Reproducibility of parallel preconditioned conjugate gradient in hybrid programming environments

Iakymchuk, Roman; Barreda Vayá, Maria; Graillat, Stef; Aliaga, José I.; Quintana Ortí, Enrique Salvador (SAGE Publications, 2020-09)

[EN] The Preconditioned Conjugate Gradient method is often employed for the solution of linear systems of equations arising in numerical simulations of physical phenomena. While being widely used, the solver is also known ...
Reproducibility strategies for parallel preconditioned Conjugate Gradient

Iakymchuk, Roman; Barreda, María; Wiesenberger, Matthias; Aliaga, José I.; Quintana Ortí, Enrique Salvador (Elsevier, 2020-06)

[EN] The Preconditioned Conjugate Gradient method is often used in numerical simulations. While being widely used, the solver is also known for its lack of accuracy while computing the residual. In this article, we aim at ...
