An improved coarse-grained parallel algorithm for computational acceleration of ordinary Kriging interpolation
We propose an improved coarse-grain parallel algorithm of ordinary Kriging. We compare two parallel algorithms derived from improved and traditional approaches. Parallel programs based on MPI are implemented in a distributed memory system. Improved algorithm performances better in both parallel efficiency and scalability. Increasing the problem size enhances the performance of improved algorithm.
