Long-term Performance Bottleneck Analysis and Prediction

— Identifying performance bottlenecks is important for microarchitects and application developers to produce high performance microprocessor designs and application software. Many techniques are used for this purpose, including simulation, software profiling and hardware event counters. Recently longterm program behavior has been getting more attention from researchers because of its potential applications in system-level, as well as program-level optimizations. In this paper, we study performance bottlenecks from a long-term program behavior viewpoint by classifying dynamic program execution into bottleneck phases - the portions of execution that have similar performance bottlenecks. We propose an event counter based performance model that can accurately estimate the performance cost for critical system events. Based on this model, we propose the bottleneck vector as the basis of long-term performance bottleneck analysis and a runtime bottleneck phase tracking scheme. In addition, ...
