Radiant: efficient page table management for tiered memory systems
Sandeep Kumar, Aravinda Prasad, Smruti R. Sarangi, Sreenivas Subramoney · 2021
Modern enterprise servers are increasingly embracing tiered memory systems with a combination of low latency DRAMs and large capacity but high latency non-volatile main memories (NVMMs) such as Intel’s Optane DC PMM. Prior works have focused on the efficient placement and migration of data on a tiered memory system, but have not studied the optimal placement of page tables.
