E cient data-parallel spatial join algorithms for pmr quadtrees and R-trees, common spatial data structures, are presented. The domain consists of planar line segment data i.e., Bu...
Abstract. Recent years have witnessed an increasing interest in designing algorithms for querying and analyzing streaming data (i.e., data that is seen only once in a fixed order) ...

Checkpointing of parallel applications can be used as the core technology to provide process migration. Both, checkpointing and migration, are an important issue for parallel appl...
We provide an evaluation of query execution plans (QEP) in the case of queries with one or two spatial joins. The QEPs assume R -tree indexed relations and use a common set of spat...
