Linux Persistent Memory
LPSM is a C library with a simple interface that manages a segment of memory backed by a persistent file. It differs from ordinary mmap() in two ways: it can optionally offer heap management (malloc/free/realloc) within the arena, and more importantly, a transaction log is used to ensure the consistency of the persistent representation. The application notifies LPSM whenever the arena is in a consistent state, suitable for checkpointing. If the application or system crashes, the arena will always be recovered to a consistent checkpoint.
