    • 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 ...
