    • openAccess   A Data-Parallel ILUPACK for Sparse General and Symmetric Indefinite Linear Systems 

      Aliaga Estellés, José Ignacio; Bollhöfer, Matthias; Dufrechou, Ernesto; Ezzatti, Pablo; Quintana-Orti, Enrique S. Springer (2017-05-28)
      The solution of sparse linear systems of large dimension is a critical step in problems that span a diverse range of applications. For this reason, a number of iterative solvers have been developed, among which ILUPACK ...

    • openAccess   Adaptive precision solvers for sparse linear systems 

      Anzt, Hartwig; Dongarra, Jack; Quintana-Orti, Enrique S. ACM (2015)
      We formulate an implementation of a Jacobi iterative solver for sparse linear systems that iterates the distinct components of the solution with different precision in terms of mantissa length. Starting with very low ...

    • closedAccess   Fine-grained bit-flip protection for relaxation methods 

      Anzt, Hartwig; Dongarra, Jack; Quintana-Ortí, Gregorio Elsevier (2019-09)
      Resilience is considered a challenging under-addressed issue that the high performance computing community (HPC) will have to face in order to produce reliable Exascale systems by the beginning of the next decade. As part ...
