  • Publication number: 20240095168
    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.

    Abstract: A computing system performs partial cache deactivation. The computing system estimates the leakage power of a cache based on operating conditions of the cache including voltage and temperature. The computing system further identifies a region of the cache as a candidate for deactivation based on cache hit counts. The computing system then adjusts the size of the region for the deactivation based on the leakage power and a bandwidth of a memory hierarchy device. The memory hierarchy device is at the next level to the cache in a memory hierarchy of the computing system.
