Modularising Verification Of Durable Opacity

Non-volatile memory (NVM), also known as persistent memory, is an emerging paradigm for that preserves its contents even after power loss. NVM widely expected to become ubiquitous, and hardware architectures are already providing support programming. This has stimulated interest in the design of novel concepts ensuring correctness concurrent programming abstractions face persistency development associated verification approaches. Software transactional (STM) a key abstraction supports access shared state. In fashion similar linearizability condition data structures, there established notion STMs opacity. We have recently proposed durable opacity natural extension setting with non-volatile memory. Together this condition, we designed technique based on refinement. paper, extend work two directions. First, develop durably opaque version NOrec (no ownership records), existing STM algorithm proven be opaque. Second, modularise our approach by separating proof durability accesses from For NOrec, allows us re-use complement it
