EnergyLB: combinando balanceamento de carga dinâmico com técnicas DVFS para reduzir o consumo de energia
Resumo
A Demanda de Potência e o Consumo de Energia de grandes sistemas são preocupações na área de Computação de Alto Desempenho. Almejando atender a esse desafio nós desenvolvemos um balanceador de carga chamado EnergyLB que considera a carga computacional e a frequência dos núcleos na tomada de decisões quando aplicações iterativas são executadas. Nossa estratégia combina balanceamento de carga dinâmico com DVFS para reduzir a frequência de clock de núcleos subcarregados após a migração das tarefas.Referências
