Understanding the Idiosyncrasies of Real Persistent Memory

Summary: PMIdioBench exposes and categorizes counter-intuitive behaviors of real Optane DCPMM, overturning common PMEM performance assumptions. The study distills technology-agnostic guidance for NUMA data placement and lock-free structures under eADR and ADR. (summarized by gpt-5.6-luna on Jul 24 2026)
