  We use Energy Packet Network paradigms to investigate energy distribution
problems in a computer system with energy harvesting and storages units. Our
goal is to minimize both the overall average response time of jobs at
workstations and the total rate of energy lost in the network. Energy is lost
when it arrives at idle workstations which are empty. Energy is also lost in
storage leakages. We assume that the total rate of energy harvesting and the
rate of jobs arriving at workstations are known. We also consider a special
case in which the total rate of energy harvesting is sufficiently large so that
workstations are less busy. In this case, energy is more likely to be sent to
an idle workstation. Optimal solutions are obtained which minimize both the
overall response time and energy loss under the constraint of a fixed energy
harvesting rate.
