FUR: Fast and Unlimited Reads on Persistent Memory Transactions

Despite the recent improvements in supporting Persistent Hardware Transactions (PHTs) on emerging persistent memories (PM), they have largely overlooked the poor performance of Read-Only (RO) transactions, which suffer from two crucial bottlenecks: i) the considerable post-commit delays required to ensure consistency with concurrent update transactions; and ii) the well-known tight read capacity limits of the commercially available HTM implementations.
