Compiler and Architecture Support for NVM Crash Consistency
In this talk, I'll present two hardware/software co-design approaches to nonvolatile memory (NVM) crash consistency, i.e., ReplayCache and PMEM-Spec. ReplayCache enables volatile cache for single-core nonvolatile processors of batteryless energy-harvesting systems where NVM serves as the main memory.
On the other hand, PMEM-Spec targets multi-core general-purpose processors with deep cache hierarchy and a hybrid of DRAM and NVM.
I will demonstrate how computer architecture and compiler can work together to guarantee NVM crash consistency in a cost-effective way.
Keywords: Compilers, Computer architecture, Nonvolatile Memory
