On the Performance of an Algebraic Multigrid Solver on Multicore Clusters

  title={On the Performance of an Algebraic Multigrid Solver on Multicore Clusters},
  author={Allison H. Baker and Martin Schulz and Ulrike Meier Yang},
Algebraic multigrid (AMG) solvers have proven to be extremely efficient on distributed-memory architectures. However, when executed on modern multicore cluster architectures, we face new challenges that can significantly harm AMG’s performance. We discuss our experiences on such an architecture and present a set of techniques that help users to overcome the associated problems, including thread and process pinning and correct memory associations. We have implemented most of the techniques in a… CONTINUE READING
