Abstract
A computing system performs shared cache allocation to allocate cache resources to groups of tasks. The computing system monitors the bandwidth at a memory hierarchy device that is at a next level to the cache in a memory hierarchy of the computing system. The computing system estimates a change in dynamic power from a corresponding change in the bandwidth before and after the cache resources are allocated. The allocation of the cache resources are adjusted according to an allocation policy that receives inputs including the estimated change in the dynamic power and a performance indication of task execution.
