Our approach is to dis-tinguish between data structures that exhibit a predictable versus unpredictable cache behavior. Cache performance of accesses to predictable data structures can be automat-ically and accurately determined by our method whereas we let accesses to unpredictable data structures bypass the cache to simplify and improve the analysis. Through exper-imentation with a number of benchmark programs, we show that a vast majority of data accesses stems from predictable data structures. We analyze what kind of data structure
