Energy-Efficient Workload Allocation in Distributed HPC System

A vital problem of energy management in a High Performance Computing (HPC) system comprised of remote clusters and data centers is investigated. The paper presents the results of research on energy-efficient management of workload in distributed data centers and computing clusters. The optimisation scheme for allocation of clusters to batches of computing tasks is presented and discussed. The aim is to minimize the energy used by the HPC system, assuming that the required level of quality of services is guaranteed. The results of the performance evaluation of the developed decision system through simulation are presented and discussed.
