This work extends an existing workload comparison approach used for simulation based metrics to computer system based metrics. We apply this approach using processor hardware counters and compare characterizations of
spec cpu
2000 and
spec cpu
2006, against real (commercial) workloads and other benchmarks collected on the same computer system architecture. Using Independent Component analysis we reduce the many dimensional workload characterization space into a lesser dimensional representative space prior to comparing the distribution of workloads. We find that the
spec cpu
benchmarks are for the most part representative on the identified principal components, with notable exceptions.
