A distributed-memory hierarchical solver for general sparse linear systems
Chao Chen, Hadi Pouransari, Sivasankaran Rajamanickam +2
We present a parallel hierarchical solver for general sparse linear systems on distributed-memory machines. For large-scale problems, this fully algebraic algorithm is faster and m…
On the numerical rank of radial basis function kernels in high dimension
Ruoxi Wang, Yingzhou Li, Eric Darve
Low-rank approximations are popular methods to reduce the high computational cost of algorithms involving large-scale kernel matrices. The success of low-rank methods hinges on the…
Fast Low-Rank Kernel Matrix Factorization through Skeletonized Interpolation
Léopold Cambier, Eric Darve
Integral equations are commonly encountered when solving complex physical problems. Their discretization leads to a dense kernel matrix that is block or hierarchically low-rank. Th…
