Abstract

The authors consider the problem of exploiting parallelism to improve the performance of the Ladex spatial index. Their goal is to design a parallel Ladex spatial index mechanism for spatial database systems in order to maximize the throughput of spatial queries. This can be achieved by (a) maximizing parallelism for large region queries, (b) by engaging as few processors and disks as possible on small region queries and point queries, and (c) by balancing the load among different processors in a shared-disk parallel hardware architecture
