Abstract

The problem of minimizing average task response time in heterogeneous multiple computer systems with energy constraint is considered. The average task response time in an entire system of multiple computers is formulated as a function of power allocations to the computers. The average task response time is minimized subjected to the constraint that the expected energy consumption of all the computers over certain period of time does not exceed a given energy budget. The minimization problem is solved by finding an optimal power allocation to the computers. An algorithm is developed to solve our optimization problem.
