Language runtime support for NVM/DRAM hybrid main memory

Abstract

Replacing of DRAM in main memory with non-volatile memory (NVM) has several merits. However, NVM under development has some limitations in write operation. To overcome it, some previous researches proposed NVM/DRAM hybrid memory architecture. In the architecture, it needs to determine data placements between NVM and DRAM. In this paper, we advocate that programming language runtimes are useful for management of NVM/DRAM hybrid main memory. In addition, we will propose a method to manage NVM/DRAM hybrid main memory with language runtime support.
