Abstract
A method for managing workloads in a multiprocessing computer system is disclosed. Initially, a set of affinity domains is defined for a group of processor cores, wherein each of the affinity domains includes a subset of the processor cores. An affinity measure is defined to indicate that a given workload should be moved to a smaller affinity domain having fewer processor cores. A performance measure is defined to indicate the performance of a given workload. A given workload is determined based on the affinity measure and the performance measure. In response to a determination that a given workload should be moved to a smaller affinity domain based on the affinity measure, the given workload is moved to a smaller affinity domain. In response to a determination that there is a reduction in performance based on the performance measure, the given workload is moved to a larger affinity domain.
