Parallel Algebraic Multigrid Domain Decomposition+
Summary
★Parallel AMG-DD breaking the communication wall★ Algebraic Multigrid (AMG) has optimal computational complexity but the cost of communication limits its scalability on large clusters. Algebraic Multigrid Domain Decomposition (AMG-DD) is an algorithm that trades some additional computations for a significant reduction in communication cost, resulting in superior performance on communication limited systems with high local compute power (e.g. GPU-cluster).
