Performance Modeling for Performance Autotuning

Dr. Paul Hovland, Argonne National Laboratory, U.S.A.

We describe our efforts in performance modeling in the context of automatic performance tuning.  We consider analytic models constructed through source code analysis, semi-analytic models constructed with a combination of source code analysis and empirical measurement, and fully empirical models.  We describe several uses for performance models in conjunction with autotuning, including surrogate construction for algorithm evaluation, surrogate-based search, and bounds analysis for search space truncation.  We focus on models for performance (execution time), but also describe briefly models for power and energy.
