摘要

本文描述了可靠性微内核框架(RMK)，它是一个可加载的内核模块，用于提供应用感知的可靠性和动态配置安装在RMK中的可靠性机制。RMK原型是在Linux中实现的，支持应用程序/操作系统故障检测和透明的应用程序检查点。实验结果表明，利用应用程序和系统行为特征的操作系统挂起检测可以实现高覆盖率(实验结果为100%)和低误报率。此外，性能开销可以忽略不计，因为指令计数是在硬件中执行的

An OS-level Framework for Providing Application-Aware Reliability

The paper describes the reliability microkernel framework (RMK), a loadable kernel module for providing application-aware reliability and dynamically configuring reliability mechanisms installed in RMK. The RMK prototype is implemented in Linux and supports detection of application/OS failures and transparent application checkpointing. Experiment results show that the OS hang detection, which exploits characteristics of application and system behavior, can achieve high coverage (100% in our experiments) and low false positive rate. Moreover, the performance overhead is negligible because instruction counting is performed in hardware
