High-Order Finite-differences on multi-threaded architectures using OCCA
David S. Medina, Amik St-Cyr, Timothy Warburton
High-order finite-difference methods are commonly used in wave propagators for industrial subsurface imaging algorithms. Computational aspects of the reduced linear elastic vertica…
Optimized Schwarz preconditioning for SEM based magnetohydrodynamics
Amik St-Cyr, Duane Rosenberg, Sang Dong Kim
A recent theoretical result on optimized Schwarz algorithms demonstrated at the algebraic level enables the modification of an existing Schwarz procedure to its optimized counterpa…
Multiplicative, Additive and Restricted Additive Optimized Schwarz Preconditioning
Amik St-Cyr, Martin J. Gander, Stephen J. Thomas
We demonstrate that a small modification of the multiplicative, additive and restricted additive Schwarz preconditioner at the algebraic level, motivated by optimized Schwarz metho…
