Abstract

We present our study on the simulation methodology for SPECjbb2000. The result shows that CPI can be practically used as a performance metric in place of throughput in the simulation. It is shown that SimPoint can successfully identify phases. With only a small number of clusters the user can reap most of the benefits of clustering analysis. A stationary main phase dominates the execution of the benchmark. We propose a method to accurately measure the CPI for the main phase with only one checkpoint. The error in the result can be quantified with a confidence interval.
