    • 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   Toward a modular precision ecosystem for high-performance computing 

      Anzt, Hartwig; Flegar, Goran; Grützmacher, Thomas; Quintana-Orti, Enrique S. Sage (2019-05)
      With the memory bandwidth of current computer architectures being significantly slower than the (floating point) arithmetic performance, many scientific computations only leverage a fraction of the computational power in ...
