Understanding Application Recomputability without Crash Consistency in Non-Volatile Memory
Jie Ren, Kai Wu, Dong Li · 2018
Emerging non-volatile memory (NVM) is promising to be used as main memory, because of its good performance, density, and energy efficiency. Leveraging the non-volatility of NVM as main memory, we can recover data objects and resume application computation (recomputation) after the application crashes. The existing work studies how to ensure that data objects stored in NVM can be recovered to a consistent version during system recovery, a property referred to as crash consistency. However, enabling crash consistency often requires program modification and brings large runtime overhead.
