    • Assessing the impact of the CPU power-saving modes on the task-parallel solution of sparse linear systems 

      Aliaga, José Ignacio; Barreda, María; Dolz, Manuel F.; Martín Huertas, Alberto Francisco; Mayo, Rafael; Quintana Ortí, Enrique Salvador (Kluwer Academic Publishers, 2014-12-01)

      Accés restringit per política de l'editorial
      We investigate the benefits that an energy-aware implementation of the runtime in charge of the concurrent execution of ILUPACK—a sophisticated preconditioned iterative solver for sparse linear systems—produces on the ...

    • Iteration-fusing conjugate gradient for sparse linear systems with MPI + OmpSs 

      Barreda, María; Aliaga, José I; Beltran, Vicenç; Casas, Marc (Springer Link, 2020)
      Article
      Accés obert
      In this paper, we target the parallel solution of sparse linear systems via iterative Krylov subspace-based method enhanced with a block-Jacobi preconditioner on a cluster of multicore processors. In order to tackle ...
