A Compiler for Parallel Finite Element Methods with Domain-Decomposed Unstructured Meshes Jonathan Richard Shewchuk Omar Ghattas School of Computer Science Department of Civil Engineering Carnegie Mellon University Pittsburgh, Pennsylvania 15213 Archimedes is an automated system for finite element methods on unstructured meshes using distributed memory supercomputers. Its components include a mesh generator, a mesh partitioner, and a data-parallel compiler whose input is C augmented with machine-independent operations for finite element computations, and whose output is parallel code for a particular multicomputer. We describe an elegant implementation of domain decomposition and give preliminary performance results.
