Abstract:  In some cases application execution time on high performance computing systems can be reduced by finding superior combinations of compiler optimization flags. Machine learning methods can be used to predict good combinations of compiler optimizations for previously unseen programs using the best optimizations found for similar programs whose search space has been explored with random search.  This discussion will describe experience gained setting up and extending the open source cTuning framework and results produced by using the framework to perform application optimization with iterative compilation and machine learning.
