How accurate is the estimated result from the simulation points relative to the full simulation result?
To quantify the accuracy of SimPoint, we compute the relative error of the SimPoint estimated results (as described on this page) in comparison to the full simulation result. To do this we take the absolute difference of the two values, and divide by the full simulation result. E.g. SimPoint CPI=2.1, full simulation CPI = 2.0 Relative error = |2.1 2| / 2 = 5% error. We provide a detailed error evaluation of the tool on the full SPEC 2000 CPU suite in error analysis.
