The file system interface provided by today's operating systems has not kept up with available hardware. Consequently, the applications do not take full performance advantage of the current capabilities. This project will explore new software and hardware architectures to improve the storage interface with the potential to provide a uniform, secure and performant interface across a range of storage mechanisms.?To achieve these goals, the project will explore novel kernel- and user-space mechanisms to access storage systems ranging from local persistent memory to remote key-value stores. Further, research thrust will examine means of providing the flexibility of these two storage classes in bus-attached devices such as solid state drives, which are mostly limited to a fixed-size block storage interface. New mechanisms will be evaluated via software implementation in a research operating system and full-system simulation of proposed hardware features.?The rapid adoption of cloud models such as serverless computing has resulted in a wide range of applications which are free of the backwards-compatibility constraints, creating opportunities for novel research in this area to benefit cloud computing systems, which may result in technology transfer. Further, the project will involve and mentor students at the undergraduate, masters, and PhD levels, and in particular will seek to involve masters degree students from a departmental program that actively recruits from under-represented groups.Software developed as part of this project will be made available under an open-source license. When possible, traces collected during this work will be submitted to the trace repository at http://iotta.snia.org. A project website (http://khoury.northeastern.edu/~pjd/nonblock) will be used to make available artifacts, code, and data resulting from this project, including containerized versions of key simulations for reproducibility. The website will be maintained beyond the duration of the project.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.

今天的操作系统提供的文件系统接口已经跟不上可用的硬件。因此，应用程序不能充分利用当前功能的性能优势。该项目将探索新的软件和硬件架构，以改善存储接口，并有可能在一系列存储机制中提供统一、安全和高性能的接口。为了实现这些目标，该项目将探索新的内核和用户空间机制，以访问从本地持久内存到远程键值存储的存储系统。此外，研究重点将研究在总线连接设备（如固态驱动器）中提供这两种存储类的灵活性的方法，这些设备大多限于固定大小的块存储接口。新机制将通过在研究操作系统中的软件实现和对拟议硬件功能的全系统模拟进行评估。无服务器计算等云模型的快速采用产生了广泛的应用程序，这些应用程序没有向后兼容性限制，为该领域的新研究创造了机会，使云计算系统受益，这可能导致技术转让。此外，该项目还将邀请本科生、硕士生和博士生参加并提供指导，特别是邀请积极从代表性不足的群体中招募的系级项目的硕士生参加。作为该项目一部分开发的软件将在开源许可下提供。如有可能，在此工作期间收集的跟踪将提交到跟踪存储库http://iotta.snia.org。项目网站（http：//khoury.northeastern.edu/~pjd/nonblock）将用于提供此项目产生的工件、代码和数据，包括关键模拟的容器化版本，以实现可重复性。这个奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
