  • Design, tuning and evaluation of parallel multilevel ILU preconditioners 

    Aliaga, José Ignacio; Bollhoefer, Matthias; Martín Huertas, Alberto Francisco; Quintana-Ortí, Enrique Salvador (2008)
    Conference lecture

    In this paper, we present a parallel multilevel ILU preconditioner implemented with OpenMP. We employ METIS partitioning algorithms to decompose the computation into concurrent tasks, which are then scheduled to threads. ...
  • Leveraging Task-Parallelism in Energy-Efficient ILU preconditioners 

    Aliaga, José Ignacio; Dolz Zaragozá, Manuel Francisco; Martín Huertas, Alberto Francisco; Mayo, Rafael; Quintana-Ortí, Enrique Salvador (Springer, 2012)
    Conference lecture

    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 ...
  • Parallelizing dense and banded linear algebra libraries using SMPSs 

    Badia Sala, Rosa Maria; Herrero Zaragoza, José Ramón; Labarta Mancho, Jesús José; Pérez, Josep M.; Quintana-Ortí, Enrique Salvador; Quintana-Ortí, Gregorio (2009-12-25)
    Article
    Restricted access - publisher's policy
    The promise of future many-core processors, with hundreds of threads running concurrently, has led the developers of linear algebra libraries to rethink their design in order to extract more parallelism, further exploit ...
  • Symmetric rank-k update on clusters of multicore processors with SMPSs 

    Badia Sala, Rosa Maria; Labarta Mancho, Jesús José; Marjanovic, Vladimir; Martín Huertas, Alberto Francisco; Mayo, Rafael; Quintana-Ortí, Enrique Salvador; Reyes, Ruymán (IOS Press, 2011)
    Conference lecture
    Open Access
    We investigate the use of the SMPSs programming model to leverage task parallelism in the execution of a message-pas sing implementation of the symmetric rank- k update on clusters equipped with multicore processors. Our ...
