9309176 Griffioen This research project to address the issues involved in the design of scalable high-performance distributed file systems based on volatile storage. The flexibility of such system combined with recent technology trends provides an opportunity for exceptional performance and superior resource utilization. The research has four components. First, a new distributed file system abstraction that incorporates both volatile and stable storage into a single abstraction will be investigated. The abstraction allows users to adjust the persistence guarantees of a file to match the requirements of the application, thereby optimizing performance. Second, a novel memory architecture called loosely-coupled memory that provides a massive aggregate memory space for use by the proposed file system will be introduced. The architecture also incorporates asymmetric compression techniques to make effective use of memory and underutilized processing power, and to improve file system access time. Third, a new abstraction and file system architecture into the BM Xinu operating system to verify our design. VM Xinu provides a high-performance, low-latency communication protocol ideal for support of a loosely-coupled memory system. Finally, the file system will be incorporated into the Mach operating system to demonstrate and evaluate our ideas in the context of a large user population. ***

9309176 Griffioen本研究项目旨在解决基于易失性存储的可扩展高性能分布式文件系统设计中涉及的问题。 这种系统的灵活性与最近的技术趋势相结合，为卓越的性能和上级资源利用提供了机会。 该研究有四个组成部分。 首先，一个新的分布式文件系统的抽象，将易失性和稳定存储到一个单一的抽象将被调查。 这种抽象允许用户调整文件的持久性保证以匹配应用程序的需求，从而优化性能。 其次，将介绍一种称为松耦合存储器的新型存储器体系结构，它提供了大量的聚合存储器空间供所提出的文件系统使用。 该体系结构还采用了非对称压缩技术，以有效利用内存和未充分利用的处理能力，并改善文件系统访问时间。 第三，将一个新的抽象和文件系统架构引入到BM Xinu操作系统中来验证我们的设计。 VM Xinu提供了一种高性能、低延迟的通信协议，非常适合支持松耦合内存系统。 最后，该文件系统将被整合到Mach操作系统中，以在大量用户群体的背景下展示和评估我们的想法。 ***
