In this work, we design and implement a Stackable Persistent memory File System (SPFS), which serves NVMM as a persistent writeback cache to NVMM-oblivious filesystems. SPFS can be stacked on a disk-optimized file system to improve I/O performance by absorbing frequent order-preserving small synchronous writes in …
