Abstract
Generally disclosed herein is an approach for dynamically modulating a hardware prefetcher using system software. The hardware prefetcher may be disabled when the amount of the memory bandwidth utilization level is above an upper threshold. The hardware prefetcher may be enabled when the amount of the memory bandwidth utilization level is below a lower threshold. To avoid constantly toggling the hardware prefetcher on and off and allow for smoother transitions, the amount of the memory bandwidth utilization level is observed until it stays above the upper threshold or below the lower threshold for a particular time before the system software changes the latest state of the hardware prefetcher.
