项目摘要

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.

自现代计算的曙光以来，用于构建计算机系统的技术已稳定地分配为计算（操纵数据），内存（在打开电源时持有数据）和存储（用于保留长期数据）。如今，新的技术正在出现，即非易失性记忆（NVM），有望破坏性地合并内存和存储的概念。这项工作通过协同探索软件和硬件的变化来利用这种破坏的潜力，该团队由系统专家和建筑师带有多个焦点。这项工作开发了新的基准测试和 - 通过分析 - 新设计，使未来的计算机系统以相同的成本进行更多的工作或相同的工作，由于更有效地访问了NVM，因此以较低的成本进行了相同的工作。此外，该项目将其NVM基准和软件工具传播，以进一步促进他人的工作，并使NSF美元更具影响力。更详细的是，该工作在文件系统，持久内存和数据存储中开发和分析具有不同根的NVM基准。然后，它使用此分析来开发计算机NVM设计以隐藏潜伏期的同时确保持久性，降低与多个内存控制器协调的成本，从通用使用图形处理单元（GPU）转移想法以供NVM使用，探索用于大量NVM的虚拟内存地址转换，并辅助快速的ATOMIC出版物。
