As the speed gap widens between CPU and memory, memory hierarchy performance has become the bottleneck for most applications. This is due in part to the difficulty of fully utilizing the deep and complex memory hierarchies found on most modern machines. In the past, various tools on performance tuning and prediction have been developed to improve machine utilization. However, these tools are not effective in practice because they either do not consider memory hierarchy or do so with expensive and machinespecific program simulations. In this paper, we first demonstrate that application performance is now primarily limited by memory bandwidth. With this observation, we describe a new approach based on estimating and monitoring memory bandwidt...
