项目摘要

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 该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的设计所涉及的问题。这种系统的灵活性与最新的技术趋势相结合，提供了实现卓越性能和卓越资源利用率的机会。该研究有四个部分。首先，将研究一种新的分布式文件系统抽象，它将易失性和稳定存储合并到单个抽象中。该抽象允许用户调整文件的持久性保证以满足应用程序的要求，从而优化性能。其次，将引入一种称为松散耦合内存的新颖内存架构，它提供大量聚合内存空间供所提出的文件系统使用。该架构还结合了非对称压缩技术，以有效利用内存和未充分利用的处理能力，并提高文件系统访问时间。第三，将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 提供高性能、低延迟的通信协议，非常适合支持松散耦合的内存系统。最后，文件系统将被纳入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。 ***
