Persistent memory is an exciting new technology that bridges the gap between two well-established technologies: main memory, which is fast to access but loses its contents in the event of power loss or hardware failure, and the disk, which is slow to access but retains its contents if the power goes off or the hardware fails. To help programmers write correct programs using persistent memory, programming languages provide a construct called persistent transactions, which help ensure that persistent memory can recover to an understandable state after a power or hardware failure. However, existing algorithms for persistent transactions slow programs significantly because they rely on techniques called crash-consistency mechanisms that are inefficient. The project develops two novel crash-consistency mechanisms that overcome the limitations of prior crash-consistency mechanisms. The project applies these new mechanisms to develop new persistent transaction algorithms. The project evaluates these algorithms empirically in comparison to prior persistent transaction algorithms, on real-world persistent memory programs and platforms. A key insight of the new crash-consistency mechanisms lies in the novel way they leverage technology called hardware transactional memory that is included in Intel processors. The work aims to contribute efficient crash-consistency mechanisms and persistent transaction algorithms that are more efficient than prior approaches and to influence future research in this rapidly developing area.The project aims to improve the performance of a key construct for achieving reliable persistent memory programs. This improvement can help make persistent memory widely practical, by achieving both main memory's performance and the disk's retention of contents in the event of failure. Practical persistent memory will improve programmer productivity and make computing systems faster and more reliable. These benefits in turn will impact society across domains that rely on computing, including science, engineering, transportation, and medicine. To increase impact, the implementations resulting from the project will be made publicly available in addition to published research papers. Undergraduate and graduate courses taught by the PI will incorporate the project's research topics. Workshops organized by the PI will expose undergraduate students, especially students who are members of underrepresented groups, to computing research and grad school. These activities will help to educate a diverse workforce of computer scientists trained in the project's topics and research.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

持久内存是一项令人兴奋的新技术，它弥补了两种成熟技术之间的差距：主内存访问速度快，但在断电或硬件故障时会丢失其内容；磁盘访问速度慢，但在断电或硬件故障时会丢失其内容。如果电源关闭或硬件出现故障，则保留其内容。为了帮助程序员使用持久内存编写正确的程序，编程语言提供了一种称为持久事务的结构，这有助于确保持久内存在电源或硬件故障后可以恢复到可理解的状态。然而，现有的持久事务算法会显着降低程序速度，因为它们依赖于效率低下的称为崩溃一致性机制的技术。该项目开发了两种新颖的崩溃一致性机制，克服了先前崩溃一致性机制的局限性。该项目应用这些新机制来开发新的持久事务算法。该项目在现实世界的持久内存程序和平台上，与之前的持久事务算法进行比较，根据经验评估这些算法。新的崩溃一致性机制的一个关键见解在于它们利用英特尔处理器中包含的称为硬件事务内存的技术的新颖方式。这项工作旨在提供比以前的方法更高效的高效崩溃一致性机制和持久事务算法，并影响这个快速发展领域的未来研究。该项目旨在提高实现可靠持久内存程序的关键结构的性能。通过实现主内存的性能和磁盘在发生故障时保留内容，这一改进可以帮助持久内存广泛实用。实用的持久内存将提高程序员的生产力，并使计算系统更快、更可靠。这些好处反过来将影响依赖计算的各个领域的社会，包括科学、工程、交通和医学。为了增加影响力，除了已发表的研究论文外，该项目的实施结果也将公开。 PI 教授的本科生和研究生课程将纳入该项目的研究主题。 PI 组织的研讨会将使本科生，特别是属于代表性不足群体的学生，接触计算机研究和研究生院。这些活动将有助于培养受过项目主题和研究培训的多元化计算机科学家队伍。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
