We consider the management problem for a cluster of three identical servers treating an external request. We assume that each agent has a constant computational speed and we build a deterministic hybrid dynamical model of the overall system. Then, inspired by consensus theory, we propose a centralized control law distributing the computational load among the agents and deciding when to turn on or off each agent, for energy effciency, while ensuring that the queues of each agent asymptotically converge to a desirable level. We prove the properties of the proposed law and highlight some interesting peculiarities in terms of non-uniform convergence.
