Hybrid static/dynamic scheduling for already optimized dense matrix factorization
Simplice Donfack, Laura Grigori, William D. Gropp +1
We present the use of a hybrid static/dynamic scheduling strategy of the task dependency graph for direct methods used in dense numerical linear algebra. This strategy provides a b…
Parallel Spherical Harmonic Transforms on heterogeneous architectures (GPUs/multi-core CPUs)
Mikolaj Szydlarski, Pierre Esterie, Joel Falcou +2
Spherical Harmonic Transforms (SHT) are at the heart of many scientific and practical applications ranging from climate modelling to cosmological observations. In many of these are…
Solution of the optimal assignment problem by diagonal scaling algorithms
Meisam Sharify, Stéphane Gaubert, Laura Grigori
We show that a solution of the optimal assignment problem can be obtained as the limit of the solution of an entropy maximization problem, as a deformation parameter tends to infin…
Generalized Filtering Decomposition
Laura Grigori, Frédéric Nataf
This paper introduces a new preconditioning technique that is suitable for matrices arising from the discretization of a system of PDEs on unstructured grids. The preconditioner sa…
