项目摘要
Emerging Storage Class Memory (SCM) technologies combine the non-volatility of storage devices like hard disks and solid state drives (SSDs) with the ability to access data at byte granularity rather than at a block level. Application developers can focus on a single fine-grained storage abstraction, rather than deal with word-granularity access for DRAM memory and a block interface for file-based disk storage. Accessing data directly from SCM instead of software-arbitrated block access has significant performance advantages, especially for modern data intensive applications based on graph and relation processing. However the use of direct SCM access places a significant burden on the application to achieve transactional and robust execution in the presence of unexpected machines failures and software aborts. The research will identify lightweight, scalable architectural and software techniques for developing robust SCM-based software. The goal is to make the development of software for persistent memory comparable to programming conventional DRAM main-memory by relieving the programmer from the complexities of managing transactional atomicity and persistence. Both hardware solutions based on enhancements to the processor and memory-controller architecture, and software approaches in the form of a lightweight persistence library will be developed. The techniques will be scaled up to handle multiple threads and cores, and scale out to multiple CPU sockets and to distributed clustered architectures.
新兴存储级内存 (SCM) 技术将硬盘和固态硬盘 (SSD) 等存储设备的非易失性与以字节粒度(而不是块级别)访问数据的能力相结合。应用程序开发人员可以专注于单个细粒度存储抽象,而不是处理 DRAM 内存的字粒度访问和基于文件的磁盘存储的块接口。直接从 SCM 访问数据而不是软件仲裁的块访问具有显着的性能优势,特别是对于基于图形和关系处理的现代数据密集型应用程序。然而,在出现意外的机器故障和软件中止的情况下,使用直接 SCM 访问给应用程序带来了沉重的负担,无法实现事务性和稳健的执行。该研究将确定轻量级、可扩展的架构和软件技术,用于开发强大的基于 SCM 的软件。 目标是通过将程序员从管理事务原子性和持久性的复杂性中解放出来,使持久性存储器的软件开发与传统 DRAM 主存储器的编程相媲美。将开发基于处理器和内存控制器架构增强的硬件解决方案以及轻量级持久性库形式的软件方法。这些技术将扩展到处理多个线程和核心,并扩展到多个 CPU 插槽和分布式集群架构。
