In this paper we describe PaMira, a powerful distributed SAT solver. PaMira is based on the highly optimized, sequential SAT engine Mira, incorporating all essential optimization techniques modern algorithms utilize to maximize performance. For the distributed execution an efficient work stealing method has been implemented. PaMira also employs the exchange of conflict clauses between the processes to guide the search more efficiently. We provide experimental results showing linear speedup on a multiprocessor environment with four AMD Opteron processors.
