Improving the Performance, Scalability and Reliability of the Linux Operating System

该项目旨在提高Linux操作系统在大型系统上的可伸缩性，而不会影响小型嵌入式系统的性能。它将通过取消特别容易出错的代码(如设备驱动程序)的特权来提高Linux的健壮性和安全性，而不会对性能造成不适当的影响。它将通过使关键组件(如处理器、磁盘和内存调度器)可插拔，并使其策略在用户级别可控，从而提高可配置性并简化调整。它将调查用户级文件系统以及处理器和内存调度的可行性和好处，并将证明这些可以在不影响性能的情况下提高系统可靠性。

This project aims to improve the scalability of the Linux operating system to large systems without loss of performance on small, embedded, systems. It will improve Linux robustness and security by de-privileging particularly error-prone code, such as device drivers, without undue impact on performance. It will improve configurability and ease tuning by making critical components, such as processor, disk and memory schedulers, pluggable and their policies controllable at user level. It will investigate the feasibility and benefits of user-level file systems and processor and memory scheduling and will demonstrate that these can improve system reliability without undermining performance.
