Abstract
Computations on composite overlapping grids require a mix of structured and unstructured operations. We describe a computational framework for parallel computers using data parallel arrays for the structured component grids. The unstructured interpolation is efficiently parallelized outside the data parallel environment using MPI. C++ classes representing abstractions needed are presented as well as results validating the implementation of the interpolation operation.
