A Loop Transformation Algorithm Based on Explicit Data Layout Representation for Optimizing Locality
We present a cache locality optimization technique that can optimize a loop nest even if the arrays referenced have different layouts in memory. Such a capability is required for a...

On Threshold BDDs and the Optimal Variable Ordering Problem
Abstract. Many combinatorial optimization problems can be formulated as 0/1 integer programs (0/1 IPs). The investigation of the structure of these problems raises the following ta...
