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.
