Multi-Dimensional Indexing System Considering Distributions of Sub-indexes and Data
This paper experimentally evaluates the parallel multi-dimensional indexing system indexing data by using several multi-dimensional indexes and retrieving required data from them in parallel. A constant number of data are indexed into a sub-index. The sub-index is inserted into an index in a computa...

| Summary: | This paper experimentally evaluates the parallel multi-dimensional indexing system indexing data by using several multi-dimensional indexes and retrieving required data from them in parallel. A constant number of data are indexed into a sub-index. The sub-index is inserted into an index in a computational node. After the number of sub-indexes in a computational node is evaluated, the area managed by each index is evaluated so that the numbers of sub-indexes become equal, and the data are widely distributed. It is experimentally shown that this method has good performance for skewed data. |
