PASTE: A Network Programming Interface for Non-Volatile Main Memory
summary
PASTE exposes a network API that lets NICs DMA directly into NVMM, so packets land persistently without copies and without kernel syscalls. Measured persistence drops from about 1.3 ms (SSD) to ~2 µs, and copy-avoiding I/O yields large throughput gains for 1.2 KB writes while 64‑byte writes show little change. The team implements a write-ahead log and a B+ tree on NVMM and ports Redis, pKVS and a software switch logger, showing practical end-to-end speedups; PASTE is a netmap branch.
