Adaptive Precision Block-Jacobi for High Performance Preconditioning in the Ginkgo Linear Algebra Software

Flegar, Goran; Anzt, Hartwig; Cojean, Terry; Quintana-Ortí, Enrique S. (Association for Computing Machinery, 2021-04)

[EN] The use of mixed precision in numerical algorithms is a promising strategy for accelerating scientific applications. In particular, the adoption of specialized hardware and data formats for low-precision arithmetic ...
Adaptive precision in block-Jacobi preconditioning for iterative sparse linear system solvers

Anzt, Hartwig; Dongarra, Jack; Flegar, Goran; Higham, Nicholas J.; Quintana Ortí, Enrique Salvador (John Wiley & Sons, 2019-03-25)

[EN] We propose an adaptive scheme to reduce communication overhead caused by data movement by selectively storing the diagonal blocks of a block-Jacobi preconditioner in different precision formats (half, single, or ...
