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 ...
Variable-size batched Gauss-Jordan elimination for block-Jacobi preconditioning on graphics processors

Anzt, Hartwig; Dongarra, Jack; Flegar, Goran; Quintana Ortí, Enrique S. (Elsevier, 2019-01)

[EN] In this work, we address the efficient realization of block-Jacobi preconditioning on graphics processing units (GPUs). This task requires the solution of a collection of small and independent linear systems. To fully ...
