Abstract

What does it mean for a computer system to be robust? How can robustness be described? How does one determine if a claim of robustness is true? How can one decide which of two systems is more robust? Parallel computing systems are often heterogeneous mixtures of machines, used to execute collections of tasks with diverse computational requirements. A critical research problem is how to allocate resources to tasks to optimize some performance objective. However, systems frequently have degraded performance due to uncertainties, such as inaccurate estimates of actual workload parameters. It is important for system performance to be robust against uncertainty. To accomplish this, we present a stochastic model for deriving the robustness of a resource allocation. This model assumes that stochastic (experiential) information is available for a parameter whose actual values are uncertain. The robustness of a resource allocation is quantified as the probability that a user-specified level of system performance can be met. We show how to use this stochastic model to evaluate the robustness of resource assignments and to design resource management heuristics that produce robust allocations. The stochastic robustness analysis approach can be applied to a variety of computing and communication system environments, including parallel, distributed, cluster, grid, Internet, cloud, embedded, multicore, content distribution networks, wireless networks, and sensor networks. Furthermore, the robustness model is generally applicable to design problems throughout various scientific and engineering fields.
