A parallel implementation of Davidson methods for large-scale eigenvalue problems in SLEPc

Romero Alcalde, Eloy; Román Moltó, José Enrique (Association for Computing Machinery (ACM), 2014-02)

In the context of large-scale eigenvalue problems, methods of Davidson type such as Jacobi-Davidson can be competitive with respect to other types of algorithms, especially in some particularly difficult situations such ...
Computing subdominant unstable modes of turbulent plasma with a parallel Jacobi-Davidson eigensolver

Romero Alcalde, Eloy; Román Moltó, José Enrique (Wiley-Blackwell, 2011-12-10)

In the numerical solution of large-scale eigenvalue problems, Davidson-type methods are an increasingly popular alternative to Krylov eigensolvers. The main motivation is to avoid the expensive factorizations that are often ...
Improvements to SLEPc in releases 3.14-3.18

Jose E. Roman; Alvarruiz Bermejo, Fernando; Campos, Carmen; Dalcin, Lisandro; Jolivet, Pierre; Lamas Daviña, Alejandro (Association for Computing Machinery, 2023-09)

[EN] This short article describes the main newfeatures added to SLEPc, the Scalable Library for Eigenvalue Problem Computations, in the past two and a half years, corresponding to five release versions. The main novelty ...
NEP: A Module for the Parallel Solution of Nonlinear Eigenvalue Problems in SLEPc

Campos, Carmen; Roman, Jose E. (Association for Computing Machinery, 2021-06)

[EN] SLEPc is a parallel library for the solution of various types of large-scale eigenvalue problems. Over the past few years, we have been developing a module within SLEPc, called NEP, that is intended for solving nonlinear ...
Parallel finite element density functional computations exploiting grid refinement and subspace recycling

Young, T. D.; Romero Alcalde, Eloy; Román Moltó, José Enrique (Elsevier, 2013-01)

In this communication computational methods that facilitate finite element analysis of density functional computations are developed. They are: (i) h¿adaptive grid refinement techniques that reduce the total number of ...
