A partition that is executed by multiple processing nodes. Each node includes multiple cores and each of the cores has a frequency that can be set. A first frequency range is provided to the cores. Each core, when executing the identified partition, sets its frequency within the first frequency range. Frequency metrics are gathered from the cores running the partition by the nodes. The gathered frequency metrics are received and analyzed by a hypervisor that determines a second frequency range to use for the partition, with the second frequency range being different from the first frequency range. The second frequency range is provided to the cores at the nodes executing the identified partition. When the cores execute the identified partition, they use a frequencies within the second frequency range.
