Estimating the condition number of Chebyshev filtered vectors with application to the ChASE library
Edoardo Di Napoli, Xinzhe Wu
Chebyshev filtered subspace iteration is a well-known algorithm for the solution of (symmetric/Hermitian) algebraic eigenproblems which has been implemented in several application…
Chebyshev Accelerated Subspace Eigensolver for Pseudo-hermitian Hamiltonians
Edoardo Di Napoli, Clément Richefort, Xinzhe Wu
Studying the optoelectronic structure of materials can require the computation of several thousands of the smallest positive eigenpairs of a pseudo-hermitian Hamiltonian. Iterative…
ChASE -- A Distributed Hybrid CPU-GPU Eigensolver for Large-scale Hermitian Eigenvalue Problems
Xinzhe Wu, Davor Davidovic, Sebastian Achilles +1
As modern massively parallel clusters are getting larger with beefier compute nodes, traditional parallel eigensolvers, such as direct solvers, struggle keeping the pace with the h…
A Modified Ising Model of Barabási-Albert Network with Gene-type Spins
Jeyashree Krishnan, Reza Torabi, Edoardo Di Napoli +1
The central question of systems biology is to understand how individual components of a biological system such as genes or proteins cooperate in emerging phenotypes resulting in th…
The LAPW method with eigendecomposition based on the Hari--Zimmermann generalized hyperbolic SVD
Sanja Singer, Edoardo Di Napoli, Vedran Novaković +1
In this paper we propose an accurate, highly parallel algorithm for the generalized eigendecomposition of a matrix pair , given in a factored form $(F^{\ast} J F, G^{\ast}…
ChASE: Chebyshev Accelerated Subspace iteration Eigensolver for sequences of Hermitian eigenvalue problems
Jan Winkelmann, Paul Springer, Edoardo Di Napoli
Solving dense Hermitian eigenproblems arranged in a sequence with direct solvers fails to take advantage of those spectral properties which are pertinent to the entire sequence, an…
