Abstract

sistema e método para controlar energia de unidade de processamento central em uma sistema virtualizado. é revelado um método de controlar dinamicamente a energia dentro de uma unidade central de processamento de míltiplos núcleos e inclui executar uma pluralidade de núcleos virtuais, virtualmente executando uma ou mais tarefas; um ou mais fluxis de execução ou uma combinação dos mesmos nos núcleos virtuais; e executar fisicamente uma ou mais tarefas, um ou mais fluxos de execução, ou uma combinação dos mesmos em um núcleos físico de ordem zero. o método pode incluir ainda receber um grau de paralelismo em uma carga de trabalho de uma pluralidade de núcleos virtuais e determinar se o grau de paralelismo na carga de trabalho dos núcleos virtuais é igual a uma primeira condição de ativação.
