講座內(nèi)容：

Large-scale self-diagnosable distributed multiprocessor systems are useful in providing dependable computing platforms for critical applications, and the performability of such multiprocessor systems rely heavily on the underlying architecture connecting the processors. This topic conducts a survey of progress on the investigation of topological robustness on the multiprocessor system based on (n,k)-star graph. In detail, we will address its algebraic property, and conditional diagnosability, g-extra diagnosability under different models. We will also explore the reliability of subsystem under macro-scale through combinatorial probabilistic model and present a practical analytical method to compute the mean time to failure (MTTF) for subsystem through stochastic process along with some empirical analysis.
