WHISPER is being presented at NVMW '17.
Paper accepted to ASPLOS'17!

WHISPER, or Wisconsin-HPL Suite for Persistence is a comprehensive benchmark suite for emerging persistent memory technologies. Persistent Memory (PM) is non-volatile memory accessed with byte addressability (not just blocks) at low latency (not I/O bus) via regular memory instructions (not system calls). WHISPER captures unique properties of PM applications establishing a firm foundation for the design of future hardware and software systems for persistent memory. It covers a wide variety of interfaces to PM including custom PM key-value stores Echo and Redis, a PM database N-store, PM transactional libraries Mnemosyne and NVML and a PM filesystem PMFS. We developed Eliza and a framework, to analyze WHISPER applications which can easily be used to analyze future PM interfaces.
