Kriging Interpolation on High-Performance Computers

摘要

Kriging Interpolation on high-performance computers as a method for spatial data interpolation. We analyse algorithms for implementing Kriging on high-performance and distibuted architectures. In addition to a number of test problems, we focus on an application of comparing rainfall measurements with satellite imagery. We discuss our hardware and software system and the resulting performance on the basis of the Kriging algorithm complexity. We also discuss our results in relation to selection of an appropriate execution target according to the data parameter sizes. We consider the implications of prouiding computational seruers for processing data using the data interpolation method we describe. We describe the project context for this work, which inuolues prototyping a data processing and deliucrg system making use of on-line data archiues and processing seruices made auailable on-demand using World Wide Web protocols.
