    • closedAccess   Acceleration of PageRank with Customized Precision Based on Mantissa Segmentation 

      Grützmacher, Thomas; Cojean, Terry; Flegar, Goran; Anzt, Hartwig; Quintana-Orti, Enrique S. Association for Computing Machinery (ACM) (2020-03)
      We describe the application of a communication-reduction technique for the PageRank algorithm that dynamically adapts the precision of the data access to the numerical requirements of the algorithm as the iteration converges. ...

    • 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 ...
