A hierarchical model of data locality
In POPL 2002, Petrank and Rawitz showed a universal result-finding optimal data placement is not only NP-hard but also impossible to approximate within a constant factor if P = NP...

Permission accounting in separation logic
A lightweight logical approach to race-free sharing of heap storage between concurrent threads is described, based on the notion of permission to access. Transfer of permission be...

Simple relational correctness proofs for static analyses and program transformations
We show how some classical static analyses for imperative programs, and the optimizing transformations which they enable, may be expressed and proved correct using elementary logi...

New results on the computability and complexity of points - to analysis
Given a program and two variables p and q, the goal of points-to analysis is to check if p can point to q in some execution of the program. This well-studied problem plays a cruci...

Discovering affine equalities using random interpretation
We present a new polynomial-time randomized algorithm for discovering affine equalities involving variables in a program. The key idea of the algorithm is to execute a code fragme...
