Performance metrics and models are prerequisites for scientific understanding and optimization. This paper introduces a new footprint-based theory and reviews the research in the past four decades leading to the new theory. The review groups the past work into metrics and their models in particular those of the reuse distance, metrics conversion, models of shared cache, performance and optimization,...
Because of the interference in the shared cache on multicore processors, the performance of a program can be severely affected by its co-running programs. If job scheduling does not consider how a group of tasks utilize cache, the performance may degrade significantly, and the degradation usually varies sizably and unpredictably from run to run. In this paper, we use trace-based program locality analysis...
Many techniques characterize the program working set by the notion of the program footprint, which is the volume of data accessed in a time window. A complete characterization requires measuring data access in all O(n^2) windows in an n-element trace. Two recent techniques have significantly reduced the measurement time, but the cost is still too high for real-size workloads. Instead of measuring...
