Profit Driven Optimizations
Mary Lou Soffa
Department of Computer Science
University of Pittsburgh
Although optimizations have been applied by compilers for over 40 years, much of the research has been devoted to the development of particular optimizations. Certain problems with code optimizations have yet to be adequately addressed, including applying only profitable optimizations, ordering optimizations, selecting optimization configurations and combining optimizations. With the rapidly growing use of cost-sensitive embedded systems and the interest in dynamic optimization, handling these problems is becoming all the more important. In this talk, I will discuss our current work in developing a framework for optimizations that can be used to determine important properties of optimizations, and in particular, the profitability of optimizations. Our unifying framework includes code, optimization and resource models for systematically exploring the application of optimizations. The framework will provide both analytical and experimental models for understanding, predicting and verifying the properties of optimizations (i.e., performance impact and interactions). Also, practical and automatic strategies to drive the application of optimizations based on the models are part of the framework. By applying these model-based optimization strategies, the goal is that optimizing compilers will be able to produce higher quality code and use different paradigms than what is possible with current approaches.
