    • closedAccess   A customized precision format based on mantissa segmentation for accelerating sparse linear algebra 

      Grützmacher, Thomas; Cojean, Terry; Flegar, Goran; Göbel, Fritz; Anzt, Hartwig Wiley (2019)
      In this work, we pursue the idea of radically decoupling the floating point format used for arithmetic operations from the format used to store the data in memory. We complement this idea with a customized precision memory ...

    • 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. ...

    • closedAccess   Load-balancing Sparse Matrix Vector Product Kernels on GPUs 

      Anzt, Hartwig; Cojean, Terry; Yen-Chen, Chen; Dongarra, Jack; Flegar, Goran; Nayak, Pratik; Tomov, Stanimire; Tsai, Yuhsiang M.; Wang, Weichung Association for Computing Machinery (ACM) (2020-03)
      Efficient processing of Irregular Matrices on Single Instruction, Multiple Data (SIMD)-type architectures is a persistent challenge. Resolving it requires innovations in the development of data formats, computational ...
