Load Balancing Using MIMO Linear Control

Load balancing is generally a resource allocation problem that can be solved using constraint optimization methods. However, system dynamics are usually not considered. In this paper we propose an optimization algorithm that manages system dynamics using multi-input multi-output dynamic state feedback. In particular, we study the optimization problem in the context of a database memory allocation problem where the cost function value is unknown but the gradient is known. Our studies of a DB2 Universal Database Server in an OLTP benchmarking environment indicate that our approach can be effective in practice.
