Resum
We compare two approaches to compute a fraction of the spectrum of dense symmetric
definite generalized eigenproblems: one is based on the reduction to tridiagonal form,
and the other on the Krylov-subspace iteration. ... [+]
We compare two approaches to compute a fraction of the spectrum of dense symmetric
definite generalized eigenproblems: one is based on the reduction to tridiagonal form,
and the other on the Krylov-subspace iteration. Two large-scale applications, arising in
molecular dynamics and material science, are employed to investigate the contributions
of the application, architecture, and parallelism of the method to the performance of the
solvers. The experimental results on a state-of-the-art 8-core platform, equipped with a
graphics processing unit (GPU), reveal that in realistic applications, iterative Krylovsubspace
methods can be a competitive approach also for the solution of dense problems. [-]
