Introduction

Algebraic Multigrid Benchmark (AMG) is a parallel algebraic multigrid solver for linear systems arising from problems on unstructured grids. AMG is written in ISO-C. It is an SPMD code which uses MPI and OpenMP threading within MPI tasks. Parallelism is achieved by data decomposition. The driver provided with AMG achieves this decomposition by simply subdividing driver provided with AMG achieves this decomposition by simply subdividing the grid into logical P x Q x R (in 3D) chunks of equal size.
