Leveraging GPUs for Effective Clause Sharing in Parallel SAT Solving

Nicolas Prevot, Mate Soos, Kuldeep S. Meel

Abstract: The past two decades have witnessed an unprecedented improvement in runtime performance of SAT solvers owing to clever software engineering and creative design of data structures. Yet, most entries in the annual SAT competition retain the core architecture of MiniSat, which was designed from the perspective of single core CPU architectures. Since 2005, however, there has been a significant shift to heterogeneous architectures owing to the impending end of Dennard scaling.
