Benchmarking the Performance of a Cluster-Based Geospatial Database System

摘要

The advent of inexpensive high performance computing clusters has opened the doorway to a wide range of applications that hitherto had been inconceivable. Such clusters can provide certain applications with a substantial boost in both compute and I/O performance. Therefore, it seems logical that Geographic Information Systems (GIS) applications would be an ideal fit for such systems. This paper presents a scheme to distribute geospatial data across several compute nodes in a cluster. Several variations of this scheme are presented and the performance of each is benchmarked by using various geospatial queries to retrieve the data.
