DPTree: Differential Indexing for Persistent Memory

Summary: Introduces DPTree, a Differential Persistent Tree for persistent memory that batches DRAM writes and merges them into PM to amortize persistence overhead. Crash-consistent, reduces PM writes by 1.7x–3x versus state-of-the-art, with a concurrent design and competitive reads on Intel Optane DIMMs. (summarized by gpt-5-nano on Feb 09 2026)
