    • closedAccess   Condensed forms for the symmetric eigenvalue problem on multi-threaded architectures 

      Bientinesi, Paolo; Igual, Francisco; Kressner, Daniel; Petschow, Matthias; Quintana-Orti, Enrique S. Wiley (2011-11-10)
      We investigate the performance of the routines in LAPACK and the Successive Band Reduction (SBR) toolbox for the reduction of a dense matrix to tridiagonal form, a crucial preprocessing stage in the solution of the symmetric ...

    • openAccess   Improved Accuracy and Parallelism for MRRR-Based Eigensolvers -- A Mixed Precision Approach 

      Petschow, Matthias; Quintana-Orti, Enrique S.; Bientinesi, Paolo Society for Industrial and Applied Mathematics (2014)
      The real symmetric tridiagonal eigenproblem is of outstanding importance in numerical computations; it arises frequently as part of eigensolvers for standard and generalized dense Hermitian eigenproblems that are based on ...
