Abstract
Os aspectos incluem dispositivo de computação, aparelhos e métodos implementados pelo aparelho para implementar múltiplos diretórios de monitoramento divididos em um dispositivo de computação incluindo qualquer quantidade de processadores, qualquer quantidade de domínios de potência, e qualquer quantidade de caches de processador. Por exemplo, vários aspectos podem incluir ativar um primeiro diretório de monitoramento dividido para um primeiro domínio de potência e um segundo diretório dividido para um segundo domínio de potência, em que o primeiro domínio de potência inclui uma primeira pluralidade de caches de processador e o segundo domínio de potência inclui pelo menos uma cache de processador, determinar se todas da primeira pluralidade de caches de processador estão em um estado de baixa potência, e desativar o primeiro diretório de monitoramento dividido em resposta à determinação de que a primeira pluralidade de caches de processador está em um estado de baixa potência. Operações similares podem ser realizadas para um número N de domínios de potência e um número M de caches de processador.
