The distance threshold search finds all trajectories within a given distance of a query trajectory. We develop three GPU distance threshold search ...
We develop three indexing schemes and accompanying search algorithms for efficient distance threshold searches on the GPU. We evaluate these implementations and ...

This search involves large numbers of Euclidean moving distance calculations, thus making it a good candidate for execution on manycore platforms such as GPUs.
This search involves large numbers of Euclidean moving distance calculations, thus making it a good candidate for execution on manycore platforms such as GPUs.
The broad finding is that a GPU implementation, provided an appropriate indexing scheme is used, can outperform a multithreaded CPU implementation that uses ...
