Restructuring the Tridiagonal and Bidiagonal QR Algorithms for Performance
ACM Digital Library (2014-04)We show how both the tridiagonal and bidiagonal QR algorithms can be restructured so that they be- come rich in operations that can achieve near-peak performance on a modern processor. The key is a novel, cache-friendly ... -
Solving dense generalized eigenproblems on multi-threaded architectures
Elsevier (2012-07)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. ... -
Solving the Schrödinger eigenvalue problem by the imaginary time propagation technique using splitting methods with complex
American Institute of Physics (AIP Publishing LLC) (2013)The Schrödinger eigenvalue problem is solved with the imaginary time propagation technique. The separability of the Hamiltonian makes the problem suitable for the application of splitting methods. High order fractional ...
