Abstract

A parallel program archetype [2] aids in the development of reliable, efficient parallel applications with common computation/communication structures by providing development methods and code libraries specific to the structure. This document presents an archetype for meshspectral computations. It describes the common structure captured by the archetype abstraction, discusses a parallelization strategy for such computations, documents our code library to support this parallelization strategy, and presents a collection of tutorial example application programs. 1 Introduction The mesh-spectral archetype is a combination and generalization of the mesh [5] and spectral [3] archetypes. In this section, we describe the data structures and operations on which this archetype is based and a strategy for parallelizing it. 1.1 Mesh-spectral computations In a mesh-spectral computation: ffl Data is based on 3-dimensional grids (arrays). A computation may contain multiple grids of different di...
