Abstract
We discuss Kriging Interpolation on high-performance computers as
a method for spatial data interpolation. We analyse algorithms for
implementing Kriging on high-performance and distributed
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 providing computational servers
for processing data using the data interpolation method we describe.
We describe the project context for this work, which involves
prototyping a data processing and delivery system making use of
on-line data archives and processing services made available on-demand
using World Wide Web protocols.
