Soft Updates Made Simple and Fast on Non-volatile Memory | USENIX

Mingkai Dong and Haibo Chen, Institute of Parallel and Distributed Systems, Shanghai Jiao Tong University Fast, byte-addressable NVM promises near cache latency and near memory bus throughput for file system operations. However, unanticipated cache line eviction may lead to disordered metadata update and thus existing NVM file systems (NVMFS) use synchronous cache flushes to ensure consistency, wh

NVRAM だと false sharing が無いから Soft Updates 相当をシンプルに実装できて爆速最高という話っぽい(斜め読み)

NVMでSoft Updates大復活!!という感じでおもしろかった・・・
