Scaling of the PARSEC benchmark inputs

A good benchmark suite should provide users with inputs that have multiple levels of fidelity. We present a framework that takes the novel view that benchmark inputs should be considered approximations of their original, full-sized inputs. The paper demonstrates how to use the proposed methodology to create several simulation input sets for the PARSEC benchmarks and how to quantify and measure their approximation error. We offer guidelines that PARSEC users can use to choose suitable simulation inputs for their scientific studies in a way that maximizes the accuracy of the simulation subject to a time constraint.
