Abstract
A mechanism is provided for determining whether to use cache affinity as a criterion for software thread dispatching in a shared processor logical partitioning data processing system. The server firmware may store data about when and/or how often logical processors are dispatched. Given these data, the operating system may collect metrics. Using the logical processor metrics, the operating system may determine whether cache affinity is likely to provide a significant performance benefit relative to the cost of dispatching a particular logical processor to the operating system.
