In this paper, we present measurements of miss ratios for the entire set of SPEC benchmarks for a variety of CPU cache configurations; this study extends earlier work that measured only the performance of the integer (C) SPEC benchmarks. We find that instruction cache miss ratios are generally very low, and that data cache miss ratios for the integer benchmarks are also quite low. Data cache miss ratios for the floating point benchmarks are more in line with published measurements for real workloads. We believe that the discrepancy between the SPEC benchmark miss ratios and those observed elsewhere is partially due to the fact that the SPEC benchmarks are all almost exclusively user state CPU benchmarks run until completion as the single active user process. We therefore believe that SPECmark performance levels may not reflect system performance when there is multiprogramming, time sharing and/or significant operating systems activity.
