Several approaches to the parallelization of a symmetric successive overrelaxation (SSOR)
preconditioner in the Eisenstat modification are considered. This preconditioner
is used for the iterative solving of linear systems resulting from the approximation
of the corresponding variational problems of electromagnetism. The parallelization of
the preconditioner is based on a computational domain decomposition (including the
algebraic one) with a joint matrix reordering. Special efforts are spent to ensure
a high performance of the preconditioner on NUMA-architectures. The numerical results
obtained confirm a high level of performance and scalability of the proposed algorithms.
Keywords:
preconditioners; parallel algorithms; domain decomposition; NUMA-architectures.
