AbstractThis paper presents a technique for accelerating the evaluation of exact geometric predicates using CPU and GPU parallel computing. These predicates are important, for example, in GIS applications. The algorithm implemented as a case study in this paper presented a speedup of up to 289 times (if only the time spent evaluating the geometric predicates was considered) and up to 40 times considering the total running-time of the algorithm (when compared against the sequential implementation).
