Automatic determination of may/must set usage in data-flow analysis
Data-flow analysis is a common technique for gathering program information for use in performance improving transformations such as register allocation, deadcode elimination, common subexpression elimination, and scheduling. Current tools for generating data-flow analysis implementations enable …

A compiler optimization framework for Concordia parallel C
… example, we showed how to solve the Common Subexpression Elimination (CSE) problem using the optimization framework. To make our optimization framework general yet efficient, we pay special attention on data structures used in our implementation. Sets are the common data structure …

Optimization Techniques for Complex Multi-query Applications
… complex multiple queries which have a lot of common subexpressions (CSEs). As a result, identifying and exploiting the CSEs to improve the query performance is essential in these applications. Multiple query optimization (MQO), which aims to identify the CSEs among multiple queries and exploit …

Automatic physical database design : recommending materialized views
… a search space based on identifying maximum commonalities among queries and on rewriting queries using views. These commonalities are used to define candidate views for materialization from which an optimal or near-optimal set can be chosen as a solution to the view selection problem. Using a …
