Tiled Algorithms for Matrix Computations on Multicore Architectures
Henricus Bouwmeester
The current computer architecture has moved towards the multi/many-core structure. However, the algorithms in the current sequential dense numerical linear algebra libraries (e.g.…
Nonsymmetric multigrid preconditioning for conjugate gradient methods
Henricus Bouwmeester, Andrew Dougherty, Andrew V. Knyazev
We numerically analyze the possibility of turning off post-smoothing (relaxation) in geometric multigrid when used as a preconditioner in conjugate gradient linear and eigenvalue s…
A Critical Path Approach to Analyzing Parallelism of Algorithmic Variants. Application to Cholesky Inversion
Henricus Bouwmeester, Julien Langou
Algorithms come with multiple variants which are obtained by changing the mathematical approach from which the algorithm is derived. These variants offer a wide spectrum of perform…
Towards an Efficient Tile Matrix Inversion of Symmetric Positive Definite Matrices on Multicore Architectures
Emmanuel Agullo, Henricus Bouwmeester, Jack Dongarra +3
The algorithms in the current sequential numerical linear algebra libraries (e.g. LAPACK) do not parallelize well on multicore architectures. A new family of algorithms, the tile a…
Oxygen diffusion in nanostructured perovskites
P. Glyanenko, Yu. Kamenetsky, A. Nemudry +3
Nonstoichiometric perovskite-related oxides (such as ferrites and cobaltites, etc.) are characterized by fast oxygen transport at ambient temperatures, which relates to the microst…
