Multiple Configurations Serving the Same Job Class

Develop an extension of the DART policy and the reconfigurable polling-system model in which a job class can be served by several configurations, potentially at different service rates.

Background

The paper models each job class as being served by exactly one configuration in a strongly connected directed configuration graph. DART selects target configurations, follows shortest reconfiguration paths, and may opportunistically serve jobs at intermediate configurations to control weighted high-percentile sojourn times.

The evaluation explicitly restrictss results to the single-serving-configuration setting. Extending the model and policy to permit multiple configurations to serve the same class, with possibly heterogeneous service rates, is identified as work not addressed by the paper.
