to investigate the OS-level memory placement and migration policies that consider the bandwidth differences of heterogeneous memory nodes.
