Abstract
Nondeterministic Sequential (NDSeq) specifications have been proposed as a means for separating the testing, debugging, and verifying of a program's parallelism correctness and its sequential functional correctness. In this work, we present a technique that, given a few representative executions of a parallel program, combines dynamic data flow analysis and Minimum-Cost Boolean Satisfiability (MinCostSAT) solving for automatically inferring a likely NDSeq specification for the parallel program. For a number of Java benchmarks, our tool NDetermin infers equivalent or stronger NDSeq specifications than those previously written manually.
