    摘要： A method, system, and computer usable program product for power distribution considering cooling nodes in a data processing environment. A power demand of a data processing environment is determined for a period. The data processing environment includes a set of computing nodes and cooling nodes. A determination is made that the power demand will exceed a limit on electrical power available to the data processing environment for the period if the computing nodes and the cooling nodes in the data processing environment are operated in a first configuration. A first amount of power is redistributed from a cooling node in the data processing environment to a computing node in the data processing environment such that a temperature related performance threshold of a subset of computing nodes is at least met.

    摘要： 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.

    摘要： Mechanisms for dynamically managing core pools are provided. The mechanisms measure the amount of a computational load on a computing device. One way of measuring the load may consist of executing a number of instructions, in a unit of time, with numerous cores of the computing device. The mechanisms compare the number of instructions executed with specific thresholds. Depending on whether the number of instructions is higher or lower than the thresholds, the computing devices may respond by activating and deactivating cores of the computing devices. By limiting execution of instructions of the computing device to a smaller number of cores and switching one or more cores to a lower power state, the devices may conserve power.
