摘要

我们提出了一种新的基于推测的分布式仿真方法，用于复杂系统的可靠性分析，其中系统组件的详细功能仿真对于获得准确的总体结果至关重要。我们的目标示例是一个具有计算节点和单个I/O节点的网络集群。准确的系统可靠性表征是通过对故障存在时I/O子系统行为的详细模拟和对计算节点和交换网络的更抽象的模拟相结合来实现的。获得了可靠性度量，如错误覆盖、错误检测延迟和性能度量，如故障存在时的交付时间。该方法在一个工作站网络上实现，实验结果表明，在同一模型下，该方法比时间扭曲模拟器有显著改进。

Dependability analysis of a cache-based RAID system via fast distributed simulation

We propose a new speculation-based, distributed simulation method for dependability analysis of complex systems in which a detailed functional simulation of a system component is essential to obtain an accurate overall result. Our target example is a networked cluster with compute nodes and a single I/O node. Accurate system dependability characterization is achieved via a combination of detailed simulation of the I/O subsystem behavior in the presence of faults and more abstract simulation of the compute nodes and the switching network. Dependability measures like error coverage, error detection latency and performance measures such as delivery time in the presence of faults are obtained. The approach is implemented on a network of workstations, and experimental results show significant improvements over a Time Warp simulator for the same model.
