Abstract

This paper addresses the challenges of coupling byte addressable non-volatile memory (NVM) and hardware transaction memory (HTM) in high-performance transaction processing. We first show that HTM transactions can be ordered using existing processor instructions without any hardware changes. In contrast, existing solutions posit changes to HTM mechanisms in the form of special instructions or modified functionality. We exploit the ordering mechanism to design a novel persistence method that decouples HTM concurrency from back-end NVM operations. Failure atomicity is achieved using redo logging coupled with aliasing to guard against mistimed cache evictions. Our algorithm uses efficient lock-free mechanisms with bounded static memory requirements. We evaluated our approach using both micro-benchmarks, and, benchmarks in the STAMP suite, and showed that it compares well with standard (volatile) HTM transactions. We also showed that it yields significant gains in throughput and latency in comparison with persistent transactional locking.
