Since the dawn of modern computing, the technologies used to build computer systems have stably partitioned into compute (manipulate data), memory (holds data while power is on), and storage (for retaining long-term data). Today a new class of technologies are emerging, namely non-volatile memory (NVM), that promises to disruptively merge the concepts of memory and storage. This work exploits the potential of this disruption by synergistically exploring software and hardware changes with a team led by a systems expert and architects with several foci. The work develops new benchmarks and- through analysis - new designs that enable future computer systems do more work at the same cost or the same work at less cost due to more effective access to NVM. Moreover, the project disseminates its NVM benchmarks and software tools to further the work of others and make NSF dollars more impactful. In more detail, the work develops and analyzes NVM benchmarks with dissimilar roots in file systems, persistent memory, and data stores. It then uses this analysis to develop computer NVM designs to hide latency while ensuring persistence, reduce the cost of coordinating with multiple memory controllers, transmutes ideas from general-purpose graphics processing units (GPUs) for NVM use, explores virtual memory address translation for vast NVMs, and facilitates fast atomic publication of data.

自现代计算诞生以来，用于构建计算机系统的技术已稳定地分为计算（操作数据）、内存（在通电时保存数据）和存储（用于保留长期数据）。如今，一类新技术正在兴起，即非易失性存储器 (NVM)，它有望颠覆性地融合内存和存储的概念。这项工作通过与由系统专家和多个重点架构师领导的团队协同探索软件和硬件变更来开发这种破坏的潜力。 这项工作开发了新的基准，并通过分析开发了新的设计，使未来的计算机系统能够以相同的成本完成更多的工作，或者由于更有效地访问 NVM 而以更低的成本完成相同的工作。此外，该项目还传播其 NVM 基准测试和软件工具，以促进其他人的工作并使 NSF 资金更具影响力。更详细地说，这项工作开发并分析了具有不同根源的文件系统、持久内存和数据存储的 NVM 基准测试。然后，使用此分析来开发计算机 NVM 设计，以隐藏延迟，同时确保持久性，降低与多个内存控制器协调的成本，将通用图形处理单元 (GPU) 的想法转变为 NVM 使用，探索虚拟内存地址转换NVM，并促进数据的快速原子发布。
