Optimizing power management in partitioned multicore virtual machine platforms by uniform distribution of a requested power reduction between all of the processor cores

摘要

Handling requests for power reduction by first enabling a request for an amount of power change, e.g. reduction by any partition. In response to the request for power reduction, an equal proportion of the whole amount of power reduction is distributed between each of a set of cores providing the entitlements to the partitions, and the entitlement of the requesting partition is reduced by an amount corresponding to the whole amount of the power change.
