From Filesystem Designer to Persistent Data Structure Designer: Enabling Safe Memory Management for Byte-addressable NVRAM




Abstract: We present two building blocks that allow applications to manage fast persistent memory placed on the memory bus, without special hardware support: (1) a new memory allocator (NVMalloc) designed for wear leveling and whose metadata is robust to accidental corruption, and (2) an asynchronous mprotect primitive that allows applications to protect persistent in-memory data against spurious updates without incurring the overhead of synchronous memory protection.
