Monitoramento e avaliação do consumo energético em função do poder computacional

Abstract

Recently, attempts to reduce the power consumption of computer systems do not match the increasing demand for resources from hardware increasingly powerful. As an example, can cite the processor clock frequency which stopped being increased due to high energy cost associated with its increment. The introduction of parallelism in processors and the use of volunteers computational resources have been the alternatives found by information society to solve the problem. Such alternatives can maximize the utilization rate of hardware resources, thereby increasing the processing capacity without increasing the energy cost in large proportions. In this context, this paper conducts a study dedicated to evaluating the energy consumption as a function of computational power. The study is through monitoring and evaluation of tests, performed in uniprocessor and multiprocessor computer systems in various configurations.
