General framework for re-assuring numerical reliability in parallel Krylov solvers: A case of BiCGStab methods
Roman Iakymchuk, Jose I. Aliaga
Parallel implementations of Krylov subspace methods often help to accelerate the procedure of finding an approximate solution of a linear system. However, such parallelization coup…
Compressed Basis GMRES on High Performance GPUs
José I. Aliaga, Hartwig Anzt, Thomas Grützmacher +2
Krylov methods provide a fast and highly parallel numerical tool for the iterative solution of many large-scale sparse linear systems. To a large extent, the performance of practic…
Exploiting nested task-parallelism in the factorization
Rocío Carratalá-Sáez, Sven Christophersen, José I. Aliaga +3
We address the parallelization of the LU factorization of hierarchical matrices (-matrices) arising from boundary element methods. Our approach exploits task-paralleli…
