....metric given in Section 3 to multiple specified perturbation parameters. Section 6 presents some experiments that highlight the usefulness of the robustness metric. Section 7 concludes the paper. 2 Related Work Although a number of robustness measures have been studied in the literature (e.g. [4, 8, 9, 13, 18, 19, 22]) those measures were developed for specific systems. Unlike those e#orts, this paper presents a general mathematical formulation of a robustness metric that could be applied to a variety of parallel and distributed systems by following the four step derivation procedure presented in this paper. ....

....The central idea is to provide each task with extra time (defined as slack) to execute so that some level of uncertainty can be absorbed without having to re map. The study does not develop a robustness metric; instead, it implicitly uses slack to achieve robustness. The Ballista project [9] explores the robustness of commercial o# the shelf software against failures resulting from invalid inputs to various software procedure calls. A failure causes the software package to crash when unexpected parameters are used for the procedure calls. The research quantifies the robustness of a ....
