An efficient basis set representation for calculating electrons in molecules
Jeremiah R. Jones, Francois-Henry Rouet, Keith V. Lawler +9
The method of McCurdy, Baertschy, and Rescigno, J. Phys. B, 37, R137 (2004) is generalized to obtain a straightforward, surprisingly accurate, and scalable numerical representation…
A distributed-memory package for dense Hierarchically Semi-Separable matrix computations using randomization
François-Henry Rouet, Xiaoye S. Li, Pieter Ghysels +1
We present a distributed-memory library for computations with dense structured matrices. A matrix is considered structured if its off-diagonal blocks can be approximated by a rank-…
An efficient multi-core implementation of a novel HSS-structured multifrontal solver using randomized sampling
Pieter Ghysels, Xiaoye S. Li, Francois-Henry Rouet +2
We present a sparse linear system solver that is based on a multifrontal variant of Gaussian elimination, and exploits low-rank approximation of the resulting dense frontal matrice…
