Recent developments in GPU execution models and architectures have introduced dynamic parallelism to facilitate the execution of irregular applications where control flow and memory behavior can be unstructured, time-varying, and hierarchical. The changes brought about by this extension to the traditional bulk synchronous parallel (BSP) model also creates new challenges in exploiting the current GPU...
Voronoi diagrams are among the most important data structures in geometric modeling. Among many efficient algorithms for computing 2D Voronoi diagrams, Fortune’s sweepline algorithm (Fortune, 1986 [5]) is popular due to its elegance and simplicity. Dehne and Klein (1987) [8] extended sweepline to sweepcircle and suggested computing a type of transformed Voronoi diagram, which is parallel in nature...
Data warehousing applications represent an emergent application arena that requires the processing of relational queries and computations over massive amounts of data. Modern general purpose GPUs are high core count architectures that potentially offer substantial improvements in throughput for these applications. However, there are significant challenges that arise due to the overheads of data movement...
