A definition of synchronization of coupled dynamical systems is provided. We discuss how such a definition allows one to identify a unifying framework for synchronization of dynamical systems, and show how to encompass some of the different phenomena described so far in the context of synchronization of chaotic systems.
Managing large systems in order to guarantee certain behavior is a difficult problem due to their dynamic behavior and complex interactions. Policies have been shown to provide a very expressive and easy way to define such desired behaviors, mainly because they separate the definition of desired behavior from the enforcement mechanism, allowing either one… (More)
Ensuring high reliability of large-scale clusters is becoming more critical as the size of these machines continues to grow, since this increases the complexity and amount of interactions between different nodes and thus results in a high failure frequency. For this reason, predicting node failures in order to prevent errors from happening in the first… (More)
