A METHOD AND SYSTEM FOR DYNAMIC WORKLOAD ALLOCATION IN A COMPUTING CENTER WHICH OPTIMIZES THE OVERALL ENERGY CONSUMPTION

摘要

A method, computer program and system for assigning a processing task to a computer in a group of computers are described. The method first receives instantaneous temperature and power consumption data collected in the data-center and selects the computers which have the pre-requisite environment execution for which the temperature does not pass a given threshold. A instantaneous efficiency index representing the efficiency of each computer is computed: it takes into account the instantaneous energy consumption and processing throughput determined for that computer. One embodiment consists in selecting the computer with the higher efficiency index. If no computer has a instantaneous temperature under the threshold or if no computer has the efficiency index above a given reasonable value the task is sent for execution to a processing service external to the location of the group of computers.
