An Efficient Parallel Join Algorithm Based On Hypercube-Partitioning
Many parallel join algorithms have been proposed so far but most of which are developed focused on minimizing the disk It0 and CPU costs. The communication cost, however, is also ...

Finding corresponding objects when integrating several geo-spatial datasets
When integrating geo-spatial datasets, a join algorithm is used for finding sets of corresponding objects (i.e., objects that represent the same real-world entity). Algorithms for...
