    • closedAccess   Exploiting thread-level parallelism in the iterative solution of sparse linear systems 

      Aliaga Estellés, José Ignacio; Bollhöfer, Matthias; Martín Huertas, Alberto F.; Quintana-Orti, Enrique S. Elsevier (2011)
      We investigate the efficient iterative solution of large-scale sparse linear systems on shared-memory multiprocessors. Our parallel approach is based on a multilevel ILU preconditioner which preserves the mathematical ...

    • closedAccess   Extending OpenMP to Survive the Heterogeneous Multi-Core Era 

      Ayguadé, Eduardo; Badía Sala, Rosa María; Bellens, Pieter; Cabrera, Daniel; Durán, Alejandro; Ferrer, Roger; González, Marc; Igual, Francisco; Jiménez González, Daniel; Labarta Mancho, Jesús; Martinell, Luis; Martorell, Xavier; Mayo, Rafael; Pérez, Josep M.; Planas, Judit; Quintana-Orti, Enrique S. Springer US (2010)
      This paper advances the state-of-the-art in programming models for exploiting task-level parallelism on heterogeneous many-core systems, presenting a number of extensions to the OpenMP language inspired in the StarSs ...

    • closedAccess   Leveraging Task-Parallelism in Energy-Efficient ILU Preconditioners 

      Aliaga Estellés, José Ignacio; Dolz, Manuel F.; Martín Huertas, Alberto F.; Mayo, Rafael; Quintana-Orti, Enrique S. Springer Berlin Heidelberg (2012)
      We analyze the energy-performance balance of a task-parallel computation of an ILU-based preconditioner for the solution of sparse linear systems on multi-core processors. In particular, we elaborate a theoretical model ...
